How it affects the brain : How it affects the brain Damage the frontal lobes of the brain Cause an overall reduction in brain size and increase in the size of the ventricles alcohol contracts brain tissue and depresses the central nervous system. Also, alcohol destroys brain cells and unlike many other types of cells in the body amnesia, apathy and disorientation Lead to alcoholism Tidbits : Tidbits Youth who drink can have a significant reduction in learning and memory, and teen alcohol users are most susceptible to damaging two key brain areas that are undergoing dramatic changes in adolescence: The hippocampus handles many types of memory and learning and suffers from the worst alcohol-related brain damage in teens. Those who had been drinking more and for longer had significantly smaller hippocampi (10 percent). The prefrontal area (behind the forehead) undergoes the most change during adolescence. Researchers found that adolescent drinking could cause severe changes in this area and others, which play an important role in forming adult personality and behavior and is often called the CEO of the brain. Drugs are Bad : Drugs are Bad Drugs are Chemicals they work in the brain by tapping into its communication system and interfering with the way nerve cells normally send, receive, and process information Some drugs can make you look older causing wrinkly skin and lose of hair The most common drugs and their effects : The most common drugs and their effects Marijuana- The parts of the brain that control emotions, memory, and judgment are affected by marijuana. It also weakens short term and long term memory. Cocaine- Cocaine is an extremely addictive stimulant that makes you lose interest in many areas of life, including school, sports, family, and friends. Use of cocaine can lead to feelings of paranoia and anxiety. Although often used to enhance sex drive, physical effect of cocaine on the receptors in the brain reduce the ability to feel pleasure. Ecstasy- destroys certain cells in the brain. While the cells may re-connect after discontinued use of the drug, they don't re-connect normally. Like most drugs, this one impairs memory and can cause paranoia, anxiety, and confusion. DRUGS that effect the brain : DRUGS that effect the brain Inhalants : Inhalants Inhalants can be sniffed. It effects the brain almost immediately. And while some vapors leave the body quickly, others will remain for a long time. The tissues protecting the nerve cells in the brain are destroyed by the inhalant vapors. This slows down or even stops neural transmissions in the brain. Some inhalants are: glue gasoline hair spray paint thinner Conclusion : Conclusion In conclusion, alcohol and drug are depressants that change peoples mood. Drugs and alcohol and ruin your life. If you take to much of them you can die.
