Why the Risk Increases Even with Small Amounts
A study analyzed data from over half a million people. Over several years, nearly 15,000 participants were diagnosed with dementia. The researchers found that regular alcohol consumption—even as little as seven drinks a week—increases the risk of developing dementia. For those who consumed more than 40 servings of alcohol per week, the risk increased by more than 40%.
Experts emphasize that early declines in cognition may lead people to cut back on drinking long before a diagnosis is made. However, that doesn’t mean small amounts are safe—the research suggests the opposite, reports Daily Mail.
Experts’ Opinions
Dr. Anya Topivala from the University of Oxford stated, “The common belief that small doses of alcohol are beneficial for the brain lacks scientific support. Genetic data suggests otherwise.”
Her colleague, Professor Joel Gelernter from Yale University, added, “We have long thought that light drinking could be neutral or even beneficial. The latest research shows that this is a misconception.”
However, other specialists urge caution, reminding us that while the link between alcohol and dementia is supported by numerous studies, proving a direct cause-and-effect relationship remains challenging.
Official Recommendations
The National Health Service (NHS) in the UK advises not to exceed 14 units of alcohol per week. This is roughly equivalent to six glasses of wine or six pints of beer. In the U.S., recommendations differ: women are advised to limit themselves to no more than seven drinks per week, while men can have up to 14.
However, new findings call even these so-called safe limits into question. According to the researchers, each additional serving of alcohol increases the risk of brain harm.
Alcohol and Brain Health: What’s Next
Currently, around 982,000 people in the UK live with dementia. By 2040, that number could rise to 1.4 million. Researchers emphasize that reducing alcohol consumption could be a viable prevention strategy—alongside managing cholesterol levels, controlling blood pressure, and quitting smoking.
Scientists stress that when it comes to brain health, there is no such thing as a “safe” drink.
