title: Severe stuttering and motor tics responsive to cocaine.
abstract: Developmental stuttering and tics share many clinical and therapeutical aspects. Dopaminergic neurotransmission seems to be involved in the pathophysiology of both, tics and stuttering. We report on a patient with severe stuttering and mild facial tics which were dramatically improved by cocaine, challenging previous reports.
