Re: sweating and shivering: My husband, John, 63, who has progressive supranuclear palsy (PSP) has had episodes that could be described as sweating and shivering. They evolved in some cases to severe "shivering"...actual myoclonus, as his neuro put it, or severe spasms of his trunk and extremities, as I would put it. But it really was like an extreme case of shivering like we do up here in New England when we are freezing and just can't get warm! Anyway, he was hospitalized for one episode - 48 hours - and the assessment was that he had an autonomic nervous system "storm" triggered by diminished fluid intake which in turn resulted in low urinary output...the neurologic nature of PD and PSP contributes to bladder issues which in turn can trigger these autonomic storms. The take-home message is, fluids! There must be a minimum of 1500 (says our neuro) - 2000 (says the urologist) cc. of water/juice per day. Coffee/tea do not count. Must be water, herbal tea or juice. We have had subsequent episodes of this...some not so severe. Now I can see it coming when his fluid intake falls off and we simply try to be vigilant. The problem is that he has a lot of coughing/throat-clearing issues when he drinks water so he doesn't like to drink it. Anyway, that's our experience. Hope it is helpful. ***** Janice Clements 649 Everest Rd. Milton, VT 05468 (802) 893-1263
