Effects of Alcohol on the Nervous System

As we already said, alcohol is a central nervous system depressant and it acts at many sites, including the reticular formation, spinal cord, cerebellum and cerebral cortex, and on many neurotransmitter systems. Because of its lipo-solubility properties, alcohol gets into the bloodstream very easily and also crosses the blood brain barrier. Some of the neurochemical effects of alcohol are:

• Increased turnover of norepinephrine and dopamine, important neurotransmitters in the brain
• Decreased transmission in acetylcholine systems
• Increased transmission in GABA systems
• Increased production of beta-endorphin in the hypothalamus

 Chronic alcohol use can:

• Damage the frontal lobes of the brain
• Cause an overall reduction in brain size and increase in the size of the ventricles
• Lead to alcoholism and result in tolerance to the effects of alcohol and variety of health problems
• Cause a vitamin deficiency. Because the digestion system of alcoholics is unable to absorb vitamin B-1, a syndrome known as "Wernicke's Encephalopathy" may develop.
• Further deficiencies of thiamine can lead to "Korsakoff's Syndrome." This disorder is characterized by amnesia, apathy and disorientation.

Alcoholism

It could be very difficult to describe the real meaning of the word alcoholism. Some adults seem to be able to enjoy alcohol occasionally with no problems while others become alcoholics. An alcoholic is someone whose mind and body crave alcohol, who has little control over his or her drinking and can't stop drinking without help. It is proven that a person who starts drinking alcohol at a young age is more likely to become an alcoholic. It often gets worse with years because the person may start experiencing health problems related to drinking.

Teen drinking problem

Teen drinking also became very common . Alcohol is by far, the most abused drug among teenagers. Because the body changes as we grow, the ability to cope with alcohol also changes all the time.

Everyone seems to know of someone who can drink booze by the bucket-load but this shouldn't be seen as something to aspire towards. Teens are the most likely group to have their stomachs pumped after excessive alcohol intake. We have to keep in mind that, after all, alcohol is a toxin.

Using alcohol can be a way for teens to try to show maturity and independence.

• the death of a parent or sibling
