Eye Trouble Can Lead to Lower Cognitive Test Scores for Seniors

In a recent experiment, researchers asked 24 older adults with normal vision to take both visual and oral cognitive tests with and without goggles that simulate age-related macular degeneration. Investigators found that when the participants experienced impaired vision, their performance on vision-based cognitive assessments fell. Study leader Dr. Anne MacNamara adds, “A mistaken score in cognitive tests could have devastating ramifications, leading to unnecessary changes to a person’s living, working, financial, or social circumstances.” Scientific Reports, May 2022
