How does alcohol affect the human brain?

Consuming alcohol has a negative effect on the work of the brain, which is why it is especially dangerous for our health. In the case of single and short-term drinking of alcoholic beverages, there is a temporary loss of consciousness, behavioral control and emotional lability. A person in a state of intoxication does not control his behavior, then destructive actions may appear, such as self-mutilation, excessive aggression and a tendency to forbidden acts (theft, fights, acts of vandalism).


On the other hand, long-term consumption of alcoholic beverages permanently damages the structures of nervous connections, leading to irreversible changes in the central nervous system. The human brain is an extremely sensitive and sensitive organ. Any injuries caused by external factors regenerate very slowly.


The damage caused by consuming alcohol in large amounts over a long period of time is irreversible. Then, nerve connections are degraded and the brain gradually atrophies. Its volume decreases as a result of contraction, causing impairment of all activities necessary for the proper functioning of a human being. The brain is the main organ responsible for the proper functioning of organs and stimulating proper behavior.


As a result of alcohol consumption, its functions are disturbed. There are various types of somatic diseases (cirrhosis, heart disorders), mental and neurological diseases. Young people and women should pay particular attention to the destructive effects of alcohol on the central nervous system, as they are the most vulnerable to negative effects. Alcohol impairs the functioning of the limbic system responsible for memory, concentration and maintaining normal emotions. In the neurons of the amygdala (which is part of the abovementioned limbic system), the protein balance is disturbed, which in turn causes anxiety in adulthood.


Permanent damage in the limbic system (also in the hippocampus, which is its main element) leads to impaired absorption and memorizing of new content. Cognitive functions are disturbed, there is premature intellectual dullness, and loss of analytical skills and logical thinking. Long-term alcohol consumption also contributes to enduring emotional instability. However, in the advanced stages of the development of alcoholism, auditory, olfactory or visual hallucinations appear, as well as depressive states and frequent nervous breakdowns leading to suicide attempts.
