Adaptive cognitive function assessment method and system

Abstract

The invention discloses an adaptive cognitive function assessment method and system. The cognitive function data of the respondent are acquired and a basic database is established; the characteristicparameters of a single cognitive test are analyzed based on the basic database and a cognitive assessment item question bank is constructed; the current cognitive ability value and the information quantity are further calculated in real time based on the question bank and the characteristic parameters according to the answer situation of the completed items of the testee; and the items most suitable for the ability of the testee are automatically selected for testing until the cognitive ability of the testee is accurately assessed. According to the method, adaptive computerized cognitive impairment screening and assessment can be realized so that the method can be applied to community organization and home testing; and adaptive testing varies from person to person so that the cognitive function level and the degree of cognitive impairment can be rapidly, objectively and accurately assessed.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to an adaptive cognitive function evaluation method and system. Background technique [0002] Cognitive impairment screening and functional assessment are key methods to assist in the diagnosis of Alzheimer's. At present, the methods widely used at home and abroad are as follows: [0003] 1. The paper-pen method is mainly used for face-to-face evaluation by professional evaluators and subjects. The test site is limited to medical institutions, and the completion of the test depends on trained professionals; [0004] 2. The grassroots medical staff lack the skills of how to select and operate the scale; [0005] 3. The judgment of the results depends on standardized norms and interpretation by trained neuropsychological assessors or experts; [0006] 4. The current evaluation method is complex and time-consuming, relying on outdated norms (developed 10 years ago) or lack of norms...
