Alcohol can cause modifications in the architecture and function of the growing brain, which continues to develop into a person's mid 20s, and it might have repercussions reaching far beyond adolescence.
In adolescence, brain development is defined 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 cognitive ability.
Not all component parts of the adolescent brain mature simultaneously, which may put a juvenile at a disadvantage in specific circumstances. For example, the limbic areas of the brain mature earlier than the frontal lobes. The limbic areas control emotions and are connected with a juvenile's reduced level of sensitivity to risk. The frontal lobes are responsible for self-regulation, judgment, reasoning, analytic skills, and impulse control. Variations in maturation amongst parts of the brain can result in rash decisions or actions and a neglect for repercussions.
The way Alcohol Alters the Brain Alcohol alters an adolescent's brain development in numerous ways. The results of juvenile drinking on specialized brain functions are discussed below. alcohol is a central nervous system depressant. Alcohol can seem to be a stimulant because, at the start, it depresses the portion of the brain that governs inhibitions.
CORTEX-- Alcohol hinders the cerebral cortex as it works with information from an individual's senses.
CENTRAL NERVOUS SYSTEM-- When an individual thinks of something he desires his body to undertake, the central nervous system-- the brain and the spine-- sends out a signal to that part of the body. Alcohol slows down the central nervous system, making the individual think, communicate, and move more slowly.
FRONTAL LOBES -- The human brain's frontal lobes are essential for advanced planning, creating concepts, making decisions, and employing self-discipline.
A person might find it hard to manage his or her feelings and urges when alcohol impacts the frontal lobes of the brain. The individual might act without thinking or might even get violent. Consuming alcohol over a long period of time can harm the frontal lobes permanently.
HIPPOCAMPUS-- The hippocampus is the portion of the brain in which memories are created. When alcohol reaches the hippocampus, an individual might have trouble recalling something he or she just learned, such as a name or a phone number. This can happen after just one or two alcoholic beverages. Drinking a great deal of alcohol rapidly can trigger a blackout-- not being able to remember entire happenings, such as what exactly she or he did last night. If alcohol harms the hippocampus, an individual may find it hard to learn and to hold on to knowledge.
CEREBELLUM-- The cerebellum is very important for coordination, ideas, and awareness. When alcohol goes into the cerebellum, an individual may have trouble with these abilities. After consuming alcohol, an individual's hands might be so tremulous that they can't touch or get hold of things normally, and they may lose their balance and fall.
HYPOTHALAMUS-- The hypothalamus is a little part of the brain that does a fantastic number of the body's housekeeping tasks. Alcohol frustrates the operation of the hypothalamus. After a person drinks alcohol, blood pressure, hunger, thirst, and the impulse to urinate intensify while body temperature level and heart rate decline.
Alcohol actually cools down the body. Drinking a lot of alcohol outdoors in cold weather conditions can cause an individual's physical body temperature to fall below normal.
A person may have difficulty with these abilities when alcohol goes into the cerebellum. After drinking alcohol, an individual's hands might be so shaky that they cannot 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 decline.
Alcohol in fact cools down the body. Drinking a lot of alcohol outdoors in cold weather conditions can trigger an individual's body temperature to fall below normal.
