Any alcohol use may raise dementia risk, new study finds, challenging claims that light drinking is protective.
A large study involving over 559,000 people from the UK and US finds that any alcohol consumption may increase dementia risk, challenging the idea that light drinking is protective.
Researchers from Oxford, Yale, and Cambridge analyzed health and genetic data, showing non-drinkers and heavy drinkers had a 41% higher risk than light drinkers, with a 51% increase among those with alcohol dependence.
Genetic analysis of over 2.4 million people linked higher alcohol use and dependency to greater dementia risk, with no evidence of benefit from low intake.
The findings, published in BMJ Evidence Based Medicine, suggest reducing population-wide alcohol consumption could help prevent dementia, especially as no current treatments can stop its progression.
