Alcohol Can Trigger Alterations In The Structure And Operation Of The Developing Brain

Alcohol can trigger alterations in the structure and operation of the growing brain, which continues to develop into an individual's mid 20s, and it might have repercussions reaching far beyond adolescence.

In adolescence, brain growth is identified by dramatic changes to the brain's structure, neuron connectivity ("circuitry"), and physiology. These changes in the brain affect everything from developing sexuality to emotions and judgment.

need to answer a troublesome question: . . .
what causes alcoholism ?
Not all parts of the adolescent brain mature at the exact same time, which might put a juvenile at a disadvantage in particular circumstances. The limbic areas of the brain develop sooner than the frontal lobes.

Ways Alcohol Affects the Brain
Alcohol disturbs a juvenile's brain growth in several ways. The consequences of minor alcohol consumption on specific brain activities are detailed below.
Alcohol is a central nervous system sedative drug. Alcohol can appear to be a stimulant because, at the start, it depresses the portion of the brain that manages inhibitions.

CEREBRAL CORTEX-- Alcohol hinders the cerebral cortex as it processes details from an individual's senses.

CENTRAL NERVOUS SYSTEM-- When a person thinks of 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 person think, speak, and move more slowly.

FRONTAL LOBES -- The human brain's frontal lobes are necessary for planning, creating concepts, making decisions, and using self-discipline.

An individual might find it hard to control his or her feelings and urges when alcohol impairs the frontal lobes of the brain. The individual 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 portion of the human brain in which memories are created.
Once alcohol reaches the hippocampus, a person might have difficulty recollecting a thing she or he just learned, like a person's name or a phone number. This can take place after just one or two drinks.
Drinking a great deal of alcohol rapidly can trigger a blackout-- not having the ability to recall whole incidents, like what exactly he or she did last night.
An individual might find it hard to learn and to hold on to information if alcohol harms the hippocampus.

CEREBELLUM-- The cerebellum is important for coordination, ideas, and focus. A person might have trouble with these skills when alcohol gets in the cerebellum. After drinking alcohol, an individual's hands might be so shaky that they can't touch or grab things normally, and they might lose their equilibrium 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 a person drinks alcohol, blood pressure, hunger, being thirsty, and the impulse to urinate intensify while physical body temperature level and heart rate decline.

Alcohol in fact cools down the physical body. Drinking a lot of alcohol outdoors in cold weather can cause a person's body temperature to drop below normal.


An individual may have difficulty with these skills when alcohol goes into the cerebellum. After consuming alcohol, an individual's hands might be so unsteady that they cannot touch or take hold of things properly, and they might lose their equilibrium and fall.

After an individual drinks alcohol, blood pressure, hunger, thirst, and the desire to urinate increase while body temperature levels and heart rate decline.

Alcohol in fact cools down the body. Consuming a lot of alcohol outdoors in cold weather conditions can trigger an individual's body temperature to drop below normal.
