Alcohol Consumption Can Trigger Modifications In The Architecture And Operation Of The Blossoming Brain

alcohol consumption can cause changes in the structure and operation of the developing brain, which continues to develop into an individual's mid 20s, and it may have repercussions reaching far beyond adolescence.

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

Not all portions of the juvenile brain mature concurrently, which may put an adolescent at a disadvantage in certain circumstances. The limbic regions of the brain mature earlier than the frontal lobes. The limbic regions control feelings and are associated with an adolescent's reduced level of sensitivity to risk. The frontal lobes are accountable for self-regulation, judgment, reasoning, problem-solving, and impulse control. Differences in maturation among parts of the brain can result in rash decisions or acts and a disregard for consequences.

The way Alcohol Affects the Human Brain Alcohol affects an adolescent's brain development in several ways. The consequences of adolescent drinking on particular brain activities are summarized below. Alcohol is a central nervous system depressant. Alcohol can seem to be a stimulant because, before anything else, it suppresses the part of the brain that governs inhibitions.

CORTEX-- Alcohol hampers the cortex as it processes details from an individual's senses.

CENTRAL NERVOUS SYSTEM-- When a person thinks about something he wants his body to do, the central nervous system-- the brain and the spine-- sends a signal to that portion of the body. Alcohol slows down the central nervous system, making the individual think, speak, and move less quickly.

FRONTAL LOBES -- The brain's frontal lobes are very important for organizing, creating ideas, decision making, and employing self-control.

When alcohol impacts the frontal lobes of the brain, a person might find it tough to control his or her feelings and impulses. The person may act without thinking or might even get violent. Drinking alcohol over an extended period of time can harm the frontal lobes forever.

HIPPOCAMPUS-- The hippocampus is the part of the brain in which memories are made. When alcohol reaches the hippocampus, an individual may have difficulty recalling something she or he just learned, like a name or a phone number. This can take place after just a couple of drinks. Drinking a great deal of alcohol quickly can cause a blackout-- not being able to recall entire occurrences, such as what she or he did last night. If alcohol harms the hippocampus, a person may find it tough to learn and to hang on to knowledge.

CEREBELLUM-- The cerebellum is essential for coordination, thoughts, and attention. When alcohol enters the cerebellum, an individual may have trouble with these abilities. After drinking alcohol, a person's hands might 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 an incredible number of the physical body's housekeeping tasks. Alcohol upsets the operation of the hypothalamus. After an individual drinks alcohol, blood pressure, hunger, being thirsty, and the impulse to urinate increase while body temperature level and heart rate decrease.

MEDULLA-- The medulla controls the physical body's unconscious actions, such as a person's heart beat. It also keeps the body at the ideal temperature. Alcohol really chills the physical body. Drinking a great deal of alcohol outdoors in cold weather can trigger an individual's body temperature to drop below normal. This harmful situation is termed hypothermia.

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

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

Alcohol in fact chills the physical body. Consuming a lot of alcohol outdoors in cold weather conditions can trigger a person's body temperature level to fall below normal.
