Alcohol Use Can Trigger Alterations In The Blossoming BrainAlcohol can trigger alterations in the architecture and function of the developing brain, which continues to mature into an individual's mid 20s, and it might have repercussions reaching far beyond adolescence.

In adolescence, brain growth 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 emotions and judgment.

Not all parts of the adolescent brain mature at the same time, which may put an adolescent at a disadvantage in certain circumstances. The limbic regions of the brain develop earlier than the frontal lobes.
Ways Alcohol Disturbs the Brain Alcohol disturbs a juvenile's brain development in numerous ways. The effects of minor alcohol consumption on particular brain activities are discussed below. Alcohol is a central nervous system sedative drug. Alcohol can appear to be a stimulant because, before anything else, it depresses the part of the human brain that regulates inhibitions.
CEREBRAL CORTEX-- Alcohol hinders the cerebral cortex as it works with information 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 impedes the central nervous system, making the person think, converse, 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.
When alcohol impacts the frontal lobes of the brain, an individual may find it difficult to control his or her emotions and urges. The person might act without thinking or might even get violent. Consuming alcohol over a long period of time can harm the frontal lobes forever.
HIPPOCAMPUS-- The hippocampus is the part of the human brain where memories are created. When alcohol gets to the hippocampus, a person might have trouble remembering something she or he just learned, like a person's name or a telephone number. This can occur after just a couple of alcoholic beverages. Drinking a lot of alcohol quickly can trigger a blackout-- not being able to remember entire happenings, such as what exactly he or she did last night. If alcohol harms the hippocampus, a person might find it hard to learn and to hang on to information.
CEREBELLUM-- The cerebellum is important for coordination, to form thoughts, and awareness. Once alcohol enters the cerebellum, an individual might have difficulty with these abilities. After consuming alcohol, an individual's hands might be so shaky that they cannot touch or take hold of things normally, and they might fail to keep their balance and tumble.
HYPOTHALAMUS-- The hypothalamus is a little part of the brain that does a fantastic variety of the physical body's housekeeping tasks. Alcohol frustrates the work of the hypothalamus. After a person consumes alcohol, blood pressure, hunger, thirst, and the impulse to urinate intensify while physical body temperature and heart rate decrease.
MEDULLA-- The medulla controls the body's unconscious actions, like an individual's heart beat. It also keeps the physical body at the right temperature. Alcohol in fact cools down the physical body. Consuming a lot of alcohol outdoors in chilly weather can trigger an individual's physical body temperature to fall below normal. This hazardous situation is knowned as 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 can't touch or take hold of things normally, and they may fail to keep their balance and tumble.
After an individual alcoholic beverages alcohol, blood pressure, appetite, being thirsty, and the urge to urinate increase while physical body temperature and heart rate decline.
