Lifetime Cognitive Enrichment Associated With Less Dementia
A longitudinal analysis of 1,939 Rush Memory and Aging Project participants found that greater lifetime cognitive enrichment—particularly midlife cognitive activities and foreign language instruction—was associated with a mean Alzheimer’s dementia onset delay of about 5.5 years, a 7-year delay for mild cognitive impairment, and an estimated 40% lower dementia risk; cohort was mostly highly educated, non-Hispanic White, followed annually for nearly eight years.
