mirror movement disorder

Hi everyone. I have always had problems with my left hand mimicking my right hand. I always thought it must be a symptom of my hydrochephalus and didn't think anymore about it. For some reason I decided to research it and found out that it was something called mirror movement disorder and was actually quite rare! Mine isn't too bad which is probably why I hadn't bothered researching it before. I causes me more embarrassment than anything else! When I was at school I used to try and hide it as best I could. It means that my co-ordination isn't very good. I have seen videos on youtube where it has completely taken over peoples lives!
