Alcohol Can Trigger Changes In The Architecture And Operation Of The Growing Brain

Alcohol can cause modifications in the architecture and operation of the blossoming brain, which continues to mature into a person's mid 20s, and it may have repercussions reaching far beyond adolescence.

In adolescence, brain development is identified by dramatic changes to the brain's architecture, neural connections ("circuitry"), and physiology. These transformations in the brain disturb everything from emerging sexuality to emotions and cognitive ability.

Not all component parts of the adolescent brain mature at the same time, which might put a juvenile at a disadvantage in certain circumstances. alcoholism of the brain mature earlier than the frontal lobes. The limbic areas manage feelings and are associated with a juvenile's decreased sensitivity to risk. The frontal lobes are accountable for self-control, judgment, reasoning, analytic skills, and impulse control. Differences in maturation amongst parts of the brain can result in careless choices or acts and a neglect for repercussions.

Ways Alcohol Alters the Human Brain
Alcohol alters an adolescent's brain development in several ways. The consequences of adolescent alcohol consumption on particular brain functions are discussed below.
Alcohol is a central nervous system depressant. Alcohol can appear to be a stimulant because, at the start, it depresses the part of the human brain that controls inhibitions.

CEREBRAL CORTEX-- Alcohol impedes the cortex as it works with information from a person's senses.

CENTRAL NERVOUS SYSTEM-- When a person thinks of something he wants his body to do, the central nervous system-- the brain and the spine-- sends a signal to that portion of the body. Alcohol reduces the central nervous system, making the person think, converse, and move less quickly.

FRONTAL LOBES -- The human brain's frontal lobes are important for advanced planning, forming concepts, decision making, and exercising self-discipline.

A person may find it difficult to control his or her emotions and urges when alcohol affects the frontal lobes of the brain. The person may act without thinking or might even become violent. Consuming alcohol over an extended period of time can damage the frontal lobes forever.

HIPPOCAMPUS-- The hippocampus is the part of the human brain in which memories are generated.
When alcohol reaches the hippocampus, an individual might have difficulty recalling a thing she or he just learned, such as a person's name or a phone number. This can take place after just one or two drinking -what-is-it">alcoholic beverages.
Drinking a great deal of alcohol rapidly can trigger a blackout-- not being able to remember whole occurrences, such as what exactly she or he did the night before.
If alcohol damages the hippocampus, an individual might find it difficult to learn and to hang on to knowledge.

CEREBELLUM-- The cerebellum is important for coordination, ideas, and focus. alcoholism may have difficulty with these skills when alcohol goes into the cerebellum. After consuming alcohol, an individual's hands may be so unsteady that they cannot touch or grab things properly, and they might lose their equilibrium and fall.

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

MEDULLA-- The medulla manages the physical body's unconscious actions, such as a person's heartbeat. It also keeps the physical body at the ideal temperature. Alcohol in fact chills the body. Consuming a great deal of alcohol outdoors in cold weather can cause a person's physical body temperature to drop below normal. This dangerous situation is knowned as hypothermia.

An individual might have trouble with these skills when alcohol gets in the cerebellum. After consuming alcohol, a person's hands may be so tremulous that they cannot touch or grab things properly, and they might lose their equilibrium and tumble.

After a person drinking -alcohol-as-a-social-lubricant"> alcoholic beverages alcohol, blood pressure, hunger, thirst, and the urge to urinate increase while body temperature levels and heart rate decline.

Alcohol actually chills the physical body. Drinking a lot of alcohol outdoors in cold weather conditions can cause a person's body temperature level to drop below normal.
