Alcohol Can Cause Changes In The Architecture And Function Of The Developing Brain
Alcohol can cause alterations in the structure and operation of the developing brain, which continues to grow into an individual's mid 20s, and it might have consequences reaching far beyond adolescence.
In adolescence, brain development is characterized by dramatic changes to the brain's structure, neural connections ("electrical wiring"), and physiology. alcoholic in the brain affect everything from emerging sexuality to emotions and judgment.
Not all portions of the juvenile brain mature at the same time, which may put an adolescent at a disadvantage in specific circumstances. For example, the limbic regions of the brain develop earlier than the frontal lobes. The limbic areas manage feelings and are connected with an adolescent's reduced sensitivity to risk. The frontal lobes are responsible for self-regulation, judgment, reasoning, analytic skills, and impulse control. Variations in maturation among parts of the brain can result in impulsive choices or acts and a disregard for consequences.
The way Alcohol Affects the Human Brain
Alcohol affects an adolescent's brain development in many ways. The effects of juvenile drinking on particular brain functions are detailed 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 brain that regulates inhibitions.
CORTEX-- Alcohol hampers the cortex as it processes information from an individual's senses.
CENTRAL NERVOUS SYSTEM-- When an individual thinks about something he wants his body to undertake, 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, speak, and move less quickly.
FRONTAL LOBES -- The brain's frontal lobes are very important for advanced planning, forming ideas, making decisions, and using self-discipline.
Once alcohol impairs the frontal lobes of the brain, a person may find it difficult to control his or her feelings and impulses. The person may act without thinking or may even become violent. Consuming alcohol over an extended period of time can injure the frontal lobes permanently.
HIPPOCAMPUS-- The hippocampus is the part of the human brain where memories are created.
Once alcohol gets to the hippocampus, an individual may have difficulty recollecting something she or he just learned, such as a name or a phone number. This can occur after just one or two drinks.
Drinking a great deal of alcohol quickly can trigger a blackout-- not being able to remember whole occurrences, such as what exactly he or she did the night before.
A person may find it hard to learn and to hold on to information if alcohol injures the hippocampus.
CEREBELLUM-- The cerebellum is necessary for coordination, thoughts, and attention. An individual might have difficulty with these abilities when alcohol gets in the cerebellum. After consuming alcohol, an individual's hands might be so tremulous that they can't touch or grab things normally, and they may fail to keep their equilibrium and fall.
HYPOTHALAMUS-- The hypothalamus is a little part of the brain that does an amazing number of the body's housekeeping tasks. Alcohol upsets the operation of the hypothalamus. After alcoholic consumes alcohol, blood pressure, appetite, being thirsty, and the urge to urinate increase while body temperature level and heart rate decrease.
MEDULLA-- The medulla controls the body's automatic actions, like a person's heart beat. It also keeps the physical body at the best temperature. Alcohol really cools down the physical body. Consuming a great deal of alcohol outdoors in cold climates can trigger a person's body temperature to drop below normal. This dangerous condition is called hypothermia.
A person may have trouble with these abilities when alcohol goes into the cerebellum. After drinking alcohol, a person's hands may be so tremulous that they can't touch or take hold of things properly, and they may fail to keep their equilibrium and tumble.
After an individual drinks alcohol, blood pressure, appetite, 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 can cause a person's body temperature to drop below normal.
