Heavy drinking has been found to increase the risk of brain injury, leading to memory and thinking problems. A new study published in Neurology defines heavy drinking as eight or more alcoholic drinks per week. Researchers analyzed over 1,700 people who had an average age of 75 at the time of their death and found that heavy drinkers had a 133% higher likelihood of developing hyaline arteriolosclerosis, a lesion associated with memory problems.
Heavy drinkers also experienced higher rates of tau tangles, which are linked to Alzheimer’s disease, and died on average 13 years earlier than those who never drank. Former heavy drinkers showed evidence of sustained damage even after stopping drinking. While the study’s findings are compelling, it is essential to note that they are associations, not proof of cause and effect.
Dr. Leana Wen, an emergency physician and expert in wellness, explains that excessive alcohol consumption can disrupt brain communication pathways and impair cognitive function. The study’s results support what is already known about the effects of alcohol on the brain, including its potential to lead to premature aging and shrinking of brain tissue.
According to Dr. Wen, adults should limit their daily drink intake to one drink per day for women and two drinks per day for men. However, some people may be considered heavy drinkers despite meeting these guidelines due to factors such as binge drinking or consuming multiple drinks on different days.
Recognizing signs of problem drinking is crucial, especially if it affects loved ones. Dr. Wen emphasizes that individuals can screen themselves using self-questionnaires and look out for warning signs such as loss of control over drinking habits or physical symptoms like nausea when stopping drinking.
The debate surrounding whether it’s necessary to completely abstain from alcohol or if there’s a way to have a healthy relationship with it is ongoing. While excessive drinking poses significant risks, research suggests that even moderate consumption may be associated with negative consequences. Dr. Wen advises individuals to assess their relationship with alcohol by taking sobriety challenges and seeking help from mental health professionals if needed.
Ultimately, being aware of the potential risks and taking proactive steps can help individuals make informed decisions about their drinking habits and prioritize their overall well-being.
