Alcohol Consumption Can Cause Alterations In The Structure And Function Of The Blossoming Brain

Alcohol consumption can cause alterations in the structure and operation of the growing brain, which continues to grow into a person's mid 20s, and it may have repercussions reaching far beyond teenage years.

In adolescence, brain development is defined by remarkable changes to the brain's architecture, neural connections ("electrical wiring"), and physiology. These transformations in the brain affect everything from emerging sexuality to emotions and judgment.


Not all parts of the juvenile brain mature concurrently, which may put an adolescent at a disadvantage in specific circumstances. For example, the limbic regions of the brain mature quicker than the frontal lobes. The limbic regions regulate feelings and are related to an adolescent's lowered level of sensitivity to risk. The frontal lobes are responsible for self-control, judgment, reasoning, problem-solving, and impulse control. Variations in maturation amongst parts of the brain can lead to impulsive decisions or acts and a disregard for repercussions.

How Alcohol Alters the Brain
Alcohol alters an adolescent's brain development in many ways. The repercussions of adolescent drinking on particular brain functions are summarized below.
Alcohol is a central nervous system sedative drug. Alcohol can appear to be a stimulant because, at the start, it depresses the part of the human brain that governs inhibitions.

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

CENTRAL NERVOUS SYSTEM-- When a person thinks about something he wants his body to do, the central nervous system-- the brain and the spine-- sends out a signal to that portion of the body. Alcohol hinders the central nervous system, making the individual think, speak, and move slower.

FRONTAL LOBES -- The brain's frontal lobes are necessary for advanced planning, forming concepts, decision making, and exercising self-control.

Once alcohol affects the frontal lobes of the brain, an individual might find it tough to manage his/her feelings and urges. The individual may act without thinking or may even become violent. Drinking alcohol over a long period of time can harm the frontal lobes permanently.

HIPPOCAMPUS-- The hippocampus is the part of the brain where memories are generated.
When alcohol gets to the hippocampus, an individual may have trouble recollecting something he or she just learned, like a name or a telephone number. This can take place after just one or two drinks.
Drinking a lot of alcohol rapidly can cause a blackout-- not being able to remember entire incidents, like what exactly she or he did the night before.
If alcohol injures the hippocampus, a person might find it difficult to learn and to hold on to information.

CEREBELLUM-- The cerebellum is necessary for coordination, ideas, and attention. alcohol addict may have trouble with these abilities when alcohol gets in the cerebellum. After drinking alcohol, a person's hands might be so tremulous that they cannot touch or grab things properly, and they might fail to keep their equilibrium and fall.

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

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

A person might have difficulty with these skills when alcohol goes into the cerebellum. After drinking alcohol, a person's hands might be so shaky that they cannot touch or grab things properly, and they may lose their equilibrium and fall.

After an individual alcoholic beverages alcohol, blood pressure, hunger, thirst, and the urge to urinate increase while body temperature and heart rate decrease.

Alcohol in fact cools down the physical body. Consuming a lot of alcohol outdoors in cold weather conditions can cause an individual's body temperature to drop below normal.
