Alcohol consumption can trigger changes in the structure and function of the blossoming brain, which continues to develop into a person's mid 20s, and it might have repercussions reaching far beyond adolescence.
In adolescence, brain development is identified by dramatic changes to the brain's structure, neuron connectivity ("circuitry"), and physiology. alcoholism in the brain affect everything from developing sexuality to emotionality and judgment.
Not all parts of the juvenile brain mature at the exact same time, which may put an adolescent at a disadvantage in certain situations. addictions of the brain develop earlier than the frontal lobes.
Ways Alcohol Affects the Brain
Alcohol alters an adolescent's brain development in several ways. The results of minor alcohol consumption on particular brain functions are discussed below.
addictions is a central nervous system sedative drug. Alcohol can seem to be a stimulant because, to begin with, it depresses the portion of the brain that controls inhibitions.
CORTEX-- Alcohol hampers the cortex as it works with information from a person's senses.
CENTRAL NERVOUS SYSTEM-- When a person thinks of something he desires his body to do, the central nervous system-- the brain and the spine-- sends out a signal to that part of the physical 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 important for advanced planning, forming concepts, decision making, and employing self-discipline.
Once alcohol impacts the frontal lobes of the human brain, a person may find it tough to control his or her feelings and impulses. The person 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 portion of the brain where memories are generated.
When alcoholism reaches the hippocampus, an individual might have difficulty remembering a thing she or he just learned, like a person's name or a phone number. This can occur after just a couple of drinks.
Drinking a great deal of alcohol rapidly can trigger a blackout-- not being able to recall whole occurrences, like what he or she did last night.
An individual might find it difficult to learn and to hold on to information if alcohol harms the hippocampus.
CEREBELLUM-- The cerebellum is important for coordination, ideas, and awareness. When alcohol goes into the cerebellum, an individual may have difficulty with these skills. After drinking alcohol, a person's hands might be so unsteady that they cannot touch or take hold of things normally, and they may fail to keep their equilibrium and fall.
HYPOTHALAMUS-- The hypothalamus is a little part of the brain that does an incredible number of the physical body's housekeeping chores. Alcohol upsets the operation of the hypothalamus. After a person consumes alcohol, blood pressure, appetite, thirst, and the urge to urinate intensify while body temperature and heart rate decline.
Alcohol actually cools down the physical body. Consuming a lot of alcohol outdoors in cold weather conditions can trigger an individual's body temperature level to drop below normal.
An individual may have difficulty with these abilities when alcohol goes into the cerebellum. After consuming alcohol, an individual's hands might be so unsteady that they can't touch or grab things normally, and they may lose their balance and fall.
After a person alcoholic beverages alcohol, blood pressure, hunger, being thirsty, and the urge to urinate increase while body temperature and heart rate decline.
Alcohol in fact cools down the body. Consuming a lot of alcohol outdoors in cold weather can trigger an individual's body temperature to fall below normal.
