Alcohol consumption can trigger modifications in the structure and operation of the blossoming brain, which continues to grow into an individual's mid 20s, and it may have repercussions reaching far beyond adolescence.
In adolescence, brain growth is identified by dramatic modifications to the brain's architecture, neural connections ("electrical wiring"), and physiology. These transformations in the brain disturb everything from emerging sexuality to emotionality and judgment.
Not all parts of the adolescent brain mature at the same time, which might put an adolescent at a disadvantage in specific situations. The limbic areas of the brain mature sooner than the frontal lobes.
The way Alcohol Alters the Human Brain
Alcohol disturbs an adolescent's brain growth in numerous ways. The effects of adolescent drinking on specific brain activities are discussed below.
Alcohol is a central nervous system depressant. Alcohol can appear to be a stimulant because, before anything else, it depresses the portion of the brain that manages inhibitions.
CORTEX-- Alcohol impedes the cortex as it processes details from a person's senses.
CENTRAL NERVOUS SYSTEM-- When an individual thinks about something he wants his body to do, the central nervous system-- the brain and the spine-- sends out a signal to that portion of the body. Alcohol hampers the central nervous system, making the person think, converse, and move more slowly.
FRONTAL hangover -- The human brain's frontal lobes are very important for planning, forming ideas, decision making, and using self-discipline.
A person may find it hard to manage his or her emotions and urges when alcohol impairs the frontal lobes of the brain. The person may act without thinking or may even get violent. Consuming alcohol addict over an extended period of time can damage the frontal lobes forever.
HIPPOCAMPUS-- The hippocampus is the part of the human brain where memories are created.
Once alcohol reaches the hippocampus, an individual may have difficulty remembering something she or he just learned, such as a name or a telephone number. This can happen after just one or two alcoholic beverages.
Drinking a great deal of alcohol quickly can trigger a blackout-- not having the ability to remember whole incidents, such as what exactly he or she did the night before.
If alcohol harms the hippocampus, an individual might find it difficult to learn and to hang on to information.
CEREBELLUM-- alcohol dependence is very important for coordination, ideas, and attention. When alcoholism gets in the cerebellum, an individual may have trouble with these skills. After consuming addict , a person's hands might be so tremulous that they cannot touch or grab things normally, and they might fail to keep their equilibrium and fall.
HYPOTHALAMUS-- The hypothalamus is a little part of the brain that does a remarkable number of the body's housekeeping chores. Alcohol upsets the work of the hypothalamus. After a person consumes alcohol, blood pressure, hunger, thirst, and the need to urinate increase while physical body temperature level and heart rate decline.
MEDULLA-- The medulla controls the physical body's unconscious actions, like a person's heart beat. alcoholism keeps the physical body at the right temperature level. Alcohol in fact chills the physical body. Drinking a lot of alcohol outdoors in chilly climates can trigger an individual's physical body temperature level to drop below normal. addicted is called hypothermia.
An individual may have trouble with these skills when alcohol goes into the cerebellum. After drinking alcohol , an individual's hands might be so tremulous that they cannot touch or take hold of things properly, and they might fail to keep their balance and fall.
After an individual alcoholic beverages alcohol, blood pressure, appetite, being thirsty, and the urge to urinate increase while physical body temperature levels and heart rate decrease.
Alcohol in fact cools down the physical body. Drinking a lot of alcohol outdoors in cold weather conditions can cause an individual's body temperature to fall below normal.
