Alcohol Consumption Can Cause Alterations In The Structure And Function Of The Growing Brain
Alcohol consumption can cause changes in the architecture and operation of the growing brain, which continues to mature into a person's mid 20s, and it might have repercussions reaching far beyond adolescence.
In adolescence, brain growth is characterized by remarkable modifications to the brain's architecture, neuron connectivity ("circuitry"), and physiology. These changes in the brain affect everything from emerging sexuality to emotions and cognitive ability.
Not all parts of the juvenile brain mature at the exact same time, which may put an adolescent at a disadvantage in particular situations. The limbic areas of the brain develop sooner than the frontal lobes.
How Alcohol Affects the Human Brain
Alcohol affects a juvenile's brain development in several ways. The repercussions of underage alcohol consumption on particular brain functions are summarized below.
Alcohol is a central nervous system sedative. Alcohol can seem to be a stimulant because, to begin with, it suppresses the portion of the brain that controls inhibitions.
CORTEX-- Alcohol impedes the cerebral cortex as it processes 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 portion of the physical body. alcoholism impedes the central nervous system, making the person think, converse, and move less quickly.
FRONTAL LOBES -- The brain's frontal lobes are necessary for planning, creating concepts, decision making, and exercising self-control.
When alcohol impacts the frontal lobes of the human brain, a person may find it tough to control his/her feelings and urges. The individual might act without thinking or might even become violent. Consuming alcohol over a long period of time can damage the frontal lobes forever.
HIPPOCAMPUS-- The hippocampus is the part of the brain in which memories are created.
Once alcoholism gets to the hippocampus, an individual might have trouble remembering something she or he just learned, like a 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 being able to recall entire incidents, like what he or she did the night before.
If alcohol injures the hippocampus, a person may find it tough to learn and to hold on to knowledge.
CEREBELLUM-- The cerebellum is important for coordination, ideas, and focus. An individual might have difficulty with these abilities once alcohol gets in the cerebellum. After drinking alcohol, a person's hands might be so tremulous that they can't touch or take hold of things properly, and they might fail to keep their balance and fall.
HYPOTHALAMUS-- The hypothalamus is a small part of the brain that does a remarkable number of the physical body's housekeeping tasks. Alcohol upsets the work of the hypothalamus. After an individual drinks alcohol, blood pressure, appetite, thirst, and the impulse to urinate increase while physical body temperature and heart rate decrease.
MEDULLA-- The medulla controls the body's unconscious actions, like an individual's heartbeat. It also keeps the body at the right temperature. Alcohol really chills the body. Consuming a lot of alcohol outdoors in cold weather can trigger an individual's physical body temperature level to drop below its normal level. alcohol dependence is called hypothermia.
An individual may have difficulty with these skills when alcohol enters the cerebellum. After consuming alcohol, a person's hands might be so tremulous that they cannot touch or grab things normally, and they may fail to keep their equilibrium and tumble.
After a person drinks alcohol, blood pressure, hunger, being thirsty, and the urge to urinate increase while body temperature levels and heart rate decrease.
Alcohol in fact cools down the physical body. Consuming a lot of alcohol outdoors in cold weather conditions can trigger a person's body temperature level to fall below normal.
