Alcohol Can Cause Changes In The Architecture And Function Of The Developing Brain
Alcohol can cause modifications in the architecture and function of the growing brain, which continues to mature into an individual's mid 20s, and it might have repercussions reaching far beyond teenage years.
In adolescence, brain development is identified by remarkable modifications to the brain's structure, neuron connectivity ("electrical wiring"), and physiology. These changes in the brain alter everything from emerging sexuality to emotionality and cognitive ability.
Not all portions of the adolescent brain mature at the same time, which may put an adolescent at a disadvantage in particular circumstances. For instance, the limbic regions of the brain mature earlier than the frontal lobes. The limbic areas manage feelings and are associated with an adolescent's decreased level of sensitivity to risk. The frontal lobes are accountable for self-control, judgment, reasoning, problem-solving, and impulse control. Variations in maturation among parts of the brain can result in rash choices or acts and a neglect for consequences.
How Alcohol Affects the Brain
Alcohol affects an adolescent's brain growth in many ways. The effects of underage alcohol consumption on specific brain functions are summarized below.
Alcohol is a central nervous system sedative. Alcohol can seem to be a stimulant because, initially, it depresses the part of the brain that regulates inhibitions.
CEREBRAL CORTEX-- Alcohol hampers the cerebral cortex as it processes details from a person's senses.
CENTRAL NERVOUS SYSTEM-- When a person thinks about something he wants his body to do, the central nervous system-- the brain and the spine-- sends out a signal to that part of the physical body. Alcohol hinders the central nervous system, making the person think, communicate, and move less quickly.
FRONTAL LOBES -- The human brain's frontal lobes are necessary for advanced planning, forming ideas, decision making, and employing self-discipline.
When alcohol affects the frontal lobes of the human brain, an individual might find it tough to control his or her emotions and urges. The person might act without thinking or might even become violent. Consuming alcohol over an extended period of time can harm the frontal lobes permanently.
HIPPOCAMPUS-- The hippocampus is the part of the brain where memories are made.
Once alcohol reaches the hippocampus, an individual may have difficulty recalling a thing she or he just learned, like a name or a phone number. This can take place after just a couple of alcoholic beverages.
Drinking a great deal of alcohol rapidly can trigger a blackout-- not being able to remember entire happenings, like what exactly she or he did the night before.
If alcohol harms the hippocampus, an individual might find it difficult to learn and to hold on to information.
CEREBELLUM-- The cerebellum is essential for coordination, to form thoughts, and awareness. When alcoholism gets in the cerebellum, an individual might have difficulty with these skills. After alcoholism -4060515"> drinking alcohol, a person's hands might be so shaky that they cannot touch or get hold of things properly, and they might fail to keep their equilibrium and fall.
HYPOTHALAMUS-- The hypothalamus is a small part of the brain that does a remarkable number of the body's housekeeping tasks. Alcohol upsets the operation of the hypothalamus. After a person drinks alcohol, blood pressure, hunger, thirst, and the urge to urinate intensify while body temperature and heart rate decline.
MEDULLA-- The medulla manages the physical body's unconscious actions, such as a person's heart beat. It also keeps the body at the right temperature level. Alcohol actually cools down the physical body. Consuming a great deal of alcohol outdoors in cold weather can cause an individual's body temperature level to drop below its normal level. This hazardous condition is knowned as hypothermia.
An individual might have trouble with these abilities when alcohol gets in the cerebellum. After consuming alcohol, an individual's hands might be so unsteady that they can't touch or take hold of things normally, and they may fail to keep their equilibrium and fall.
After an individual drinks alcohol, blood pressure, hunger, thirst, and the urge to urinate increase while physical body temperature levels and heart rate decrease.
Alcohol in fact chills the physical body. Drinking a lot of alcohol outdoors in cold weather can trigger a person's physical body temperature to drop below normal.
