In Alzheimer's disease (AD), we studied how to get visual information and use it for doing performance by recording EMV with EMR-8 (NAC Inc.). The subjects were four AD patients (MMSE source more than 21) and four age-matched controls. They performed the touch-panel computer task, which was to touch the cell (3-6 divided) in the same order as it appeared on the screen. In the correct performance to the tasks which were the cell moving neighbor position, the EMV of AD was the same as the control. However, in the error performance, the EMV of AD could not almost catch the next cell which moved randomly. In AD, their cognitive visual field seemed to be smaller than the control.
