Hi.. Parkinsonism is a chronic condition.. The treatment that are available presently are only preventive and not complete cure.. Recent studies of stem cell therepy are in progress for finding a probably cure.. Lets hope this study succeeds in finding us the cure of parkinsonism and many more chronic disease... Untill then, you may have to wait.. Or you can become part of this study, since there are no severe ill effects of this procedure and hope this therapy succeeds...
