Drinking Alcohol Can Create Changes In The Blossoming BrainAlcohol consumption can trigger changes in the structure and operation of the growing brain, which continues to mature 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 structure, neuron connectivity ("circuitry"), and physiology. These changes in the brain alter everything from emerging sexuality to emotions and cognitive ability.
Not all parts of the adolescent brain mature at the same time, which might put an adolescent at a disadvantage in particular circumstances. The limbic regions of the brain mature earlier than the frontal lobes.
The way Alcohol Alters the Brain Alcohol alters an adolescent's brain development in many ways. The consequences of adolescent alcohol consumption on particular brain activities are discussed below. Alcohol is a central nervous system sedative drug. Alcohol can appear to be a stimulant because, at the start, it suppresses the portion of the brain that governs inhibitions.
CEREBRAL CORTEX-- Alcohol slows down the cortex as it works with details from an individual's senses.
CENTRAL NERVOUS SYSTEM-- When an individual thinks of something he desires his body to undertake, the central nervous system-- the brain and the spinal cord-- sends 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 necessary for planning, forming concepts, decision making, and exercising self-discipline.
An individual might find it hard to manage his or her feelings and urges once alcohol impairs the frontal lobes of the brain. The individual might act without thinking or may even get violent. Consuming alcohol over an extended period of time can harm the frontal lobes forever.
HIPPOCAMPUS-- The hippocampus is the portion of the brain in which memories are generated. Once alcohol reaches the hippocampus, a person might have difficulty recalling a thing he or she just learned, like a person's name or a telephone number. This can happen after just one or two alcoholic beverages. Drinking a lot of alcohol quickly can trigger a blackout-- not being able to remember whole happenings, like what exactly he or she did last night. An individual may find it tough to learn and to hold on to information if alcohol harms the hippocampus.
CEREBELLUM-- The cerebellum is important for coordination, ideas, and focus. 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 take hold of things properly, and they might fail to keep their balance and tumble.
HYPOTHALAMUS-- The hypothalamus is a little part of the brain that does an incredible variety of the physical body's housekeeping tasks. Alcohol upsets the work of the hypothalamus. After an individual consumes alcohol, blood pressure, hunger, thirst, and the impulse to urinate intensify while physical body temperature and heart rate decrease.
Alcohol in fact chills the body. Drinking a lot of alcohol outdoors in cold weather conditions can trigger a person's physical body temperature level to fall below normal.
A person might have difficulty with these skills when alcohol goes into the cerebellum. After drinking alcohol, an individual's hands may be so tremulous that they cannot touch or get hold of things properly, and they might lose their equilibrium and tumble.
After a person alcoholic beverages alcohol, blood pressure, appetite, being thirsty, and the desire to urinate increase while physical body temperature and heart rate decrease.
