Alcohol consumption can cause modifications in the architecture and operation of the developing brain, which continues to develop into an individual's mid 20s, and it may have repercussions reaching far beyond adolescence.
In adolescence, brain growth is defined by dramatic modifications to the brain's architecture, neuron connectivity ("circuitry"), and physiology. These transformations in the brain alter everything from emerging sexuality to emotionality and cognitive ability.
Not all parts of the juvenile brain mature at the exact same time, which might put a juvenile at a disadvantage in specific circumstances. The limbic regions of the brain mature earlier than the frontal lobes.
How Alcohol Affects the Human Brain Alcohol disturbs a juvenile's brain development in several ways. The consequences 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, at the start, it suppresses the part of the brain that regulates inhibitions.
CORTEX-- Alcohol impedes the cerebral cortex as it processes details from an individual's senses.
CENTRAL NERVOUS SYSTEM-- When a person thinks of something he wants his body to do, the central nervous system-- the brain and the spinal cord-- sends out a signal to that part of the body. Alcohol reduces the central nervous system, making the individual think, communicate, and move less quickly.
FRONTAL LOBES -- The brain's frontal lobes are very important for planning, forming ideas, making decisions, and employing self-control.
A person may find it difficult to manage his or her emotions and urges when alcohol impacts the frontal lobes of the brain. The individual may act without thinking or may even become violent. drinking alcohol over an extended period of time can damage the frontal lobes forever.
HIPPOCAMPUS-- The hippocampus is the portion of the human brain in which memories are created. When alcohol gets to the hippocampus, a person might have difficulty recollecting something he or she just learned, such as a person's name or a telephone number. This can take place after just a couple of alcoholic beverages. Drinking a great deal of alcohol quickly can cause a blackout-- not having the ability to recollect whole events, like what he or she did last night. If alcohol injures the hippocampus, an individual may find it difficult to learn and to hold on to knowledge.
CEREBELLUM-- The cerebellum is necessary for coordination, ideas, and focus. When alcohol enters the cerebellum, a person might have difficulty with these abilities. After consuming alcohol, an individual's hands might be so shaky that they can't touch or get hold of things properly, and they might lose their balance and tumble.
HYPOTHALAMUS-- The hypothalamus is a small part of the brain that does a remarkable variety of the physical body's housekeeping tasks. Alcohol upsets the operation of the hypothalamus. After an individual consumes alcohol, blood pressure, appetite, being thirsty, and the need to urinate intensify while physical body temperature and heart rate decrease.
Alcohol in fact chills the physical body. Consuming a lot of alcohol outdoors in cold weather conditions can trigger an individual's body temperature to drop below normal.
An individual might have difficulty with these skills when alcohol enters the cerebellum. After consuming alcohol, an individual's hands may be so tremulous that they can't touch or take hold of things properly, and they may lose their balance and fall.
After an individual alcoholic beverages alcohol, blood pressure, appetite, being thirsty, and the urge to urinate increase while body temperature levels and heart rate decrease.
Alcohol in fact cools down the physical body. Consuming a lot of alcohol outdoors in cold weather can cause a person's physical body temperature to drop below normal.
