Alcohol consumption can cause modifications in the structure and function of the blossoming brain, which continues to develop into an individual's mid 20s, and it may have consequences reaching far beyond adolescence.
In adolescence, brain growth is defined by remarkable changes to the brain's structure, neural connections ("circuitry"), and physiology. These transformations in the brain alter everything from emerging sexuality to emotions and cognitive ability.
Not all parts of the juvenile brain mature at the same time, which might put an adolescent at a disadvantage in certain scenarios. The limbic areas of the brain mature earlier than the frontal lobes.
The way Alcohol Affects the Human Brain Alcohol affects an adolescent's brain growth in many ways. The effects of adolescent alcohol consumption on particular brain activities are summarized below. Alcohol is a central nervous system depressant. Alcohol can appear to be a stimulant because, initially, it suppresses the part of the human brain that regulates inhibitions.
CEREBRAL CORTEX-- Alcohol hampers the cortex as it works with 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 a signal to that portion of the body. Alcohol slows down the central nervous system, making the individual think, converse, and move less quickly.
FRONTAL LOBES -- The brain's frontal lobes are essential for organizing, creating concepts, decision making, and using self-control.
Once alcohol affects the frontal lobes of the brain, an individual might find it tough to control his/her emotions and urges. The person might act without thinking or might even get violent. drinking alcohol over a long period of time can injure the frontal lobes forever.
HIPPOCAMPUS-- The hippocampus is the part of the brain in which memories are made. Once alcohol gets to the hippocampus, a person may have difficulty recollecting a thing she or he just learned, such as a person's name or a telephone number. This can occur after just a couple of alcoholic beverages. Drinking a lot of alcohol quickly can cause a blackout-- not having the ability to recall whole happenings, such as what she or he did the night before. An individual may find it difficult to learn and to hold on to information if alcohol harms the hippocampus.
CEREBELLUM-- The cerebellum is very important for coordination, thoughts, and awareness. An individual may have difficulty with these abilities once alcohol gets in the cerebellum. After drinking alcohol, a person's hands might be so shaky that they cannot touch or get hold of things properly, and they may lose their balance and fall.
HYPOTHALAMUS-- The hypothalamus is a small part of the brain that does an amazing variety of the body's housekeeping tasks. Alcohol frustrates the work of the hypothalamus. After an individual drinks alcohol, blood pressure, appetite, thirst, and the need to urinate intensify while physical body temperature level and heart rate decrease.
MEDULLA-- The medulla manages the body's unconscious actions, such as an individual's heart beat. It also keeps the body at the best temperature level. alcohol in fact cools down the physical body. Consuming a lot of alcohol outdoors in cold weather can trigger a person's body temperature level to fall below normal. This unsafe situation is called hypothermia.
An individual may have difficulty with these skills once alcohol gets in the cerebellum. After consuming alcohol, an individual's hands may be so unsteady that they cannot touch or get hold of things properly, and they may lose their balance and tumble.
After a person drinks alcohol, blood pressure, appetite, being thirsty, and the urge to urinate increase while body temperature levels and heart rate decrease.
Alcohol in fact chills the physical body. Drinking a lot of alcohol outdoors in cold weather can cause an individual's body temperature to drop below normal.
