Alcohol can cause changes in the structure and function of the growing brain, which continues to develop into an individual's mid 20s, and it may have repercussions reaching far beyond adolescence.
In adolescence, brain development is identified by dramatic modifications to the brain's structure, neural connections ("electrical wiring"), and physiology. These transformations in the brain disturb everything from emerging 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 regions of the brain mature earlier than the frontal lobes.
The way Alcohol Alters the Brain Alcohol alters a juvenile's brain development in many ways. The results of adolescent alcohol consumption on particular brain activities are explained below. Alcohol is a central nervous system depressant. Alcohol can appear to be a stimulant because, to begin with, it depresses the portion of the brain that manages inhibitions.
CEREBRAL CORTEX-- Alcohol hinders the cortex as it processes details from a person's senses.
CENTRAL NERVOUS SYSTEM-- When a person thinks of something he desires his body to undertake, the central nervous system-- the brain and the spinal cord-- sends out a signal to that portion of the body. Alcohol hinders the central nervous system, making the person think, speak, and move less quickly.
FRONTAL LOBES -- The human brain's frontal lobes are essential for organizing, forming ideas, making decisions, and employing self-discipline.
A person may find it hard to manage his or her feelings and urges once alcohol impacts the frontal lobes of the brain. The individual may act without thinking or might even become violent. drinking alcohol over an extended period of time can harm the frontal lobes permanently.
HIPPOCAMPUS-- The hippocampus is the part of the human brain in which memories are created. When alcohol reaches the hippocampus, an individual might have trouble recollecting something he or she just learned, like a person's name or a phone number. This can occur after just one or two alcoholic beverages. Drinking a great deal of alcohol rapidly can cause a blackout-- not being able to remember whole events, like what he or she did the night before. A person may find it hard to learn and to hold on to information if alcohol injures the hippocampus.
CEREBELLUM-- The cerebellum is important for coordination, to form thoughts, and attention. When alcohol goes into the cerebellum, a person may have trouble with these skills. After drinking alcohol, an individual's hands may be so tremulous that they can't touch or take hold of things properly, and they might lose their balance and tumble.
HYPOTHALAMUS-- The hypothalamus is a little part of the brain that does a remarkable variety of the physical body's housekeeping tasks. Alcohol upsets the work of the hypothalamus. After a person consumes alcohol, blood pressure, appetite, being thirsty, and the need to urinate intensify while body temperature and heart rate decrease.
Alcohol actually chills 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 may have trouble with these abilities when alcohol gets in the cerebellum. After drinking alcohol, a person's hands may be so unsteady that they cannot touch or get hold of things normally, and they may fail to keep their equilibrium and fall.
After an individual alcoholic beverages alcohol, blood pressure, appetite, thirst, and the urge to urinate increase while body temperature and heart rate decrease.
Alcohol in fact cools down the physical body. Consuming a lot of alcohol outdoors in cold weather conditions can trigger a person's body temperature level to fall below normal.
