Alcohol Can Trigger Alterations In The Architecture And Function Of The Blossoming Brain

Alcohol consumption can cause alterations in the structure and operation of the developing brain, which continues to mature into a person's mid 20s, and it might have consequences reaching far beyond adolescence.

In adolescence, brain development is identified by remarkable changes to the brain's structure, neural connections ("electrical wiring"), and physiology. These transformations in the brain alter everything from emerging sexuality to emotions and judgment.

Not all component parts of the adolescent brain mature simultaneously, which may put a youth at a disadvantage in specific circumstances. For example, the limbic regions of the brain develop quicker than the frontal lobes. The limbic regions control feelings and are connected with an adolescent's lowered level of sensitivity to risk. The frontal lobes are accountable for self-control, judgment, reasoning, problem-solving, and impulse control. Differences in maturation among parts of the brain can lead to impulsive choices or acts and a neglect for repercussions.

The way Alcohol Alters the Human Brain Alcohol affects a juvenile's brain growth in several ways. The repercussions of minor alcohol consumption on particular brain activities are detailed below. Alcohol is a central nervous system sedative. Alcohol can appear to be a stimulant because, to begin with, it depresses the part of the human brain that controls inhibitions.

CORTEX-- Alcohol impedes the cerebral cortex as it processes details 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 spinal cord-- sends a signal to that part of the body. Alcohol hampers the central nervous system, making the individual think, communicate, and move less quickly.

FRONTAL LOBES -- The brain's frontal lobes are very important for organizing, creating ideas, making decisions, and exercising self-discipline.

Once alcohol impairs the frontal lobes of the brain, an individual may find it hard to manage his/her feelings and urges. The person may act without thinking or might even get violent. Consuming alcohol over a long period of time can damage the frontal lobes permanently.

HIPPOCAMPUS-- The hippocampus is the part of the brain in which memories are created. When alcohol gets to the hippocampus, a person might have difficulty recalling something he or she just learned, such as a name or a phone number. This can happen after just a couple of alcoholic beverages. Drinking a lot of alcohol rapidly can trigger a blackout-- not being able to recall entire incidents, like what exactly he or she did last night. An individual may find it hard to learn and to hold on to information if alcohol injures the hippocampus.

CEREBELLUM-- The cerebellum is necessary for coordination, ideas, and awareness. A person may have difficulty with these abilities once alcohol goes into the cerebellum. After consuming alcohol, a person's hands might be so tremulous that they cannot touch or get hold of things properly, and they may lose their equilibrium and tumble.

HYPOTHALAMUS-- The hypothalamus is a small part of the brain that does a fantastic variety of the physical body's housekeeping tasks. alcohol upsets the operation of the hypothalamus. After an individual drinks alcohol, blood pressure, appetite, thirst, and the need to urinate increase while body temperature level and heart rate decline.

MEDULLA-- The medulla manages the body's automatic actions, like a person's heart beat. It also keeps the body at the ideal temperature. Alcohol really chills the physical body. Drinking a great deal of alcohol outdoors in chilly climates can cause a person's body temperature level to drop below its normal level. This hazardous condition is knowned as hypothermia.

An individual might have trouble with these abilities when alcohol gets in the cerebellum. After drinking alcohol, a person's hands might be so unsteady that they cannot touch or take hold of things normally, and they may lose their equilibrium and tumble.

After a person alcoholic beverages alcohol, blood pressure, hunger, thirst, and the urge to urinate increase while body temperature levels and heart rate decrease.

Alcohol in fact cools down the body. Consuming a lot of alcohol outdoors in cold weather can cause a person's physical body temperature to drop below normal.
