Description

Technical Field

[0001] The invention relates to a subjective risk assessment system for memory loss. Background Art

[0002] Memory complaints (MC) can be a manifestation of aging due to age-related and physiological memory loss, or it can be one of the early symptoms of cognitive impairment or dementia. Elderly people often go to the hospital for treatment due to memory loss. Some are diagnosed with normal aging, some are diagnosed with mild cognitive impairment, and some are diagnosed with dementia such as Alzheimer's disease. How to discover risk indicators for predicting early symptoms of dementia from subjective complaints of memory loss is of great significance for disease prevention and clinical diagnosis and treatment.

[0003] In the current assessment of subjective risk of memory loss, self-assessment is mostly used, with item-based questions and two-choice answers of yes or no. Some will further assess the frequency and severity of symptoms. Some symptoms occur frequently, although the degree of occurrence is very mild; some symptoms occur very severely, but the frequency of occurrence is very low. How to weigh the relationship between the degree and frequency of symptoms? How to organically combine the frequency and severity of symptoms? This is a question that everyone is interested in, but there is no good solution. We found that as a subjective self-assessment, the finer the degree of division, the higher the ambiguity and vacillation between different options, which will affect the accuracy of the assessment results. In addition, when the elderly have related problems, their families will take corresponding remedial or intervention measures to reduce or avoid the elderly from engaging in related activities, which leads to the frequency and severity assessment of related symptoms not accurately reflecting the actual situation of the elderly. For example, if an elderly person has been lost once and is no longer allowed to go out alone, the frequency and risk of getting lost will be significantly reduced. However, the ability to predict the risk of cognitive impairment will not decrease just because the person no longer gets lost. The risks and concerns will not be eliminated just because the person no longer gets lost, and sometimes will increase instead.

[0004] During the clinical diagnosis and treatment process, we also found that the fundamental reason why the elderly reduce or avoid related activities is that their families are not confident in their abilities and are worried about danger. Faced with the complaints or complaints of memory loss in the elderly, there are obvious differences in the degree of concern about these symptoms by the elderly themselves, especially their families. This concern precisely reflects the overall changes in the elderly's cognitive function, personality behavior, daily living ability, etc. due to memory loss, as well as the comprehensive impact of the elderly's usual knowledge and cultural level, principles of dealing with people, family assistance, and psychological support on these symptoms. Summary of the invention

[0005] The present invention provides a subjective risk assessment system for memory loss, which adopts the following technical solutions:

[0006] A subjective risk assessment system for memory loss, comprising:

[0007] A first information setting module is used to set the patient's identity information;

[0008] The second information setting module is used to set the identity of the evaluator;

[0009] An evaluation module, used for receiving evaluation information of a patient input by an evaluator;

[0010] A calculation module is used to analyze and calculate the evaluation information input by the evaluator to obtain the evaluation score;

[0011] The risk module is used to evaluate the patient's risk level based on the evaluation score calculated by the calculation module.

[0012] Furthermore, the evaluation module includes:

[0013] An information storage submodule, used to store a number of evaluation questions;

[0014] The evaluation submodule is used to receive evaluation information from the evaluator regarding a number of evaluation questions.

[0015] Further, the evaluation information of the evaluator on the evaluation question received by the evaluation submodule includes first information;

[0016] The first information includes three levels. The first level indicates that the evaluator's judgment result on the assessment question is yes, the second level indicates that the evaluator's judgment result on the assessment question is no, and the third level indicates that the evaluator's judgment result on the assessment question is uncertain. The evaluator evaluates each assessment question based on the patient's actual situation.

[0017] Furthermore, the evaluation information of the evaluator on the evaluation question received by the evaluation submodule further includes second information;

[0018] When the evaluator's evaluation result for a certain evaluation question is the first level, the evaluator further evaluates the second information for this evaluation question;

[0019] The second information includes three levels. The first level indicates that the evaluator is not worried about the condition corresponding to the assessment problem of the patient, the second level indicates that the evaluator is somewhat worried about the condition corresponding to the assessment problem of the patient, and the third level indicates that the evaluator is very worried about the condition corresponding to the assessment problem of the patient.

