The efficacy of low doses vs standard or high doses of traditional neuroleptics in this group of patients has not been extensively investigated and thus represents an important gap in the low-dose research and treatment strategy. This letter reports an attempt to address this important clinical question.

Patients and Methods.  In the course of clinical management of a service of chronically psychotic female patients, a program of neuroleptic dosage reduction combined with quantitative monitoring of their psychopathologic condition was
