Neurol India. 2007 Apr-Jun;55(2):166-8. doi: 10.4103/0028-3886.32793.

Abstract

Neuroleptic malignant syndrome (NMS) is a rare, life-threatening but potentially treatable condition. This study was performed to investigate the clinical spectrum, antecedent events and outcome of NMS patients admitted in the Neurology department of a large teaching hospital of North India. Fourteen cases of NMS were taken after a thorough search during a three-year period (May 2000 to April 2003). The Incidence of NMS was 1.40/ 1000 patients treated with neuroleptics and mortality rate was 14.28%. Amongst the neuroleptics Haloperidol (parenteral) was implicated as a most common drug for NMS in 57% of patients. An association with coexisting precipitating illness was clearly recorded in 71.4% patients. All the recorded patients of NMS received 500-700 mg CPZ equivalent/day of neuroleptics. NMS as an indiosyncratic phenomenon was noticed in 28% patients. 85.7% responded to dopaminergic drugs along with supportive treatment and showed partial or complete recovery within 7-14 days. In those with partial recovery residual deficits included Parkinsonian features, depression and diaphoresis in a small percentage of patients.
