Frequent use of alcohol increases the risk of vascular problems in the brain and is one of the factors in the development of dementia, the report according to the latest study says.
He published In the journal Neurology. The results of the study claim that alcohol lovers can experience Significant deterioration of cognitive abilities. How tells The publication MedicalNewstuday, as part of their work, scientists investigated the brain of 1781 participants in the study, the data are contained in the biobank of aging studies in the Autopsy service of San Paulo (Brazil).
The average age of the participants was approximately 75 years, and the sample was ethnically diverse. Information about the lifestyle of participants, scientists also clarified their relatives. Having collected the data, Researchers divided the participants into several categories:
- Those who did not drink alcohol at all;
- moderately drinking;
- They drank often and a lot.
After that, scientists began to study their brain, looking for manifestations of dementia. According to the results of the study, People who often consumed alcohol in large doses had a 133% higher risk of arteriolosclerosis* (changes in the structure of arteries in the brain). In abuse of alcohol, the risk of neurofibrillar balls (plexus of fibers inside nerve cells associated with the pathology of Alzheimer's disease) increased.
The author of the study by Alberto Khusto, a researcher at the Medical School of the University of San Paulo, noted:
“The study revealed that even Moderate consumption Alcohol can lead to vascular changes in the brain. This emphasizes that alcohol even in moderate quantities can have a significant effect on the health of the brain. ”
It also turned out that Former alcoholics were much worse than cognitive abilities compared to those who had never drank. Intensive alcohol consumption can lead to an accelerated subcortical disease in the brain, which will appear as cognitive impairment.
“Such people can progressively demonstrate weakness, slowdown of thinking, memory problems,” said the doctor of medical sciences, a neurologist from Memorial Hermann Haris Kamal, who did not participate in the study.
In the future, scientists plan to concentrate on the study of causal relationships between prolonged use of alcohol and its effect on the brain. Alberto Huso says:
“This study will help to find out how different levels and the duration of alcohol consumption affect cognitive health.”
We previously wrote about at what age should you quit drinkingto avoid dementia.
*Arteriosclerosis (arteriosclerosis, Hardening of the Arteries) – sclerosis of the arteries, is a chronic arterial disease expressed in diffuse thickening of their walls or in the form of individual plaques.
