Alcohol Consumption Can Cause Modifications In The Architecture And Function Of The Growing Brain

Alcohol consumption can cause changes in the architecture and operation of the blossoming brain, which continues to grow into a person's mid 20s, and it may have consequences reaching far beyond adolescence.

In adolescence, brain development is identified by remarkable modifications to the brain's structure, neuron connectivity ("electrical wiring"), and physiology. These transformations in the brain disturb everything from emerging sexuality to emotionality and judgment.

Not all component parts of the adolescent brain mature at the same time, which might put a juvenile at a disadvantage in certain circumstances. For instance, the limbic regions of the brain mature quicker than the frontal lobes. The limbic regions control feelings and are related to a juvenile's lowered sensitivity to risk. The frontal lobes are responsible for self-control, judgment, reasoning, problem-solving, and impulse control. Variations in maturation among parts of the brain can result in careless choices or acts and a neglect for consequences.

The way Alcohol Disturbs the Human Brain Alcohol alters a juvenile's brain growth in numerous ways. The results of minor alcohol consumption on particular brain activities are discussed below. Alcohol is a central nervous system sedative. Alcohol can appear to be a stimulant because, before anything else, it depresses the portion of the brain that controls inhibitions.

CORTEX-- Alcohol impedes the cerebral cortex as it processes information from an individual's senses.

CENTRAL NERVOUS SYSTEM-- When a person thinks of something he wants his body to undertake, the central nervous system-- the brain and the spinal cord-- sends a signal to that portion of the physical body. Alcohol slows down the central nervous system, making the individual think, converse, and move less quickly.

FRONTAL LOBES -- The brain's frontal lobes are very important for organizing, forming concepts, making decisions, and using self-control.

Once alcohol impacts the frontal lobes of the brain, a person might find it hard to control his/her emotions and impulses. The individual may act without thinking or might even get violent. Consuming alcohol over a long period of time can damage the frontal lobes permanently.

HIPPOCAMPUS-- The hippocampus is the part of the human brain where memories are created. When alcohol gets to the hippocampus, a person may have trouble recollecting something she or he just learned, such as a name or a telephone number. This can take place after just one or two alcoholic beverages. Drinking a lot of alcohol rapidly can trigger a blackout-- not having the ability to remember entire happenings, like what exactly he or she did the night before. If alcohol harms the hippocampus, a person might find it hard to learn and to hold on to information.

CEREBELLUM-- The cerebellum is essential for coordination, ideas, and attention. Once alcohol goes into the cerebellum, an individual may have difficulty with these abilities. After consuming alcohol, a person's hands may be so tremulous that they can't touch or grab things normally, and they may fail to keep their equilibrium and tumble.

HYPOTHALAMUS-- The hypothalamus is a little part of the brain that does an incredible number of the body's housekeeping tasks. Alcohol frustrates the work of the hypothalamus. After an individual drinks alcohol, blood pressure, hunger, being thirsty, and the need to urinate intensify while body temperature and heart rate decline.

Alcohol actually chills the physical body. Consuming a lot of alcohol outdoors in cold weather can cause a person's body temperature to fall below normal.

An individual might have difficulty with these abilities when alcohol enters the cerebellum. After consuming alcohol, an individual's hands might be so unsteady that they cannot touch or grab things normally, and they might fail to keep their balance and fall.

After a person alcoholic beverages alcohol, blood pressure, hunger, being thirsty, and the desire to urinate increase while body temperature levels and heart rate decrease.

Alcohol in fact chills the body. Consuming a lot of alcohol outdoors in cold weather can cause a person's body temperature level to fall below normal.
