Young onset P.D. is becoming more and more prevalent within the U.S. and is definitely an issue that should not be ignored. Other than working on finding a cure for this disease (don't get me wrong, this is VERY important) researchers must start looking at preventive care. The first step to finding a cure is knowing the cause. Researchers need to start looking at the environment. I am a biology major and let me tell you for sure, there isn't a gene, allele, chromosome, whatever that is stamped P.D. Its the combination of traits and how they are paired that make a person more susceptible to Parkinson's. I hypothesize that its something in the environment or maybe even a disease that makes someone more susceptible to this particular disease. I have inactive TB and only active TB is a problem. Pneumonia can activate TB by suppressing the immune system...this is exactly how P.D. works. A chemical in the environment (chrome, chlorine, nickel in the water supply for example) kills the group of cells in the thalamus that produce dopamine. There are only two wayts to explain why your brain isnt producing dopamine. (1)Your brain stops producing Dopamine because for some reason your body doesn't need it anymore, its not because it can no longer produce this vital chemical (2)Your brain forgets how to produce it. The cure for P.D. is a combination of preventive care and finding a way to trick our brain, the most powerful and most respectable organ in our body.
