RESUMEN

OBJECTIVE: The Montreal Cognitive Assessment (MoCA) is a commonly used brief cognitive screening tool for monitoring adverse cognitive effects of electroconvulsive therapy (ECT). The aim of this study was to examine three statistical methods for detecting reliable change in the MoCA following ECT. METHODS: In a prospective cohort study, 47 patients (mean age 55.2 [SD = 12.8], 59.6% female) with unipolar or bipolar depression treated with an acute course of brief-pulse ECT (72.3% right unilateral) and 47 depressed controls without ECT exposure were tested on the MoCA at baseline and retested at comparable time intervals. ECT patients' performance was also compared to published normative data from a community-based sample of older adults. We calculated proportions of ECT patients remaining stable, declining, and improving following ECT using practice-corrected reliable change index, standardized regression-based formulas, and minimum detectable change cutoff of ±4 MoCA points. RESULTS: Using the three methods, 72.3%-78.7% of ECT patients remained stable, 17.0%-23.4% declined, and 4.3% improved in MoCA performance following ECT compared to the two control groups. CONCLUSIONS: All three methods yield consistent estimates of reliable change in MoCA scores from pre- to post-brief-pulse ECT. The minimum detectable change approach may be the most efficient and accessible method of detecting change due to simplicity of calculation.

RESUMEN

OBJECTIVE: Electroconvulsive therapy (ECT) is an effective treatment for major depressive disorder, but some aspects remain controversial. Few studies have taken an in-depth mixed methods approach toward the study of attitudes, and there are no significant studies that explore the change of attitudes before and after treatment. The aim was to compare attitudes of patients and their relatives before and after ECT using quantitative and qualitative methods. METHODS: One hundred twenty-three participants were recruited. Forty-one patient/relative participants were recruited from 2 accredited ECT centers along with 82 age- and sex-matched general population controls. A validated 22-item survey about attitudes toward ECT was administered. Patient/relative participants completed the survey before treatment with ECT and engaged in a repeat survey and a semistructured interview 1 month after completion of ECT. Control participants completed the survey on a single occasion. RESULTS: Control versus pre-ECT surveys and pre-ECT versus post-ECT surveys both demonstrated statistically and clinically significant positive attitudinal differences (Cohen d = 1.37, P < 0.001; Cohen d = 1.2, P < 0.001). These differences were maintained for both the patient and relative pre/post subgroups (Cohen d = 1.15, P < 0.001; Cohen d = 1.33, P < 0.001). Qualitative analysis identified 13 attitudinal transitions in cognition, emotion, and imagery domains. CONCLUSIONS: This is the first study to examine a change in attitudes toward ECT of patients, their relatives, and with controls using mixed methods. The findings suggest a 2-phase positive attitudinal change, in which accurate information (phase 1) and experiential learning (phase 2) are both key components. These findings address stigma through accurate knowledge and experiential learning, with a positive outcome through changed attitudes.

RESUMEN

Mitochondrial dysfunction may play a role in various psychiatric conditions. Mitochondrial DNA copy number (mtDNAcn), the ratio of mitochondrial DNA to nuclear DNA, represents an attractive marker of mitochondrial health that is easily measured from stored DNA samples, and has been shown to be altered in depression. In this study, we measured mtDNAcn in whole blood samples from medicated patients with depression (n = 100) compared to healthy controls (n = 89) and determined the relationship between mtDNAcn and depression severity and the therapeutic response to electroconvulsive therapy (ECT). We also explored the relationship between mtDNAcn and telomere length and inflammatory markers. Our results show that mtDNAcn was significantly elevated in blood from patients with depression when compared to control samples, and this result survived statistical adjustment for potential confounders (p = 0.002). mtDNAcn was significantly elevated in blood from subgroups of patients with non-psychotic or unipolar depression. There was no difference in mtDNAcn noted in subgroups of ECT remitters/non-remitters or responders/non-responders. Moreover, mtDNAcn was not associated with depression severity, telomere length, or circulating inflammatory marker concentrations. Overall, our results show that mtDNAcn is elevated in blood from patients with depression, though whether this translates to mitochondrial function is unknown. Further work is required to clarify the contribution of mitochondria and mtDNA to the pathophysiology of depression and the therapeutic response to antidepressant treatments.
