title: Smoking-responsive juvenile-onset Parkinsonism.
abstract: We describe a patient with juvenile levodopa-responsive Parkinsonism who reported a dramatic response to cigarette smoking with transient but marked improvement of motor symptoms associated with oculogyric crises and psychotic behavior. His beta-CIT single-photon emission computed tomography scan showed a complete absence of presynaptic dopaminergic nerve terminals.
