Earlier this month, a curious report caught my attention. Apparently there exists no rigorously established evidence that electric shock therapy, or ECT (electroconvulsive therapy), works. At all. In Electroconvulsive Therapy for Depression: A Review of the Quality of ECT versus Sham ECT Trials and Meta-Analyses, Dr John Read, Professor Irving Kirsch and Dr Laura McGrath have shown that the therapy, commonly administered for severe depression, has not (despite claims) been shown to have any significant positive effect, ever.
