Mentation test method and mentation test apparatus
First Claim
1. A mentation test apparatus comprising:
- a display means for displaying images by electronic control;
a transparent touch panel overlaid on a screen of the display means;
an image control means for randomly disposing and displaying a given number of targets to be pointed to in a prescribed order on the screen by controlling the display means, and for erasing the targets that have been pointed to in a correct order when a test subject points to the targets by pressing a position corresponding to each target on the touch panel in a prescribed order;
a time counter for measuring a search response time required by the test subject for searching each of the targets in a correct order and the search response time required by the test subject for searching the given number of targets in correct sequential order, and a processing means for calculating the mentation of the test subject based on the search response times measured by the time counter and the sequential order.

Abstract
A mentation test method that can test mentation of a human such as conjecture of brain'"'"'s mentation age, discrimination of early stage of dementia and prediction of onset of dementia in addition to diagnosis of prediction probability of onset of dementia and screening of mental functions of senile dementia patients, decision of the effect of rehabilitation of the aftereffects of cerebrovascular disfunction, investigation of the therapeutic effects of medicines and side effects such as sleepiness, testing of degree of intoxication, testing of peripheral attention visual field, testing of cerebral dominant hemisphere, testing of various psychoneurosis such as schizophrenia and cerebrovascular disorder (syndrome and diagnosis, and decision of the effects of rehabilitation and treatment), and check of the degree of fatigue.

an image control means for randomly disposing and displaying a given number of targets to be pointed to in a prescribed order on the screen by controlling the display means, and for erasing the targets that have been pointed to in a correct order when a test subject points to the targets by pressing a position corresponding to each target on the touch panel in a prescribed order; and
a time counter for measuring a search response time required by the test subject for searching each of the targets in a correct order and the search response time required by the test subject for searching the given number of targets in correct sequential order, and a processing means for calculating the mentation of the test subject based on the search response times measured by the time counter;
wherein the image control means includes;
a function for controlling the display means to erase a target from the screen when the target is pointed in a correct order, and to display a dummy target having a different color at the position of the target in place of the target that has been erased;
a function for controlling the display means to erase a target from the screen when the target is pointed in a correct order, and to display a dummy target at random positions in place of the target that has been erased;
a function for controlling the display means to erase a target from the screen when the target has been pointed in a correct order, and to display a dummy target at random positions in place of the target that has been erased, while controlling the display means to display each target and dummy target by changing their display positions; and
a selection means for making any one of the functions effective, wherein the mentation age of the test subject'"'"'s brain is calculated by the processing means based on the search response time measured by the time counter in a test using each function.
