Alcohol Can Create Changes In The Growing BrainAlcohol can trigger alterations in the structure and function of the growing brain, which continues to develop into a person's mid 20s, and it might have consequences reaching far beyond adolescence.
In adolescence, brain growth is defined by remarkable changes to the brain's structure, neuron connectivity ("circuitry"), and physiology. These changes in the brain alter everything from developing sexuality to emotions and cognitive ability.
Not all component parts of the juvenile brain mature at the same time, which may put a youth at a disadvantage in certain circumstances. For instance, the limbic regions of the brain mature quicker than the frontal lobes. The limbic areas manage feelings and are connected with an adolescent's reduced 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 decisions or acts and a neglect for consequences.
Ways Alcohol Affects the Human Brain Alcohol affects an adolescent's brain growth in many ways. The consequences of juvenile drinking on particular brain functions are discussed below. alcohol is a central nervous system sedative drug. Alcohol can appear to be a stimulant because, at the start, it depresses the part of the brain that regulates inhibitions.
CORTEX-- Alcohol hinders 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 undertake, the central nervous system-- the brain and the spinal cord-- sends a signal to that part of the physical body. Alcohol slows down the central nervous system, making the individual think, speak, and move slower.
FRONTAL LOBES -- The human brain's frontal lobes are very important for organizing, creating ideas, making decisions, and employing self-control.
An individual may find it difficult to manage his or her feelings and urges once alcohol impacts the frontal lobes of the brain. The person may act without thinking or might even become violent. Drinking alcohol over a long period of time can harm the frontal lobes forever.
HIPPOCAMPUS-- The hippocampus is the part of the brain where memories are created. When alcohol gets to the hippocampus, an individual may have trouble recollecting a thing he or she just learned, like a name or a phone number. This can happen after just one or two drinks. Drinking a lot of alcohol quickly can trigger a blackout-- not being able to recollect whole occurrences, such as what he or she did last night. If alcohol damages the hippocampus, a person might find it difficult to learn and to hold on to knowledge.
CEREBELLUM-- The cerebellum is essential for coordination, to form thoughts, and awareness. An individual might have trouble with these abilities when alcohol goes into the cerebellum. After drinking alcohol, an individual's hands might be so tremulous that they cannot touch or grab things normally, and they might fail to keep their balance and tumble.
HYPOTHALAMUS-- The hypothalamus is a small part of the brain that does a fantastic number of the body's housekeeping chores. Alcohol upsets the work of the hypothalamus. After an individual drinks alcohol, blood pressure, appetite, being thirsty, and the impulse to urinate intensify while physical body temperature and heart rate decrease.
Alcohol actually chills the body. Drinking a lot of alcohol outdoors in cold weather can cause an individual's body temperature to drop below normal.
A person might have difficulty with these abilities when alcohol enters the cerebellum. After consuming alcohol, an individual's hands may be so unsteady that they can't touch or get hold of things normally, and they may fail to keep their equilibrium and tumble.
After a person drinks alcohol, blood pressure, appetite, thirst, and the desire to urinate increase while physical body temperature levels and heart rate decrease.
