Alcohol Changes Brain Activity: Here’s How It Works

The alcohol alters brain activity because a high consumption of it occurs. This is reflected in a study published in the journal ‘in Euro‘ and that it was made with mice. The research reflects how synchronized brain activity in the amygdala of rodents is altered by their consumption.

As the study authors explain, alcohol consumption has a strong comorbidity with mood disordersespecially with anxiety and depression. The amygdala, one of the main regions of the brain, is implicated in both alcohol use disorders. Oscillations, which are changes in brain activity, control the behavioral expression of fear and anxiety.

To carry out this research, the experts administered alcohol to rodents. A method that ended with different results for male and female mice. In fact, in the second case, there were practically no significant changes in the oscillatory state of the amygdala, a completely different case from that of male rodents.

The researchers suggest that acute and repeated exposure to alcohol can cause changes in the activity of the amygdala, which in turn would lead to changes in fear and anxiety behaviors. “It’s him first study showing that alcohol is able to modify network states implicated in anxiety and alcohol use disorders. The data potentially point to a new mechanism that mediates the effects of alcohol on affective states.”

Among the main causes of these changes would be the anxiolytic properties of alcohol, although the researchers themselves have pointed to this finding. “However, it is unknown how alcohol affects network states underlying the modulation of anxiety states”.

The risks of long-term alcohol consumption

As stated on its website, the Centers for Disaster Control and Prevention (CDC) of the United States, among the risks of long-term alcohol use Some end up like hypertension, cardiovascular disease, stroke, liver disease, and digestive system problems. Certain types of cancer are also found, such as those of the breast, mouth, throat, larynx, esophagus or liver.

In the case of Spain, according to the Ministry of Health in a report, alcohol consumption is also widespread among the general population aged 15-64. Up to 93% of the population has consumed alcohol at some point in their life.
