Alterations In The Blossoming Brain from Alcohol Consumption?

Alcohol can cause modifications in the structure and function of the blossoming brain, which continues to develop into an individual's mid 20s, and it might have repercussions reaching far beyond adolescence.

In adolescence, brain development is defined by dramatic modifications to the brain's structure, neuron connectivity ("electrical wiring"), and physiology. These transformations in the brain alter everything from emerging sexuality to emotionality and judgment.

Not all portions of the adolescent brain mature simultaneously, which might put an adolescent at a disadvantage in particular circumstances. The limbic areas of the brain mature earlier than the frontal lobes. The limbic regions control emotions and are associated with a juvenile's reduced sensitivity to risk. The frontal lobes are accountable for self-control, judgment, reasoning, analytic skills, and impulse control. Variations in maturation among parts of the brain can result in rash choices or actions and a disregard for consequences.

The way Alcohol Disturbs the Brain Alcohol affects a juvenile's brain development in numerous ways. The results of minor drinking on specific brain functions are detailed below. Alcohol is a central nervous system sedative drug. Alcohol can seem to be a stimulant because, initially, it depresses the portion of the brain that regulates inhibitions.

CEREBRAL CORTEX-- Alcohol hinders 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 spinal cord-- sends out a signal to that part of the body. Alcohol impedes the central nervous system, making the individual think, speak, and move less quickly.

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

An individual may find it tough to control his or her emotions and urges once alcohol impacts the frontal lobes of the brain. The individual may act without thinking or might even become violent. Drinking alcohol over a long period of time can damage the frontal lobes permanently.

HIPPOCAMPUS-- The hippocampus is the part of the human brain in which memories are created. Once alcohol reaches the hippocampus, an individual may have trouble remembering a thing she or he just learned, like a name or a phone number. This can occur after just one or two drinks. Drinking a lot of alcohol rapidly can cause a blackout-- not being able to recall whole happenings, such as what exactly he or she did the night before. A person might find it difficult to learn and to hold on to information if alcohol damages the hippocampus.

CEREBELLUM-- The cerebellum is necessary for coordination, ideas, and attention. A person might have trouble with these skills once alcohol gets in the cerebellum. After drinking alcohol, a person's hands might be so shaky that they cannot touch or get hold of things properly, and they might lose their balance and fall.

HYPOTHALAMUS-- The hypothalamus is a small part of the brain that does an amazing variety of the body's housekeeping tasks. Alcohol upsets the operation of the hypothalamus. After an individual drinks alcohol, blood pressure, hunger, thirst, and the impulse to urinate increase while body temperature level and heart rate decrease.

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

A person might have trouble with these abilities when alcohol enters the cerebellum. After consuming alcohol, an individual's hands may be so tremulous that they cannot touch or take hold of things properly, and they might lose their equilibrium and tumble.

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

Alcohol actually cools down the body. Consuming a lot of alcohol outdoors in cold weather can trigger an individual's body temperature level to fall below normal.
