Description

Technical Field

[0001] The present invention relates to a test method and apparatus for evaluating cognitive decline.

Background Art

[0002] As the aging society continues, the number of dementia patients is increasing rapidly. However, there is no treatment for dementia. Therefore, the most innovative measure against dementia is to detect mild cognitive impairment, which is highly likely to develop into dementia, at an early stage and perform preventive treatment. Mild cognitive impairment refers to the state of a high-risk group in the pre-dementia stage. It has been reported that about 10 to 15% of patients with mild cognitive impairment develop dementia.

[0003] However, there is no standardized diagnostic method for mild cognitive impairment, and doctors diagnose patients face-to-face and comprehensively examine and judge the patient's condition. Conventional tests for evaluating cognitive decline are mainly composed of tests for evaluating memory, and are effective in evaluating Alzheimer's dementia characterized by memory decline. However, there is a problem that the accuracy decreases when evaluating other dementias characterized by cognitive decline other than memory.

[0004] The background art described above is technical information that the inventor possessed for deriving the present invention or acquired in the process of deriving the present invention, and is not necessarily prior art publicly disclosed to the general public before the filing of the present invention.

Best Mode for Carrying Out the Invention

[0019] The advantages and features of the present invention, and the method for achieving them, will become clear by referring to the embodiments described in detail together with the accompanying drawings. However, the present invention is not limited to the embodiments presented below, and can be implemented in various different forms, and should be understood to include all conversions, equivalents, and alternatives included in the spirit and technical scope of the present invention. The embodiments presented below are provided to complete the disclosure of the present invention and to fully inform those with ordinary knowledge in the technical field to which the present invention pertains of the scope of the invention. In the description of the present invention, if it is determined that a specific description of related known technologies may impede the gist of the present invention, the detailed description thereof will be omitted.

[0020] The terms used in this application are merely used to describe specific embodiments and are not intended to limit the present invention. Singular expressions include plural expressions unless the context clearly indicates otherwise. In this application, terms such as "including" or "having" are used to specify the presence of the features, numbers, steps, operations, components, parts, or combinations thereof described in this specification, and it should be understood that the presence or addition of one or more other features, numbers, steps, operations, components, parts, or combinations thereof is not precluded in advance. Terms such as first, second, etc. can be used to describe various components, but the components should not be limited by the above terms. The above terms are only used for the purpose of distinguishing one component from another.

[0021] Furthermore, in this application, a "unit" can be a hardware component such as a processor or a circuit and / or a software component executed by a hardware component such as a processor.

[0022] Hereinafter, embodiments according to the present invention will be described in detail with reference to the accompanying drawings. When describing with reference to the accompanying drawings, the same or corresponding components will be given the same drawing numbers, and redundant descriptions thereof will be omitted.

[0023] FIG. 1 is an exemplary diagram of an inspection environment for evaluating cognitive function decline according to this embodiment. Referring to FIG. 1, an inspection environment 1 for evaluating cognitive function decline can include an inspection device 100 (hereinafter referred to as the inspection device) for evaluating cognitive function decline, a user terminal 200, and a network 300.

[0024] The inspection device 100 can execute an inspection process of inspecting how well a mission presented for each of a plurality of inspection items for a user is performed and calculating inspection scores for each of the plurality of inspection items. In this embodiment, the inspection process can be expressed as inspection steps in the claims described later.

[0025] In this embodiment, the inspection device 100 can execute an inspection process including a first inspection process to a tenth inspection process.

[0026] The first inspection process can include a process of executing an inspection for a first inspection item that evaluates how well a word belonging to a predetermined presentation category is spoken within a limited time (for example, 30 seconds) and a drawing of a pattern instructed within the limited time is performed, and calculating a first inspection score. Here, the first inspection item can include a fluency test.

[0027] The fluency test can be performed to measure the cognitive flexibility that constitutes the executive function. It can be said that the fluency test is an examination that evaluates to what extent cognitive flexibility is naturally calculated within a limited time. The fluency test can include a language fluency test that gives a category task and a spelling task within a given time and calculates as many words as possible, and a visual perception fluency test that draws as many figures as possible by connecting given points. Language fluency requires both language and executive function, and patients with frontotemporal dementia and progressive non-fluent aphasia often tend to show significant impairment in both types of language fluency and tasks.

[0028] The first test process can include a process of performing a test on a first test item that evaluates to what extent the utterance of words corresponding to a given presentation category is accomplished within a first time limit and calculating a first test score. Here, the first - 1 test item can include a language fluency test. From this, the first test process can include a process of performing a language fluency test on the user and calculating a first test score.

[0029] The differences between the fluency test included in the first test process according to this embodiment and the conventional fluency test can be as follows. In the conventional fluency test, the examiner wrote down the words spoken by the user on the test paper. On the other hand, in the fluency test according to this embodiment, the content spoken by the user is recorded using a voice recognition module (not shown), converted into text in real time, and then based on this, a fluency evaluation model is applied to evaluate the degree of the user's language fluency. By weighting in the process of converting to text using the voice recognition module, it is possible to prevent the user's response from being inaccurately texturized. The words that the user has to respond with are words corresponding to a specific category, such as animals, fruits, clothes, etc., and any category can be possible as long as it can include a plurality of noun words.

[0030] The process of scoring and interpreting the fluency test included in the first inspection process is as follows. The number of words responded during the first predetermined time (for example, 30 seconds) can be utilized as the score. It is possible to count and score not only the total number of words spoken during the first predetermined time but also the number of words responded in units of the second predetermined time (for example, various times such as 5 seconds). For the number of words responded in the first half (for example, up to 15 seconds) of the first predetermined time, a first weight can be assigned for scoring, and for the number of words responded in the second half (for example, from 16 to 30 seconds) of the first predetermined time, a second weight can also be assigned for scoring. Here, the first weight can be generated by multiplying the number of words responded by a first value (for example, 2), and the first value is not fixed at 2 but can be any one of the numbers between 1.5 and 2. Also, the second weight can be generated by multiplying the number of words responded by a second value (for example, 1.5), and the second value is not fixed at 1.5 but can be any one of the numbers between 1.5 and 2.

[0031] The second inspection process can be executed after the execution of the first inspection process is completed. The second inspection process includes a process of informing clues of a predetermined category to learn words or pictures and evaluating how much of the learned words or pictures are remembered after a predetermined time (for example, 20 minutes) has passed, and calculating a second inspection score. Here, the second inspection item can include a language clue memory test.

[0032] The formation of long-term memory including episodic memory can be formed through the processes of 1) memorization or encoding, 2) storage and retention, and 3) retrieval. Memory evaluation can grasp the presence or absence of damage, the degree of damage, or the characteristics of damage of episodic memory based on a detailed and comprehensive evaluation for these three steps. By determining whether it is a retrieval failure or a problem of memory strategy through a language clue memory test, the memory function can be accurately grasped. Furthermore, the language clue memory test can have diagnostic value in identifying the type of dementia.

