Alcohol Use Can Trigger Alterations In The Blossoming BrainAlcohol can trigger modifications in the structure and function of the developing brain, which continues to grow into an individual's mid 20s, and it may have consequences reaching far beyond adolescence.
In adolescence, brain development is defined by dramatic modifications to the brain's architecture, neural connections ("electrical wiring"), and physiology. These changes in the brain alter everything from emerging sexuality to emotions and judgment.
Not all component parts of the adolescent brain mature simultaneously, which might put a juvenile at a disadvantage in specific circumstances. For example, the limbic regions of the brain develop quicker than the frontal lobes. The limbic regions control feelings and are associated with an adolescent's reduced sensitivity to risk. The frontal lobes are responsible for self-control, judgment, reasoning, problem-solving, and impulse control. Variations in maturation among parts of the brain can result in careless decisions or actions and a disregard for repercussions.
The way Alcohol Alters the Human Brain Alcohol alters a juvenile's brain growth in several ways. The consequences of minor drinking on specific brain functions are discussed below. Alcohol is a central nervous system sedative drug. Alcohol can seem to be a stimulant because, at the start, it suppresses the part of the human brain that manages inhibitions.
CORTEX-- Alcohol hinders the cortex as it works with information from an individual's senses.
CENTRAL NERVOUS SYSTEM-- When a person thinks of something he wants his body to do, the central nervous system-- the brain and the spine-- sends out a signal to that portion of the body. Alcohol reduces the central nervous system, making the person think, converse, and move slower.
FRONTAL LOBES -- The human brain's frontal lobes are essential for planning, creating concepts, making decisions, and exercising self-discipline.
Once alcohol impacts the frontal lobes of the human brain, a person might find it difficult to manage his/her feelings and urges. The individual may act without thinking or may even become violent. Consuming alcohol over a long period of time can harm the frontal lobes forever.
HIPPOCAMPUS-- The hippocampus is the portion of the brain in which memories are created. When alcohol gets to the hippocampus, an individual might have difficulty remembering a thing she or he just learned, such as a person's name or a phone number. This can occur after just one or two alcoholic beverages. Drinking a great deal of alcohol rapidly can trigger a blackout-- not being able to recall whole occurrences, like what exactly he or she did the night before. A person might find it difficult to learn and to hold on to information if alcohol damages the hippocampus.
CEREBELLUM-- The cerebellum is very important for coordination, ideas, and focus. A person might have difficulty with these skills once alcohol enters the cerebellum. After consuming alcohol, a person's hands may be so shaky that they can't touch or get hold of things properly, and they may lose their balance and fall.
HYPOTHALAMUS-- The hypothalamus is a little part of the brain that does an incredible number of the physical body's housekeeping tasks. Alcohol upsets the work 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 unconscious actions, like an individual's heartbeat. It also keeps the body at the best temperature. Alcohol in fact cools down the physical body. Consuming a lot of alcohol outdoors in cold climates can cause a person's physical body temperature to drop below normal. This harmful condition is knowned as hypothermia.
An individual may have difficulty with these skills when alcohol goes into the cerebellum. After drinking alcohol, an individual's hands might be so tremulous that they can't touch or take hold of things properly, and they may lose their balance and tumble.
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 cools down the body. Drinking a lot of alcohol outdoors in cold weather can cause an individual's physical body temperature level to drop below normal.
