Alcohol Use Can Create Changes In The Growing BrainAlcohol can trigger modifications in the structure and operation of the growing brain, which continues to mature into a person's mid 20s, and it may have consequences reaching far beyond teenage years.
In adolescence, brain growth is defined by dramatic changes to the brain's architecture, neural connections ("electrical wiring"), and physiology. These changes in the brain alter everything from emerging sexuality to emotionality and judgment.
Not all component parts of the juvenile brain mature concurrently, which might put a youth at a disadvantage in certain circumstances. The limbic areas of the brain mature earlier than the frontal lobes. The limbic areas control emotions and are connected with a juvenile's reduced sensitivity to risk. The frontal lobes are accountable for self-control, judgment, reasoning, problem-solving, and impulse control. Differences in maturation amongst parts of the brain can lead to rash choices or acts and a neglect for consequences.
How Alcohol Alters the Human Brain Alcohol alters an adolescent's brain growth in numerous ways. The consequences of underage alcohol consumption on specialized brain activities are explained below. Alcohol is a central nervous system depressant. Alcohol can seem to be a stimulant because, to begin with, it depresses the part of the human brain that regulates inhibitions.

CORTEX-- Alcohol hinders the cortex as it processes information from an individual's senses.
CENTRAL NERVOUS SYSTEM-- When an individual thinks about something he wants his body to do, the central nervous system-- the brain and the spinal cord-- sends out a signal to that portion of the physical body. Alcohol hampers the central nervous system, making the individual think, converse, and move more slowly.
FRONTAL LOBES -- The human brain's frontal lobes are very important for organizing, forming concepts, decision making, and employing self-discipline.
An individual may find it hard to manage his or her feelings and urges when alcohol impairs the frontal lobes of the brain. The person might act without thinking or may even get violent. Consuming alcohol over a long period of time can harm the frontal lobes permanently.
HIPPOCAMPUS-- The hippocampus is the portion of the brain in which memories are generated. Once alcohol gets to the hippocampus, a person may have trouble recalling something she or he just learned, like a person's name or a phone number. This can occur after just a couple of alcoholic beverages. Drinking a great deal of alcohol quickly can trigger a blackout-- not having the ability to remember whole happenings, such as what exactly she or he did last night. An individual may find it difficult to learn and to hold on to knowledge if alcohol damages the hippocampus.
CEREBELLUM-- The cerebellum is essential for coordination, ideas, and attention. A person may have trouble with these skills when alcohol gets in the cerebellum. After drinking alcohol, a person's hands may be so unsteady that they can't touch or get hold of things normally, and they may lose their balance and tumble.
HYPOTHALAMUS-- The hypothalamus is a little part of the brain that does a remarkable number of the physical body's housekeeping tasks. Alcohol frustrates the operation of the hypothalamus. After an individual drinks alcohol, blood pressure, hunger, thirst, and the impulse to urinate intensify while body temperature and heart rate decrease.
MEDULLA-- The medulla manages the physical body's unconscious actions, such as an individual's heartbeat. It likewise keeps the physical body at the right temperature. Alcohol actually chills the physical body. Consuming a lot of alcohol outdoors in chilly climates can trigger a person's body temperature level to fall below normal. This hazardous situation is termed hypothermia.
An individual might have difficulty with these abilities once alcohol enters the cerebellum. After drinking alcohol, an individual's hands might be so shaky that they can't touch or get hold of things properly, and they may fail to keep their equilibrium and tumble.
After an individual alcoholic beverages alcohol, blood pressure, hunger, thirst, and the desire to urinate increase while body temperature levels and heart rate decline.
