ECT administration to a hyperthyroid patient.

There are few reported convincing cases of hyperthyroid depressed patients receiving electroconvulsive therapy (ECT). We describe a depressed 66-year-old woman with catatonic depression diagnosed with new-onset hyperthyroidism due to Grave's disease. After commencing propylthiouracil, her Grave's disease was partially treated, but her depression was no better. She subsequently received a course of seven ECT with resolution of her depression and no adverse sequelae.
