眼球運動計測を用いた痴呆簡易診断システムの基礎研究

Abstract

A new dementia diagnostic method is proposed based on the oculogyration including smooth pursuit eye movements. The response curves are processed with summation-averaging method in order to eliminate the random saccade eye movements. The subjects groups are composed of 19 Alzheimer type dementia, 18 normal elders and 7 young-volunteers. Several parameters including delay time, switching time of internal and lateral rectus muscles and peak response values are measured with successfully discriminating diagnosis between the patients and the normal. The method may be a useful arsenal for evaluation in the screening of the demented people in future.departmental bulletin pape
