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 may have repercussions reaching far beyond teenage years.
In adolescence, brain development is defined by dramatic changes to the brain's architecture, neural connections ("electrical wiring"), and physiology. These changes in the brain disturb everything from emerging sexuality to emotionality and judgment.
problem of the juvenile brain mature simultaneously, which might put an adolescent at a disadvantage in specific situations. The limbic regions of the brain mature earlier than the frontal lobes. The limbic regions regulate emotions and are associated with an adolescent's decreased sensitivity to risk. The frontal lobes are accountable for self-regulation, judgment, reasoning, analytic skills, and impulse control. Variations in maturation amongst parts of the brain can lead to impulsive decisions or acts and a disregard for consequences.
How Alcohol Alters the Human Brain
Alcohol affects a juvenile's brain growth in numerous ways. The effects of minor alcohol consumption on specialized brain functions are explained below.
Alcohol is a central nervous system sedative. alcoholism can appear to be a stimulant because, to begin with, it suppresses the part of the brain that manages inhibitions.
CEREBRAL CORTEX-- Alcohol slows down the cerebral cortex as it works with information from an individual's senses.
CENTRAL NERVOUS SYSTEM-- When a person thinks of something he desires his body to undertake, the central nervous system-- the brain and the spine-- sends a signal to that part of the body. Alcohol impedes the central nervous system, making the individual think, converse, and move less quickly.
FRONTAL LOBES -- The human brain's frontal lobes are necessary for planning, forming ideas, making decisions, and using self-discipline.
Once alcohol impairs the frontal lobes of the brain, an individual may find it tough to control his/her emotions and urges. The individual may act without thinking or might even become violent. Consuming alcohol over an extended period of time can injure the frontal lobes forever.
HIPPOCAMPUS-- The hippocampus is the portion of the brain in which memories are created.
Once alcohol gets to the hippocampus, a person may have trouble recollecting a thing he or she just learned, like a name or a phone number. This can occur after just a couple of drinks.
Drinking a lot of alcohol rapidly can cause a blackout-- not being able to remember entire events, such as what she or he did last night.
A person might find it difficult to learn and to hold on to information if alcohol harms the hippocampus.
CEREBELLUM-- The cerebellum is important for coordination, thoughts, and awareness. When alcohol enters the cerebellum, an individual may have difficulty with these skills. After consuming alcohol, an individual's hands might be so unsteady that they can't touch or get hold of things normally, and they may lose their equilibrium and fall.
HYPOTHALAMUS-- The hypothalamus is a small part of the brain that does a remarkable variety of the body's housekeeping tasks. Alcohol frustrates the operation of the hypothalamus. After a person drinks alcohol, blood pressure, hunger, thirst, and the need to urinate increase while physical body temperature and heart rate decline.
Alcohol actually chills the physical body. Consuming alcoholism of alcohol outdoors in cold weather can cause a person's physical body temperature level to drop below normal.
