Alcohol Consumption Can Cause Changes In The Structure And Function Of The Growing Brain

Alcohol consumption can trigger changes in the structure and operation of the blossoming brain, which continues to mature into a person's mid 20s, and it may have repercussions reaching far beyond teenage years.

In adolescence, brain development is identified by remarkable changes to the brain's architecture, neural connections ("electrical wiring"), and physiology. These transformations in the brain disturb everything from developing sexuality to emotionality and cognitive ability.

Not all parts of the juvenile brain mature simultaneously, which might put an adolescent at a disadvantage in certain situations. For example, the limbic areas of the brain mature earlier than the frontal lobes. The limbic regions regulate emotions and are associated with a juvenile's decreased sensitivity to risk. The frontal lobes are responsible for self-regulation, judgment, reasoning, problem-solving, and impulse control. Differences in maturation among parts of the brain can result in rash choices or acts and a neglect for consequences.

Ways Alcohol Disturbs the Human Brain
Alcohol affects a juvenile's brain growth in many ways. The consequences of adolescent drinking on particular brain activities are explained below.
Alcohol is a central nervous system sedative drug. Alcohol can seem to be a stimulant because, initially, it suppresses the part of the human brain that regulates inhibitions.

CORTEX-- Alcohol impedes the cortex as it works with information from an individual'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 out a signal to that portion of the physical body. Alcohol slows down the central nervous system, making the person think, speak, and move slower.

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

Once alcohol impairs the frontal lobes of the human brain, a person might find it difficult to control his or her feelings and urges. The individual might act without thinking or might even become violent. Consuming alcohol over a long period of time can harm the frontal lobes forever.

HIPPOCAMPUS-- The hippocampus is the portion of the human brain where memories are generated.
Once alcohol reaches the hippocampus, an individual might have trouble recalling a thing he or she just learned, like a name or a phone number. This can happen after just a couple of drinks.
Drinking alcohol addiction of alcohol rapidly can cause a blackout-- not having the ability to recall whole happenings, such as what exactly he or she did last night.
A person might find it tough to learn and to hold on to knowledge if alcohol injures the hippocampus.

CEREBELLUM-- The cerebellum is important for coordination, ideas, and focus. A person might have trouble with these abilities when alcohol enters 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 balance and fall.

HYPOTHALAMUS-- The hypothalamus is a small part of the brain that does a fantastic number of the body's housekeeping chores. Alcohol frustrates the operation of the hypothalamus. After an individual drinks alcohol, blood pressure, appetite, being thirsty, and the urge to urinate increase while body temperature and heart rate decline.

Alcohol in fact chills the physical body. Consuming a lot of alcohol outdoors in cold weather can cause an individual's body temperature to fall below normal.

An individual may have difficulty with these skills when alcohol goes into the cerebellum. After drinking alcohol, a person's hands may be so tremulous that they can't touch or take hold of things normally, and they may fail to keep their balance and tumble.

After an individual alcoholic beverages alcohol, blood pressure, appetite, thirst, and the desire to urinate increase while body temperature levels and heart rate decrease.
