Dear Friends, I have been largely a "lurker", but would like your input on the subject of dystonia (or is it dyskinesia) and PD. Would anyone who can say please let me know if they ever experienced any episodes of dystonia or freezing prior to going on sinemet? My husband was diagnosed in late Jan. or early Feb. and recently experienced an episode where the muscles of his hand, arm, chest, leg and foot (all on the left) contracted and would not release for over a minute. There was significant tremor involved. He was at his desk when this occurred and was able to hobble to the door of his office to try to get the attention of his secretary who, as it turned out, had stepped into another office. At that point, he felt that he might "gray out," as he put it so decided to lie down on the floor until he regained function, which he wasn't sure was going to happen. It did and he was left only with residual soreness in the muscles involved. His neurologist at Ford Hospital in Detroit was out of town but the doctor who was covering for him suggested that Art come in for tests. He spent the night and all of the next day having thorough workup--including all sorts of blood work, physical exams, an MRI, and an EEG. Their conclusion was dystonia and he has been placed on Sinemet, though he is not yet up to a therapeutic dose, so has not been able to see any appreciable results in the short time (now 4 days) that he has been on it (25/100 two times daily and next week 25/100 three times daily). Naturally, he's terrified that this may happen again and is not convinced that it was not vascular though he's been assured that it isn't. Would appreciate your input.
