Alcohol can cause modifications in the structure and operation of the developing brain, which continues to develop into an individual's mid 20s, and it might have repercussions reaching far beyond teenage years.
In adolescence, brain development is characterized by remarkable changes to the brain's architecture, neuron connectivity ("electrical wiring"), and physiology. These transformations in the brain disturb everything from developing sexuality to emotions and cognitive ability.
Not all portions of the juvenile brain mature at the same time, which may put an adolescent at a disadvantage in specific situations. The limbic areas of the brain mature earlier than the frontal lobes. The limbic regions control feelings and are connected with an adolescent's reduced level of sensitivity to risk. The frontal lobes are accountable for self-regulation, judgment, reasoning, analytic skills, and impulse control. Differences in maturation among parts of the brain can result in impulsive choices or acts and a disregard for repercussions.
How Alcohol Disturbs the Human Brain
Alcohol affects a juvenile's brain growth in several ways. The repercussions of minor alcohol consumption on particular brain activities are summarized below.
Alcohol is a central nervous system depressant. Alcohol can appear to be a stimulant because, before anything else, it suppresses the portion of the human brain that regulates inhibitions.
CEREBRAL CORTEX-- Alcohol hampers the cortex as it works with details from a person's senses.
CENTRAL NERVOUS SYSTEM-- When a person thinks of something he wants his body to do, the central nervous system-- the brain and the spine-- sends out a signal to that portion of the body. Alcohol hampers the central nervous system, making the individual think, converse, and move less quickly.
FRONTAL LOBES -- The brain's frontal lobes are necessary for planning, forming ideas, making decisions, and using self-discipline.
Once alcohol impairs the frontal lobes of the human brain, a person may find it tough to control his/her emotions and impulses. The individual may act without thinking or may even become violent. Drinking alcohol over an extended period of time can damage the frontal lobes permanently.
HIPPOCAMPUS-- The hippocampus is the portion of the human brain in which memories are created.
Once alcohol gets to the hippocampus, an individual may have trouble recalling something she or he just learned, like a person's name or a telephone number. This can take place after just a couple of drinks.
Drinking a great deal of alcohol quickly can cause a blackout-- not having the ability to recall entire events, like what exactly he or she did last night.
An individual might find it difficult to learn and to hold on to information if alcohol injures the hippocampus.
CEREBELLUM-- The cerebellum is necessary for coordination, thoughts, and attention. An individual may have trouble with these skills when alcohol goes into the cerebellum. After consuming alcohol, an individual's hands may be so shaky that they can't touch or take hold of things normally, and they might lose their equilibrium and fall.
HYPOTHALAMUS-- The hypothalamus is a little part of the brain that does an incredible number of the body's housekeeping chores. Alcohol upsets the operation of the hypothalamus. After a person consumes alcohol, blood pressure, hunger, thirst, and the impulse to urinate intensify while body temperature and heart rate decline.
Alcohol actually chills the physical body. Consuming a lot of alcohol outdoors in cold weather conditions can trigger an individual's body temperature to drop below normal.
A person may have difficulty with these skills when alcohol gets in the cerebellum. After drinking alcohol, a person's hands might be so unsteady that they cannot touch or grab things properly, and they may fail to keep their equilibrium and fall.
After an individual drinks alcohol, blood pressure, appetite, thirst, and the desire to urinate increase while physical body temperature and heart rate decline.
