Alcohol Can Trigger Alterations In The Structure And Operation Of The Growing Brain
Alcohol can trigger changes in the structure and function of the developing brain, which continues to mature into a person's mid 20s, and it may have consequences reaching far beyond adolescence.
In adolescence, brain growth is characterized by dramatic changes to the brain's structure, neuron connectivity ("electrical wiring"), and physiology. These changes in the brain alter everything from developing sexuality to emotionality and judgment.
Not all parts of the juvenile brain mature at the same time, which might put a juvenile at a disadvantage in particular circumstances. The limbic regions of the brain develop earlier than the frontal lobes.
How alcoholism alters an adolescent's brain development in many ways. The consequences of adolescent alcohol consumption on particular brain functions are discussed below.
alcoholism is a central nervous system sedative. Alcohol can appear to be a stimulant because, initially, it suppresses the portion of the brain that governs inhibitions.
CEREBRAL CORTEX-- Alcohol impedes the cerebral cortex as it processes information from a person's senses.
CENTRAL NERVOUS SYSTEM-- When an individual thinks about something he wants his body to undertake, the central nervous system-- the brain and the spinal cord-- sends out a signal to that part of the body. Alcohol reduces the central nervous system, making the person think, communicate, and move more slowly.
FRONTAL LOBES -- The brain's frontal lobes are essential for organizing, forming ideas, making decisions, and employing self-control.
When alcohol affects the frontal lobes of the human brain, a person might find it hard to manage his or her feelings and impulses. The individual 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 created.
Once alcohol reaches the hippocampus, an individual might have trouble recalling a thing he or she just learned, like a name or a phone number. This can occur after just one or two drinks.
Drinking a great deal of alcohol rapidly can trigger a blackout-- not being able to remember entire incidents, such as what he or she did the night before.
A person may find it tough to learn and to hold on to knowledge if alcohol injures the hippocampus.

CEREBELLUM-- The cerebellum is important for coordination, thoughts, and focus. An individual may have trouble with these skills once alcohol gets in the cerebellum. After drinking alcohol, an individual's hands might be so unsteady that they cannot touch or grab things normally, and they may fail to keep their equilibrium and tumble.
HYPOTHALAMUS-- The hypothalamus is a small part of the brain that does an amazing variety of the physical body's housekeeping tasks. Alcohol frustrates the work of the hypothalamus. After an individual consumes alcohol, blood pressure, hunger, thirst, and the urge to urinate increase while physical body temperature level and heart rate decline.
MEDULLA-- The medulla controls the physical body's automatic actions, like a person's heartbeat. It also keeps the physical body at the ideal temperature level. Alcohol in fact chills the physical body. Drinking alcoholism of alcohol outdoors in cold weather can cause an individual's body temperature level to drop below normal. alcoholic is knowned as hypothermia.
alcoholic may have trouble with these abilities once alcohol enters the cerebellum. After drinking alcohol, an individual's hands might be so shaky that they cannot touch or take hold of things normally, and they may lose their balance and fall.
After an individual drinks alcohol, blood pressure, hunger, being thirsty, and the desire to urinate increase while body temperature and heart rate decrease.
Alcohol actually chills the physical body. Consuming a lot of alcohol outdoors in cold weather conditions can cause a person's body temperature level to drop below normal.
