Abstract
Rapid onset dystonia parkinsonism (RDP) is a rare autosomal dominant movement disorder characterized by sudden onset of dystonia with bradykinesia predominant parkinsonism, which often plateaus, prominent cranial involvement which progresses caudally to involve arm and leg, and minimal response to dopaminergic therapies. Mutations in the Na+/K+-ATPase α3 subunit (ATP1A3) have been discovered in familiar cases, implicating a dysfunction of this pump as the etiology of RDP.