[0020] Further, the evaluation score includes: abnormal frequency N1, first weighted frequency Y1, second weighted frequency Y2, third weighted frequency Y3 and weighted total score Z;

[0021] The abnormal frequency N1 is the frequency of the evaluation result of the first information being the first level;

[0022] The first weighted frequency Y1 is the frequency of the evaluation result of the second information being the first level;

[0023] The second weighted frequency Y2 is the frequency of the evaluation result of the second information being the second level;

[0024] The third weighted frequency Y3 is the frequency of the evaluation result of the second information being the third level;

[0025] The weighted total score Z is the sum of the scores corresponding to the evaluation results in the second information.

[0026] Furthermore, the specific method for the risk module to evaluate the patient's risk level according to the evaluation score calculated by the calculation module is:

[0027] Determine the patient's initial risk level based on the abnormal frequency N1;

[0028] The preliminary risk level is modified according to the first weighted frequency Y1, the second weighted frequency Y2, the third weighted frequency Y3 and the weighted total score Z to obtain the final risk level.

[0029] Furthermore, 10 evaluation questions are stored in the information storage submodule.

[0030] Furthermore, the evaluation module includes:

[0031] The setting submodule is used to set the evaluation questions in the information storage submodule.

[0035] The report generation module is used to generate an assessment report for the patient based on the assessment information input by the assessor, the assessment score calculated by the calculation module and the risk level assessed by the risk module.

[0036] The benefit of the present invention is that the subjective risk assessment system for memory loss provided can discover risk indicators for predicting early symptoms of dementia from the subjective complaints of memory loss, which has very important significance for disease prevention and clinical diagnosis and treatment. The subjective risk assessment system for memory loss can be applied to non-professionals, especially family self-assessment, thereby pushing the risk assessment of dementia-related memory loss to the pre-hospital stage, reducing the time and labor cost pressure of in-hospital examinations. At the same time, the subjective risk assessment system for memory loss can also enhance the public's understanding and popularization of knowledge about memory loss and dementia through assessment items such as assessment questions and assessment scores, improve the ability to recognize and identify early symptoms of dementia, and promote early identification and early detection of dementia.

[0037] The present invention is also beneficial in that the provided subjective risk assessment system for memory loss takes into account the assessor's degree of concern about different symptoms in the risk level determination as an important basis for risk level determination, making the assessment result more accurate.

DETAILED DESCRIPTION

[0040] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] like Figure 1 The present invention shows a subjective risk assessment system 10 for memory loss, comprising: a first information setting module 11, a second information setting module 12, an assessment module 13, a calculation module 14 and a risk module 15. Among them: the first information setting module 11 is used to set the patient's identity information. The second information setting module 12 is used to set the identity of the assessor. The assessment module 13 is used to receive the assessment information of the patient input by the assessor. The calculation module 14 is used to analyze and calculate the assessment information input by the assessor to obtain the assessment score. The risk module 15 is used to assess the patient's risk level according to the assessment score calculated by the calculation module 14. The patient's identity information here includes: gender, age, education, nationality, height, weight, region, whether there is obvious memory loss, whether there is a family history of dementia, etc. The identity of the assessor here includes: spouse, children, nanny, medical staff, community staff, elderly care service personnel, other personnel or the person himself.

[0042] As a preferred embodiment, the evaluation module 13 includes: an information storage submodule 131 and an evaluation submodule 132. The information storage submodule 131 is used to store a number of evaluation questions. The evaluation submodule 132 is used to receive evaluation information of the evaluator for a number of evaluation questions.

[0043] In the present invention, 10 evaluation questions are stored in the information storage submodule 131. Specifically, the questions are as follows:

[0044] Q1: Is there any difficulty in judgment? This question is used to judge the patient's complex thinking, judgment, organization and other executive functions. It can be manifested in work, housework, finance, interpersonal communication and other aspects, such as the ability to plan, divide labor, execute, and arrange personnel for work; the ability and level of planning family holiday gatherings and preparing banquets and meals have declined; the appearance of speech and behavior, etiquette and gifts that are not in line with one's own or the other party's identity; speech and behavior, clothing and dressing that are not in line with the social environment and seasons. Doing things becomes hesitant, thinking is difficult, lacks logic, or low-level financial or judgment decision-making errors, etc.; the ability to deal with home emergencies is reduced, such as water pipe leaks, garbage fires, etc.