[0033] In this embodiment, the second inspection process can include a second - 1 inspection process and a second - 2 inspection process.

[0034] The second - 1 inspection process can include a process of performing an inspection on a second - 1 inspection item that evaluates to what extent the ability to learn words or pictures by being informed of clues of a predetermined category is achieved, and calculating a second - 1 inspection score. Here, the second - 1 inspection item can include a learning inspection among the language clue memory inspections. Thus, the second - 1 inspection process can include a process of performing a learning inspection among the language clue memory inspections on the user and calculating a second - 1 inspection score.

[0035] The second - 2 inspection process can be executed after the execution of the second - 1 inspection process is completed and a predetermined time has elapsed. In this embodiment, other inspection processes can be executed from the time when the execution of the second - 1 inspection process is completed to a predetermined time. For example, after the execution of the second - 1 inspection process is completed, instead of executing the second - 2 inspection process, after the execution of the second - 1 inspection process is completed and the third inspection process is executed, the second - 2 inspection process can be executed.

[0036] The second - 2 inspection process can include a process of performing an inspection on a second - 2 inspection item that evaluates to what extent the words or pictures learned in the second - 1 inspection process are remembered after a predetermined time has elapsed, and calculating a second - 2 inspection score. Here, the second - 2 inspection item can include a recognition inspection among the language clue memory inspections. Thus, the second - 2 inspection process can include a process of performing a recognition inspection among the language clue memory inspections on the user and calculating a second - 2 inspection score.

[0037] In the language cue memory test included in the second test process according to this embodiment, short-term memory and long-term memory can be formed through the processes of 1) memorization or encoding, 2) storage and retention, and 3) recall. Also, based on a detailed and comprehensive evaluation of the above three processes, a memory evaluation can be performed, including the presence or absence of damage to short-term memory, the degree or characteristics of the damage, etc. Through the language cue memory test according to this embodiment, the memory function can be accurately grasped, and the diagnostic value can be ensured when evaluating the type of dementia. Here, being able to accurately grasp the memory function can include grasping whether it is a problem of recall failure or a problem of memory strategy, etc.

[0038] The differences between the language cue memory test included in the second test process according to this embodiment and the conventional language cue memory test can be as follows. The conventional language cue memory test can be said to be a test that calls multiple words or pictures and checks how many words can be reproduced. However, the language cue memory test according to this embodiment provides a cue indicating the category to which the word belongs to conduct learning, and can ask questions while indicating the category to which the word belongs even in free recall.

[0039] Through the language cue memory test included in the second test process according to this embodiment, the normal group, mild cognitive impairment, and the normal group and Alzheimer's disease dementia can be evaluated. The language cue memory test according to this embodiment can show a significant correlation with the gray matter volume of the parahippocampus, which is a brain region related to the memory of illustrations. Therefore, the language cue memory test according to this embodiment can accurately evaluate language memory ability in a short time.

[0040] In this embodiment, the language cue memory test included in the second test process can be developed into a word interference memory test. The word interference memory test can be said to be a language memory test that measures recent memory based on the list-learning paradigm. The list-learning paradigm is a paradigm widely used for recent memory evaluation and can usually be configured by a procedure of memorizing a series of word lists and then recognizing or reproducing them. The word interference memory test can first measure the ability to recognize the learned words (maximum learning amount) after the first word list (list A, hereinafter referred to as the first list) is presented in reverse. Next, a new word list (list B, hereinafter referred to as the second list) that is semantically associated with the first word list (list A) is presented, and the ability to recognize the newly learned words (interference suppression) can be measured. When learning and recalling the second list, the first list learned in the previous step will affect the performance of the word interference memory test while causing semantic interference, which can be called proactive semantic interference. It is understood that proactive semantic interference is caused by problems in the characteristic memory storage and retrieval processes in Alzheimer's dementia and is known as an important cognitive marker for predicting very early Alzheimer's dementia. The word interference memory test can be configured to sensitively detect possible memory problems manifested in early Alzheimer's disease dementia by measuring the ability to suppress proactive semantic interference and distinguish new information, together with the maximum learning amount.

[0041] The conventional inspection, the LASSI-L (Loewenstein-Acevedo Scales for Semantic Interference and Learning), reproduces a total of 15 words that fall into one of three semantic categories. However, the word interference memory test according to this embodiment reduces the total number of words to be memorized to 8, taking into account the overall educational background and daily functional level of the elderly in Korea. Also, the concepts of a shopping list and a shopping basket, which are familiar to the elderly in Korea, are applied, and it is composed of concrete words that people are familiar with. Furthermore, in order to enable easy scoring and quantification in a digital environment, instead of the reproduction paradigm (the method of directly recalling and speaking the words to be memorized) used in the conventional test, a recognition paradigm (the method of judging whether the presented word is the memorized word by looking at it) is applied. Also, at the time of recognition of the second list, it is devised so that proactive semantic interference can be measured even within the recognition paradigm by presenting as non-target words that the words included in the first list must be excluded.

[0042] The scoring process and interpretation of the word interference memory test are as follows. First, the recognition score for the first list, the number of correct "yes" (true positive) responses, and the number of correct "no" (true negative) responses can be calculated. Here, the recognition score is one embodiment, and it can be calculated by subtracting a reference value (e.g., 4) from the combined value of the number of correct "yes" (true positive) responses and the number of correct "no" (true negative) responses. Second, the recognition score for the second list, the number of correct "yes" (true positive) responses, the number of correct "no" (true negative) responses, and the number of false positive errors can be calculated. Third, the total time required for the word interference memory test can be calculated. As a result of the scoring of the word interference memory test, it can be evaluated that the higher the overall recognition score, the better the language's up-to-date memory ability. The higher the recognition score for the first list, the higher the maximum learnable language memory ability can be evaluated. The higher the recognition score for the second list, the better the ability to suppress proactive interference can be evaluated. The more false positive errors for the second list, the more vulnerable to the influence of proactive semantic interference can be interpreted.

[0043] The third test process can be executed after the execution of the second - 1 test process is completed. The third test process includes performing a test on a third test item that evaluates how accurately and quickly any number that matches the presented symbol image can be selected within a predetermined time limit (e.g., 45 seconds) when looking at the presented symbol image, and calculating a third test score. Here, the third test item can include a symbol - number matching test. Thus, the third test process can include a process of performing a symbol - number matching test on the user and calculating a third test score.

