Redirecting my research

I'm now researching specifically on treatment for Parkinsons which includes various research projects that are working on new potential and more effective treatments, for example stem cell therapy has shown to eliminate some of the symptoms in testing animals such as rats with Parkinson's. This indicates a possible treatment method for Parkinsons patients, but further research will need to be done on this treatment including human trials before it can be used. As a result this treatment will be expensive but still better than taking a 'cocktail' of drugs that also have their own side effects.
