Alcohol Consumption Can Trigger Alterations In The Structure And Function Of The Growing Brain

Alcohol consumption can trigger alterations in the structure and operation of the growing brain, which continues to develop into an individual's mid 20s, and it might have consequences reaching far beyond adolescence.

In adolescence, brain growth is identified by remarkable modifications to the brain's structure, neural connections ("electrical wiring"), and physiology. These transformations in the brain alter everything from emerging sexuality to emotionality and judgment.

Not all portions of the adolescent brain mature simultaneously, which may put an adolescent at a disadvantage in particular scenarios. The limbic areas of the brain mature earlier than the frontal lobes. The limbic regions control feelings and are connected with an adolescent's reduced sensitivity to risk. The frontal lobes are responsible for self-control, judgment, reasoning, problem-solving, and impulse control. Differences in maturation among parts of the brain can lead to impulsive decisions or actions and a disregard for repercussions.

The way Alcohol Alters the Human Brain Alcohol disturbs an adolescent's brain growth in several ways. The results of underage alcohol consumption on particular brain activities are summarized below. Alcohol is a central nervous system sedative. alcohol can appear to be a stimulant because, at the start, it depresses the portion of the human brain that regulates inhibitions.

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

CENTRAL NERVOUS SYSTEM-- When an individual thinks about something he wants his body to do, the central nervous system-- the brain and the spine-- sends a signal to that portion of the physical body. Alcohol slows down the central nervous system, making the individual think, speak, and move more slowly.

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

A person might find it difficult to manage his or her emotions and urges once alcohol impairs the frontal lobes of the brain. The individual might act without thinking or might even become violent. Drinking alcohol over an extended period of time can harm the frontal lobes forever.

HIPPOCAMPUS-- The hippocampus is the part of the brain in which memories are generated. When alcohol gets to the hippocampus, a person might have trouble recalling a thing she or he just learned, such as a person's name or a phone number. This can occur after just one or two alcoholic beverages. drinking a lot of alcohol rapidly can cause a blackout-- not having the ability to recall entire happenings, like what exactly she or he did the night before. If alcohol harms the hippocampus, a person might find it hard to learn and to hold on to knowledge.

CEREBELLUM-- The cerebellum is very important for coordination, thoughts, and attention. An individual might have trouble with these skills when alcohol goes into the cerebellum. After drinking alcohol, an individual's hands may be so tremulous that they can't touch or get hold of things normally, and they might lose their equilibrium and fall.

HYPOTHALAMUS-- The hypothalamus is a small 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, appetite, being thirsty, and the need to urinate increase while physical body temperature level and heart rate decrease.

MEDULLA-- The medulla controls the physical body's automatic actions, like an individual's heartbeat. It likewise keeps the body at the best temperature. Alcohol really chills the physical body. Consuming a great deal of alcohol outdoors in cold weather can trigger a person's body temperature to drop below its normal level. This harmful condition is called hypothermia.

A person may have trouble with these abilities once alcohol goes into the cerebellum. After consuming alcohol, an individual's hands may be so unsteady that they cannot touch or grab things properly, and they may fail to keep their balance and tumble.

After an individual drinks alcohol, blood pressure, hunger, thirst, and the urge 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 trigger a person's body temperature to fall below normal.
