The days of thinking of one -two drinks does not harm your health. In 2023, the World Health Organization confirmed that “no alcohol consumption is safe for our health.” The more you drink, the more you are prone to harmful health risks. A new study has shown that consuming eight and more alcoholic a week can significantly increase the risk Brain damage.
A study led by Albert Fernando Oliveira Justira, a candidate of the University of San -Paul Medical School in Brazil, showed that the presence of eight or more drinks a week is related to memory and difficulties of thinking. The study was published in neurology, medical journal of the American Academy of Neurology. The new study, however, does not prove that the strong consumption of alcohol causes brain injury, it only shows the association.
“Difficult alcohol consumption is a major global health problem associated with increasing health and death problems. We have considered how alcohol affects the brain when people age. Our study shows that in consuming alcohol damage to the brain, which can lead to memory and problems of thinking,” – said the author of the study by Albert Fernando. Brazil.
Alcohol and brain
To understand the influence of alcohol on the brain, the researchers studied 1781 people who are 75 years old at death. Everyone had a brain opening. The researchers sought signs of brain injury, including Tau Cautons and Hialin Arteralosis.
Hialin arteriolosclerosis is a condition that causes small blood vessels to narrow, becoming thick and rigid. This makes it difficult to blood flow, which can damage the brain over time. It seems like lesions, areas of damaged tissue in the brain.
Researchers also measured the brain mass and the height of each participant. Family members responded to the consumption of alcohol consumption.
For a better understanding of the participants, there were four groups: 965 people who never drank, 319 moderate alcoholics who had seven or less drinks a week; 129 heavy drunks who drank eight or more drinks a week; and 368 former heavy -forsters. One drink was defined as 14 gm of alcohol, which is about 350 milliliters (ml) of beer, 150 ml of wine or 45 ml of distilled spirit.
Researchers found that people who had never drunk had 40%had vascular brain lesions. Moderate drunks had 45%of the brain vascular lesions, and in heavy alcoholic beverages it was 44%, while the former heavy plays had 50%.
After considering the factors that could affect brain health, such as death, smoking and physical activity, in severe alcoholics, 133% more likely that vascular brain lesions compared to those who never drank, former severe fans had 89% more than 69%.
The study also found that heavy and former alcoholic lovers had a higher chance of developing TAU Tangles, a biomarker associated with Alzheimer’s disease, with 41% and 31% higher chances respectively.
In addition, the former heavy drunks had a smaller ratio of brain mass, which is a smaller brain mass compared to body weight and the worst cognitive abilities. In addition to brain injuries, they also had a violation of cognitive abilities. They also found that heavy drunkards died on average 13 years earlier than those who never drank.
“We have found that strong drinking is directly related to the signs of injuries in the brain, and this can lead to long-term exposure to brain health, which can affect memory and ability of thinking. Understanding these effects is crucial to health care and continues to implement preventive measures to reduce strong drinking,” said Just.
