Abstract
Retrograde amnesia for autobiographical memories is a commonly self-reported cognitive side effect of electroconvulsive therapy (ECT) but it is unclear to what extent objective performance differs between ECT-exposed and unexposed patients with depression. We investigated the association between exposure to brief-pulse (1.0 ms) bitemporal or high-dose right unilateral ECT and retrograde amnesia at short- and long-term follow-up compared to inpatient controls with moderate-to-severe depression without lifetime exposure to ECT receiving psychotropic pharmacotherapy and other aspects of routine inpatient care. In propensity score analyses, statistically significant reductions in autobiographical memory recall consistency were found in bitemporal and high-dose right unilateral ECT within days of an ECT course and three months following final ECT session. The reduction in autobiographical memory consistency was substantially more pronounced in bitemporal ECT. Retrograde amnesia for items recalled before ECT occurs with commonly utilised ECT techniques and may be a persisting adverse cognitive effect of ECT
