I too find dyskinesia a bit of a puzzle. I started on Sinemet 5 minutes after I was diagnosed and it (dysk) never turned up for 5-7 years. Even now it turns up unpredictably. Food seems to be the best management option for getting it under control, and sugar (glucose laden foods) will set it off in my case. One Neuro told me that the definition of dyskinesia is any dyfunction related to our Kinesiology. Thats an awfully broad definition. I look forward to reading your experiences with this bothersome side effect. Has anyone heard of any experiments where they induced dyskinesia in monkeys? Some how a dyskinetic fruit fly doesn't strike me as very helpful in terms of studying this odd side effect.
