Electroconvulsive therapy in a patient with multiple sclerosis and recurrent catatonia.

Catatonia is a rare complication of multiple sclerosis (MS). We present a case of a 28-year-old inpatient with MS successfully treated with electroconvulsive therapy (ECT) after developing a catatonic syndrome. A subsequent relapse also responded to ECT, after which the patient received maintenance ECT for 13 months without complications. Follow-up 18 months later did not reveal any evidence of neurological deterioration. We conclude that ECT was a safe and effective treatment in this MS patient.
