Alcohol Can Trigger Changes In The Architecture And Operation Of The Developing Brain
Alcohol consumption can cause modifications in the structure and operation of the developing brain, which continues to grow into an individual's mid 20s, and it may have repercussions reaching far beyond teenage years.
In adolescence, brain growth is defined by remarkable modifications to the brain's structure, neural connections ("circuitry"), and physiology. These changes in the brain affect everything from emerging sexuality to emotionality and cognitive ability.
Not all portions of the juvenile brain mature concurrently, which might put an adolescent at a disadvantage in particular circumstances. The limbic areas of the brain mature earlier than the frontal lobes. The limbic areas control feelings and are related to an adolescent's lowered sensitivity to risk. The frontal lobes are responsible for self-control, judgment, reasoning, analytic skills, and impulse control. Variations in maturation among parts of the brain can lead to careless decisions or actions and a disregard for repercussions.
How Alcohol Alters the Brain
Alcohol affects a juvenile's brain development in numerous ways. The effects of underage alcohol consumption on particular brain functions are discussed below.
Alcohol is a central nervous system depressant. Alcohol can seem to be a stimulant because, initially, it depresses the portion of the brain that regulates inhibitions.
CEREBRAL CORTEX-- Alcohol reduces the cerebral cortex as it works with information from a person's senses.
CENTRAL NERVOUS SYSTEM-- When an individual thinks of something he wants his body to undertake, the central nervous system-- the brain and the spinal cord-- sends a signal to that portion of the body. Alcohol hampers the central nervous system, making the person think, communicate, and move more slowly.
FRONTAL LOBES -- The brain's frontal lobes are essential for advanced planning, creating ideas, making decisions, and exercising self-discipline.
An individual might find it hard to control his or her emotions and urges when alcohol impairs the frontal lobes of the brain. The individual may act without thinking or may even get violent. Drinking alcohol over an extended period of time can injure the frontal lobes permanently.
HIPPOCAMPUS-- The hippocampus is the part of the brain where memories are created.
Once alcohol reaches the hippocampus, an individual might have trouble recollecting a thing he or she just learned, such as a 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 having the ability to recollect whole events, such as what exactly he or she did the night before.
An individual might find it hard to learn and to hold on to information if alcohol injures the hippocampus.
CEREBELLUM-- The cerebellum is essential for coordination, to form thoughts, and attention. An individual might have difficulty with these abilities when alcohol enters the cerebellum. After drinking alcohol, an individual's hands may be so unsteady that they cannot touch or get hold of things properly, and they may lose their balance and tumble.
HYPOTHALAMUS-- The hypothalamus is a little part of the brain that does an amazing variety of the body's housekeeping tasks. Alcohol upsets the work of the hypothalamus. After a person drinks alcohol, blood pressure, appetite, thirst, and the need to urinate intensify while physical body temperature and heart rate decrease.
Alcohol actually chills the physical body. Drinking a lot of alcohol outdoors in cold weather conditions can cause an individual's body temperature level to fall below normal.
A person might have trouble with these abilities once alcohol gets in the cerebellum. After drinking alcohol, an individual's hands may be so tremulous that they cannot touch or grab things properly, and they might lose their balance and fall.
After a person alcoholic beverages alcohol, blood pressure, appetite, being thirsty, and the desire to urinate increase while physical body temperature levels and heart rate decrease.
