I think its great to have a FAQ Archive---however, I did find one error. According to the Taber's Cyclopedic Medical Dictionary, "Parkinsonism" is indeed Parkinson's Disease--Not some other disease with Parkinson Symptoms, as stated in J. R.Bruman's original Frequently Asked Questions. Also, according to my Neurologist, the term " Parkinsonism" is used to differentiate between "Idiopathic Parkinson's Disease" meaning the cause is unknown and the term "Parkinsonism" is used where the cause is known ---head trauma, certain types of poisonings, etc. Many thanks to you J.R. for getting this started--it has been need for quite sometime!!
