‐ The literature concerning acute changes in memory functions following electroconvulsive therapy (ECT) is reviewed. Most studies indicate that low‐energy brief‐pulse ECT is followed by less amnesia than high‐energy sinusoidal ECT. Many studies show that amnestic deficits are exacerbated with increasing treatment number. However, it is unclear whether this exacerbation is related to increased electrical energy typically used to induce threshold seizures in the latter treatments Or to more endogenous physiological alterations of the CNS across treatment number. Practical and theoretical implications of these issues are discussed.
