DOPA RESPONSIVE DYSTONIA: A CASE REPORT

Dopa responsive dystonia (DRD) is a dystonic syndrome of childhood, usually affecting gait and subsequently developing into parkinsonism with a dramatic therapeutic response to levodopa. At the best of our recollection this is the first case in Iranian medical literature of a 13 year old boy, affected by this interesting, rare and treatable disease which can be easily diagnosed if clinicians have a high index of suspicion. We also have a brief discussion on the pathophysiology of DRD.
