Alcohol Consumption Can Trigger Alterations In The Architecture And Operation Of The Developing Brain

July 19, 2018

Alcohol can cause changes in the structure and operation of the growing brain, which continues to develop into a person’s mid 20s, and it may have repercussions reaching far beyond teenage years.

In adolescence, brain growth is characterized by remarkable modifications to the brain’s architecture, neural connections (“electrical wiring”), and physiology. These transformations in the brain disturb everything from emerging sexuality to emotions and cognitive ability.

relapsed of the juvenile brain mature at the same time, which may put a youth at a disadvantage in certain circumstances. The limbic regions of the brain mature earlier than the frontal lobes. The limbic areas regulate feelings and are related to a juvenile’s lowered sensitivity to risk. The frontal lobes are accountable for self-control, judgment, reasoning, analytic skills, and impulse control. Differences in maturation among parts of the brain can lead to rash decisions or acts and a neglect for consequences.

How Alcohol Alters the Human Brain
Alcohol affects a juvenile’s brain development in numerous ways. The consequences of adolescent drinking on specific brain activities are explained below.
Alcohol is a central nervous system sedative. alcohol dependence can appear to be a stimulant because, initially, it suppresses the portion of the brain that controls inhibitions.

CORTEX– detoxification hinders the cerebral cortex as it processes information from a person’s senses.

CENTRAL NERVOUS SYSTEM– When an individual thinks about something he wants his body to do, the central nervous system– the brain and the spinal cord– sends a signal to that portion of the body. Alcohol hinders the central nervous system, making the individual think, converse, and move slower.

FRONTAL LOBES – The brain’s frontal lobes are very important for organizing, creating ideas, decision making, and exercising self-discipline.

Once alcohol impacts the frontal lobes of the brain, a person may find it tough to control his/her emotions and impulses. The person might act without thinking or may even become violent.

HIPPOCAMPUS– The hippocampus is the portion of the human brain in which memories are created.
When alcohol gets to the hippocampus, an individual might have difficulty recalling a thing he or she just learned, like a name or a phone number. This can happen after just a couple of drinks.
Drinking a great deal of alcohol rapidly can cause a blackout– not having the ability to recall entire happenings, such as what exactly he or she did last night.

If alcohol injures the hippocampus, an individual may find it tough to learn and to hold on to knowledge.

CEREBELLUM– The cerebellum is very important for coordination, thoughts, and awareness. A person may have trouble with these skills when alcohol goes into the cerebellum. After drinking alcohol, an individual’s hands may be so unsteady that they cannot touch or get hold of things properly, and they might lose their equilibrium and fall.

HYPOTHALAMUS– The hypothalamus is a small part of the brain that does an incredible number of the physical body’s housekeeping tasks. Alcohol frustrates the work of the hypothalamus. After a person consumes alcohol, blood pressure, hunger, being thirsty, and the impulse to urinate intensify while body temperature and heart rate decline.

MEDULLA– The medulla manages the body’s automatic actions, such as an individual’s heart beat. It also keeps the body at the ideal temperature. Alcohol in fact cools down the body. Drinking a lot of alcohol outdoors in cold weather can cause an individual’s physical body temperature to fall below its normal level. This unsafe condition is knowned as hypothermia.

An individual might have trouble with these skills once alcohol enters the cerebellum. After consuming alcohol , an individual’s hands may be so tremulous that they cannot touch or take hold of things normally, and they may lose their equilibrium and fall.

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

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