Alcohol consumption can trigger changes in the structure and operation of the blossoming brain, which continues to mature into an individual's mid 20s, and it might have repercussions reaching far beyond teenage years.
In adolescence, brain growth is identified by remarkable modifications to the brain's architecture, neural connections ("circuitry"), and physiology. These transformations in the brain affect everything from developing sexuality to emotionality and cognitive ability.
Not all parts of the adolescent brain mature at the same time, which may put a juvenile at a disadvantage in certain circumstances. The limbic areas of the brain mature sooner than the frontal lobes.
Ways Alcohol Disturbs the Human Brain
Alcohol affects a juvenile's brain development in numerous ways. The consequences of juvenile drinking on particular brain functions are detailed below.
Alcohol is a central nervous system sedative. Alcohol can appear to be a stimulant because, to begin with, it suppresses the portion of the human brain that governs inhibitions.
CORTEX-- Alcohol hampers the cortex as it processes details from a person'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 body. Alcohol reduces the central nervous system, making the individual think, speak, and move slower.
FRONTAL LOBES -- The brain's frontal lobes are very important for organizing, creating concepts, decision making, and exercising self-discipline.
Once alcohol impairs the frontal lobes of the brain, a person might find it tough to control his/her feelings and impulses. The person may act without thinking or might even get violent. Consuming alcohol over a long period of time can harm the frontal lobes forever.
HIPPOCAMPUS-- The hippocampus is the part of the human brain where memories are generated.
Once alcohol reaches the hippocampus, an individual may have difficulty recollecting something he or she just learned, like a name or a telephone number. This can occur after just one or two drinks.
Drinking a great deal of alcohol quickly can trigger a blackout-- not being able to recollect entire occurrences, such as what exactly she or he did last night.
An individual may find it hard to learn and to hold on to knowledge if alcohol harms the hippocampus.
CEREBELLUM-- The cerebellum is essential for coordination, thoughts, and attention. When alcohol enters the cerebellum, a person might have trouble with these skills. After drinking alcohol, a person's hands may be so tremulous that they can't 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 fantastic number of the physical body's housekeeping tasks. Alcohol frustrates the operation of the hypothalamus. After a person consumes alcohol, blood pressure, hunger, being thirsty, and the impulse to urinate intensify while body temperature and heart rate decrease.
MEDULLA-- The medulla controls the body's automatic actions, such as an individual's heartbeat. It also keeps the body at the best temperature. Alcohol really cools down the body. Drinking a great deal of alcohol outdoors in chilly weather can trigger an individual's physical body temperature level to fall below its normal level. This harmful situation is called hypothermia.
An individual might have trouble with these abilities when alcohol gets in the cerebellum. After drinking alcohol, an individual's hands may be so shaky that they can't touch or take hold of things properly, and they may fail to keep their equilibrium and fall.
After a person drinks alcohol, blood pressure, hunger, being thirsty, and the desire to urinate increase while physical body temperature and heart rate decrease.
Alcohol actually chills the physical body. Drinking a lot of alcohol outdoors in cold weather conditions can trigger an individual's physical body temperature level to fall below normal.additional assistance with alcohol abuse . . .
