Friends, maybe someone can tell us if they have had similar symptoms to a couple which really are bugging Peter of late: Spasms of tongue biting--different from the unconscious chewing of the tongue that he has had for months, these are sharp, sudden bites that hurt, and even wake him up at night when it happens in his sleep. It seems somewhat comparable to a jerk or dyskinesia. The sideways,rhythmic jaw movement which he developed when there was a slight increase in Sinemet, seems to have disappeared when I cut back to the lower dose. (The increase was only from 20/200 (2-10/100s) to 25/250 in 3 hrs,but that may have put him,finally, overthe edge to dyskinesia. The other symptom is different from a regular PD tremor--which he has almost none of--and is a violent trembling or shaking hard to control, which occurs when he first rises from a seat, and gets worse if someone grabs and tries to help/hold him. It's a "wild bouncing up and down" which makes him panicky, and even more so if anyone tries to hold onto him. It's scary to watch, as it seems he will fall over--but it soon stops if he can get control of it himself, stabilize with a walker, etc. So far, he hasn't fallen, however. I have posted about our experience with Aricept, which unfortunately didn't help him, and apparently added insomnia,nausea, and anorexia to his symptom life,till we stopped it. Has anyone else had this experience with this med, whichso many have found helpful? He's now eating again a bit better and I hope will regain at least some of the 20 lbs he lost! Any suggestions, comments, will be of interest--we see his neuro on Monday, and will ask for a Mirapex RX .
