Abstract

IN THE course of pharmacologic therapy of a patient who exhibited Parkinsonian phenomena associated with forced crying and laughing, it was observed, as a result of medication, that, together with the diminution in tremor amplitude, there was a definite decrease in the frequency and intensity of the paroxysmal episodes of crying and laughing.
