Athetosis - I just noticed that the definition given is flawed. The abnormal movements are not
"twitching" - they are slow and writhing. And the dictionary definition errs in calling it a muscular
disorder. The lesion is in the central nervous system, and not limited to "cerebtral palsy" , though
that would be the most common cause.