[0045] Q2: Has the interest in hobbies, social or family activities decreased? This question is used to judge the patient's social activity ability and spontaneous internal motivation. For example, the elderly usually like to go out to chat and play chess, but recently they always stay alone, do not go out, and do not like to play chess. Even if they participate in activities, they are unwilling to talk and communicate; they used to be the boss inside and outside, but now they have become lazy and even need to be supervised to take a bath.

[0046] Q3: Do you repeat the same thing over and over again? This question is used to judge the patient's recall memory and stereotyped repetitive or paranoid behavior. For example, always repeating the questions, words, stories or things that have just been asked. For example, constantly asking what day it is, repeatedly saying that you have a bad heart, that falling when you were a child affected your memory, or even brushing your teeth and washing your feet many times before going to bed.

[0047] Q4: Is there any difficulty in learning to use tools, etc. This question is used to judge the patient's learning, operation and application ability. For example, it is difficult to learn to use newly purchased household appliances or tools (for example: new mobile phones, computers, microwave ovens, remote controls, etc.). Unlike before, you can use them quickly, and it takes more time to get familiar with them, which is inefficient and prone to errors. And the tools or repairs that you are familiar with have become unfamiliar, such as not being able to take pictures with a mobile phone, not being able to use a vacuum cleaner, not being able to sew, etc. .

[0048] Q5: Do you forget the correct month and year? This question is used to judge the patient's time orientation, memory, and analytical judgment abilities. For example, even days with obvious seasonal characteristics, festivals that have just passed or are about to pass, and even birthdays and other anniversaries may be forgotten.

[0049] Q6: Do you have difficulty dealing with complex financial issues? This question is used to assess the patient's judgment and calculation ability. For example, when you encounter weddings, funerals, or buying a house or a car, you cannot arrange your finances properly, forget how to pay for water, electricity, heating, medical insurance, social security, etc., or overpay for some non-essential expenses.

[0050] Q7: Do you have difficulty remembering appointments or times with others? This question is used to determine the patient's memory retrieval function and prospective memory. For example, family and friends call to inform you, agreed times and things are forgotten in a blink of an eye, and important things sometimes need to be reminded or written down in a notebook.

[0051] Q8: Do you have problems with thinking and / or memory every day? This question is used to judge the flexibility of the patient's memory and thinking. For example, you are always forgetful and flustered, you are not as efficient as before, it takes more time, your efficiency is low, you can't do two things at the same time, and you can't do several things at the same time.

[0052] Q9: Is there any obstacle in language expression and comprehension? This question is used to judge the patient's language and memory function. For example, when speaking, sometimes the words are not expressive, it is difficult to find words, there are errors in speech, and even knowing that it is a familiar person or thing, but can't say the name. In serious cases, time, place, and people are confused, and sometimes they can't understand what others say, and don't understand the meaning of some words, such as asking an old man to hold chopsticks, but not understanding what chopsticks are.

[0053] Q10: Have the personality and behavior changed? This question is used to judge the personality and behavior of the patient. For example, emotional indifference, becoming uncaring about others, or even very self-centered; becoming depressed and unhappy, or anxious and fearful, feeling insecure, and often checking doors, windows, and curtains at night; being unable to calm down, becoming irritable and impulsive, often getting angry over trivial matters, even pushing or scolding others, and suspecting that others have taken their belongings.

[0054] The evaluation information of the evaluator on the evaluation question received by the evaluation submodule 132 includes first information. The first information includes three levels, the first level indicates that the evaluator's judgment result on the evaluation question is yes, the second level indicates that the evaluator's judgment result on the evaluation question is no, and the third level indicates that the evaluator's judgment result on the evaluation question is uncertain. The evaluator evaluates each evaluation question according to the actual situation of the patient.

