title: Neuroleptic-induced tics in two hyperactive children.
abstract: Two hyperactive boys who had developed motor and phonic tics during stimulant treatment reacted similarly to low doses of haloperidol and thioridazine. Neuroleptic-induced tics may be a consequence of presynaptic dopamine blockade.