[0044] The processing speed belonging to the execution function can be evaluated by quickly and accurately skimming visual information and identifying it in order. The symbol-digit matching test according to this embodiment can measure visual-motor processing speed, short-term visual memory learning ability, cognitive flexibility, attention, concentration, and synchronization. The symbol-digit matching test is a test in which, looking at the symbols displayed in the center of the screen, one has to find and touch the number associated with the above-mentioned symbols from the number board at the bottom of the screen. A total of n symbols are alternately presented as the symbols displayed in the center of the screen, and the numbers presented at the bottom are associated with one symbol.

[0045] The differences between the symbol-digit matching test included in the third test process according to this embodiment and the conventional symbol-digit writing test can be as follows. The conventional symbol-digit matching test is implemented in a paper-pen test method, in which, looking at the number-symbol table connected at the top of the paper, one handwrites the symbol matching the corresponding number in the blank under the number written in the response part at the bottom. The symbol-digit matching test according to this embodiment is a method in which one of the symbols within the symbol set is displayed in the center of the screen, and one touches the number matching the symbol in the response part where the number-symbol is connected below it. The method for generating the symbol set displayed in the center of the screen is as follows. The symbol can be generated by a combination of four vertices that can be formed in a square shape and all straight lines and curves passing through the midpoints of the four vertices. Since the conventional symbol-digit writing test creates answers using a writing instrument, writing ability may be required in some cases. However, the symbol-digit matching test according to this embodiment can focus on the function of processing visual information. The symbols used in the symbol-digit matching test according to this embodiment consider the copyright of existing symbols and cannot be verbalized, and simple newly created symbols can be applied. In the initial questions, it can be configured to select symbols that are close in distance and arranged at an easy difficulty level. As one progresses to the later questions, it can be configured to search for all symbols to increase the difficulty level.

[0046] The scoring process and interpretation of the symbol-digit matching test included in the third inspection process are as follows. The indicators utilized for scoring can include: 1) the number of digits touched within the given time, 2) the number of digits touched that are connected to the symbol displayed in the center of the screen within the given time, 3) the number of digits touched that are not connected to the symbol displayed in the center of the screen within the given time, and 4) the average time and standard deviation required to touch each digit button.

[0047] The fourth inspection process can be executed after the execution of the second - 2 inspection process is completed. The fourth inspection process can include a process of learning a predetermined presented image and performing an inspection on a fourth inspection item that evaluates how well the learned presented image is remembered after a predetermined time (for example, 20 minutes) has elapsed, and calculating a fourth inspection score. Here, the fourth inspection item can include a visual schematic memory test.

[0048] The Free and Cued Selective Reminding Test developed by Buschke (1984) is a language memory test that provides cues related to categories of words, generates associations for recall during the learning process, and utilizes them during reproduction. Memory tests based on traditional free recall tasks cannot distinguish between a decrease in efficiency and impairment of memory storage due to damage to memory structures, such as the use of inefficient strategies during the memory process and a decrease in processing capacity. Also, rather than the poor performance of the free recall task being a characteristic of dementia, similar results can be observed in aging and depression. However, impairment in the cued recall task can be characteristic of the early diagnosis of Alzheimer's disease. Only by including the process of categorizing multiple words into one semantic cluster and immediately reproducing them during the learning process, which is the encoding step, can we prevent a decrease in the efficiency of the encoding process and detect the problem of memory decline itself due to abnormalities in memory structures. Memory tests using such cued recall tasks mostly use word stimuli and semantic cues. However, picture stimuli can evaluate the visual perception ability of patients and are more familiar and accessible stimuli for illiterate elderly people compared to word stimuli. In the visual schematic memory test according to this embodiment, a visual language memory task is configured using picture stimuli, and the efficiency of memory is enhanced using picture stimuli and schematic cues. As a result of the research, the immediate free recall in the visual schematic memory test according to this embodiment is a task that successfully differentiates three groups: normal, mild cognitive impairment, and Alzheimer's disease. The learning task most successfully distinguished Lewy body dementia from other groups in terms of the attribute of visual recognition. In the visual schematic memory test according to this embodiment, differences between groups were well represented in a small test that is more affected by encoding than by memory storage and retention, such as learning, immediate cued recall, and immediate free recall.

[0049] In this embodiment, the fourth test process can include a fourth - 1 test process and a fourth - 2 test process.

[0050] The 4-1 inspection process can be executed after the execution of the 2-2 inspection process is completed. The 4-1 inspection process includes a process of presenting a default first presentation image and inputting visual perception stimuli through a process of grasping the number of colors in the first presentation image, and can include a process of calculating the 4-1 inspection score. Here, the 4-1 inspection item can include a learning inspection among visual diagram memory inspections. Thereby, the 3-1 inspection process can include a process of performing a learning inspection among visual diagram memory inspections on the user and calculating the 4-1 inspection score.

[0051] The 4-2 inspection process can be executed after the execution of the 4-1 inspection process is completed and a predetermined time has elapsed. In the present embodiment, other inspection processes can be executed from the time when the execution of the 3-1 inspection process is completed to a predetermined time. For example, after the execution of the 4-1 inspection process is completed, instead of executing the 4-2 inspection process, the 5th inspection process to the 7th inspection process can be executed first, and then the 4-2 inspection process can be executed for the first time. In the present embodiment, the execution procedure of the inspection process can be as follows. First, execute the 1st inspection process, then execute the 2-1 inspection process, then execute the 3rd inspection process, then execute the 2-2 inspection process, then execute the 4-1 inspection process, then execute the 5th inspection process to the 7th inspection process in sequence, then execute the 4-2 inspection process, then execute the 3-2 inspection process, and then execute the 8th inspection process to the 10th inspection process in sequence.

[0052] In the present embodiment, it is disclosed that the 2-2 inspection process must be executed after the execution of the 3rd inspection process is completed, and the 4-2 inspection process must be executed after the execution of the 7th inspection process is completed, but it is not limited thereto. That is, the 2-2 inspection process and the 4-2 inspection process can also be executed after the execution of any one of the 3rd process to the 10th inspection process is completed.

[0053] The 4-2 inspection process can include a process of performing an inspection on a 4-2 inspection item that evaluates how well the presented image learned in the 4-1 inspection process is remembered after a predetermined time has elapsed, and calculating a 4-2 inspection score. Here, the 4-2 inspection item can include a recognition test among visual diagrammatic memory tests. Accordingly, the 4-2 inspection process can include a process of performing a recognition test among visual diagrammatic memory tests on the user and calculating a 4-2 inspection score.

[0054] The differences between the visual diagrammatic memory test included in the 4th inspection process according to this embodiment and the conventional visual diagrammatic memory test can be as follows. The visual diagrammatic memory test according to this embodiment can eliminate interference by semantic memory using abstract images that cannot be verbalized. Also, the images can be configured as one set by varying in color, pattern, and degree of overlap. Also, when performing the recognition test among visual diagrammatic memory tests, images included in the same set as the learned images can be presented as interference images. Also, by arbitrarily selecting and presenting images within a set containing the same cues, the learning effect of selecting familiar images due to past test executions can be eliminated.

