Rapid-onset dystonia-parkinsonism (RDP) is a rare, movement disorder with variable characteristics ranging from sudden onset (hours to days) of severe dystonic spasms to gradual onset of writer's cramp. RDP has elements of both dystonia and Parkinson's disease—two neurological diseases with motor and neuropsychological symptoms that hinder the quality of life. An internal trigger associated with extreme physiological stress has been reported prior to abrupt symptom onset of RDP.
