Brief Summary
Electroconvulsive Therapy (ECT) remains essential to contemporary psychiatric practice and is one of the safest and most effective treatments available for depression. Despite modern advances in pharmacotherapy, about 15-20 per cent of all hospitalised patients receive treatment with ECT. Its use, however, is limited by concerns over associated cognitive side effects. Recent research has suggested that using an ultrabrief pulsewidth with ECT may greatly reduce cognitive side effects, while maintaining efficacy (Sackeim et al 2008). Preliminary results were positive for unilateral ECT, however, suggest that for bilateral ECT, dosing may need to be adjusted to preserve efficacy while reducing side effects. This study will examine the relative cognitive side effects and efficacy of right unilateral and bilateral ECT given with a standard pulsewidth or an ultrabrief pulsewidth. Some participants will also receive an MRI scan before and after ECT.

Study Arms (4)
bilateral-ultrabrief ECT
EXPERIMENTALPatients will be treated with an ultrabrief (0.3ms) pulse with a bilateral placement at 3-4 times seizure threshold.
bilateral standard ECT
ACTIVE COMPARATORPatients will be treated with a standard (1.0ms) pulse with a bilateral placement at 1.5 times seizure threshold.
right-unilateral ultrabrief ECT
EXPERIMENTALPatients will be treated with an ultrabrief (0.3ms) pulse with a right unilateral placement at 8 times seizure threshold.
right-unilateral standard ECT
ACTIVE COMPARATORPatients will be treated with a standard (1.0ms) pulse with a right unilateral placement at 5 times seizure threshold.
Interventions
Bilateral ECT at 3-4 times seizure threshold with an ultrabrief pulse (0.3ms)
Bilateral ECT with at 1.5 times seizure threshold with a standard pulse (1.0ms)
Right-unilateral ECT at 6 times seizure threshold with an ultrabrief pulse (0.3ms)
Right-unilateral ECT with at 5 times seizure threshold with a standard pulse (1.0ms)
