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
