Alcohol Can Cause Changes In The Structure And Operation Of The Developing Brain
|
|
Alcohol can trigger modifications in the structure and function of the growing brain, which continues to grow into a person's mid 20s, and it may have consequences reaching far beyond adolescence.
In adolescence, brain development is characterized by dramatic modifications to the brain's architecture, neural connections ("circuitry"), and physiology. These transformations in the brain affect everything from emerging sexuality to emotions and judgment.
Not all component parts of the juvenile brain mature concurrently, which might put an adolescent at a disadvantage in particular scenarios. For example, the limbic areas of the brain develop earlier than the frontal lobes. The limbic areas regulate emotions and are related to an adolescent's lowered level of sensitivity to risk. alcoholism are accountable for self-control, judgment, reasoning, analytic skills, and impulse control. Differences in maturation among parts of the brain can result in rash decisions or actions and a disregard for repercussions.
How Alcohol Alters the Brain
Alcohol alters an adolescent's brain growth in many ways. The effects of adolescent alcohol consumption on specific brain activities are explained below.
alcoholism is a central nervous system depressant. Alcohol can seem to be a stimulant because, to begin with, it suppresses the part of the brain that controls inhibitions.
CEREBRAL CORTEX-- Alcohol reduces the cerebral cortex as it processes information from a person'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 spine-- sends a signal to that portion of the physical body. Alcohol hampers the central nervous system, making the individual think, speak, and move slower.
FRONTAL LOBES -- The human brain's frontal lobes are important for planning, forming concepts, making decisions, and using self-control.
Once alcohol affects the frontal lobes of the human brain, a person may find it hard to control his or her emotions and urges. The individual may act without thinking or might even become violent. Consuming alcohol over an extended period of time can harm the frontal lobes forever.
HIPPOCAMPUS-- The hippocampus is the portion of the brain in which memories are generated.
When alcohol reaches the hippocampus, a person might have trouble remembering something she or he just learned, such as a person's name or a telephone number. This can take place after just one or two alcoholicalcoholic beverages.
Drinking a lot of alcohol rapidly can cause a blackout-- not being able to recollect entire happenings, like what she or he did the night before.
If alcohol damages the hippocampus, a person might find it tough to learn and to hang on to information.
CEREBELLUM-- The cerebellum is important for coordination, thoughts, and focus. An individual might have difficulty with these skills once alcohol goes into the cerebellum. After consuming alcohol, an individual's hands may be so tremulous that they cannot touch or grab things properly, and they may lose their balance and tumble.
HYPOTHALAMUS-- The hypothalamus is a little part of the brain that does a fantastic variety of the physical body's housekeeping chores. Alcohol frustrates the work of the hypothalamus. After a person consumes alcohol, blood pressure, hunger, being thirsty, and the urge to urinate increase while body temperature and heart rate decrease.
MEDULLA-- The medulla controls the physical body's unconscious actions, such as a person's heartbeat. It likewise keeps the body at the right temperature. Alcohol in fact chills the physical body. Drinking a lot of alcohol outdoors in chilly climates can trigger a person's body temperature to drop below its normal level. This unsafe condition is termed hypothermia.

Alcohol in fact cools down the body. Consuming a lot of alcohol outdoors in cold weather can trigger a person's body temperature level to drop below normal.