[0055] The 5th inspection process can be executed after the execution of the 4-1 inspection process is completed. The 5th inspection process can include a process of performing an inspection on a 5th inspection item that evaluates whether the predetermined presented word and the color of the predetermined presented word are accurately pronounced, and calculating a 5th inspection score. Here, the 5th inspection item can include a Stroop test.

[0056] The Stroop test can measure the ability to suppress a reaction unrelated to the target reaction and maintain the target. The Stroop test can be an efficient index for distinguishing between dementia patients and normal elderly people, as the difference in the test execution ability between dementia patients and normal elderly people appears significantly.

[0057] In this embodiment, the fifth inspection process can include a fifth-1 inspection process and a fifth-2 inspection process.

[0058] The fifth-1 inspection process can include a process of performing an inspection on a fifth-1 inspection item that evaluates whether a given word is spoken correctly and calculating a fifth-1 inspection score. Here, the fifth-1 inspection item can include a first Stroop test. Accordingly, the fifth-1 process can include a process of performing the first Stroop test on a user and calculating a fifth-1 inspection score.

[0059] The fifth-2 inspection process can include a process of performing an inspection on a fifth-2 inspection item that evaluates whether the color of a given presented word is spoken correctly and calculating a fifth-2 inspection score. Here, the fifth-2 inspection item can include a second Stroop test. Accordingly, the fifth-2 process can include a process of performing the second Stroop test on a user and calculating a fifth-2 inspection score.

[0060] The differences between the Stroop test included in the fifth inspection process according to this embodiment and the conventional Stroop test can be as follows. The conventional Stroop test was a method of performing the test on test paper, continuously reading out the presented words, and counting the number of words correctly read to calculate the test score. However, the Stroop test according to this embodiment can include a word reading task of selecting the same word as the word written with the color name and a color reading task of selecting the word that matches the color of the word. The Stroop test according to this embodiment shortens the execution time in consideration of the time that can show a significant test result and can evaluate the number of positive responses during the execution time.

[0061] The sixth inspection process can be executed after the execution of the fifth inspection process is completed. The sixth inspection process can include a process of performing an inspection on a sixth inspection item that evaluates whether to recognize the emotional state shown in a predetermined face presentation image, and calculating a sixth inspection score. Here, the sixth inspection item can include a face emotion inspection. Thereby, the sixth inspection process can include a process of performing a face emotion inspection on a user and calculating a sixth inspection score.

[0062] Generally, dementia patients may develop emotional recognition disorders due to changes in cognitive functions. In addition, dementia patients may have difficulty in emotional exchanges with others compared to healthy people, and there may also be a decrease in empathy in interpersonal relationships. In particular, frontotemporal dementia (FTD) may show changes in behavior in interpersonal relationships, such as apathy, errors in social processing methods, and damage to social recognition. In addition, frontotemporal dementia may have a decrease in facial emotion recognition compared to the normal group. In contrast, the face identification test according to this embodiment provides a plurality of first face presentation images including six basic emotions (happy, scared, sad, angry, bitter, surprising) and a plurality of second face presentation images without emotions, that is, expressionless, and can confirm whether to sensitively notice the emotions included in each expression.

[0063] The differences between the face emotion inspection included in the sixth inspection process according to this embodiment and the conventional face emotion inspection can be as follows. The conventional face identification test was a method of searching for accurate emotions by looking at facial expression photos. However, the face identification test according to this embodiment can present the intensity of emotions step by step and evaluate the matching emotions. In addition, the face emotion inspection can distinguish the emotions between weak emotions and strong emotions, and can level the difference between positive emotions and negative emotions. Also, the difference score (contrast) calculated by the face identification test can be said to be useful for differentiating between major depressive disorder and FTD. The face identification test can present stimuli with a balanced male-female ratio in order to eliminate gender bias towards stimuli.

[0064] The seventh inspection process can be executed after the execution of the sixth inspection process is completed. The seventh inspection process includes a process of performing an inspection on a seventh inspection item that evaluates how accurately and quickly a number presented within a preset time limit is selected, and presenting a number and a day of the week and evaluating how accurately and quickly the day of the week corresponding to the number is selected, and calculating a seventh inspection score. Here, the seventh inspection item can include a Trail Making Test.

[0065] The Trail Making Test can be a test created to evaluate visual concepts and visual-motor abilities. The Trail Making Test can include a number connection test and a number-alphabet connection test. Here, the number-alphabet connection test is a test of drawing lines to connect circles numbered with numbers or lettered with alphabetic characters in turn according to their respective orders. The Trail Making Test may comprehensively require visual perception ability, visual exploration, movement speed, complex visual scanning, agility, etc. Also, the number-alphabet connection test can require the ability to maintain cognitive function conversion such as set-shifting ability, inhibitory reversal, and two types of parallel thinking.

[0066] In this embodiment, the seventh inspection process can include a seventh-1 inspection process and a seventh-2 inspection process.

[0067] The seventh-1 inspection process includes a process of performing an inspection on a seventh-1 inspection item that evaluates how accurately and quickly an arbitrary number started and displayed within the seventh-1 time limit is selected and how accurately and quickly other presented numbers are selected in descending or ascending order, and calculating a seventh-1 inspection score. Here, the seventh-1 inspection item can include a number connection test. Thus, the seventh-1 inspection process can include a process of performing a language number connection test on the user to calculate a seventh-1 inspection score.

[0068] The 7-2 inspection process can include a process of performing an inspection on a 7-2 inspection item that presents numbers and days of the week and evaluates how accurately and quickly the day of the week corresponding to the number is selected within the 7-2 time limit, and calculating a 7-2 inspection score. Here, the 7-2 inspection item can include a number-day connection inspection. Accordingly, the 7-2 inspection process can include a process of performing a pattern number-day connection inspection on a user and calculating a 7-2 inspection score.

[0069] Different from the conventional Trail Making Test, the Trail Making Test according to this embodiment was developed as a digital version of a Korean version of the Trail Making Test for the elderly, which was developed by replacing the alphabet with familiar days of the week (Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday) considering the characteristics of Korean elderly people.

[0070] The 8th inspection process can be executed after the execution of the 4-2 inspection process is completed. The 8th inspection process can perform an inspection on an 8th inspection item that evaluates whether to arrange the sizes of a given presentation object in descending or ascending order, and calculate an 8th inspection score. Here, the 8th inspection item can include a size-weight inspection.

