Alcohol Can Create Alterations In The Operation Of The Developing BrainAlcohol can trigger modifications in the architecture and operation of the growing brain, which continues to develop into a person's mid 20s, and it may have repercussions reaching far beyond adolescence.
In adolescence, brain development is defined by dramatic changes to the brain's architecture, neural connections ("circuitry"), and physiology. These transformations in the brain alter everything from developing sexuality to emotions and cognitive ability.
Not all component parts of the juvenile brain mature concurrently, which might put a youth at a disadvantage in specific circumstances. The limbic areas of the brain mature earlier than the frontal lobes. The limbic regions control feelings and are connected with an adolescent's lowered level of sensitivity to risk. The frontal lobes are accountable for self-regulation, judgment, reasoning, analytic skills, and impulse control. Variations in maturation among parts of the brain can result in rash choices or acts and a disregard for consequences.
The way Alcohol Disturbs the Brain Alcohol alters an adolescent's brain growth in many ways. The results of minor drinking on particular brain activities are explained below. Alcohol is a central nervous system sedative. 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 of something he desires his body to do, the central nervous system-- the brain and the spine-- sends a signal to that portion of the physical body. Alcohol hinders the central nervous system, making the person think, communicate, and move less quickly.
FRONTAL LOBES -- The brain's frontal lobes are important for advanced planning, forming ideas, making decisions, and employing self-discipline.
When alcohol impairs the frontal lobes of the human brain, a person may find it hard to control his/her feelings and urges. The person may act without thinking or might even become violent. Drinking 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, an individual may have difficulty recollecting a thing she or he just learned, like a person's name or a telephone number. This can occur after just one or two drinks. Drinking a lot of alcohol rapidly can trigger a blackout-- not having the ability to recall entire events, like what exactly he or she did the night before. If alcohol harms the hippocampus, a person might find it difficult to learn and to hang on to knowledge.
CEREBELLUM-- The cerebellum is essential for coordination, to form thoughts, and attention. A person may have difficulty with these skills when alcohol enters the cerebellum. 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 fail to keep their balance and tumble.
HYPOTHALAMUS-- The hypothalamus is a little part of the brain that does a remarkable variety of the body's housekeeping tasks. Alcohol upsets the operation of the hypothalamus. After an individual drinks alcohol, blood pressure, appetite, being thirsty, and the need to urinate increase while physical body temperature and heart rate decrease.
Alcohol in fact cools down the body. Drinking a lot of alcohol outdoors in cold weather conditions can cause a person's body temperature to fall below normal.
A person may have trouble with these abilities once 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 lose their equilibrium and fall.
