Alcohol can cause changes in the structure and operation of the growing brain, which continues to mature into an individual's mid 20s, and it may have repercussions reaching far beyond adolescence.

In adolescence, brain development is characterized by dramatic changes to the brain's structure, neuron connectivity ("circuitry"), and physiology. These transformations in the brain alter everything from emerging sexuality to emotionality and cognitive ability.

addiction of the juvenile brain mature simultaneously, which might put an adolescent at a disadvantage in specific scenarios. For instance, the limbic areas of the brain develop quicker than the frontal lobes. The limbic areas manage emotions and are connected with a juvenile's lowered level of 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 result in rash choices or acts and a neglect for consequences.


How Alcohol Alters the Brain
Alcohol alters an adolescent's brain growth in numerous ways. The consequences of adolescent alcohol consumption on particular brain activities are summarized below.
addiction is a central nervous system depressant. Alcohol can appear to be a stimulant because, to begin with, it depresses the part of the human brain that governs inhibitions.

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

CENTRAL NERVOUS SYSTEM-- When a person thinks about something he desires his body to do, the central nervous system-- the brain and the spine-- sends a signal to that part of the body. Alcohol hinders the central nervous system, making the person think, speak, and move more slowly.

FRONTAL LOBES -- The human brain's frontal lobes are necessary for organizing, forming ideas, making decisions, and employing self-control.

Once alcohol impairs the frontal lobes of the human brain, an individual might find it difficult to control his/her feelings and urges. The individual might act without thinking or may even get violent. Drinking alcohol over an extended period of time can harm the frontal lobes permanently.

HIPPOCAMPUS-- The hippocampus is the part of the brain where memories are generated.
Once alcohol gets to the hippocampus, a person might have trouble remembering something she or he just learned, such as a name or a phone number. This can take place after just one or two alcoholic beverages.
Drinking a lot of alcohol quickly can trigger a blackout-- not having the ability to remember whole events, such as what exactly she or he did the night before.
If alcohol injures the hippocampus, an individual might find it difficult to learn and to hold on to information.

CEREBELLUM-- The cerebellum is very important for coordination, ideas, and awareness. Once alcohol enters the cerebellum, an individual might have trouble with these abilities. After drinking alcohol, an individual's hands might be so tremulous that they can't touch or take hold of things normally, and they may lose their balance and fall.

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

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

A person might have trouble with these abilities once alcohol gets in the cerebellum. After drinking alcohol, an individual's hands might be so unsteady that they cannot touch or take hold of things properly, and they might lose their balance and fall.

After an individual drinks alcohol, blood pressure, appetite, thirst, and the urge to urinate increase while physical body temperature and heart rate decline.

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