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

Alcohol can trigger modifications in the architecture and operation of the growing brain, which continues to grow into a person's mid 20s, and it might have consequences reaching far beyond adolescence.

In adolescence, brain growth is defined by remarkable changes to the brain's architecture, neuron connectivity ("electrical wiring"), and physiology. These transformations in the brain alter everything from emerging sexuality to emotions and judgment.

Not all parts of the adolescent brain mature at the same time, which may put an adolescent at a disadvantage in specific circumstances. The limbic regions of the brain mature earlier than the frontal lobes.

Ways Alcohol Disturbs the Human Brain Alcohol alters a juvenile's brain growth in several ways. The results of adolescent alcohol consumption on specific brain activities are summarized below. Alcohol is a central nervous system sedative. Alcohol can seem to be a stimulant because, to begin with, it depresses the portion of the brain that manages inhibitions.

CEREBRAL CORTEX-- Alcohol hampers the cerebral cortex as it works with 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 spinal cord-- sends a signal to that portion of the body. Alcohol reduces the central nervous system, making the person think, speak, and move slower.

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

Once alcohol impairs the frontal lobes of the brain, an individual may find it hard to manage his or her feelings and impulses. The individual might act without thinking or might even become violent. drinking alcohol over a long period of time can damage the frontal lobes forever.

HIPPOCAMPUS-- The hippocampus is the part of the human brain where memories are generated. Once alcohol reaches the hippocampus, an individual might have trouble recalling something she or he 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 trigger a blackout-- not having the ability to recall entire incidents, such as what exactly she or he did the night before. If alcohol injures the hippocampus, an individual might find it hard to learn and to hold on to information.

CEREBELLUM-- The cerebellum is necessary for coordination, thoughts, and awareness. Once alcohol goes into the cerebellum, a person might have trouble with these skills. After drinking alcohol, a person's hands may be so unsteady that they cannot touch or get hold of things properly, and they may lose their balance and tumble.

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

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

A person might have difficulty with these skills once alcohol goes into the cerebellum. After drinking alcohol, an individual's hands might be so tremulous that they can't touch or grab things normally, and they might fail to keep their balance and fall.

After an individual alcoholic beverages alcohol, blood pressure, appetite, being thirsty, and the urge to urinate increase while body temperature and heart rate decline.

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