Dear Editor,

Dopa-responsive dystonia (DRD) encompasses a group of clinically and genetically heterogeneous disorders that respond markedly well to l-DOPA [1]. Most cases begin with dystonia in a lower extremity, which progresses to segmental or generalized dystonia [2]. However, DRD is clinically and genetically heterogenous disorders, which often leads to misdiagnosis, which delays treatment. Here, we report a young woman with DRD presenting with subacute-onset hemifacial dystonia.

A 23-year-old woman was admitted to our hospital with a several-month history of right hemifacial dystonia. She had been born by a normal delivery and her development had been normal. There was no family history of movement disorders. Initially, facial dystonia began in the morning and lasted for short periods (several minutes). No diurnal fluctuations were observed. Over several months, the duration of the dystonia lengthened progressively and eventually continued throughout the day. The patient’s...
