Alcohol Consumption Can Cause Alterations In the Growing Brainalcohol can trigger modifications in the architecture and operation of the developing brain, which continues to grow into a person's mid 20s, and it may have repercussions reaching far beyond adolescence.
In adolescence, brain development is identified by dramatic changes to the brain's architecture, neuron connectivity ("electrical wiring"), 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 exact same time, which may put a juvenile at a disadvantage in specific situations. The limbic areas of the brain mature sooner than the frontal lobes.
Ways Alcohol Alters the Brain Alcohol affects an adolescent's brain growth in numerous ways. The results of adolescent alcohol consumption on specific brain activities are detailed below. Alcohol is a central nervous system sedative. Alcohol can appear to be a stimulant because, before anything else, it depresses the part of the human brain that manages inhibitions.
CORTEX-- Alcohol hinders the cerebral cortex as it works with information 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 spine-- sends out a signal to that part of the physical body. Alcohol hampers the central nervous system, making the individual think, communicate, and move more slowly.
FRONTAL LOBES -- The brain's frontal lobes are very important for organizing, creating concepts, making decisions, and using self-discipline.
Once alcohol affects the frontal lobes of the brain, a person might find it hard to control his or her emotions and urges. The person might act without thinking or may even become violent. Consuming alcohol over an extended period of time can injure the frontal lobes forever.
HIPPOCAMPUS-- The hippocampus is the portion of the human brain in which memories are made. Once alcohol reaches the hippocampus, an individual may have trouble recalling a thing she or he just learned, such as a person's name or a phone number. This can happen after just one or two drinks. drinking a great deal of alcohol quickly can cause a blackout-- not being able to recall whole happenings, like what she or he did last night. An individual may find it difficult to learn and to hold on to information if alcohol harms the hippocampus.
CEREBELLUM-- The cerebellum is essential for coordination, ideas, and attention. When alcohol goes into the cerebellum, a person might have trouble with these skills. After consuming alcohol, an individual's hands may be so tremulous that they can't touch or get hold of things properly, and they might lose their balance and tumble.
HYPOTHALAMUS-- The hypothalamus is a little part of the brain that does an incredible number of the physical body's housekeeping tasks. Alcohol frustrates the work of the hypothalamus. After a person drinks alcohol, blood pressure, appetite, being thirsty, and the urge to urinate intensify while physical body temperature and heart rate decrease.
MEDULLA-- The medulla manages the body's unconscious actions, like a person's heart beat. It also keeps the body at the ideal temperature level. Alcohol really cools down the body. Drinking a great deal of alcohol outdoors in cold weather can trigger an individual's physical body temperature level to drop below normal. This harmful situation is termed hypothermia.
An individual may have trouble with these skills once alcohol gets in the cerebellum. After drinking alcohol, a person's hands might be so shaky that they can't touch or take hold of things properly, and they might fail to keep their equilibrium and tumble.
After an individual drinks alcohol, blood pressure, hunger, thirst, and the urge to urinate increase while body temperature levels and heart rate decrease.
Alcohol actually cools down the body. Drinking a lot of alcohol outdoors in cold weather can cause a person's body temperature level to fall below normal.
