Researchers analyzed data on 3,353 people enrolled in cohort studies in the U.S., Canada, and France. Participants had undergone testing and, for some, levels of proteins and genes associated with Alzheimer’s disease were available. Adults both with and without Alzheimer’s disease have better cognition skills in late summer and early fall than in winter and spring, with the odds of meeting diagnostic criteria for mild cognitive impairment or dementia increasing in winter and spring.
