Insight Into

<b><i>Background/Aims/Methods:</i></b> Electroconvulsive therapy (ECT) is still one of the most potent treatments in the acute phase of major depressive disorder (MDD) and particularly applied in patients considered treatment resistant. However, despite the frequent and widespread use of ECT for &#x3e;70 years, the exact neurobiological mechanisms underlying its efficacy remain unclear. The present review aims to describe differential antidepressant and cognitive effects of ECT as well as effects on markers of neural activity and connectivity, neurochemistry, and inflammation that might underlie the treatment response and remission. <b><i>Results:</i></b> Region- specific changes in brain function and volume along with changes in concentrations of neurotransmitters and neuroinflammatory cytokines might serve as potential biomarkers for ECT outcomes. <b><i>Conclusions:</i></b> However, as current data is not consistent, future longitudinal investigations should combine modalities such as MRI, MR spectroscopy, and peripheral physiological measures to gain a deeper insight into interconnected time- and modality-specific changes in response to ECT.

Differential Effects

SynopsisForty patients suffering from a major depressive disorder, for whom electroconvulsive therapy (ECT) was clinically indicated, were assigned to one of three electrode placement groups: bitemporal (BT), right unilateral (RU) or bifrontal (BF). Comparisons of these groups in terms of cognitive status showed that the BF placement, which avoided both temporal regions, spared both verbal and nonverbal functions. These differential effects, which were independent of the degree of clinical depression, were not, however, evident three months after the last ECT.

Induction Agents

BackgroundThe induction agent propofol is known to reduce electroconvulsive therapy (ECT) seizure duration. It is assumed that outcome from depression is adversely affected by this agent. This study compares propofol and methohexitone as induction agents for ECT.MethodIn a prospective, randomised, double-blind study 20 subjects with major depressive disorder (DSM-III-R criteria) received propofol or methohexitone anaesthesia. The Hamilton Depression Rating Scale and Beck Depression Inventory were used to assess depression before therapy, at every third treatment, and at the end of therapy. Seizure duration was measured using the cuff technique.ResultsMean seizure durations (P < 0.01) and mean total seizure duration (P < 0.01) were shorter in the propofol group. There was no difference in outcome.ConclusionsUse of propofol may not adversely affect outcome from depression and it is not necessarily contraindicated as an induction agent for ECT. Our results should be interpreted cautiously, and larger studies are needed.

The Impact

Introduction and Objective. Despite the effectiveness of electroconvulsive therapy (ECT) in treating major depressive disorder (MDD), its cognitive side effects make it less popular. This study investigated the impact of liothyronine on ECT-induced memory deficit in patients with MDD.Methodology. This is a double-blind clinical trial, in which 60 patients with MDD who were referred for ECT were selected. The diagnosis was based on the criteria of DSM-IV-TR. Patients were divided randomly into two groups to receive either liothyronine (50 mcg every morning) or placebo. After the assessment with Wechsler Memory Scale-Revised (WMS-R) before first session of ECT, posttests were repeated again, two months after the completion of ECT.Findings. By controlling the pretest scores, the mean scores of the experimental group were higher than the control group in delayed recall, verbal memory, visual memory, general memory, and attention/concentration scales (P<0.05).Conclusion. Liothyronine may prevent ECT-induced memory impairment in patients with MDD. This study has been registered in IRCT underIRCT201401122660N2.

BackgroundCurrent literature provides insufficient information on the degree of cognitive impairment during and after electroconvulsive therapy (ECT), mostly due to the fact that applied tests lacked sensitivity and flexibility. Our goal was to evaluate cognitive functioning in adult depressed patients treated with bi-temporal ECT, using tests sensitive for detection of possible acute and medium-term memory changes.MethodThirty adult patients with major depressive disorder, treated with a course of bi-temporal ECT, underwent clinical and cognitive measurements three times: at baseline, immediately after a course of ECT, and 1 month later. For cognition assessment, we used learning and visual, spatial and figural memory tests from the Cambridge Neuropsychological Test Automated Battery (CANTAB).ResultsBi-temporal ECT has proven to be an effective treatment. The linear mixed model, used to analyze changes in depression severity and patients’ cognitive performances over time and to assess dynamic correlations between aforementioned features, did not show any significant memory impairment as a potential acute or medium-term ECT effect. However, it yielded significant improvement on visual memory and learning at the follow-up, which positively correlated with the improvement of depression.ConclusionGood progress is being made in the search for ECT-related acute and medium-term cognitive side-effects by using the tests sensitive to detect memory dysfunction with parallel forms of the tasks (to counter practice effects on repeat testing). Our results on learning and memory in relation to ECT during treatment of depression did not bring forth any prolonged and significant bi-temporal ECT-related memory deficit.

Abstract Background: Although the acupuncture treatment of major depressive disorder(MDD) has been recognized by the latest clinical practice guidelines of the American Academy of Internal Medicine, complex therapeutic mechanisms need further to clarify. The aim of the study is investigate whether the aberrant resting state brain network in MDD patients could be regulated by acupuncture at GV20 using functional magnetic resonance imaging(fMRI) combined with degree centrality(DC) method. Results: Compared to healthy subjects, MDD patients exhibited significantly aberrant DC in widely brain regions, including cortical(PFC, precuneus, temporal, insula) and sub-cortical (thalamus, putamen and caudate) structures. Furthermore, results showed that acupuncture at GV20 induced down-regulation the DC of abnormal brain regions in MDD patients. Conclusions: Our findings provide imaging evidence to support that GV20-related acupuncture stimulation may modulate the abnormal brain function state in MDD patients by using fMRI technique combined with DC analysis. This study may partly interpret the neural mechanisms of acupuncture at GV20 which is used to treat patients with MDD in clinical. Trial registration: ChiCTR, ChiCTR-IOR-15006357.
