The impact of alcohol on the brain: a growing concern
Drinking alcohol is a common practice and often associated with moments of relaxation or conviviality. However, the negative effects of alcohol on the body, especially as we age, are well known. According to recent research, it is becoming imperative to reconsider alcohol consumption to preserve health, particularly that of the brain.
In France, alcohol is deeply rooted in the culture, particularly through the consumption of wine, a national symbol, and the associated social traditions. However, alcohol consumption has declined in recent decades, although the country remains one of the most affected by alcohol-related problems, such as cardiovascular disease and premature mortality.
Despite prevention efforts and strict laws on sales and advertising, alcohol remains a major public health issue, particularly with excessive drinking among young people. Moderation and awareness of risks are essential to preserve health while maintaining traditions.
A clear recommendation from age 65
Neurologist Dr. Richard Restak, in his book The Complete Guide to Memory: The Science of Strengthening Your Mind (2021), warns of the effects of alcohol on the brain, especially after a certain age. “Alcohol is a neurotoxin, even in low doses, and it’s not good for nerve cells,” he explains.
Dr. Restak specifically recommends stopping alcohol consumption completely from the age of 65. At this age, the preservation of neurons becomes crucial, as the body begins to lose them naturally. Although this loss is relatively moderate – between 2% and 4% of neurons throughout life, according to studies by the British Psychological Society – caring for the remaining nerve cells becomes essential.
Why stop drinking after 65?
The main risks of drinking alcohol after this age include:
Cognitive deterioration : Alcohol affects the brain’s processing of information, increasing the risk of memory problems.
Risk of dementia : According to the Alzheimer’s Society in the United Kingdom, excessive drinking (more than 10 grams of alcohol per week) can seriously damage the brain, increasing the likelihood of developing dementia.
Physical risks : Older adults are more vulnerable to alcohol-related accidents, which can lead to serious injuries, which are of particular concern in older age.
Dr Restak advises gradually reducing alcohol consumption from the age of 65 to eliminate it completely by the age of 70. This change could make a significant difference in preserving cognitive and general health.
A global vision: moderation at all ages
Although stopping alcohol completely after age 65 is recommended, moderation is essential at any age. According to the World Health Organization (WHO), there is no “safe” level of alcohol consumption. Dr Carina Ferreira-Borges, WHO expert, specifies:
“From the first drop of alcohol, the health risk begins. The less you drink, the safer you are. »
A necessary action to preserve memory
For Dr. Restak, alcohol poses a particular threat to the memory and cognitive health of seniors. “Alcohol is a very, very weak neurotoxin, it is not good for nerve cells,” he emphasizes. He recommends:
“If you are 65 or older, I strongly advise you to completely and permanently eliminate alcohol from your diet. »
This preventive measure can help protect the brain and maximize quality of life in later years.