[0071] The size-weight inspection can be a linguistic inspection that evaluates semantic memory by presenting three animals and three objects each and arranging each stimulus by size and weight. The size-weight inspection was developed into a Korean version modified to suit Korean elderly people for the stimuli of animals and objects, and its usability was evaluated for validity. As a result of the study, the inspection scores showed a significant difference between the normal group and Alzheimer's disease dementia (AD), and the two groups could be discriminated. Also, the inspection scores showed a significant difference between Alzheimer's disease dementia and semantic variant primary progressive aphasia (SV-PPA), and both clinical groups could be discriminated. A significant correlation was shown between the inspection scores and the volumes of gray matter in the right inferior frontal cortex and bilateral temporal cortices, which are brain regions involved in recalling semantic information from the results of brain imaging of SV-PPA patients.

[0072] In this embodiment, the eighth inspection process can include an eighth - 1 inspection process and an eighth - 2 inspection process.

[0073] The eighth - 1 inspection process can perform an inspection on an eighth - 1 inspection item that evaluates whether to arrange the sizes of predetermined presentation objects in descending or ascending order, and calculate an eighth - 1 inspection score. Here, the eighth - 1 inspection item can include a size inspection. Thus, the eighth - 1 inspection process can include a process of performing a size inspection on the user and calculating an eighth - 1 inspection score.

[0074] The eighth - 2 inspection process can perform an inspection on an eighth - 2 inspection item that evaluates whether to arrange the weights of predetermined presentation objects in descending or ascending order, and calculate an eighth - 2 inspection score. Here, the eighth - 2 inspection item can include a weight inspection. Thus, the eighth - 2 inspection process can include a process of performing a weight inspection on the user and calculating an eighth - 2 inspection score.

[0075] The differences between the size - weight inspection included in the eighth inspection process according to this embodiment and the conventional size - weight inspection can be as follows. The size - weight inspection according to this embodiment classifies objects according to size and objects according to weight into a plurality (for example, five) of categories respectively, and can configure the difficulty level as low / medium / high through the level - by - level classification between categories. Combinations between categories with large differences in weight and size may have a low difficulty level. Combinations between categories with small differences in weight and size may have a high difficulty level. Also, the beginning can be composed of simple questions and the latter half can be composed of difficult questions. The image of the object can be a picture composed of lines and can be configured so that the characteristics of the object (such as an animal, an object, etc.) are well represented. Also, objects that are not familiar to the elderly in Korea can be configured to be excluded.

[0076] The 9th inspection process can be executed after the execution of the 8th inspection process is completed. The 9th inspection process provides an arbitrary image and a narration for the arbitrary image, and executes an inspection for the 9th inspection item that evaluates the degree of understanding of the social situation based on the collection result of positive and negative responses to questions after the provision of the narration, and can include a process of calculating the 9th inspection score. Here, the 9th inspection item can include a theory of mind inspection. Thereby, the 9th inspection process can include a process of performing a theory of mind inspection on the user and calculating the 9th inspection score.

[0077] Social cognition is the ability to perceive, interpret, and process social information that is constantly encountered in daily life. The theory of mind means the ability to decode or infer mental states such as the beliefs, needs, and intentions of others, and enables one to understand others and predict their actions. The theory of mind inspection can be composed of a cognitive aspect and an emotional aspect. The theory of mind inspection can be configured to evaluate the understanding and coping ability with respect to social situations based on the theory of mind.

[0078] The differences between the theory of mind inspection included in the 9th inspection process according to this embodiment and the conventional picture arrangement test can be as follows. The conventional picture arrangement test (WAIS-R) is a test that arranges the given pictures in order to match the flow of the story and checks whether the social situation is understood. However, the conventional picture arrangement test is highly difficult for the elderly and difficult to perform. Therefore, the theory of mind inspection according to this embodiment can be composed of a test that modifies the story to content that is friendly to the elderly and understands the intentions of the characters and the social situation from the content presented for each scene and listens to the emotions of the characters.

[0079] The 10th inspection process can be executed after the execution of the 9th inspection process is completed. The 10th inspection process can include a process of performing an inspection on a 10th inspection item that evaluates whether to find a figure in a color different from the color of a default presentation figure, and calculating a 10th inspection score. Here, the 10th inspection item can include a color perception inspection. Accordingly, the 10th inspection process can include a process of performing a color perception inspection on a user and calculating a 10th inspection score.

[0080] The differences between the color perception inspection included in the 10th inspection process according to this embodiment and the conventional color perception inspection can be as follows. As the conventional color perception inspection, the Farnsworth Munsell 100 hue test divides similar colors into four color regions and arranges them based on three attributes of color: hue, chroma, and lightness. The user checks whether to distinguish the color difference by arranging the colors in the correct order with the colors at both ends as a reference. On the other hand, the color perception inspection according to this embodiment can be configured by selecting colors based on a color system of a green color series and a blue color series in consideration of the fact that Parkinson's disease dementia patients have difficulty in distinguishing between blue and green. The color perception inspection according to this embodiment can be configured such that instead of arranging the entire colors in the same way as the conventional inspection, two colors are selected, and the difficulty level is high when the color difference is small and the difficulty level is low when the color difference is large.

[0081] After the execution of the 1st inspection process to the 10th inspection process is completed, the inspection device 100 can execute a category classification process of classifying at least one inspection item among a plurality of inspection items into any one of a plurality of neurocognitive categories. In this embodiment, the category classification process can be expressed as a category classification step in the claims described later.

[0082] The inspection device 100 can classify the 2nd inspection item (verbal cue memory test) and the 4th inspection item (visual schematic memory test) into a 1st neurocognitive category that can evaluate the decline in cognitive function with respect to memory.

[0083] The inspection device 100 can be classified into a second neurocognitive category that can distinguish the sixth inspection item (facial emotion inspection) and the ninth inspection item (theory of mind inspection) for neurocognitive disorders related to social cognition.

[0084] The inspection device 100 can be classified into a third neurocognitive category that can evaluate the decline in cognitive function for language based on the eighth inspection item (size-weight inspection).

[0085] The inspection device 100 can be classified into a fourth neurocognitive category that can evaluate the decline in cognitive function for perception based on the tenth inspection item (color perception inspection).

[0086] The inspection device 100 can be classified into a fifth neurocognitive category that can evaluate the decline in cognitive function for attention and execution based on the first inspection item (fluency inspection), the third inspection item (symbol-digit matching inspection), the fifth inspection item (Stroop inspection), and the seventh inspection item (trail making inspection).

[0087] After the execution of the category classification process is completed, the inspection device 100 can execute an evaluation process to evaluate whether there is a decline in cognitive function in the neurocognitive category based on the inspection scores for the inspection items classified into the neurocognitive category. In this embodiment, the evaluation process can be expressed as an evaluation step in the claims described later.

