Alterations In The Growing Brain from Using Alcohol?

Alcohol consumption can trigger changes in the structure and operation of the growing 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 characterized by remarkable modifications to the brain's structure, neural connections ("circuitry"), and physiology. These changes in the brain alter everything from developing sexuality to emotions and judgment.

Not all parts of the adolescent brain mature simultaneously, which may put a juvenile at a disadvantage in certain scenarios. For example, the limbic regions of the brain develop quicker than the frontal lobes. The limbic areas control emotions and are associated with an adolescent's decreased sensitivity to risk. The frontal lobes are responsible for self-control, judgment, reasoning, analytic skills, and impulse control. Differences in maturation among parts of the brain can lead to careless choices or acts and a disregard for repercussions.

The way Alcohol Alters the Brain Alcohol alters an adolescent's brain growth in numerous ways. The consequences of juvenile drinking on particular brain activities are discussed below. Alcohol is a central nervous system sedative drug. Alcohol can seem to be a stimulant because, initially, it suppresses the part of the brain that controls inhibitions.

CEREBRAL CORTEX-- Alcohol reduces the cerebral cortex as it processes information from a person's senses.

CENTRAL NERVOUS SYSTEM-- When a person thinks about something he desires his body to do, the central nervous system-- the brain and the spinal cord-- sends out a signal to that part of the physical body. Alcohol reduces the central nervous system, making the individual think, communicate, and move less quickly.

FRONTAL LOBES -- The human brain's frontal lobes are important for organizing, forming ideas, making decisions, and employing self-control.

An individual may find it difficult to manage his or her emotions and urges once alcohol affects the frontal lobes of the brain. The individual might act without thinking or may 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 human brain in which memories are created. When alcohol gets to the hippocampus, a person may have difficulty remembering a thing he or she just learned, like a name or a telephone number. This can occur after just a couple of alcoholic beverages. drinking a lot of alcohol quickly can cause a blackout-- not having the ability to remember whole happenings, such as what exactly he or she did last night. A person may find it difficult to learn and to hold on to knowledge if alcohol injures the hippocampus.

CEREBELLUM-- The cerebellum is important for coordination, to form thoughts, and focus. A person may have difficulty with these skills once alcohol gets in the cerebellum. After drinking alcohol, a person's hands may be so unsteady that they can't touch or take hold of things properly, and they might fail to keep their equilibrium and fall.

HYPOTHALAMUS-- The hypothalamus is a small part of the brain that does a remarkable number of the physical body's housekeeping tasks. Alcohol frustrates the work of the hypothalamus. After a person drinks alcohol, blood pressure, hunger, being thirsty, and the impulse to urinate intensify while body temperature level and heart rate decline.

MEDULLA-- The medulla manages the body's automatic actions, like a person's heart beat. It likewise keeps the body at the ideal temperature level. Alcohol really cools down the body. Drinking a lot of alcohol outdoors in chilly weather can trigger a person's body temperature to fall below normal. This hazardous condition is termed hypothermia.

An individual might have trouble with these skills once alcohol enters the cerebellum. After consuming alcohol, an individual's hands may be so unsteady that they can't touch or get hold of things normally, and they may fail to keep their balance and fall.

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

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