Drinking eight or more alcoholic beverages could have a harmful effect on the brain, according to a new study published in Neurology, The Medical Journal of the American Academy of Neurology (AAN).

This volume of alcohol was related to an increased risk of developing a type of brain injury called hyaline arteriolosclerosis, which causes narrowing and thickening of blood vessels and prevents blood flow in the brain.

This can lead to memory and cognition problems, according to a AAN press release.

“Heavy alcohol consumption is an important global health concern linked to the increase in health and death problems,” said study author Alberto Fernando Oliveira Justo, PHD, of the Sao Paulo University Faculty of Medicine in Brazil in Brazil, in the statement.

“We observe how alcohol affects the brain as people age. Our research shows that heavy alcohol consumption is harmful to the brain, which can lead to memory and thought problems.”

The researchers examined the cerebral autopsies of 1,781 people with an average of 75 years of age, focusing on any sign of brain injury or damage.

Then they gathered information on the alcohol consumption of the participants of the family members, according to the AAN statement.

Those who were classified as heavy drinkers had a 133% risk of having vascular brain lesions (abnormalities in the blood vessels of the brain) compared to the people who never drank.

The risk was 89% higher than former heavy drinkers and 60% higher than moderate drinkers.

Heavy drinkers and former heavy drinkers were also more likely to develop Tau tangles, which are protein deposits in the brain that are a common marker of Alzheimer’s disease.

When determining the level of consumption, the researchers defined a drink like containing 14 grams of alcohol, equating about 350 milliliters (ml) of beer, 150 ml of wine or 45 ml of distilled liquors.

Among those who used to be heavy drinkers, the researchers noticed a decrease in cognitive function and the lowest brain mass proportional to body mass, an effect that was not found among current heavy drinkers or moderate drinkers, according to the statement.

Heavy drinkers had a average shorter life of 13 years compared to those who never drank alcohol.

“Heavy alcohol consumption is an important global health concern related to the increase in health and death problems.”

“We discover that excessive consumption of consumption is directly related to signs of brain injuries, and this can cause long -term effects on brain health, which can affect memory and thought skills,” he said right in the statement.

“Understanding these effects is crucial for public health awareness and to continue implementing preventive measures to reduce excessive alcohol consumption.”

Dr. Frances Lee, who treats alcohol -related liver disease in Mount Sinai Health Systems in New York City, previously spoke with Fox News Digital about the effects of alcohol in the brain.

Lee said alcohol, a known depressant, easily crosses the Blood barrierthat plays a role in its depressive and addictive effects.

It has also been found that heavy alcohol consumption increases the risk of dementia, he warned.

“Alcohol intake can worsen the cognitive decline, causing problems with memory, as well as worsen some behavioral problems as depression“Davis told Fox News Digital.

A key limitation of the study is that it did not evaluate the health of the participants before death. There was also a lack of information about how much alcohol consumption lasted.

The researchers indicated that the study only shows an association and does not prove that excessive consumption of drink causes brain injuries.

The study was supported by the São Paulo Research Foundation.
