Alcohol can trigger changes in the structure and operation of the growing brain, which continues to grow into an individual's mid 20s, and it might have repercussions reaching far beyond teenage years.
In adolescence, brain development is characterized by dramatic modifications to the brain's architecture, neuron connectivity ("electrical wiring"), and physiology. These changes in the brain disturb everything from emerging sexuality to emotionality and judgment.
Not all parts of the juvenile brain mature at the exact same time, which might put an adolescent at a disadvantage in particular situations. The limbic areas of the brain mature earlier than the frontal lobes.
How Alcohol Alters the Human Brain
Alcohol disturbs an adolescent's brain growth in many ways. alcohol addiction of underage alcohol consumption on particular brain functions are discussed below.
Alcohol is a central nervous system sedative. Alcohol can seem to be a stimulant because, to begin with, it suppresses the portion of the human brain that manages inhibitions.
CORTEX-- Alcohol hampers the cortex as it processes information from a person's senses.
CENTRAL NERVOUS alcohol dependence -- When a person thinks about something he wants his body to undertake, the central nervous system-- the brain and the spinal cord-- sends a signal to that portion of the body. Alcohol reduces the central nervous system, making the person think, converse, and move less quickly.
FRONTAL LOBES -- The human brain's frontal lobes are essential for advanced planning, forming concepts, decision making, and exercising self-control.
When alcohol impacts the frontal lobes of the human brain, an individual might find it hard to manage his or her emotions and impulses. alcohol addiction may act without thinking or may even become 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 made.
When alcohol gets to the hippocampus, a person might have difficulty recollecting something she or he just learned, such as a person's name or a phone number. This can occur after just a couple of alcoholic beverages.
Drinking a lot of alcohol rapidly can trigger a blackout-- not being able to recollect entire events, like what he or she did the night before.
If alcohol harms the hippocampus, a person might find it difficult to learn and to hang on to knowledge.
CEREBELLUM-- The cerebellum is very important for coordination, ideas, and attention. When alcohol goes into the cerebellum, a person may have trouble with these skills. After consuming alcohol, a person's hands may be so tremulous that they can't touch or grab things properly, and they may fail to keep their balance and tumble.
HYPOTHALAMUS-- The hypothalamus is a little part of the brain that does an amazing number of the physical body's housekeeping tasks. Alcohol frustrates the operation of the hypothalamus. After an individual drinks alcohol, blood pressure, appetite, being thirsty, and the need to urinate increase while physical body temperature level and heart rate decrease.
Alcohol in fact chills the body. Consuming a lot of alcohol outdoors in cold weather conditions can trigger an individual's physical body temperature to drop below normal.

After an individual alcoholic beverages alcohol, blood pressure, hunger, being thirsty, and the urge to urinate increase while physical body temperature levels and heart rate decrease.
Alcohol actually cools down the body. Consuming a lot of alcohol outdoors in cold weather conditions can cause an individual's body temperature to fall below normal.
