Alcohol Can Trigger Alterations In The Architecture And Function Of The Growing Brain

Alcohol can trigger modifications in the architecture and function of the blossoming brain, which continues to grow into an individual's mid 20s, and it might have repercussions reaching far beyond adolescence.
In adolescence, brain growth is identified by remarkable changes to the brain's structure, neuron connectivity ("circuitry"), and physiology. These changes in the brain alter everything from developing sexuality to emotions and judgment.
Not all parts of the adolescent brain mature at the same time, which might put a juvenile at a disadvantage in specific situations. The limbic areas of the brain mature sooner than the frontal lobes.
How Alcohol Disturbs the Brain
Alcohol alters a juvenile's brain development in several ways. The consequences of minor drinking on specialized brain activities are discussed below.
Alcohol is a central nervous system depressant. Alcohol can appear to be a stimulant because, to begin with, it depresses the part of the brain that regulates inhibitions.
CEREBRAL CORTEX-- Alcohol hinders the cortex as it processes 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 spinal cord-- sends a signal to that portion of the physical body. Alcohol hinders the central nervous system, making the individual think, speak, and move slower.
FRONTAL LOBES -- The brain's frontal lobes are important for advanced planning, creating ideas, making decisions, and exercising self-discipline.
A person might find it tough to manage his or her emotions and urges when alcohol impacts the frontal lobes of the brain. The person might act without thinking or might even become violent. Drinking 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.
Once alcohol reaches the hippocampus, an individual may have difficulty recalling something she or he just learned, such as a person's name or a telephone number. This can happen after just one or two drinks.
Drinking a great deal of alcohol rapidly can cause a blackout-- not having the ability to recall entire occurrences, such as what exactly she or he did last night.
An individual might find it hard to learn and to hold on to knowledge if alcohol damages the hippocampus.
CEREBELLUM-- The cerebellum is very important for coordination, ideas, and awareness. When alcohol gets in the cerebellum, an individual may have difficulty with these skills. After consuming alcohol, a person's hands may be so unsteady that they cannot touch or take hold of things properly, and they may lose their equilibrium and tumble.
HYPOTHALAMUS-- The hypothalamus is a small part of the brain that does a remarkable number of the physical body's housekeeping tasks. Alcohol frustrates the work of the hypothalamus. After a person drinks alcohol, blood pressure, hunger, being thirsty, and the urge to urinate intensify while body temperature and heart rate decline.
MEDULLA-- The medulla manages the physical body's automatic actions, such as an individual's heartbeat. It also keeps the physical body at the ideal temperature level. Alcohol actually cools down the body. Drinking a great deal of alcohol outdoors in cold weather can trigger an individual's physical body temperature level to fall below normal. This hazardous situation is termed hypothermia.
A person may have difficulty with these skills when alcohol goes into the cerebellum. After drinking alcohol, a person's hands might be so shaky that they cannot touch or grab things properly, and they might lose their balance and fall.
After an individual alcoholic beverages alcohol, blood pressure, appetite, being thirsty, and the desire to urinate increase while body temperature and heart rate decline.
Alcohol actually chills the physical body. Drinking a lot of alcohol outdoors in cold weather can cause an individual's physical body temperature to fall below normal.