[0088] The inspection device 100 can execute a first evaluation process to evaluate whether there is a decline in cognitive function for the first neurocognitive category as memory based on the second inspection score (language cue memory inspection score) and the fourth inspection score (visual pattern memory inspection score). "

[0089] The inspection device 100 can execute a second evaluation process to evaluate whether there is a decline in cognitive function for the second neurocognitive category as social cognition based on the sixth inspection score (facial emotion inspection score) and the ninth inspection score (theory of mind inspection score).

[0090] The inspection device 100 can execute a third evaluation process for evaluating whether there is a decline in cognitive function with respect to the third neurocognitive category as a language, based on the eighth inspection score (size and weight inspection score).

[0091] The inspection device 100 can execute a fourth evaluation process for evaluating whether there is a decline in cognitive function with respect to the fourth neurocognitive category as a perception, based on the tenth inspection score (color perception inspection score).

[0092] The inspection device 100 can execute a fifth evaluation process for evaluating whether there is a decline in cognitive function with respect to the fifth neurocognitive category as attention execution, based on the first inspection score (fluency inspection score), the third inspection score (symbol - digit matching inspection score), the fifth inspection score (Stroop inspection score), and the seventh inspection score (trail making inspection score).

[0093] In the present embodiment, the inspection device 100 can exist independently in a server form, or the inspection function for evaluating the decline in cognitive function provided by the inspection device 100 can be embodied in an application form and installed on the user terminal 200.

[0094] The user terminal 200 can access the inspection application for evaluating the decline in cognitive function provided by the inspection device 100 and / or the inspection site for evaluating the decline in cognitive function, and receive the inspection service for evaluating the decline in cognitive function. Here, the user terminal 200 can include the terminal equipped with the user who undergoes the inspection, that is, the subject.

[0095] Such a user terminal 200 can include a communication terminal capable of executing the functions of a computing device (not shown), and in addition to a desktop computer 201, a smartphone 202, and a notebook computer 203 operated by a user, it can be a tablet PC, a smart TV, a mobile phone, a PDA (personal digital assistant), a media player, a micro server, a GPS (global positioning system) device, an e-book terminal, a digital broadcast terminal, a navigation device, a kiosk, an MP3 player, a digital camera, a home appliance, and other mobile or non-mobile computing devices, but is not limited thereto. Further, the user terminal 200 can be a wearable terminal such as a watch, glasses, a hair band, and a ring having a communication function and a data processing function. Such a user terminal 200 is not limited to the above-described content, and any terminal capable of web browsing can be borrowed without limitation.

[0096] The network 300 can play a role in connecting the inspection device 100 and the user terminal 200. Such a network 300 can cover wired networks such as LAN (local area network), WAN (wide area network), MAN (metropolitan area network), ISDN (integrated service digital network), and wireless networks such as WLAN (wireless LAN), CDMA (code-division multiple access), and satellite communication. However, the scope of the present invention is not limited thereto. Further, the network 300 can transmit and receive information using short-distance communication and / or long-distance communication. Here, short-distance communication can include Bluetooth, RFID (radio frequency identification), IrDA (infrared data association), UWB (ultra-wideband), ZigBee, and Wi-Fi technology, and long-distance communication can include CDMA (code-division multiple access), FDMA (frequency-division multiple access), TDMA (time-division multiple access), OFDMA (orthogonal frequency-division multiple access), and SC-FDMA (single carrier frequency-division multiple access) technology.

[0097] The network 300 can include connections of network elements such as hubs, bridges, routers, and switches. The network 300 can include one or more connected networks, such as a public network such as the Internet and a private network such as a secure enterprise private network, for example, multiple network environments. Access to the network 300 can be provided via one or more wired or wireless access networks.

[0098] Furthermore, the network 300 can support CAN (controller area network) communication, V2I (vehicle to infrastructure) communication, V2X (vehicle to everything) communication, Wave (wireless access in vehicular environment) communication technology, and an IoT (Internet of Things) network and / or 5G communication that exchanges and processes information between distributed components such as things.

[0099] FIG. 2 is a block diagram showing a configuration of an inspection apparatus for evaluating cognitive function decline according to the present embodiment for a schematic explanation. In the following description, parts overlapping with the description of FIG. 1 are omitted. Referring to FIG. 2, the inspection apparatus 100 can include a communication unit 110, a storage medium 120, a program storage unit 130, a database 140, an inspection management unit 150, and a control unit 160.

[0100] The communication unit 110 can provide a communication interface necessary to provide transmission and reception signals between the inspection apparatus 100 and the user terminal 200 in the form of packet data in conjunction with the network 300. Furthermore, the communication unit 110 can play a role of transmitting the request information of the inspection management unit 150 to the user terminal 200 and receiving the response information of the user terminal 200. Here, the communication network is a medium that plays a role of connecting the inspection apparatus 100 and the user terminal 200, and can include a connection path that provides a connection path so that information can be transmitted and received after the user terminal 200 is connected to the inspection apparatus 100. Also, the communication unit 110 can be a device including hardware and software necessary to transmit and receive signals such as control signals or data signals through a wired or wireless connection with other network devices.

[0101] The memory medium 120 executes a function of temporarily or permanently storing data processed by the control unit 160. Here, the memory medium 120 can include a magnetic storage media or a flash storage media, but the scope of the present invention is not limited thereto. Such a memory medium 120 can include a built-in memory and / or an external memory, such as a volatile memory like DRAM, SRAM, or SDRAM, a non-volatile memory like OTPROM (one time programmable ROM), PROM, EPROM, EEPROM, maskROM, flashROM, NAND flash memory, or NOR flash memory, a flash drive like SSD, CF (compact flash) card, SD card, Micro-SD card, Mini-SD card, Xd card, or memory stick, or a storage device like HDD.

[0102] The program storage unit 130 is equipped with control software that performs operations such as an inspection process of inspecting to what extent missions presented for each of a plurality of inspection items are completed for a user and calculating inspection scores for each of the plurality of inspection items, a category classification process of classifying at least one inspection item among the plurality of inspection items into any one of a plurality of neurocognitive categories, and an evaluation process of evaluating whether there is a decline in cognitive function in the neurocognitive category based on the inspection scores for the inspection items classified into the neurocognitive category.

[0103] The database 140 can include a management database that stores inspection information for evaluating cognitive decline. For example, the management database can store information related to the first to tenth inspection processes, information related to the first to fifth neurocognitive category classification processes, information related to the first to fifth evaluation processes, information related to the process of evaluating Alzheimer's disease dementia, information related to the process of evaluating frontotemporal dementia, and information related to the process of evaluating Parkinson's disease dementia and Lewy body dementia.

