Neuroleptic malignant syndrome: case report A 28-year-old man developed neuroleptic malignant syndrome following treatment with thioridazine and valproate [therapeutic indications not clearly stated]. The man, who had a history of bipolar mood disorder and mental retardation, was hospitalised with muscle rigidity, impaired consciousness, elevated body temperature, cognitive impairment and diaphoresis [time to reaction onset not stated]. He was receiving thioridazine and valproate, which had been administered for 6 months [routes and dosages not stated]. He exhibited postures characteristic of catatonia and was mute. Tests revealed the following values: temperature 38.2°C, creatine kinase 1245 U/L, BP 131/82mm Hg, HR 114 beats/min and respiratory rate 18; other laboratory results including electrolytes were also raised. He was living in a mental disorder institute following several previous psychiatric admissions. Antipsychotic drugs were withdrawn; the man was diagnosed with neuroleptic malignant syndrome. He developed worsening muscle rigidity and catatonia, and electroconvulsive therapy was performed under anaesthesia. After a few weeks of treatment, decreasing creatine kinase levels were noted with improved psychotic symptoms; he returned home with no additional complications.
