Hi-- I'm new to this service. I'm writing on behalf of my 80-year-old father-in-law, who's had Parksinson's for a few years. During the last 2 years or so, he's had a problem with orthostatic hypotension. In other words, sometimes, when he stands up, his blood pressure drops extremely low. He's passed out a few times, and had to be taken to the emergency room a few times. He's on Sinemet, Eldeprel, proamatine, and florinef acetate. I've looked at some 300 messages from people on this list, and no one has mentioned this problem, so I'm assuming it's rare. He's seeing a neurologist, not a PD specialist. Aside from this symptom, he seems to be having some memory loss, his speech is very slow, and his movements stiff. But it's the low blood pressure we're concerned about. I wonder if this could be life threatening? Also, we live in the L.A. area. I don't know if this question is appropriate, but if it is--does anyone know a good PD specialist here? Thanks so much for any information. Jackie Naiditch ([log in to unmask])
