Title COGNITIVE FUNCTION EVALUATION APPARATUS, METHOD, SYSTEM, AND PROGRAM meetings
Abstract Provided are a cognitive function evaluation apparatus, which can be used with healthy people and people with severe movement disorders, a cognitive function evaluation method, a cognitive function evaluation system, and a program. The apparatus according to the present invention is for evaluating cognitive function and is provided with a processing unit, which: analyzes brain waves arising from multiple stimulus events comprising targets and non-targets; estimates the number of stimulus events selected as targets from among the multiple stimulus events and determines the discrimination score or decoding accuracy; and evaluates cognitive function on the basis of the values of one or more of the discrimination score, the decoding accuracy, the time course of either the discrimination score or the decoding accuracy, and decoding speed. It is also possible to determine discrimination score or decoding accuracy for each different degree of difficulty for two or more stimulus event groups that differ in the degree of difficulty in discriminating between stimulus events and to evaluate cognitive function on the basis of the relationship between one or more of the discrimination score, decoding accuracy, the time course of either the discrimination score or the decoding accuracy, and the decoding speed, and said degree of difficulty.
Scope of claims [claim1]
1.  There is provided an apparatus for evaluating the cognitive function,  The EEG is caused by a plurality of stimulation event consisting of target and non-target analysis process to, by estimating the stimulation event selected as a target from among the plurality of stimulus events, obtains a discriminant score or decryption precision, the discriminant score, the decryption precision, any time, and cognitive function evaluation apparatus characterized by comprising a processing unit for evaluating the cognitive functions based on one or more values ​​of the decryption speed.
[2]
[claim2]
2.  There is provided an apparatus for evaluating the cognitive function,  Difficulty of discrimination between stimulus event is different for at least two or more stimulus events group, the brain waves is caused by a plurality of stimulation event consisting of target and non-target analysis process to, from among the plurality of stimulation events and by estimating the stimulation event selected as the target, a different difficulty level every discriminant score or calculated decryption accuracy of the discriminant score, the decryption precision, any time, and one or more of the decryption speed, cognitive function evaluation apparatus characterized by comprising a processing unit for evaluating the cognitive function based on the association with the difficulty.
[3]
[claim3]
3.  Analyzing the EEG is caused by a plurality of stimulation event consisting of target and non-target, estimate the stimulus event selected as a target from among the plurality of stimulus events, it obtains a discriminant score or decryption accuracy, the determination scoring the decryption precision, any time, and based on one or more values ​​of the decryption speed, cognitive evaluation method and evaluating cognitive functions.
[4]
[claim4]
4.  Difficulty of discrimination between stimulus event is different for at least two or more stimulus events group analyzes the EEG is caused by a plurality of stimulation event consisting of target and non-target, a target from among the plurality of stimulation events the selected stimulus events estimated as, different difficulty level every discriminant score or calculated decryption accuracy of the discriminant score, the decryption precision, any time, and one or more of the decryption speed, the cognitive function evaluation method and evaluating cognitive functions based on the association with difficulty.
[5]
[claim5]
5.  By performing image processing on the image of the stimulus events, cognitive function evaluation method according to claim 4, wherein changing the difficulty level of discrimination between the stimulus event.
[6]
[claim6]
6.  A stimulus presentation device for presenting a stimulus, and electroencephalograph, a system for evaluating the cognitive function and a processing device for processing the EEG data from The brain wave detector,  The stimulus presentation device, a plurality of stimulation events consisting of target and non-target, respectively presented more than once,  The EEG measures the brain waves immediately after the stimulus presentation by the stimulus presentation device,  Said processing apparatus, the brain waves is caused by a plurality of stimulation event consisting of target and non-target analysis process to, by estimating the stimulation event selected as a target from among the plurality of stimulus events, discriminant score or decryption seeking precision, the discriminant score, the decryption precision, any time, and cognitive evaluation system and evaluating cognitive functions based on one or more values ​​of the decryption speed.
[7]
[claim7]
7.  The computer,  A stimulus presentation means for presenting a plurality of times a plurality of stimulus events, and analytical processing EEG data of an event-related potential immediately after the stimulus presentation, estimates the stimulus event selected as a target from among the plurality of stimulation events on determines the discriminant score or decryption precision, the discriminant score, the decryption precision, any time, and processing means for evaluating cognitive functions based on one or more values ​​of the decryption speed, the cognitive function program for functioning as a presenting unit for presenting the evaluation results.
