Modifications In The Growing Brain from Alcohol?Alcohol consumption can cause alterations in the architecture and operation of the blossoming brain, which continues to mature into a person's mid 20s, and it may have repercussions reaching far beyond adolescence.
In adolescence, brain growth is defined by dramatic changes to the brain's structure, neural connections ("electrical wiring"), and physiology. These changes in the brain alter everything from emerging sexuality to emotions and cognitive ability.
Not all parts of the adolescent brain mature simultaneously, which may put a youth at a disadvantage in specific situations. The limbic regions of the brain mature earlier than the frontal lobes. The limbic regions control emotions and are connected with a juvenile's decreased level of sensitivity to risk. The frontal lobes are accountable for self-control, judgment, reasoning, analytic skills, and impulse control. Differences in maturation amongst parts of the brain can result in careless decisions or actions and a neglect for repercussions.
The way Alcohol Alters the Brain Alcohol disturbs a juvenile's brain growth in numerous ways. The results of adolescent alcohol consumption on specialized brain activities are detailed below. Alcohol is a central nervous system sedative. Alcohol can appear to be a stimulant because, to begin with, it depresses the portion of the brain that controls inhibitions.
CEREBRAL CORTEX-- Alcohol hinders the cerebral cortex as it works with information from a person'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 spinal cord-- sends a signal to that part of the body. Alcohol hampers the central nervous system, making the person think, speak, and move slower.
FRONTAL LOBES -- The human brain's frontal lobes are essential for organizing, forming concepts, making decisions, and exercising self-discipline.
When alcohol impairs the frontal lobes of the human brain, a person may find it difficult to control his or her feelings and urges. The person may act without thinking or may even get violent. Consuming alcohol over an extended period of time can injure the frontal lobes permanently.

alcoholism is not a disease
HIPPOCAMPUS-- The hippocampus is the portion of the human brain in which memories are created. Once alcohol reaches the hippocampus, an individual might have difficulty recollecting something he or she just learned, such as a name or a phone number. This can occur after just one or two drinks. Drinking a lot of alcohol rapidly can cause a blackout-- not having the ability to recollect entire happenings, like what he or she did last night. A person may find it difficult to learn and to hold on to knowledge if alcohol harms the hippocampus.
CEREBELLUM-- The cerebellum is essential for coordination, to form thoughts, and awareness. When alcohol goes into the cerebellum, an individual may have difficulty with these skills. After drinking alcohol, an individual's hands may be so unsteady that they cannot touch or get hold of things properly, and they might lose their balance and fall.
HYPOTHALAMUS-- The hypothalamus is a little part of the brain that does an amazing variety of the body's housekeeping tasks. Alcohol frustrates the operation of the hypothalamus. After a person consumes alcohol, blood pressure, hunger, thirst, and the impulse to urinate increase while body temperature level and heart rate decrease.
Alcohol actually chills the physical body. Drinking a lot of alcohol outdoors in cold weather can trigger an individual's body temperature to fall below normal.
An individual might have trouble with these abilities once alcohol gets in the cerebellum. After drinking alcohol, an individual's hands may be so unsteady that they cannot touch or get hold of things properly, and they may lose their equilibrium and tumble.
After an individual drinks alcohol, blood pressure, appetite, being thirsty, and the desire to urinate increase while physical body temperature levels and heart rate decline.
Alcohol in fact cools down the physical body. Consuming a lot of alcohol outdoors in cold weather can cause an individual's physical body temperature to fall below normal.
