Electroconvulsive therapy (ECT) for the management of neuroleptic malignant syndrome (NMS) in adults

To determine the efficacy and safety of electroconvulsive therapy (ECT) for the management of neuroleptic malignant syndrome (NMS) in adults. Study Design: Open label, unblinded series. Place and Duration of Study: This study was carried out at the Department of Neurology, Military Hospital Rawalpindi, from Jan 2015 to Dec 2015. Material and Methods: All the patients with the diagnosis of NMS during the study period were included in the study. Consective non-probability sampling technique was used. Patients were divided into two groups; uncomplicated and complicated cases of NMS. Results: A total of nineteen patients were included in this pilot study. Out of all, thirteen (68.4%) were males and six (31.6%) were females. Mean age of the patients was 35.05 (SD 13.362) years. The drug classes causing NMS were antipsychotic medicines in 73.7% of patients and antiemetics in 26.3% of patients. Mean electroconvulsive therapy (ECT) sessions given were 6.16 (SD 2.062). Following treatment n=16 (84.2%) patients had complete recovery while n=3 (15.3%) patients died. Conclusion: In this small, open label, unblinded study ECT appears effective and safe in treating NMS in adults. Larger randomized studies will help to confirm data emerging from this preliminary study. (author)
