Alcohol Consumption Can Trigger Changes In The Structure And Function Of The Developing Brain

Alcohol consumption can cause alterations in the architecture and function of the growing brain, which continues to develop into an individual's mid 20s, and it might have repercussions reaching far beyond adolescence.

In adolescence, brain development is identified by remarkable modifications to the brain's structure, neural connections ("circuitry"), and physiology. These transformations in the brain alter everything from developing sexuality to emotionality and cognitive ability.

Not all parts of the adolescent brain mature at the same time, which might put a juvenile at a disadvantage in particular circumstances. The limbic areas of the brain mature earlier than the frontal lobes.

The way Alcohol Affects the Brain
Alcohol alters a juvenile's brain growth in numerous ways. The results of adolescent drinking on specialized brain functions are summarized below.
Alcohol is a central nervous system sedative drug. alcohol addict can seem to be a stimulant because, at the start, it depresses the portion of the human brain that manages inhibitions.

CEREBRAL CORTEX-- Alcohol slows down the cerebral cortex as it works with details from an individual's senses.

CENTRAL NERVOUS SYSTEM-- When an individual thinks of something he desires his body to undertake, the central nervous system-- the brain and the spine-- sends a signal to that portion of the body. Alcohol reduces the central nervous system, making the individual think, converse, and move more slowly.

FRONTAL LOBES -- The brain's frontal lobes are very important for advanced planning, forming ideas, decision making, and employing self-control.

An individual may find it tough to control his or her feelings and urges once alcohol affects the frontal lobes of the brain. The person may act without thinking or may even get violent. Consuming alcohol over an extended period of time can harm the frontal lobes forever.

HIPPOCAMPUS-- The hippocampus is the part of the human brain in which memories are made.
When alcohol gets to the hippocampus, a person might have difficulty remembering something she or he just learned, such as a name or a telephone number. This can happen after just a couple of drinks.
Drinking a great deal of alcohol quickly can trigger a blackout-- not being able to recollect entire incidents, such as what he or she did last night.
If alcohol injures the hippocampus, an individual may find it tough to learn and to hold on to knowledge.

CEREBELLUM-- The cerebellum is necessary for coordination, to form thoughts, and attention. Once alcohol gets in the cerebellum, a person may have difficulty with these abilities. After consuming alcohol, a person's hands might be so shaky that they cannot touch or get hold of things properly, and they might fail to keep their equilibrium and fall.

HYPOTHALAMUS-- The hypothalamus is a little part of the brain that does a remarkable variety of the body's housekeeping chores. Alcohol upsets the work of the hypothalamus. After an individual consumes alcohol, blood pressure, hunger, being thirsty, and the impulse to urinate intensify while physical body temperature and heart rate decrease.

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

An individual might have trouble with these skills once alcohol gets in the cerebellum. After drinking alcohol, a person's hands might be so unsteady that they can't touch or take hold of things properly, 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 and heart rate decline.

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