Alcohol can trigger alterations in the structure and function of the blossoming brain, which continues to grow into an individual’s mid 20s, and it might have repercussions reaching far beyond teenage years.
In adolescence, brain growth is characterized by remarkable modifications to the brain’s structure, neuron connectivity (“circuitry”), and physiology. These transformations in the brain alter everything from developing sexuality to emotions and cognitive ability.
Not all parts of the adolescent brain mature at the exact same time, which might put an adolescent at a disadvantage in particular circumstances. The limbic regions of the brain develop sooner than the frontal lobes.
Ways Alcohol Alters the Human Brain
Alcohol alters an adolescent’s brain growth in several ways. The effects of minor alcohol consumption on specialized brain activities are explained below.
Alcohol is a central nervous system depressant. Alcohol can seem to be a stimulant because, before anything else, it depresses the part of the human brain that governs inhibitions.
CEREBRAL CORTEX– Alcohol hinders the cerebral cortex as it processes information from a person’s senses.
CENTRAL NERVOUS SYSTEM– When a person thinks of something he wants his body to do, the central nervous system– the brain and the spinal cord– sends a signal to that part of the physical body. Alcohol hinders the central nervous system, making the individual think, converse, and move less quickly.
FRONTAL LOBES – The brain’s frontal lobes are very important for organizing, creating ideas, decision making, and exercising self-control.
A person may find it difficult to control his or her emotions and urges when alcohol affects the frontal lobes of the brain. The person may act without thinking or may even become violent. Drinking alcohol over a long period of time can damage the frontal lobes permanently.
HIPPOCAMPUS– The hippocampus is the part of the human brain in which memories are made.
Once alcohol gets to the hippocampus, a person might have trouble recalling a thing she or he just learned, like a name or a telephone number. This can take place after just one or two drinks.
Drinking a great deal of alcohol rapidly can trigger a blackout– not being able to recall entire happenings, such as what she or he did last night.
If alcohol damages the hippocampus, a person may find it tough to learn and to hold on to knowledge.
CEREBELLUM– The cerebellum is essential for coordination, thoughts, and awareness. A person might have trouble with these abilities when alcohol gets in the cerebellum. After consuming alcohol, a person’s hands might be so unsteady that they can’t touch or take hold of things properly, and they might fail to keep their balance and fall.
HYPOTHALAMUS– The hypothalamus is a small part of the brain that does a fantastic variety of the physical body’s housekeeping tasks. Alcohol frustrates the work of the hypothalamus. After an individual consumes alcohol, blood pressure, hunger, being thirsty, and the need to urinate increase while body temperature and heart rate decrease.
MEDULLA– The medulla manages the physical body’s unconscious actions, such as an individual’s heartbeat. It likewise keeps the physical body at the ideal temperature. Alcohol really cools down the body. Consuming a great deal of alcohol outdoors in cold weather can trigger an individual’s physical body temperature to drop below normal. This hazardous situation is termed hypothermia.
A person might have trouble with these abilities when alcohol goes into the cerebellum. After drinking alcohol, an individual’s hands might be so shaky that they cannot touch or take hold of things normally, and they may lose their balance and tumble.
After an individual alcoholic beverages alcohol, blood pressure, hunger, being thirsty, and the urge to urinate increase while physical body temperature and heart rate decrease.
Alcohol in fact cools down the physical body. Consuming a lot of alcohol outdoors in cold weather conditions can cause an individual’s body temperature level to fall below normal.
