United Parkinson Foundation 833 W. Washington Boulevard Chicago, IL, USA 60607 312-733-1893 Just received a VERY informative pamphlet on PD from the above. Here's a direct quote from Page 1. Q. "Is Parkinson's disease hereditary?" A. "NO. Although there are OCCASIONAL reports of families where parkinsonism has occurred over several generations, such instances are considered RARE. If the patient finds that other relatives suffer with shaking or have difficulty walking, it is MUCH more likely that the patient's family has FAMILIAL TREMOR, which is NOT Parkinson's disease. The two diagnoses can be separated in that the tremor of parkinsonism is seen at rest, and that of familial tremor is more promineent when the patient moves, as in writing or eating. The two conditions are not mutually exclusive, and a patient with familial tremor in his ancestry may, of course, have parkinsonism, or may have both simultaneously." The UPF people in Chicago are VERY nice to talk to over the phone and can be very helpful. Besides the PD pamphlet, they sent me another one on Essential Tremor, which I take to be approximately the same as Familial Tremor. They also steered me and my wife to a nearby "movement disorder clinic" where the doctors are more experienced with PD and ET than most FPs, or even neurologists. Good people! The pamphlet on Essential Tremor was put out by: International Tremor Foundation 833 W. Washington Boulevard Chicago, IL, USA 60607 312-733-1893 Notice that they share offices with United Parkinson Foundation. However, I don't know anything about them as yet, except that their ET pamphlet was informative. Paul Millikin [log in to unmask]
