Alcohol Consumption Can Trigger Changes In The Operation Of The Growing Brain

Alcohol consumption can cause changes in the structure and operation 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 growth is characterized by dramatic modifications to the brain's structure, neural connections ("electrical wiring"), and physiology. These changes in the brain alter everything from emerging sexuality to emotions and judgment.

Not all parts of the adolescent brain mature at the exact same time, which might put a juvenile at a disadvantage in specific situations. The limbic areas of the brain develop sooner than the frontal lobes.

The way Alcohol Disturbs the Human Brain Alcohol alters an adolescent's brain development in several ways. The results of adolescent alcohol consumption on specific brain activities are detailed below. Alcohol is a central nervous system depressant. Alcohol can seem to be a stimulant because, to begin with, it depresses the part of the human brain that manages inhibitions.

CEREBRAL CORTEX-- Alcohol impedes the cerebral cortex as it works with details from a person's senses.

CENTRAL NERVOUS SYSTEM-- When an individual thinks of something he wants his body to undertake, the central nervous system-- the brain and the spine-- sends out a signal to that part of the body. Alcohol impedes the central nervous system, making the person think, speak, and move less quickly.

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

A person might find it difficult to manage his or her emotions and urges when alcohol impacts the frontal lobes of the brain. The person may act without thinking or might even become violent. Drinking alcohol over a long period of time can damage the frontal lobes forever.

HIPPOCAMPUS-- The hippocampus is the part of the brain where memories are generated. When alcohol reaches the hippocampus, an individual might have difficulty recalling something she or he just learned, like a person's name or a telephone number. This can occur after just one or two alcoholic beverages. Drinking a great deal of alcohol quickly can trigger a blackout-- not having the ability to remember whole occurrences, like what exactly he or she did last night. An individual may find it difficult to learn and to hold on to knowledge if alcohol harms the hippocampus.

CEREBELLUM-- The cerebellum is very important for coordination, thoughts, and awareness. Once alcohol gets in the cerebellum, an individual might have difficulty with these skills. After consuming alcohol, an individual's hands may be so unsteady that they can't touch or get hold of things normally, and they may lose their equilibrium and fall.

HYPOTHALAMUS-- The hypothalamus is a little part of the brain that does a remarkable variety 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 need to urinate increase while physical body temperature and heart rate decline.

MEDULLA-- The medulla manages the physical body's automatic actions, like a person's heartbeat. It likewise keeps the body at the best temperature level. Alcohol in fact cools down the physical body. drinking a great deal of alcohol outdoors in chilly weather can cause a person's body temperature to drop below normal. This hazardous situation is termed hypothermia.

A person might have difficulty with these abilities once alcohol goes into the cerebellum. After consuming alcohol, an individual's hands might be so unsteady that they cannot touch or take hold of things normally, and they might lose their equilibrium and tumble.

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

Alcohol in fact chills the physical body. Consuming a lot of alcohol outdoors in cold weather conditions can trigger an individual's physical body temperature level to fall below normal.
