Cognitive assessment system and application thereof

Abstract

The invention designs a cognitive assessment system comprising an information module, a test module and an analysis module. The information module is used for getting medical information matching the test module according to the data of an object and building a complete cognitive assessment database. The test module gets cognitive test data of the object through test, and includes the following five sub modules: an attention and executive function test module, a memory test module, a mathematics and computing power test module, a language test module, and an action and behavior control and plan test module. The analysis module determines the cognitive assessment result of the object according to the medical information acquired by the information module and the cognitive test data acquired by the test module. According to the invention, all sorts of cognitive functions are refined, mutual interference between cognitive domains is minimized by understanding the relationship and mutual influence between different capabilities, and the cognitive situation of an object is evaluated objectively to help clinicians to make an individualized rehabilitation plan for the assessment object.

Description

technical field [0001] The invention relates to the field of cognitive evaluation, in particular to a cognitive evaluation system and its application. Background technique [0002] Stroke is a disease with high morbidity and high disability rate, and it is also the most common cause of vascular cognitive impairment and dementia, which can cause various functional impairments including motor and cognition. Cognitive impairment caused by stroke can involve multiple cognitive functional domains, thus seriously affecting patients' daily life and functional rehabilitation. Early cognitive screening and intervention may improve the prognosis. The 2011 Chinese Guidelines for Stroke Rehabilitation Treatment recommended early cognitive function screening, and basic disease assessment including cognitive function evaluation should be performed within 14 days after the onset of the disease. However, at present, more attention is paid to the evaluation and recovery of limb dysfunction ...

AI Technical Summary

Problems solved by technology

The purpose of the MMSE scale is to screen for dementia. There is a ceiling effect, and it is not sensitive enough to mild cognitive impairment. Poor screening for cognitive impairment

Although the recognition rate of MOCA for mild cognitive impairment including vascular cognitive impairment is better than that of MMSE, MoCA was originally designed to identify early cognitive impairment (Mild Cognitive Impairment: MCI), not patients with vascular cognitive impairment , which is deficient in assessing several cognitive impairments commonly seen in post-stroke patients, including practical ability, neglect of symptoms, and impaired reading and writing

At the same time, neither of the above two scales is suitable for patients with aphasia, spatial neglect, and executive dysfunction, and the specific items they contain largely need to be completed through verbal expression

Therefore, patients with aphasia, spatial neglect, or executive dysfunction after stroke cannot objectively evaluate their memory, attention, and other cognitive functions through the MoCA scale.

Other commonly used assessment tools include Alzheimer's disease assessment scale-cognition (ADAS-cog), Hasegawa's dementia scale (HDS-R), etc. However, these scales are also for the purpose of screening for dementia, lacking the detection of executive function and other items, and cannot meet the needs of evaluating vascular cognitive impairment

And a set of neuropsychological tests that can comprehensively assess patients' cognitive status, such as the World Health Organization battery of cognitive assessment instruments for elderly (WHO-BCAI), is also aimed at senile dementia, and is relatively Difficult to obtain and master, unable to be widely used, mostly used in scientific research
