The "neuroleptic" antipsychotic drugs. 2. Neurologic side effects.

The specific neurologic side effects of the antipsychotic agents include acute dystonias, parkinsonism, motor restlessness, and late choretoathetosis. Treatment of the acute reactions is usually effected by the use of anticholinergic agents; treatment of the later dyskinesias is unsatisfactory, and these reactions are to be avoided by judicious use of antipsychotic drugs for long-term treatment.
