The research for treating Parkinson's disease is a very risky area. Although Parkinson's is life threatening, no one should go to the lengths of fetal brain cell implantations to change inevidability.

Lack of dopamine (a chemical found in the brain) is the cause of Parkinson's disease. By transplanting "human embryotic brain cells" the balance of dopamine which is controlled by the brain, is able to continue because of the increased production. However, if the transplanted brain cells "over produce" dopamine, "nasty side effects will begin. The side effects that are observed from over production are the makings of Skitzofrenia.

When experimental study began for grafted cell transplants, the scientists encountered several side effects in their patients. After a period of observation, regarding the transplant "15% of the patients also developed uncontrollable movements." Although a scientist from the University of Colorado stated that "there were problems with the study desgin," there should still be no room for human error should be surpased in such critical areas.

Parkinson's may be a disease, however it is also a course of life for some. The lives of these people should not be balanced in the hand of luck for a chance to improve their conditions. Human error is inevidable, why should anyone have to rely on that?
