Alcohol consumption 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 consequences reaching far beyond teenage years.
In adolescence, brain growth is defined by dramatic modifications to the brain's architecture, neural connections ("electrical wiring"), and physiology. These changes in the brain affect everything from emerging sexuality to emotionality and cognitive ability.
Not all parts of the juvenile brain mature concurrently, which might put a youth at a disadvantage in specific circumstances. For instance, the limbic areas of the brain mature quicker than the frontal lobes. The limbic areas manage feelings and are connected with a juvenile's reduced level of sensitivity to risk. The frontal lobes are responsible for self-control, judgment, reasoning, problem-solving, and impulse control. Differences in maturation among parts of the brain can lead to rash choices or actions and a neglect for repercussions.
The way Alcohol Affects the Brain
Alcohol alters an adolescent's brain growth in several ways. The results of juvenile alcohol consumption on specific brain functions are discussed below.
hangover is a central nervous system sedative. alcohol dependence can appear to be a stimulant because, at the start, it suppresses the portion of the human brain that governs inhibitions.
CORTEX-- Alcohol reduces the cerebral cortex as it processes information from a person's senses.
CENTRAL NERVOUS hangovers -- When an individual thinks of something he wants his body to undertake, the central nervous system-- the brain and the spinal cord-- sends a signal to that portion of the body. alcoholism reduces the central nervous system, making the person think, communicate, and move less quickly.
FRONTAL LOBES -- The human brain's frontal lobes are essential for planning, forming concepts, making decisions, and exercising self-discipline.
Once alcoholism of the human brain, a person might find it tough to control his or her emotions and impulses. The person may act without thinking or may even become violent. Drinking alcohol over an extended period of time can damage the frontal lobes permanently.
HIPPOCAMPUS-- The hippocampus is the part of the human brain where memories are made.
When alcohol reaches the hippocampus, an individual may have difficulty recollecting something she or he just learned, like a person's name or a telephone number. This can occur after just one or two alcoholic beverages.
Drinking a lot of alcohol rapidly can cause a blackout-- not having the ability to recall whole incidents, such as what exactly she or he did last night.
An individual may find it difficult to learn and to hold on to knowledge if alcohol harms the hippocampus.
CEREBELLUM-- The cerebellum is important for coordination, thoughts, and awareness. An individual may have difficulty with these skills when alcohol gets in the cerebellum. After drinking alcohol, a person's hands may be so unsteady that they can't touch or take hold of things properly, and they may fail to keep their equilibrium and tumble.
HYPOTHALAMUS-- The hypothalamus is a little part of the brain that does an incredible variety of the physical body's housekeeping chores. Alcohol upsets the operation of the hypothalamus. After a person consumes alcohol, blood pressure, appetite, being thirsty, and the impulse to urinate increase while physical 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 a person's body temperature level to fall below normal.
An individual may have difficulty with these abilities when alcohol enters the cerebellum. After consuming alcohol, an individual's hands may be so shaky that they can't touch or get hold of things properly, and they may lose their balance and fall.
After an individual alcoholic beverages alcohol, blood pressure, hunger, being thirsty, and the desire to urinate increase while body temperature levels and heart rate decrease.
Alcohol actually cools down the body. Consuming a lot of alcohol outdoors in cold weather conditions can trigger a person's body temperature to fall below normal.
