Alcohol Consumption Can Cause Changes In The Architecture And Function Of The Blossoming Brain

Alcohol consumption can cause alterations in the architecture and function of the blossoming brain, which continues to grow into an individual's mid 20s, and it may have repercussions reaching far beyond teenage years.

In adolescence, brain development is identified by dramatic modifications to the brain's architecture, neuron connectivity ("electrical wiring"), and physiology. These transformations in the brain alter everything from developing sexuality to emotionality and judgment.

Not all portions of the adolescent brain mature at the same time, which may put a youth at a disadvantage in specific situations. The limbic areas of the brain mature earlier than the frontal lobes. The limbic areas control feelings and are associated with a juvenile's decreased level of 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 decisions or acts and a disregard for consequences.

How Alcohol Disturbs the Brain
Alcohol alters an adolescent's brain development in many ways. The effects of minor alcohol consumption on particular brain activities are discussed below.
Alcohol is a central nervous system depressant. Alcohol can seem to be a stimulant because, before anything else, it suppresses the part of the brain that controls inhibitions.

CORTEX-- Alcohol reduces the cerebral cortex as it processes details from a person'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 part of the physical body. Alcohol hampers the central nervous system, making the person think, converse, and move slower.


FRONTAL LOBES -- The brain's frontal lobes are essential for planning, forming ideas, making decisions, and using self-discipline.

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

HIPPOCAMPUS-- The hippocampus is the part of the brain in which memories are created.
When alcohol gets to the hippocampus, an individual might have difficulty recalling a thing she or he just learned, such as a person's name or a phone number. This can take place after just a couple of alcoholic beverages.
Drinking a great deal of alcohol rapidly can cause a blackout-- not having the ability to recollect whole events, like what exactly he or she did the night before.
A person might find it tough to learn and to hold on to knowledge if alcohol injures the hippocampus.

CEREBELLUM-- The cerebellum is very important for coordination, ideas, and focus. When alcohol goes into the cerebellum, an individual might have difficulty with these skills. After consuming alcohol, a person's hands may be so unsteady that they cannot touch or take hold of things normally, and they might lose their balance and tumble.

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

MEDULLA-- The medulla manages the physical body's automatic actions, such as an individual's heart beat. It likewise keeps the physical body at the right temperature level. Alcohol actually cools down the physical body. Consuming a great deal of alcohol outdoors in chilly climates can trigger a person's body temperature to fall below normal. This unsafe situation is termed hypothermia.

An individual might have difficulty with these abilities once alcohol enters the cerebellum. After drinking alcohol, a person's hands might be so unsteady that they cannot touch or grab things normally, and they may lose their equilibrium and fall.

After a person drinks alcohol, blood pressure, appetite, thirst, and the desire to urinate increase while body temperature levels and heart rate decline.

Alcohol actually chills the physical body. Drinking a lot of alcohol outdoors in cold weather conditions can trigger a person's physical body temperature to drop below normal.
