Alcohol consumption can cause alterations in the architecture and operation of the growing brain, which continues to develop into an individual's mid 20s, and it might have consequences reaching far beyond teenage years.
In adolescence, brain growth is identified by remarkable modifications to the brain's structure, neuron connectivity ("circuitry"), and physiology. These changes in the brain alter everything from developing sexuality to emotionality and judgment.
Not all portions of the adolescent brain mature simultaneously, which might put a juvenile at a disadvantage in particular scenarios. For instance, the limbic regions of the brain develop quicker than the frontal lobes. The limbic regions control emotions and are connected with an adolescent's decreased sensitivity to risk. The frontal lobes are accountable for self-control, judgment, reasoning, analytic skills, and impulse control. Differences in maturation among parts of the brain can lead to rash choices or acts and a neglect for repercussions.
Ways Alcohol Alters the Human Brain Alcohol alters an adolescent's brain growth in many ways. The consequences of adolescent alcohol consumption on particular brain functions are detailed below. Alcohol is a central nervous system sedative. Alcohol can seem to be a stimulant because, before anything else, it suppresses the part of the brain that regulates inhibitions.
CEREBRAL CORTEX-- Alcohol slows down the cortex as it processes information from a person's senses.
CENTRAL NERVOUS SYSTEM-- When a person thinks about something he desires his body to do, the central nervous system-- the brain and the spine-- sends out a signal to that portion 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 important for planning, creating concepts, decision making, and exercising self-discipline.
Once alcohol impairs the frontal lobes of the human brain, an individual might find it difficult to manage his/her feelings and impulses. The person may act without thinking or might even become violent. Drinking alcohol over a long period of time can damage the frontal lobes permanently.
HIPPOCAMPUS-- The hippocampus is the part of the brain where memories are generated. When alcohol gets to the hippocampus, an individual might have trouble recalling something he or she just learned, like a person's name or a phone number. This can occur after just one or two alcoholic beverages. drinking a lot of alcohol quickly can trigger a blackout-- not having the ability to remember whole happenings, such as what exactly she or he did the night before. An individual might find it difficult to learn and to hold on to knowledge if alcohol harms the hippocampus.
CEREBELLUM-- The cerebellum is essential for coordination, thoughts, and focus. When alcohol goes into the cerebellum, a person may have difficulty with these abilities. After drinking alcohol, a person's hands might be so unsteady that they can't touch or get hold of things properly, and they may lose their balance and tumble.
HYPOTHALAMUS-- The hypothalamus is a little part of the brain that does an incredible variety of the body's housekeeping tasks. Alcohol frustrates the work of the hypothalamus. After an individual drinks alcohol, blood pressure, appetite, thirst, and the urge to urinate intensify while physical body temperature level and heart rate decrease.
Alcohol in fact cools down the physical body. Drinking a lot of alcohol outdoors in cold weather can trigger an individual's physical body temperature to fall below normal.
An individual may have difficulty with these skills when alcohol goes into the cerebellum. After consuming alcohol, a person's hands might be so tremulous that they cannot touch or take hold of things normally, and they might fail to keep their equilibrium and fall.
After a person alcoholic beverages alcohol, blood pressure, hunger, being thirsty, and the urge to urinate increase while physical body temperature levels and heart rate decline.
