Alcohol Can Trigger Modifications In The Growing Brainalcohol can trigger modifications in the architecture and function of the growing brain, which continues to develop into a person's mid 20s, and it may have repercussions reaching far beyond adolescence.
In adolescence, brain growth is identified by remarkable changes to the brain's architecture, neural connections ("electrical wiring"), and physiology. These transformations in the brain disturb everything from emerging sexuality to emotionality and cognitive ability.
Not all parts of the juvenile brain mature at the exact same time, which may put a juvenile at a disadvantage in particular circumstances. The limbic regions of the brain develop sooner than the frontal lobes.
The way Alcohol Disturbs the Brain Alcohol alters a juvenile's brain development in many ways. The results of adolescent drinking on specific brain functions are discussed below. Alcohol is a central nervous system sedative. Alcohol can appear to be a stimulant because, initially, it depresses the part of the brain that manages inhibitions.
CEREBRAL CORTEX-- Alcohol reduces the cerebral cortex as it processes information from a person's senses.
CENTRAL NERVOUS SYSTEM-- When a person thinks about something he wants his body to undertake, the central nervous system-- the brain and the spine-- sends out a signal to that portion of the physical body. Alcohol hinders the central nervous system, making the individual think, speak, and move more slowly.
FRONTAL LOBES -- The brain's frontal lobes are essential for planning, creating concepts, making decisions, and exercising self-discipline.
Once alcohol affects the frontal lobes of the brain, an individual might find it difficult to control his/her emotions and urges. The person may act without thinking or may even become violent. drinking alcohol over a long period of time can damage the frontal lobes permanently.
HIPPOCAMPUS-- The hippocampus is the part of the brain in which memories are generated. Once alcohol reaches the hippocampus, an individual might have trouble recalling something she or he just learned, such as a name or a telephone number. This can occur after just one or two drinks. Drinking a lot of alcohol quickly can cause a blackout-- not having the ability to recall whole incidents, such as what exactly she or he did last night. A person might find it difficult to learn and to hold on to information if alcohol harms the hippocampus.
CEREBELLUM-- The cerebellum is very important for coordination, ideas, and attention. An individual may have trouble with these skills when alcohol enters the cerebellum. After consuming alcohol, a person's hands might be so unsteady that they cannot touch or take hold of things normally, and they may lose their equilibrium and fall.
HYPOTHALAMUS-- The hypothalamus is a little part of the brain that does an amazing number of the body's housekeeping tasks. Alcohol frustrates the operation of the hypothalamus. After a person consumes alcohol, blood pressure, appetite, being thirsty, and the impulse to urinate intensify while physical body temperature and heart rate decline.
Alcohol in fact chills the body. Consuming a lot of alcohol outdoors in cold weather conditions can cause a person's body temperature to drop below normal.
A person might have difficulty with these abilities once alcohol enters the cerebellum. After consuming alcohol, an individual's hands may be so unsteady that they can't touch or get hold of things normally, and they might fail to keep their equilibrium and tumble.
After a person drinks alcohol, blood pressure, appetite, being thirsty, and the desire to urinate increase while physical body temperature levels and heart rate decrease.
Alcohol actually chills the body. Drinking a lot of alcohol outdoors in cold weather conditions can trigger a person's body temperature level to fall below normal.
