alcohol can trigger modifications in the architecture and function of the growing brain, which continues to mature into a person's mid 20s, and it might have consequences reaching far beyond adolescence.
In adolescence, brain development is characterized by dramatic modifications to the brain's structure, neural connections ("circuitry"), and physiology. These transformations in the brain disturb everything from developing sexuality to emotionality and judgment.
Not all component parts of the juvenile brain mature concurrently, which may put a youth at a disadvantage in specific circumstances. For example, the limbic regions of the brain mature earlier than the frontal lobes. The limbic regions 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. Variations in maturation among parts of the brain can lead to careless choices or actions and a disregard for consequences.
How Alcohol Alters the Brain Alcohol affects an adolescent's brain growth in numerous ways. The consequences of minor drinking on specialized brain functions are explained below. Alcohol is a central nervous system sedative drug. Alcohol can appear to be a stimulant because, before anything else, it depresses the part of the human brain that regulates inhibitions.
CEREBRAL CORTEX-- Alcohol impedes the cortex as it processes details from a person'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 reduces the central nervous system, making the person think, speak, and move less quickly.
FRONTAL LOBES -- The brain's frontal lobes are essential for advanced planning, forming concepts, making decisions, and employing self-control.
When alcohol impacts the frontal lobes of the brain, a person may find it difficult to manage his/her feelings and impulses. The person might act without thinking or may even become violent. Consuming alcohol over an extended period of time can harm the frontal lobes permanently.
HIPPOCAMPUS-- The hippocampus is the part of the human brain where memories are created. Once alcohol reaches the hippocampus, a person may have trouble remembering a thing he or she just learned, like a name or a phone number. This can take place after just one or two alcoholic beverages. drinking a lot of alcohol quickly can trigger a blackout-- not having the ability to recall whole occurrences, like what she or he did the night before. A person may find it hard to learn and to hold on to knowledge if alcohol harms the hippocampus.
CEREBELLUM-- The cerebellum is essential for coordination, to form thoughts, and attention. When alcohol gets in the cerebellum, a person might have difficulty with these skills. After consuming alcohol, a person's hands might be so tremulous that they can't touch or get hold of things properly, and they might lose their equilibrium and tumble.
HYPOTHALAMUS-- The hypothalamus is a small part of the brain that does a fantastic number of the body's housekeeping tasks. Alcohol upsets the work of the hypothalamus. After a person consumes alcohol, blood pressure, appetite, being thirsty, and the need 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 trigger a person's physical body temperature to drop below normal.
A person might have difficulty with these skills when alcohol goes into the cerebellum. After drinking alcohol, a person's hands might be so unsteady that they cannot touch or take hold of things normally, and they may fail to keep their equilibrium and fall.
After a person alcoholic beverages alcohol, blood pressure, hunger, being thirsty, and the urge to urinate increase while body temperature and heart rate decline.
Alcohol actually chills the physical body. Drinking a lot of alcohol outdoors in cold weather can trigger an individual's physical body temperature level to fall below normal.
