Alcohol and Dementia Risk: Drinking alcohol in any amount can negatively impact the brain and increase the risk of dementia, a new study has revealed.

Alcohol and Dementia Risk: Drinking alcohol has become commonplace these days. However, a recent study has issued a warning. According to this research, drinking alcohol in any quantity can negatively impact the brain and increase the risk of dementia . Previous studies suggested that light or moderate alcohol consumption could be beneficial for the brain, but a recent study has completely challenged this notion.
Drinking alcohol increases the risk of dementia
Lead researcher Dr. Anya Topiwala of the University of Oxford says that even light or moderate drinking can increase the risk of dementia . Drinking alcohol at any level has negative effects on the brain .
Even mild or moderate consumption is not safe.
Some previous research suggested that light and moderate alcohol consumption may reduce the risk of dementia compared to non-drinkers. However , the new study , based on genetic analysis , completely refutes this . The study clearly demonstrates that biologically , or genetically , increased alcohol consumption also increases the risk of dementia , even if the alcohol intake is moderate .
Alcohol drinkers were divided into categories
- Heavy drinkers : 40 or more drinks per week
- Moderate drinkers : 7 to 14 drinks per week
- Light drinkers : fewer than 7 drinks per week
- The risk of dementia was found in all these categories , with the researchers saying that the risk was even higher among heavy drinkers .
It is important to reduce alcohol.
The research findings suggest that reducing alcohol consumption at the population level is crucial for preventing dementia . Whether a person drinks lightly , moderately , or heavily , the risk exists for everyone , making this message particularly important for those already at risk for alcohol addiction .
Recent studies have made it clear that there is no safe limit for alcohol consumption . Even light or moderate drinking can negatively impact the brain and memory . If you want to keep your brain and memory healthy , the safest course of action is to moderate your alcohol consumption , and if necessary , to abstain completely .
