Any Amount of Alcohol May Increase Dementia Risk, Study Finds

Genetic and observational data from over 559,000 adults show dementia risk rises by 15% with just 1-3 drinks weekly, challenging beliefs about safe alcohol levels.

  • Drinking any amount of alcohol may increase the risk of developing dementia, according to a study by researchers at the University of Oxford, Yale University, and the University of Cambridge.
  • The study found that heavy drinkers had a 41% higher risk of dementia compared to light drinkers who consumed fewer than seven drinks per week.
  • There is no protective effect of low-level drinking on brain health; evidence suggests it could be harmful, according to Dr. Anya Topiwala.
  • The researchers indicated that reducing alcohol consumption could play a significant role in dementia prevention and emphasized the need for further research on alcohol's impact on brain health.
