People who drink no alcohol at all as middle-aged, especially no wine, are at increased risk of developing dementia in their elderly than those who consume them in a moderate way, according to a new British-French study. Total abstinence from alcohol is associated with an average 45% increase in dementia, compared to those who drink up to one and a half bottles of wine per week. But if you drink more then the risk of dementia increases over time.
And the more he drinks after a limit, the probability of dementia is rising. This limit is 14 units of alcohol per week. As one unit equals 10 ml or 8 grams of pure alcohol, about three units of alcohol are contained in a large glass of 250 ml wine (almost one-third of the bottle).
Researchers at the University College London (UCL) and the French Institute of Health INSERM, headed by epidemiologist Sevein Sambia, who published the report in the British medical journal British Medical Journal, analyzed data for 9,087 people aged 35 to 55 , of which 397 had dementia over 23 years.
It was found that the longer the absolute abstinence from a person’s alcohol was, the greater the risk of subsequent dementia. So those who did not put a drop of alcohol in their mouth well before the middle age, had a 67% greater probability of dementia.
“We have shown that both long-term abstention and excessive consumption can increase the risk of dementia,” the researchers said, and pointed out that prevention should be a priority given that dementia worldwide are expected to triple by 2050.
The study also found that those who are totally absent from alcohol are at most risk of diabetes and heart disease, two diseases that are a risk factor for dementia. Some previous studies have also shown that moderate alcohol consumption reduces cholesterol and blood pressure, thus protecting against diabetes and cardiovascular risks.
However, the researchers said they thought it premature to advise anyone who does not drink any alcohol, start drinking, especially if they have a history of heavy drinking in the past. They also pointed out that even low alcohol consumption may increase the risk for other conditions such as cancer, so it is difficult to see officially as completely safe drinking.
“We are not yet at the point where we can say that alcohol consumption is good for the brain, but it is good that we have identified a” threshold “beyond which the chances of dementia are increasing,” Sabbia said, according to British “Indipendent” and “Telegraph”.