[0104] In addition, the management database can store the correct answers corresponding to the instruction texts described later. For example, the management database can store the correct answer text corresponding to the first instruction text, the correct answer word or picture corresponding to the 2-1 instruction text, the correct answer word or picture corresponding to the 2-2 instruction text, the correct answer corresponding to the third instruction text, the correct answers corresponding to the 4-1 and 4-2 instruction texts, the correct answers corresponding to the 5-1 and 5-2 instruction texts, the correct answer corresponding to the sixth instruction text, the correct answers corresponding to the 7-1 and 7-2 instruction texts, the correct answers corresponding to the 8-1 and 8-2 instruction texts, the correct answer corresponding to the ninth instruction text, and the correct answer corresponding to the tenth instruction text.

[0105] In addition, the management database can store the method for calculating the inspection score. In the present embodiment, a series of inputs received from the user terminal 200 corresponding to the instruction text are compared with the correct answers, and the number of incorrect answers to the overall correct answers can be counted to calculate the inspection score. Here, the more the number of incorrect answers, the lower the inspection score may be, and the fewer the number of incorrect answers, the higher the inspection score may be.

[0106] In the present embodiment, the inspection score can be changed according to the count result of the required time described later. For example, when the count result of the required time exceeds the limit time, the inspection score can be further lowered.

[0107] In addition, the management database can store reference scores for evaluating cognitive function decline. The calculation process of the reference scores can be described as follows.

[0108] In the first process, the first to tenth examination processes can be executed for the normal group. Here, the normal group is a group of healthy individuals without cognitive function decline, and can be classified differently according to gender / education level / age. As a result of executing the first to tenth examination processes for the normal group, the first to tenth examination scores of the normal group can be calculated.

[0109] In the second process, for the first to tenth examination scores of the normal group, the first to tenth average values and the first to tenth standard deviations can be calculated.

[0110] In the third process, at least one of the first to tenth examination items for the normal group can be classified into any one of the first to fifth neurocognitive categories. The second and fourth examination items for the normal group are classified into the first neurocognitive category, the sixth and ninth examination items for the normal group are classified into the second neurocognitive category, the eighth examination item for the normal group is classified into the third neurocognitive category, the tenth examination item for the normal group is classified into the fourth neurocognitive category, and the first, third, fifth, and seventh examination items for the normal group can be classified into the fifth neurocognitive category.

[0111] In the fourth process, the first to tenth Z-scores can be calculated using the first to tenth average values and the first to tenth standard deviations for the first to tenth examination scores. Here, it can be said that the Z-score is a score that indicates how far the examination score is from the average value when the standard deviation is used as the unit.

[0112] In this embodiment, when the Z-score is less than or equal to the first standard deviation (e.g., -1.5SD), it is possible to evaluate that there is a decline in cognitive function in the neurocognitive category to which the test item belongs. Thus, the reference score can be said to be the test score of the normal group where the Z-score is the first standard deviation (e.g., -1.5SD). In this embodiment, the reference score can include the first to tenth reference scores. In this embodiment, the Z-score can also include the first to tenth Z-scores.

[0113] As an alternative embodiment, the reference score can be expressed as a standard cut-off score. Here, the standard cut-off score can be said to be the test score of the normal group where the above-mentioned Z-score is the first standard deviation (e.g., -1.5SD). In this embodiment, the standard cut-off score can include the first to tenth standard cut-off scores.

[0114] In this embodiment, the reference score can be updated periodically. Each time the user executes a test application for evaluating cognitive decline via the user terminal 200 or accesses a test site for evaluating cognitive decline in order to perform a test for evaluating cognitive decline, the reference score can be updated in real time.

[0115] Conventionally, in order to calculate the reference score, a large number of personnel and time were required in the process of conducting tests on a large number of subjects and collecting the resulting scores. Even when new results were generated, it took a long time for the new results to be reflected in the reference score.

[0116] On the other hand, in this embodiment, the test results collected in real time are stored in the database 140, and the reference score is updated immediately, so that the latest reference score can always be maintained. Through this real-time update of the reference score, it can be helpful for the user to always diagnose the cognitive state based on the accurate reference score. Also, since the test process is carried out online, it is possible to assist in the diagnosis based on the latest reference score without restrictions on the test location and time.

[0117] In addition, the database 140 can include a user database that stores information of users who are provided with inspection services for evaluating cognitive function decline. Here, the user information includes unique information about the user, such as the user's name, affiliation, identity details, gender, age, education level, contact information, email, address, image, etc., and information related to user authentication (login), such as an ID (or email) and password, information related to the connection country, connection location, information about the device used for connection, and information related to the connection, such as the connected network environment.

[0118] In addition, the user database can store the user's information, information provided by users who accessed an inspection application for evaluating cognitive function decline or an inspection site for evaluating cognitive function decline and / or category history, environment setting information set by the user, resource usage amount information used by the user, and charging and settlement information corresponding to the user's resource usage amount.

[0119] The inspection management unit 150 can execute an inspection process that inspects to what extent missions presented for each of a plurality of inspection items for a user are completed and calculates inspection scores for each of the plurality of inspection items.

[0120] After the execution of the inspection process is completed, the inspection management unit 150 can execute a category classification process that classifies at least one of the plurality of inspection items into any one of a plurality of neurocognitive categories.

[0121] After the execution of the category classification process is completed, the inspection management unit 150 can execute an evaluation process that evaluates whether there is a decline in cognitive function in the neurocognitive category based on the inspection scores for the inspection items classified into the neurocognitive category.

[0122] After the execution of the evaluation process is completed, the inspection management unit 150 can transmit the evaluation results to the user terminal 200 and / or the terminal of the medical practitioner (e.g., a doctor) (not shown).

[0123] The control unit 160 can control the operation of the entire inspection device 100 by using control software installed in the program storage unit 130 as a kind of central processing unit. The control unit 160 can include any type of device capable of processing data, such as a processor. Here, the "processor" can mean, for example, a data processing device incorporated in hardware that has a physically structured circuit for executing functions represented by codes or instruction words included in a program. As an example of such a data processing device incorporated in hardware, it is possible to cover processing devices such as a microprocessor, a central processing unit (CPU), a processor core, a multiprocessor, an ASIC (application-specific integrated circuit), and an FPGA (field programmable gate array), but the scope of the present invention is not limited thereto.

Referring to FIG. 4, the first screen can include an icon and text representing the test. As one embodiment, the providing unit 151 can provide an icon and text (the first test) representing the first test to the user terminal 200 for the first test process. Here, the first test represented by the text is a summary of the first test process and can be provided in a simple and clear manner considering the elderly. In such a way, the providing unit 151 can provide an icon and text representing the second test to the tenth test to the user terminal 200 for the second test process to the tenth test process.

[0127] The data processed by the first processing unit 152 to the third processing unit 154 can be provided to the user terminal 200 by the providing unit 151. In particular, a series of data provided by the first processing unit 152 is originally provided by the providing unit 151, but for the sake of convenience of explanation, it will be described assuming that it is provided by the first processing unit 152.

