Embodiment 1

[0045] refer to Figure 1 to Figure 5 , a computer-aided screening device for mild cognitive impairment (MCI) in the elderly, the device includes an MCI test server 1 and an examination client 2, the MCI test server 1 includes: a personal information memory unit 3, used To save the tester's personal basic information and test results; the scale memory unit 4 is used to provide the test scale for objectively judging MCI for the MCI test check client, and the test scale includes orientation test questions, memory test questions, attention and vigilance test questions, calculation test questions, language naming test questions, delayed recall test questions, word fluency test questions, graphic recognition test questions, verbal comprehension test questions, abstract ability test questions and visual structure skill test questions; The table sending unit 5 is used to send the MCI test scale to the MCI inspection client computer; the answer receiving unit 6 is used to receive the ...

Embodiment 2

[0114] refer to figure 1 , figure 2 , Figure 6 , in some places where the server and the client cannot be configured to communicate and interact, the MCI diagnosis can also be carried out in a stand-alone mode, and the MCI degree judgment standard and test scale can be downloaded from the server. The whole process is the same as in embodiment 1, as shown in Figure 4 As shown, the explanations about the results of the MCI screening are omitted here because they have been explained above.

Embodiment 3

[0116] refer to figure 1 , figure 2 , Figure 7 , for some places where there is no computer, you can use paper to test and then use OCR to read the test results. The whole process is as follows Figure 5 shown. The tester first writes the questions answered on the pre-made answer sheet, and then reads it into the computer through the OCR reading device 18 to determine the MCI degree. The whole determination process is the same as in Example 1, and the results are as shown in Table 1. Explanation of Screening Result Since it has been explained above, these explanations are omitted here, and the result of MCI degree judgment is printed out by the result printing unit 19 as a test result report.

Abstract

The invention relates to a computer-aided device for screening mild cognitive impairment (MCI) of old people. The device comprises an MCI test server and an inspection client, wherein the MCI test server comprises a personal information memorizing unit, a scale memorizing unit for supplying a test scale for objectively judging the MCI to the MCI test inspection client, a scale sending unit, a response receiving unit, an MCI degree counting and memorizing unit, an MCI identifying and comparing unit and a result sending unit; and the inspection client comprises a basic information entering unit, a basic information sending unit, a scale receiving unit, a scale expressing unit, a response acquiring unit, a response sending unit, a result receiving unit and a result displaying unit. The test paper of the test scale comprises orientation force, memory, notice, watchfulness, calculation power, language denomination, delayed recall, verbal fluency, pattern recognition, verbal understanding, abstract ability and visual structure skill. The invention has the advantages of definite reliability and validity and good reliability, and is simple in operation and convenient in general survey.

Description

technical field [0001] The invention belongs to the application of computer technology, network technology and communication technology in the diagnosis of mild cognitive impairment (MCI) in the elderly, and is applicable to rehabilitation centers, hospitals, nursing homes, communities and families, and is used for superseding senile dementia. Early screening and auxiliary diagnosis. Background technique [0002] Senile dementia (Alzheimer's Disease, AD) is a group of diseases with unknown etiology. The main symptom is the overall decline in intelligence, leading to the loss of living ability. It is one of the important diseases that cause disability in the elderly. According to the survey, the prevalence rate of senile dementia in my country is 6.9% in the northern region over 65 years old, and 3.9% in the southern region; there are about 1.8 million new patients and 1.056 million deaths every year, and it is estimated that there are about 20 million patients in my country....
