George writes: >>The family's understanding has been that the onset of dementia is slow in Parkinson's and that it is expected after many years of illness. Is it possible that the dementia that sometimes accompanies PD could come so quickly and so overwhelmingly? Or should we be looking for other explanations? Any experiences or pointers to relevant information<< The neurologist is "right on". Rapid dementia may well be due to something else, such as a vascular problem, a subdural hematoma (blood clot on the brain), etc. It could also be medicine-related. Follow the lead of that neurologist. Best, Bob -- ******************************************************** Robert A. Fink, M. D., F.A.C.S.
