Movement disorder specialty is a relatively new branch of neurology. The training program in this subspecialty was started by Dr. Stanley Fahn who is at NYU med center at present, a neurologist in Tx and one in France (whose names I do not recall). Cerebrovascular diseases' major area of interest is strokes or "cerebrovascular accidents" and vascular abnormalities. I cannot imagine why parkinson's would be placed under that umbrella.......esp since only vascular PD may apply; idiopathic PD is not thought to be vascular in origin, which makes up the largest % of patients diagnosed with PD. Vicky, where did you receive your information? the reproduced article did not place PD under cerebrovascular diseases. thanks, madelyn
