Alcohol Can Trigger Modifications In The Growing Brain

Alcohol can cause modifications in the architecture and operation of the growing brain, which continues to develop into an individual's mid 20s, and it may have consequences reaching far beyond adolescence.

In adolescence, brain growth is defined by dramatic modifications to the brain's architecture, neural connections ("electrical wiring"), and physiology. These transformations in the brain alter everything from emerging sexuality to emotions and cognitive ability.

Not all parts of the juvenile brain mature simultaneously, which may put an adolescent at a disadvantage in particular circumstances. For instance, the limbic areas of the brain develop earlier than the frontal lobes. The limbic areas control emotions and are connected with an adolescent's decreased sensitivity to risk. The frontal lobes are responsible for self-control, judgment, reasoning, analytic skills, and impulse control. Differences in maturation amongst parts of the brain can lead to rash decisions or acts and a neglect for repercussions.

Ways Alcohol Disturbs the Human Brain Alcohol alters a juvenile's brain growth in numerous ways. The results of juvenile drinking on specialized brain functions are detailed below. Alcohol is a central nervous system depressant. Alcohol can seem to be a stimulant because, at the start, it depresses the part of the human brain that manages inhibitions.

CEREBRAL CORTEX-- Alcohol hampers the cortex as it processes details 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 portion of the physical body. alcohol hinders the central nervous system, making the person think, converse, and move less quickly.

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

An individual might find it difficult to manage his or her feelings and urges when alcohol affects the frontal lobes of the brain. The individual may act without thinking or may even become violent. Consuming alcohol over an extended period of time can harm the frontal lobes permanently.

HIPPOCAMPUS-- The hippocampus is the part of the brain in which memories are generated. Once alcohol reaches the hippocampus, an individual might have difficulty recalling a thing he or she just learned, such as a name or a phone number. This can occur after just one or two alcoholic beverages. Drinking a great deal of alcohol quickly can trigger a blackout-- not being able to recollect whole incidents, such as what exactly he or she did the night before. If alcohol harms the hippocampus, a person might find it tough to learn and to hold on to information.

CEREBELLUM-- The cerebellum is essential for coordination, ideas, and attention. When alcohol goes into the cerebellum, an individual may have trouble with these abilities. After drinking alcohol, an individual's hands may be so shaky that they cannot touch or get hold of things normally, and they might lose their equilibrium and tumble.

HYPOTHALAMUS-- The hypothalamus is a little part of the brain that does an incredible variety of the physical 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 physical body temperature and heart rate decline.

Alcohol actually chills the physical body. Drinking a lot of alcohol outdoors in cold weather can trigger a person's physical body temperature to drop below normal.

A person may have trouble with these abilities once alcohol gets in the cerebellum. After consuming alcohol, a person's hands might be so tremulous that they cannot touch or get hold of things normally, and they might lose their balance and fall.

After a person drinks alcohol, blood pressure, appetite, thirst, and the desire to urinate increase while body temperature and heart rate decrease.

Alcohol in fact chills the physical body. drinking a lot of alcohol outdoors in cold weather can trigger a person's body temperature to drop below normal.
