Alcohol Consumption Can Cause Alterations In The Architecture And Function Of The Growing Brain
Alcohol consumption can trigger alterations in the structure and function of the developing brain, which continues to mature into an individual's mid 20s, and it might have consequences reaching far beyond adolescence.
In adolescence, brain development is characterized by remarkable modifications to the brain's structure, neuron connectivity ("circuitry"), and physiology. These transformations in the brain affect everything from emerging sexuality to emotions and judgment.
Not all parts of the juvenile brain mature at the same time, which might put a juvenile at a disadvantage in specific scenarios. The limbic regions of the brain develop earlier than the frontal lobes.
Ways Alcohol Affects the Brain
Alcohol affects an adolescent's brain development in several ways. The results of underage alcohol consumption on particular brain activities are detailed below.
Alcohol is a central nervous system depressant. Alcohol can seem to be a stimulant because, initially, it suppresses the portion of the brain that controls inhibitions.
CEREBRAL CORTEX-- Alcohol slows down the cerebral cortex as it works with 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 spine-- sends out a signal to that portion of the physical body. Alcohol impedes the central nervous system, making the individual think, communicate, and move more slowly.
FRONTAL LOBES -- The brain's frontal lobes are necessary for advanced planning, creating concepts, making decisions, and using self-control.
A person may find it difficult to control his or her emotions and urges when alcohol impairs the frontal lobes of the brain. The person may act without thinking or might even become violent. Consuming alcohol over an extended period of time can harm the frontal lobes forever.
HIPPOCAMPUS-- The hippocampus is the part of the human brain where memories are created.
Once alcohol gets to the hippocampus, an individual might have difficulty recollecting something she or he just learned, such as a name or a telephone number. This can take place after just one or two alcoholic beverages.
Drinking a great deal of alcohol quickly can trigger a blackout-- not being able to recollect whole happenings, like what she or he did the night before.
If alcohol harms the hippocampus, a person may find it tough to learn and to hold on to knowledge.
CEREBELLUM-- The cerebellum is very important for coordination, ideas, and awareness. Once alcohol enters the cerebellum, an individual might have difficulty with these abilities. After drinking alcohol, a person's hands may be so tremulous that they cannot touch or grab things properly, and they might fail to keep their equilibrium and tumble.
HYPOTHALAMUS-- The hypothalamus is a little part of the brain that does a fantastic number of the body's housekeeping tasks. Alcohol frustrates the operation of the hypothalamus. After an individual drinks alcohol, blood pressure, appetite, being thirsty, and the need to urinate intensify while physical body temperature and heart rate decline.
MEDULLA-- The medulla controls the body's automatic actions, such as an individual's heart beat. It also keeps the physical body at the best temperature level. Alcohol in fact cools down the body. Drinking a great deal of alcohol outdoors in cold weather can cause an individual's physical body temperature to drop below its normal level. This harmful condition is termed hypothermia.
A person may have trouble with these abilities when alcohol enters the cerebellum. After consuming alcohol, a person's hands might be so unsteady that they cannot touch or take hold of things properly, and they may lose their balance and fall.
After an individual drinks alcohol, blood pressure, appetite, being thirsty, 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 can trigger an individual's body temperature to drop below normal.
