Alcohol Consumption Can Trigger Changes In The Structure And Operation Of The Blossoming Brain

Alcohol can cause alterations in the structure and operation of the developing brain, which continues to mature into an individual's mid 20s, and it might have repercussions reaching far beyond adolescence.
In adolescence, brain growth is defined by remarkable modifications to the brain's architecture, neural connections ("electrical wiring"), and physiology. These transformations in the brain disturb everything from emerging sexuality to emotions and cognitive ability.
Not all portions of the adolescent brain mature concurrently, which might put an adolescent at a disadvantage in certain situations. For example, the limbic areas of the brain mature quicker than the frontal lobes. The limbic areas control emotions and are related to a juvenile's reduced sensitivity to risk. The frontal lobes are responsible for self-control, judgment, reasoning, analytic skills, and impulse control. Differences in maturation among parts of the brain can lead to impulsive decisions or acts and a neglect for consequences.
Ways Alcohol Affects the Human Brain
Alcohol disturbs an adolescent's brain growth in many ways. The consequences of minor alcohol consumption on specific brain functions are summarized below.
Alcohol is a central nervous system depressant. Alcohol can appear to be a stimulant because, before anything else, it depresses the portion of the human brain that governs inhibitions.
CORTEX-- Alcohol slows down the cortex as it works with details from a person's senses.
CENTRAL NERVOUS SYSTEM-- When an individual thinks about something he desires his body to do, the central nervous system-- the brain and the spinal cord-- sends a signal to that part of the physical body. Alcohol hampers the central nervous system, making the individual think, speak, and move slower.
FRONTAL LOBES -- The brain's frontal lobes are very important for planning, forming concepts, making decisions, and employing self-discipline.
An individual may find it difficult to control his or her feelings and urges when alcohol affects the frontal lobes of the brain. The person may 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 part of the brain in which memories are made.
Once alcohol reaches the hippocampus, an individual might have difficulty recollecting something he or she just learned, like a name or a phone number. This can happen after just a couple of alcoholic beverages.
Drinking a great deal of alcohol rapidly can cause a blackout-- not being able to remember entire events, like what he or she did the night before.
If alcohol damages the hippocampus, an individual may find it hard to learn and to hang on to knowledge.
CEREBELLUM-- The cerebellum is very important for coordination, thoughts, and awareness. Once alcohol enters the cerebellum, a person may have difficulty with these abilities. After consuming alcohol, an individual's hands might be so tremulous that they cannot touch or take hold of things properly, and they might lose their balance and fall.
HYPOTHALAMUS-- The hypothalamus is a small part of the brain that does an amazing number of the physical body's housekeeping tasks. Alcohol frustrates the work of the hypothalamus. After an individual consumes alcohol, blood pressure, appetite, being thirsty, and the impulse to urinate increase while physical body temperature level and heart rate decrease.
MEDULLA-- The medulla controls the body's unconscious actions, like an individual's heart beat. It also keeps the physical body at the best temperature level. Alcohol in fact chills the body. Consuming a great deal of alcohol outdoors in cold weather can cause an individual's body temperature level to drop below its normal level. This dangerous condition is called hypothermia.
A person may have difficulty with these skills when alcohol enters the cerebellum. After drinking alcohol, an individual's hands might be so unsteady that they can't touch or grab things properly, and they might lose their balance and fall.
After a person drinks alcohol, blood pressure, hunger, thirst, and the urge to urinate increase while body temperature 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 physical body temperature to fall below normal.
