Rolandic epilepsy with paroxysmal exercise-induced dystonia and writer's cramp (EPRPDC) is an autosomal recessive neurologic disorder characterized by onset of focal seizures in infancy and exercise-induced dystonia in childhood. Features usually include involuntary movements, including facial movements, and difficulties with fine motor skills of the hand. Seizures often respond to medication and remit with age; the dystonia tends to persist (summary by Luthy et al., 2019).
