- OBJECTIVES: This study aimed to compare the long-term effects of maintenance electroconvulsive therapy (M-ECT) with medication and medication only in patients with depression.METHODS: A randomized controlled trial of 1 year of M-ECT with medication or medication only investigated relapse/recurrence among 56 patients in remission after electroconvulsive therapy (ECT) for depression was conducted. The results of the first year are published already and showed a significant advantage of M-ECT with medication.The current study was a long-term follow-up. When the randomized treatment allocation ended, medication was continued in both groups but M-ECT was terminated. Patients were followed for up to 10 years via Swedish national registers until the study endpoint of a new psychiatric diagnosis as an inpatient, suicide, suspected suicide, or death of another cause. Time to relapse was compared between the M-ECT with medication group and the medication-only group using Kaplan-Meier estimates.RESULTS: The median follow-up time was 6.5 years for the M-ECT and medication group and 3.1 years for the medication-only group. One year after randomization 22 patients remained in the M-ECT and medication group, and 14 patients remained in the medication-only group. Relapse patterns between the treatment groups after the completion of M-ECT seemed to be similar according to visual inspection.CONCLUSIONS: This long-term follow-up study suggests that most of the benefit achieved during the treatment period with M-ECT is maintained over several years, but the small sample size, with accompanying large statistical imprecision, makes the results uncertain. More long-term studies of M-ECT are required.Trial registration: ClinicalTrials.gov identifier: NCT00627887.

- Objectives: The aims of the present study were to describe the short-term rate of subjective memory worsening (SMW) and identify factors of importance for SMW in a large clinical sample treated for depression with electroconvulsive therapy (ECT).Methods: This register-based study included 1212 patients from the Swedish National Quality Register for ECT. Subjective memory worsening was defined as a 2-point worsening on the memory item of the Comprehensive Psychopathological Rating Scale from before to within 1 week after treatment. Associations between patient characteristics and treatment factors were examined using logistic regression.Results: Subjective memory worsening was experienced in 26%. It was more common in women than in men (31% vs 18%; P < 0.001) and more common in patients aged 18 to 39 years than in patients 65 years or older (32% vs 22%; P = 0.008). Patients with less subjective memory disturbances before ECT had a greater risk of SMW. Patients in remission after ECT had a lower risk of SMW. A brief pulse width stimulus gave higher risk of SMW compared with ultrabrief pulse (odds ratio, 1.61; 95% confidence interval, 1.05-2.47).Conclusions: Subjective memory worsening is reported by a minority of patients. However, young women are at risk of experiencing SMW. Ultrabrief pulse width stimulus could be considered for patients treated with unilateral electrode placement who experience SMW. Each patient should be monitored with regard to symptoms and adverse effects, and treatment should be adjusted on an individual basis to maximize the clinical effect and with efforts to minimize the cognitive adverse effects.
