title: Dopa responsive dystonia with diurnal fluctuation (Segawa's syndrome).
abstract: A 10-year-old girl presented with progressive dystonia with diurnal fluctuation. Response to low dose L-Dopa was dramatic and sustained with no complications. Recurrence of symptoms was observed on attempted withdrawal. Because of the dramatic response to therapy, dopa-responsive dystonia must be considered in the differential diagnosis of disorders presenting as gait disorders in childhood.
