Alcohol Consumption Can Create Modifications In The Structure Of The Maturing Brain

Alcohol consumption can cause changes in the structure and function of the developing brain, which continues to grow into a person's mid 20s, and it might have repercussions reaching far beyond adolescence.

In adolescence, brain development is characterized by remarkable changes to the brain's architecture, neuron connectivity ("circuitry"), 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 might put a youth at a disadvantage in specific circumstances. For example, the limbic areas of the brain develop quicker than the frontal lobes. The limbic areas manage feelings and are connected with an adolescent's reduced 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 result in rash choices or acts and a neglect for repercussions.

How Alcohol Alters the Human Brain Alcohol alters an adolescent's brain growth in several ways. The effects of adolescent drinking on particular brain activities are summarized below. Alcohol is a central nervous system sedative drug. Alcohol can seem to be a stimulant because, before anything else, it depresses the part of the brain that regulates inhibitions.

CEREBRAL CORTEX-- Alcohol impedes the cortex as it works with details from an individual's senses.

CENTRAL NERVOUS SYSTEM-- When an individual thinks of something he wants his body to undertake, the central nervous system-- the brain and the spine-- sends out a signal to that part of the physical body. Alcohol impedes the central nervous system, making the individual think, communicate, and move more slowly.

FRONTAL LOBES -- The human brain's frontal lobes are very important for organizing, forming ideas, making decisions, and employing self-control.

Once alcohol impacts the frontal lobes of the brain, an individual might find it tough to control his or her feelings and impulses. The individual might act without thinking or might even get violent. drinking alcohol over an extended period of time can injure the frontal lobes forever.

HIPPOCAMPUS-- The hippocampus is the part of the brain in which memories are created. Once alcohol reaches the hippocampus, a person might have difficulty recalling something she or he just learned, such as a name or a phone number. This can take place after just a couple of drinks. Drinking a lot of alcohol rapidly can cause a blackout-- not having the ability to remember entire events, like what she or he did the night before. If alcohol harms the hippocampus, an individual may find it tough to learn and to hold on to knowledge.

CEREBELLUM-- The cerebellum is essential for coordination, thoughts, and awareness. When alcohol enters the cerebellum, an individual might have trouble with these skills. After consuming alcohol, an individual's hands might be so unsteady that they can't touch or grab things normally, and they may fail to keep their balance and tumble.

HYPOTHALAMUS-- The hypothalamus is a small part of the brain that does an amazing variety of the physical body's housekeeping tasks. Alcohol upsets the work of the hypothalamus. After a person consumes alcohol, blood pressure, hunger, thirst, and the impulse to urinate increase while physical body temperature level and heart rate decrease.

MEDULLA-- The medulla controls the body's automatic actions, such as an individual's heart beat. It also keeps the body at the best temperature. Alcohol actually chills the body. Drinking a great deal of alcohol outdoors in cold weather can cause a person's physical body temperature level to drop below its normal level. This unsafe condition is termed hypothermia.

An individual may have difficulty with these skills when alcohol enters the cerebellum. After drinking alcohol, a person's hands might be so shaky that they can't touch or grab things properly, and they might fail to keep their equilibrium and tumble.

After a person alcoholic beverages alcohol, blood pressure, hunger, thirst, and the desire to urinate increase while physical body temperature levels and heart rate decline.

Alcohol actually cools down the physical body. Drinking a lot of alcohol outdoors in cold weather conditions can trigger a person's physical body temperature level to fall below normal.