[0128] The first processing unit 152 can execute the first test process. In the present embodiment, the first processing unit 152 can execute the first test process excluding the practice test a plurality of times.

In the present embodiment, the progress bar 504 can execute one or more of a function of counting the limited time and a function of indicating the progress of the work.

[0138] FIG. 5D shows a screen for notifying the re - execution of the first practice inspection process. If the user has not input the microphone button 503, the number of spoken words is less than a predetermined number (for example, 3), or the speaking volume is low, the first practice inspection process can be re - executed.

[0139] FIG. 5E shows a screen indicating that the execution of the first practice inspection process is completed and notifying the execution of this inspection.

[0140] FIG. 5F shows a screen for notifying the start of the first instructions and the first inspection process. When the start button 505 is input, the screen can be switched to the next screen.

[0141] FIG. 5G shows a screen for executing the first inspection process. After the user checks the first instructions, the user can input the microphone button 506 and speak words corresponding to the first instructions while looking at the progress bar 507.

[0142] Returning to FIG. 3, the first processing unit 152 can execute a second inspection process including a second - 1 inspection process and a second - 2 inspection process. In the present embodiment, the first processing unit 152 can execute the second inspection process a plurality of times.

[0143] When executing the second - 1 inspection process, the first processing unit 152 can provide the user terminal 200 with a second - 1 instruction that shows a plurality of presented words or a plurality of presented pictures and allows the user to select a word or a picture corresponding to a clue of a predetermined category among the plurality of presented words or the plurality of presented pictures.

[0144] The first processing unit 152 can receive the selection result of one word or picture selected from among a plurality of presented words or presented pictures corresponding to the second-1 instruction sentence from the user terminal 200.

[0183] The first processing unit 152 can count the first required time from the time when the fourth - 2 instruction text is provided to the time when it is selected whether the predetermined second image is the same as the predetermined first presentation image shown previously.

[0184] The first processing unit 152 can calculate the fourth - 2 inspection score by reflecting the result of the comparison and the result of counting the first required time. In this embodiment, the fourth - 2 inspection score can be calculated to be different according to the total number of times the fourth - 2 inspection process is executed, the selection result determined to be correct, and the result of counting the first required time. Even if the number of selection results determined to be correct is large for the total number of times the fourth - 2 inspection process is executed, if the result of counting the first required time is large, the fourth - 2 inspection score can be low. Also, even if the number of selection results determined to be correct is small for the total number of times the fourth - 2 inspection process is executed, if the result of counting the first required time is small, the fourth - 2 inspection score can be high.

[0185] In this embodiment, before executing the fourth - 2 inspection process, the first processing unit 152 can provide the user terminal 200 with one or more of the execution method of the fourth - 2 inspection process in text and an explanation display screen.

[0186] As an alternative embodiment, the first processing unit 152 can calculate the fourth inspection score by summing the fourth-1 inspection score and the fourth-2 inspection score. Further, the first processing unit 152 can use each of the fourth-1 inspection score and the fourth-2 inspection score without summing them when evaluating cognitive function decline. In this embodiment, when the fourth inspection score is higher than the cut-off score of the fourth standard, it can be evaluated that the visual perception memory is good, and when the fourth inspection score is lower than the cut-off score of the fourth standard, it can be evaluated that the visual perception memory has declined.

[0233] Returning to FIG. 3, the first processing unit 152 can execute a seventh inspection process including a seventh - 1 inspection process and a seventh - 2 inspection process. In this embodiment, the first processing unit 152 can execute the seventh - 1 inspection process and the seventh - 2 inspection process (excluding the practice inspection) multiple times.

[0234] When the first processing unit 152 executes the seventh - 1 inspection process, it can provide the user terminal 200 with a seventh - 1 instruction text for selecting any number started and displayed within the seventh - 1 time limit (for example, 300 seconds) and selecting the other presented numbers in descending or ascending order.

[0235] The first processing unit 152 can receive the result of selecting any number started and displayed corresponding to the seventh - 1 instruction text from the user terminal 200 and selecting the other presented numbers in descending or ascending order.

[0236] The first processing unit 152 can count the time elapsed until the result of selecting numbers in descending or ascending order becomes correct, and calculate the 7-1 inspection score. That is, the time taken to complete the task without error within the 7-1 time limit can be calculated as the 7-1 score. The shorter the time taken to complete the task without error, the better the execution function can be evaluated. Also, if there are 5 mistakes within the 7-1 time limit, it can be considered that the 7-1 inspection has failed.

[0237] In the present embodiment, before executing the 7-1 inspection process, the first processing unit 152 can provide the user terminal 200 with the execution method of the 7-1 inspection process in one or more of text and an explanation display screen, and can cause the user terminal 200 to execute a practice inspection for the 7-1 inspection process.

[0238] After the execution of the 7-1 inspection process is completed and a predetermined time has elapsed, the first processing unit 152 can execute the 7-1 inspection process.

[0239] When executing the 7-2 inspection process, the first processing unit 152 can provide the user terminal 200 with a 7-2 instruction sentence that causes the user to alternately select an arbitrary number and the day of the week corresponding to the arbitrary number from among the numbers and days of the week presented within the 7-2 time limit.

[0240] The first processing unit 152 can receive the result of alternately selecting an arbitrary number and the day of the week corresponding to the arbitrary number in response to the 7-2 instruction sentence from the user terminal 200.

[0241] The first processing unit 152 can count the time elapsed until the result of selecting numbers in descending or ascending order becomes correct, and calculate the 7-2 inspection score. That is, the time taken to complete the task without error within the 7-2 time limit can be calculated as the 7-2 score. The shorter the time taken to complete the task without error, the better the execution function can be evaluated. Also, if there are 5 mistakes within the 7-2 time limit, it can be considered that the 7-2 inspection has failed.

[0242] In this embodiment, before executing the 7-2 inspection process, the first processing unit 152 can provide the user terminal 200 with the method of executing the 7-2 inspection process in one or more of text and an explanation display screen, and can cause the user terminal 200 to execute a practice inspection for the 7-2 inspection process.

[0243] As an alternative embodiment, the first processing unit 152 can calculate the 7-1 inspection score and the 7-2 inspection score together to obtain the 7 inspection score. Also, the first processing unit 152 can use each of the 7-1 inspection score and the 7-2 inspection score separately when evaluating the execution function without summing them up. In this embodiment, when the sum of the 7-1 inspection score and the 7-2 inspection score is higher than the cut-off score of the 7th standard, it can be evaluated that the execution function is better, and when the 7 inspection score is lower than the cut-off score of the 7th standard, it can be evaluated that the execution function has deteriorated.
