Alcohol Consumption Can Trigger Modifications In The Architecture And Function Of The Growing Brain

Alcohol can cause modifications in the architecture and function of the growing brain, which continues to grow into an individual's mid 20s, and it may have consequences reaching far beyond teenage years.

In adolescence, brain development is defined by dramatic changes to the brain's structure, neural connections ("electrical wiring"), and physiology. These transformations in the brain alter everything from emerging sexuality to emotionality and cognitive ability.

Not all parts of the juvenile brain mature at the exact same time, which might put an adolescent at a disadvantage in specific situations. The limbic regions of the brain develop earlier than the frontal lobes.

The way Alcohol Affects the Human Brain Alcohol alters an adolescent's brain growth in numerous ways. The results of adolescent drinking 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 suppresses the part of the brain that governs inhibitions.

CORTEX-- Alcohol hampers the cortex as it processes details 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 spine-- sends out a signal to that portion of the body. alcohol slows down the central nervous system, making the person think, converse, and move less quickly.

FRONTAL LOBES -- The brain's frontal lobes are essential for organizing, forming concepts, decision making, and employing self-discipline.

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

HIPPOCAMPUS-- The hippocampus is the portion of the human brain in which memories are generated. Once alcohol gets to the hippocampus, a person might have difficulty recalling something she or he just learned, such as a person's name or a telephone number. This can take place after just a couple of drinks. Drinking a great deal of alcohol rapidly can trigger a blackout-- not having the ability to recall whole incidents, such as what exactly she or he did the night before. If alcohol harms the hippocampus, a person may find it hard to learn and to hold on to knowledge.

CEREBELLUM-- The cerebellum is essential for coordination, thoughts, and focus. Once alcohol goes into the cerebellum, a person might have difficulty with these abilities. After drinking alcohol, an individual's hands may be so unsteady that they can't touch or get hold of things properly, and they may lose their balance and fall.

HYPOTHALAMUS-- The hypothalamus is a small part of the brain that does an amazing number of the physical body's housekeeping chores. Alcohol frustrates the operation of the hypothalamus. After an individual drinks alcohol, blood pressure, hunger, thirst, and the impulse to urinate intensify while physical body temperature and heart rate decline.

MEDULLA-- The medulla manages the body's unconscious actions, like an individual's heartbeat. It likewise keeps the body at the ideal temperature. Alcohol really cools down the body. Drinking a lot of alcohol outdoors in chilly weather can cause a person's body temperature level to drop below normal. This harmful situation is called hypothermia.

A person may have trouble with these skills when alcohol enters the cerebellum. After drinking alcohol, a person's hands might be so tremulous that they can't touch or grab things properly, and they might lose their equilibrium and tumble.

After a person drinks alcohol, blood pressure, appetite, thirst, and the urge to urinate increase while physical body temperature and heart rate decrease.

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