[0055] As a more preferred embodiment, the assessment information of the assessor on the assessment question received by the assessment submodule 132 also includes second information. When the assessor's assessment result on a certain assessment question is the first level, the second information is also evaluated for this assessment question. The second information includes three levels, the first level indicates that the assessor is not worried about the condition corresponding to the assessment question of the patient, the second level indicates that the assessor is somewhat worried about the condition corresponding to the assessment question of the patient, and the third level indicates that the assessor is very worried about the condition corresponding to the assessment question of the patient.

[0056] As a preferred embodiment, the evaluation module 13 includes: a setting submodule 151. The setting submodule 151 is used to set the evaluation questions in the information storage submodule 131. It can be understood that the number of the above questions and the setting of specific questions can be adjusted according to actual conditions.

[0057] As a specific weighting method, the evaluation score is set to include: abnormal frequency N1, first weighted frequency Y1, second weighted frequency Y2, third weighted frequency Y3 and weighted total score Z. Abnormal frequency N1 is the frequency of the evaluation result of the first level in the first information. The first weighted frequency Y1 is the frequency of the evaluation result of the first level in the second information. The second weighted frequency Y2 is the frequency of the evaluation result of the second level in the second information. The third weighted frequency Y3 is the frequency of the evaluation result of the third level in the second information. The weighted total score Z is the sum of the scores corresponding to the evaluation results in the second information. Specifically, the score corresponding to the first level is 1, the score corresponding to the second level is 2, and the score corresponding to the third level is 3.

[0058] Based on the above weighting method, the specific method for the risk module 15 to evaluate the patient's risk level according to the evaluation score calculated by the calculation module 14 is: determine the patient's preliminary risk level according to the abnormal frequency N1. The preliminary risk level is corrected according to the first weighted frequency Y1, the second weighted frequency Y2, the third weighted frequency Y3 and the weighted total score Z to obtain the final risk level. In other words, according to the frequency of N1, the risk stratification (MC risk stratification) of cognitive impairment is divided. Optionally, the risk is low (N1 = 0, 1), medium (N1 = 2, 3), high (N1 = 4, 5), and very high (N1 ≥ 6). According to the worry weighted frequency Y1, Y2, Y3 and the weighted total score Z value, the above MC risk stratification is weighted (MC + risk weighting): if Y2 ≥ 2, or Y3 ≥ 1, or Z ≥ 5, the risk stratification of cognitive impairment is adjusted from the original "low risk, medium risk, high risk" to "medium risk, high risk, very high risk" by one level.

[0059] In the present application, the assessor's degree of concern about these symptoms is taken into account in the risk level determination as an important basis for risk level determination, thereby improving the accuracy of the assessment results.

[0060] For example, in this embodiment, assume that Q2, Q4, and Q8 have changed, Q9 is unknown, and the other 6 items are normal. Then the abnormal frequency N1 is 3, and its corresponding risk level is medium. The first weighted frequency Y1 is 1, the second weighted frequency Y2 is 2, the third weighted frequency Y3 is 0, and Z is 1+2×2+3×0, which is 5. Since Y2 is 2 and Z is 5, the risk level is adjusted up one level from medium to high.

[0061] As a specific implementation, the memory impairment subjective risk assessment system 10 further includes: an early warning module 16 .

[0062] Specifically, the early warning module 16 warns the assessor when the risk level assessed by the risk module 15 reaches a preset level. For example, in this embodiment, the preset level is set to be high, and when the assessment result is high, the early warning module 16 issues a warning message, prompting the assessor to send the patient to the hospital for a comprehensive test.

[0063] As a specific implementation, the memory impairment subjective risk assessment system 10 further includes: a report generation module 17 .

[0064] The report generation module 17 is used to generate an assessment report for the patient based on the assessment information input by the assessor, the assessment score calculated by the calculation module 14, and the risk level assessed by the risk module 15. Specifically, the report generation module 17 comprehensively generates an assessment report based on the above-mentioned assessment information, so that the assessor can have a more comprehensive understanding of the patient's condition.

[0065] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present invention.
