Stereoscopic vision in patients with Alzheimer's disease

Abstract

The present study investigated the effects of Alzheimer’s disease (AD) on stereoscopic vision. Sixty participants (20 AD patients, 20 mild cognitive impairment patients, and 20 healthy elderly controls) participated in the study. Two cubes appeared at varying distances from the observer with their relative distances controlled in two disparity conditions (i.e., absolute vs relative disparity) combined with two disparity directions (i.e., crossed vs uncrossed disparity). Results demonstrated comparable performance with all three groups performing accurately.
