Stem cell research is a controversial topic that has become a heated national debate. Researchers have found that embryonic stem cells can divide and regenerate. These embryonic stem cells can grow into many types of cells and tissues. Scientists believe that embryonic stem cells can have a positive impact in finding a cure for a wide range of diseases including Parkinson's disease, while conservative groups have compared the use of embryonic stem cells to abortion. This has prompted the government to limit federal funding for embryonic stem cell research to only a few pre-existing cell lines (Rosenwald). Amid all controversy surrounding stem cells and their research, patients with Parkinson's disease and their families are losing valuable time in their search for a cure.
"Parkinson's disease is a progressive, neurologic disorder caused by a degeneration of dopamine neurons." (Hauser 11). Dopamine is a chemical in the brain that is involved in helping to control motor skills in the human body. When dopamine levels in the brain are reduced by 60 to 80% the symptoms of Parkinson's disease appear (Hauser 11). Every patient will experience symptoms to a varying degree depending on their individual case.
