We know that alcohol is a risk to our health Even in small doses. However, it is also known that the problems associated with alcoholic beverages grow significantly when we exceed the limits of what we call “moderate consumption.”
Like a brain injury. A new study has observed That excessive alcohol consumption was related to the appearance of hyaline arterosclerosis, a disorder linked to brain lesions. The team highlights that, the association observed between alcohol and disorder should not be understood as proof in itself that alcohol is causing brain injuries.
“Severe alcohol consumption is an important global public health problem linked to an increase in health problems and death,” pointed in a press release Alberto Fernando Oliveira Justo, co -author of the study. “We observe how alcohol affects the brain according to people age. Our research shows that excessive alcohol consumption damages the brain, which can lead to memory and cognition problems.”
Hyaline artosclerosis. As explained by the study responsible for the study, the Hyaline artosclerosis It is a disorder that causes narrowing of some blood vessels, which makes them thicker and rigid. This in turn makes it difficult to flow from blood and therefore end up causing damage to the brain. This disorder can be originated in areas of the brain where there have been damaged injuries or tissue. Another disease linked to this disorder is Diabeteswhich can cause similar effects concentrated in the kidneys.
From autopsies. In his study, the team responsible for the analysis had 1,781 participantsalready killed ages above 75 years. To study the impact of alcohol in their brains, cases in which brain autopsies of the bodies were used. Thus the equipment was able to look for signs of brain injuries such as TAU protein accumulations and signs of hyaline arterosclerosis.
How much is a lot. The question of How much alcohol is a lot of alcohol It is difficult to answer clearly and concisely. The tolerance of our body with respect to this substance depends on factors such as our age, sex or body mass. In his study, the team conducted interviews with the relatives of the deceased people on which the study was based.
From the information they classified these people among those who never drank (965 people in this group); moderate drinkers (319 participants); excess drinkers (129 people); and ex -owners who did it in excess (368 people).
Finding the relationship. Once other factors were controlled, the team estimated that people in the category of excessive consumption had a risk of cerebral vascular lesions 133% higher than those who did not drink. The risk was 89% higher in the case of former owners and 60% higher in the case of those who drank moderately.
The team also found indications of a relationship between alcohol consumption and the appearance of tau clusters, although this was a lower magnitude than that observed with hyaline arterosclerosis. The details of the study were published In an article In the magazine Neurology.
A difficult balance. The team also observed other relationships in its study. For example cognitive problems that manifested between drinkers or a 13 -year reduction in the life expectancy of excess drinkers with respect to non -drinkers.
The study represents a new test of the risks associated with alcohol. It is not rare to find information about the benefits of low gradation drinks such as wine but experts usually coincide in pointing out that, in regard to health, risks exceed possible benefits. In any case, these risks increase with consumption, something that we must also take into account.
