What is an adequate treatment in convulsive therapy?

The parameters of the induction of an effective electroconvulsive therapy (ECT) treatment are poorly defined. We find variations in outcome, with changes in electrode placement and energy levels, despite measures of motor seizure duration greater than 25 s. To maximize the outcome of ECT, attention is again focused on the electrophysiologic and biochemical features of seizures, much as Ottosson studied them in 1960.
