These activities could help postpone Alzheimer’s by 5 years, study suggests

A study of 1,939 older adults found a 38% lower Alzheimer's risk and delays in onset by 5 to 7 years linked to lifelong language and cognitive activities.

  • Published this month in Neurology, a Rush University Medical Center research team found higher lifetime cognitive enrichment linked to a 38% lower Alzheimer’s risk in 1,939 study participants aged 80.
  • Researchers surveyed participants about early life, midlife and later life activities, and calculated scores comparing the top and bottom 10%.
  • During follow-up, 551 participants developed Alzheimer’s and 719 developed mild cognitive impairment; those with the highest enrichment were diagnosed five to seven years later, and autopsy data showed better cognition despite similar amyloid and tau levels.
  • The study authors note it shows an association, not proof of causation, and relied on participants’ retrospective recall, while emphasizing that enrichment is not simply a proxy for socioeconomic status and urging public investments in libraries and early education programs.
  • The findings align with the cognitive reserve idea popularized by Yaakov Stern and echo related studies on dance, music and social ties, while experts called the results encouraging for prevention.
