[Computer-aided visuospatial cognitive-performance test].
The validity of a newly developed computer-aided "Visuospatial Cognitive-Performance Test" (VCP-Test) was examined in two populations, 68 normal elderly volunteers (mean age, 69.5% years) and 25 patients with dementia (mean age, 68.2 years). None of the cases in the two groups had either motor impairment or ataxia. The VCP-Test was a kind of vigilance task in which a subject is required to tap the key corresponding to the local change-over of the image on the computer display as quickly as possible. After 40 trials, consecutive data of performance efficiency were automatically displayed on the LCD display and printed out. A significant negative correlation between the VCP-Test and age in normal elderly population was recognized. Moreover, the relationship between the VCP-Test and the Hasegawa Dementia Scale (HDS), and the Mini-Mental State (MMS) was also significant in patients with dementia. In conclusion, the VCP-Test was considered to be useful for geriatric neurobehavioral functional assessment and for the detection of dementia.
