Alcohol Consumption Can Trigger Alterations In The Structure And Operation Of The Blossoming Brain
Alcohol can trigger alterations in the structure and function of the growing 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 defined by remarkable changes to the brain's architecture, neuron connectivity ("electrical wiring"), and physiology. These changes in the brain affect everything from developing sexuality to emotions and cognitive ability.
Not all portions of the juvenile brain mature at the same time, which may put a juvenile at a disadvantage in certain circumstances. For example, the limbic areas of the brain mature quicker than the frontal lobes. The limbic regions manage emotions and are related to a juvenile's lowered sensitivity to risk. The frontal lobes are responsible for self-regulation, judgment, reasoning, analytic skills, and impulse control. Variations in maturation among parts of the brain can result in rash choices or actions and a neglect for repercussions.
How Alcohol Disturbs the Brain
Alcohol affects an adolescent's brain development in many ways. The repercussions of adolescent drinking on particular brain activities are discussed below.
Alcohol is a central nervous system sedative drug. Alcohol can appear to be a stimulant because, to begin with, it depresses the part of the human brain that regulates inhibitions.

CORTEX-- Alcohol slows down the cortex as it works with information 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 part of the physical body. Alcohol hinders the central nervous system, making the individual think, communicate, and move less quickly.
FRONTAL LOBES -- The human brain's frontal lobes are essential for organizing, forming ideas, decision making, and using self-discipline.
Once alcohol impairs the frontal lobes of the brain, a person might find it difficult to manage his or her feelings and urges. The person might act without thinking or might even get violent. Consuming alcohol over an extended period of time can damage the frontal lobes forever.
HIPPOCAMPUS-- The hippocampus is the part of the human brain where memories are generated.
Once alcohol reaches the hippocampus, a person may have trouble recollecting something she or he just learned, such as a person's name or a phone number. This can happen after just a couple of drinks.
Drinking a great deal of alcohol rapidly can cause a blackout-- not having the ability to recollect whole events, like what he or she did last night.
An individual might find it hard to learn and to hold on to information if alcohol damages the hippocampus.
CEREBELLUM-- The cerebellum is essential for coordination, ideas, and awareness. When alcohol enters the cerebellum, an individual might have trouble with these skills. After consuming alcohol, an individual's hands might be so shaky that they can't touch or grab things properly, and they might fail to keep their balance and fall.
HYPOTHALAMUS-- The hypothalamus is a little part of the brain that does a remarkable variety of the body's housekeeping chores. Alcohol frustrates the operation of the hypothalamus. After an individual drinks alcohol, blood pressure, hunger, being thirsty, and the urge to urinate increase while body temperature level and heart rate decrease.
MEDULLA-- The medulla controls the body's automatic actions, such as a person's heartbeat. It likewise keeps the physical body at the ideal temperature. Alcohol in fact chills the physical body. Drinking a lot of alcohol outdoors in cold weather can cause a person's body temperature level to drop below normal. This hazardous situation is called hypothermia.
A person might have difficulty with these skills once alcohol gets in the cerebellum. After drinking alcohol, a person's hands may be so tremulous that they can't touch or grab things normally, and they may lose their equilibrium and tumble.
After an individual alcoholic beverages alcohol, blood pressure, appetite, thirst, and the urge to urinate increase while body temperature levels and heart rate decline.
Alcohol in fact cools down the body. Consuming a lot of alcohol outdoors in cold weather conditions can trigger an individual's physical body temperature level to drop below normal.
