Abstract in brief

  • This meta-analysis found that current smokers are at a higher risk of developing all-cause dementia, Alzheimer's disease, and vascular dementia compared to never smokers, with the risk increasing with the number of cigarettes smoked daily.
  • Former smokers do not show a significantly increased risk of dementia, suggesting that quitting smoking may decrease the risk down to levels similar to never smokers.
  • The increased risk of Alzheimer's from smoking was mainly observed in apolipoprotein E 4 noncarriers, and certain age groups (65-75 years) are more affected, while factors like sex, race, and study location did not significantly alter the risk.
