Alcohol Can Trigger Changes In The Architecture And Function Of The Growing Brain
Alcohol can cause changes in the structure and operation of the developing 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 characterized by remarkable modifications to the brain's structure, neuron connectivity ("electrical wiring"), and physiology. These transformations in the brain affect everything from emerging sexuality to emotionality and judgment.
Not all parts of the adolescent brain mature concurrently, which might put an adolescent at a disadvantage in certain situations. For example, the limbic regions of the brain develop quicker than the frontal lobes. The limbic regions regulate emotions and are related to a juvenile's reduced sensitivity to risk. The frontal lobes are responsible for self-regulation, judgment, reasoning, problem-solving, and impulse control. Variations in maturation among parts of the brain can result in careless choices or actions and a neglect for consequences.
How Alcohol Disturbs the Brain
Alcohol alters an adolescent's brain growth in many ways. The repercussions of adolescent drinking on specialized brain activities are explained below.
Alcohol is a central nervous system sedative. Alcohol can seem to be a stimulant because, before anything else, it depresses the part of the human brain that controls inhibitions.
CEREBRAL CORTEX-- Alcohol impedes the cortex as it processes information from an individual's senses.
CENTRAL NERVOUS SYSTEM-- When an individual thinks about something he desires his body to undertake, the central nervous system-- the brain and the spinal cord-- sends a signal to that portion of the physical body. Alcohol slows down the central nervous system, making the person think, communicate, and move more slowly.

FRONTAL LOBES -- The brain's frontal lobes are important for organizing, forming ideas, making decisions, and using self-discipline.
When alcohol impairs the frontal lobes of the human brain, a person may find it difficult to manage his or her feelings and urges. The individual may act without thinking or might even become violent. Drinking alcohol over a long period of time can injure the frontal lobes forever.
HIPPOCAMPUS-- The hippocampus is the portion of the brain in which memories are created.
When alcohol reaches the hippocampus, a person might have difficulty recollecting a thing she or he just learned, such as a person's name or a phone number. This can happen after just one or two alcoholic -family-member-while-growing-up./">addiction -to-alcohol">alcoholic beverages.
Drinking a great deal of alcohol quickly can trigger a blackout-- not being able to recollect entire events, like what she or he did the night before.
If alcohol harms the hippocampus, a person may find it difficult to learn and to hold on to knowledge.
CEREBELLUM-- The cerebellum is very important for coordination, to form thoughts, and focus. Once alcohol gets in the cerebellum, a person might have difficulty with these skills. After drinking alcohol, a person's hands may be so unsteady that they cannot touch or grab things normally, and they might lose their equilibrium and tumble.
HYPOTHALAMUS-- The hypothalamus is a small part of the brain that does an incredible variety of the body's housekeeping tasks. Alcohol frustrates the work of the hypothalamus. After an individual drinks alcohol, blood pressure, appetite, thirst, and the need to urinate increase while body temperature level and heart rate decline.
MEDULLA-- The medulla manages the body's unconscious actions, such as a person's heart beat. It also keeps the physical body at the best temperature. Alcohol actually cools down the body. Consuming a great deal of alcohol outdoors in cold climates can cause a person's physical body temperature to drop below normal. This harmful situation is knowned as hypothermia.
An individual may have trouble with these skills once alcohol enters the cerebellum. After drinking alcohol, an individual's hands might be so unsteady that they can't touch or grab things properly, and they may fail to keep their equilibrium and fall.
After an individual drinks alcohol, blood pressure, hunger, thirst, and the desire to urinate increase while body temperature levels and heart rate decrease.
