Alcohol Can Cause Modifications In The Operation Of The Growing BrainAlcohol consumption can cause changes in the structure and function of the growing brain, which continues to mature into an individual's mid 20s, and it may have consequences reaching far beyond teenage years.
In adolescence, brain development is characterized by remarkable changes to the brain's architecture, neuron connectivity ("electrical wiring"), and physiology. These transformations in the brain affect everything from emerging sexuality to emotions and judgment.
Not all parts of the juvenile brain mature at the exact same time, which may put a juvenile at a disadvantage in particular situations. The limbic areas of the brain mature earlier than the frontal lobes.
Ways Alcohol Alters the Brain Alcohol affects an adolescent's brain growth in several ways. The consequences of adolescent drinking on specific brain functions are detailed below. alcohol is a central nervous system sedative drug. Alcohol can appear to be a stimulant because, to begin with, it depresses the part of the brain that manages inhibitions.
CORTEX-- Alcohol hinders the cortex as it processes information from a person's senses.
CENTRAL NERVOUS SYSTEM-- When a person thinks about something he desires his body to undertake, the central nervous system-- the brain and the spine-- sends a signal to that part of the body. Alcohol reduces the central nervous system, making the person think, converse, and move more slowly.
FRONTAL LOBES -- The brain's frontal lobes are necessary for planning, forming concepts, decision making, and using self-control.
An individual might find it difficult to manage his or her feelings and urges once alcohol impacts the frontal lobes of the brain. The individual may act without thinking or may even get violent. drinking alcohol over a long period of time can harm the frontal lobes forever.
HIPPOCAMPUS-- The hippocampus is the part of the brain in which memories are made. Once alcohol gets to the hippocampus, a person may have difficulty recalling something she or he just learned, such as a person's name or a phone number. This can occur after just one or two alcoholic beverages. Drinking a great deal of alcohol rapidly can trigger a blackout-- not being able to recollect whole happenings, such as what exactly he or she did the night before. If alcohol damages the hippocampus, a person may find it difficult to learn and to hold on to information.
CEREBELLUM-- The cerebellum is important for coordination, thoughts, and attention. When alcohol gets in the cerebellum, an individual may have trouble with these abilities. After drinking alcohol, a person's hands may be so tremulous that they cannot touch or take hold of things properly, and they may fail to keep 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 upsets the operation of the hypothalamus. After a person consumes alcohol, blood pressure, hunger, thirst, and the impulse to urinate increase while 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 trigger an individual's body temperature level to fall below normal.
A person may have difficulty with these skills when alcohol gets in the cerebellum. After consuming alcohol, an individual's hands may be so unsteady that they cannot touch or get hold of things properly, and they might lose their balance and fall.
After a person alcoholic beverages alcohol, blood pressure, appetite, thirst, and the urge to urinate increase while body temperature and heart rate decrease.
Alcohol actually cools down the physical body. Consuming a lot of alcohol outdoors in cold weather conditions can cause an individual's physical body temperature level to fall below normal.
