  • The research showed that both non-drinkers and heavy drinkers had a higher risk of dementia compared to light drinkers, challenging previous beliefs about light drinking being beneficial.
  • Dr Anya Topiwala stated that the findings contradict the belief that low alcohol levels benefit brain health, suggesting a need for reduced consumption.
  • Researchers used genetic analysis to determine the cause of dementia, finding that higher alcohol consumption correlates with increased dementia risk, contrary to previous studies.
