Paper Abstract

The pupil responses of 15 cognitively normal subjects (ages 60-74) were examined in response to 76 focal red and blue light stimuli using a chromatic multifocal pupillometer (CMP). Subjects with low cognitive scores as determined as by Montreal Cognitive Assessment testing, presented significantly weaker and sluggish pupil responses in peripheral and central locations of the visual field in response to red and blue light. Our findings suggests that the CMP may present a novel objective, non-invasive, low cost technique for early diagnosis of cognitive decline that may serve for Alzheimer Disease prevention and as sensitive outcome measure of therapeutic effects.
