l’alcohol it hurts even if taken infrequently, sporadically and in small doses. If overused, it causes 60 types of health damage, including heart disease, cancer and brain damage. However, it has been reported that even light or moderate alcohol consumption can alter the brain and lead to: cognitive disorders. A recent study found that light or moderate alcohol consumption leads to brain reductions. Drinking about two beers produces a variation in gray and white matter that is equivalent to more than 10 years of maturation.
Henrike Scholz and his team used a genetic model of the fruit fly and found that drinking alcohol changes two areas of the brain. These are the mitochondrial dynamics and the balance between synapses in neurons. Mitochondria are the ones that bring energy to cells, especially nerve cells. Here it was observed how in the alcohol-treated cells the mitochondria had an altered movement, as well as the chemical balance between synapses.
In short, it has been shown that even one single dose of alcohol can change the perm morphology of neurons e create addiction of alcohol. Morphological changes appear to be influenced by ethanol-associated memory formation. Scientists have theorized that the brain changes caused by alcohol use are essential for developing addiction. Even one experience of alcohol dependence can increase alcohol consumption or cause a relapse later in life.
We went in search of ethanol-dependent molecular changes. These in turn form the basis for permanent cellular changes after a single acute ethanol intoxication. The effects of a single alcohol administration were examined at the molecular, cellular and behavioral levels. These mechanisms may also be relevant in humans. This means that a first alcohol intoxication at a young age can be an important risk factor for a subsequent alcohol intoxication and the development of alcohol dependence later in life. Identifying lasting changes caused by alcohol is thus an important first step in understanding how acute alcohol use can turn into chronic alcohol abuse.
