Pupil dilation as a marker of attention/effort in aging and mild cognitive impairment

Key Points

To explore how pupil dilation can reflect cognitive function in individuals with healthy aging and mild cognitive impairment.
Utilized pupil dilation measurement as an assessment tool
Analyzed changes in pupil response to cognitive tasks
Focused on both aging adults and individuals with mild cognitive impairment
Pupil dilation correlates with levels of attention and effort in cognitive tasks
Significant changes in pupil response observed in mild cognitive impairment compared to healthy aging

Abstract

Measurement of PD may serve as an easy-to-administer measure to assess changes in cognitive function in healthy aging and MCI.
