Alcohol Consumption Can Cause Alterations In The Architecture And Function Of The Growing Brain
Alcohol can cause alterations in the architecture and function of the blossoming brain, which continues to develop into an individual's mid 20s, and it may have repercussions reaching far beyond teenage years.
In adolescence, brain growth is characterized by dramatic changes to the brain's architecture, neural connections ("circuitry"), and physiology. These changes in the brain disturb everything from emerging sexuality to emotions and cognitive ability.
Not all parts of the adolescent brain mature at the same time, which may put a juvenile at a disadvantage in certain scenarios. The limbic regions of the brain mature earlier than the frontal lobes.
How Alcohol Affects the Brain
Alcohol alters an adolescent's brain growth in many ways. The effects of minor alcohol consumption on specialized brain functions are summarized below.
Alcohol is a central nervous system sedative drug. Alcohol can appear to be a stimulant because, initially, it suppresses the portion of the brain that manages inhibitions.
CEREBRAL CORTEX-- Alcohol impedes the cortex as it works with details from a person's senses.
CENTRAL NERVOUS alcoholism -- When a person thinks about something he desires his body to do, the central nervous system-- the brain and the spine-- sends out a signal to that part of the physical body. Alcohol hinders the central nervous system, making the person think, communicate, and move less quickly.
FRONTAL LOBES -- The human brain's frontal lobes are very important for planning, creating ideas, making decisions, and employing self-discipline.
Once alcohol impacts the frontal lobes of the human brain, an individual may find it hard to manage his or her emotions and impulses. The person may act without thinking or may even become violent. Consuming alcohol over a long period of time can damage the frontal lobes forever.
HIPPOCAMPUS-- The hippocampus is the part of the brain where memories are generated.
When alcohol gets to the hippocampus, a person might have difficulty remembering a thing she or he just learned, like a person's name or a telephone number. This can happen after just a couple of alcoholic beverages.
Drinking a lot of alcohol rapidly can trigger a blackout-- not being able to remember whole occurrences, like what she or he did the night before.
A person may find it hard to learn and to hold on to knowledge if alcohol harms the hippocampus.
CEREBELLUM-- The cerebellum is necessary for coordination, thoughts, and focus. An individual might have difficulty with these skills once alcohol goes into the cerebellum. After consuming alcohol, an individual's hands might be so tremulous that they cannot touch or get hold of things normally, and they might fail to keep their equilibrium and fall.
HYPOTHALAMUS-- The hypothalamus is a little part of the brain that does an incredible number of the body's housekeeping chores. Alcohol frustrates the work of the hypothalamus. After an individual drinks alcohol, blood pressure, hunger, being thirsty, and the need to urinate intensify while body temperature and heart rate decline.
MEDULLA-- The medulla manages the body's automatic actions, such as a person's heart beat. It also keeps the physical body at the best temperature level. Alcohol in fact chills the physical body. Consuming a great deal of alcohol outdoors in chilly climates can trigger a person's body temperature level to fall below normal. This harmful situation is called hypothermia.
A person might have trouble with these skills once alcohol goes into the cerebellum. After consuming alcohol, a person's hands may be so shaky that they cannot touch or grab things normally, and they might fail to keep their balance and fall.
After a person drinks alcohol, blood pressure, hunger, thirst, and the urge to urinate increase while body temperature and heart rate decline.
Alcohol in fact cools down the physical body. Drinking a lot of alcohol outdoors in cold weather conditions can trigger an individual's body temperature level to fall below normal.
