Brain dysfunction assessment method, brain dysfunction assessment device, and program thereof

Abstract

A brain dysfunction assessment device (100) comprises: a body movement indicator (10) which presents a body movement to be performed to a subject with a body movement presentation device (2); a body movement data acquisition unit (20) which acquires the subject's body movement data with a body movement detection sensor (3); a body movement accuracy calculation unit (30) which calculates a positional accuracy and a time sequence accuracy of the subject's body movement from the acquired body movement data; and a cognitive dysfunction assessment unit (40) which assesses the level of cognitive dysfunction of the subject by comparing a value which indicates the accuracy of the subject's body movement that is obtained from the calculated positional accuracy and time sequence accuracy with statistical data which indicates the accuracy of body movement of healthy individuals.

Description

technical field [0001] The present invention relates to a technique for evaluating the degree of brain dysfunction including a decrease in cognitive function. Background technique [0002] In recent years, with the development of aging society, the number of dementia patients has increased, and it is said that there are currently 2 million dementia patients in Japan. Dementia causes memory impairment, disorientation, learning impairment, etc., and has a great impact on daily life. In addition, cases of problem behavior such as verbal abuse, violence, loitering, and obscene behavior were also found. Furthermore, in the final stage, motor disturbances such as walking in small steps and leaning forward were shown, and finally fell into a bedridden state. [0003] Among dementias, in addition to the three major dementias of Alzheimer's disease, cerebrovascular dementia, and Lewy body dementia, there are also mental disorders such as movement disorders such as Parkinson's disea...
