Frequency and presentation of neuroleptic malignant syndrome: a prospective study
PE Keck Jr, HG Pope Jr and SL McElroy
Epidemiology Laboratory, McLean Hospital, Belmont, MA 02178.
In an 18-month prospective assessment of 679 hospitalized, neuroleptic-
treated patients, the authors, using previously defined operational
criteria, diagnosed neuroleptic malignant syndrome in six cases (0.9%).
This supports their earlier finding that the syndrome appeared in about 1%
of neuroleptic-treated patients.
