Trajectory of associative memory impairment during electroconvulsive therapy in depression

Memory impairment is a serious cognitive side effect of electroconvulsive therapy (ECT) in the treatment of major depressive episodes (MDEs) and has garnered widespread attention in clinical practice, but its underlying evolution pattern during the course of ECT remains rarely understood in detail. Associative memory (AM) is a core indicator that reflects memory impairment in ECT. This study aimed to identify the dynamic trajectory of AM impairment and explore associated predictive factors. 405 intensive longitudinal AM data from 81 patients with MDE were collected at the baseline, after the first, third, fifth, and eighth ECT using five sets of face-cued word memory paradigms. Changes in AM score over time were analyzed using a linear mixed effects model. Trajectory subgroups and predictive factors were investigated using growth mixture model and logistic regression. AM score during ECT were significantly lower than at baseline, with the lowest scores observed after the eighth ECT session. Two trajectories of rapid (N = 56, 69.14%) and slow (N = 25, 30.86%) AM impairment were differentiated. Older female with lower education level were significant predictors contributing to more rapid memory impairment for ECT. The evolving pattern of associative memory impairment during ECT appears to occur early and worsen with subsequent treatment. This study may provide the important evidence understanding of the number effect of ECT sessions on memory impairment and suggest individual factors for predicting ECT memory outcome.

Prognostic Factors and Incidence for Postictal Agitation After Electroconvulsive Therapy: A Systematic Review and Meta-analysis.

Postictal agitation (PIA) is an adverse effect of electroconvulsive therapy (ECT) and is known to predict other side effects of ECT, but inconsistencies in the literature remain regarding PIA prognostic factors and incidence. Therefore, a systematic review and meta-analysis were conducted (1) to identify prognostic factors for PIA following ECT and (2) to elucidate the diverse incidences of PIA following ECT based on demographic and clinical characteristics. Specifically, electronic databases were searched for retrospective observational studies and randomized controlled trials (RCTs) that objectively reported PIA incidence. Additional inclusion criteria encompassed studies involving patients 18 years or older and allowed for the extraction of PIA prognostic factors. This resulted in the inclusion of 21 articles with 66,047 patients in total. A total of 35 prognostic factors were identified for PIA after ECT, consisting of 8 anesthesia-related, 19 patient-related, and 8 ECT-related prognostic factors. A meta-analysis was conducted for 7 prognostic factors. None of the prognostic factors demonstrated a significant effect on reducing or increasing PIA incidence. Mean PIA was 13.9% (18.0% adjusted) at the patient level and 12.4% (16.5% adjusted) at the session level. Overall risk of bias was generally moderate to low, except in the outcome measurement domain, where 43% of the studies had a high risk of bias. Although none of the prognostic factors in meta-analysis were significant, several other prognostic factors consistently indicated increased or decreased risk, providing direction for future research. A scarcity of (high-quality) data emphasizes the need for additional research on this topic to be conducted.

Electroconvulsive Therapy (ECT): A Scotland Wide Naturalistic Study of 4,826 treatment episodes

IntroductionDespite its apparent efficacy in the treatment of a range of psychiatric disorders, electroconvulsive therapy (ECT) is viewed by some as a contentious treatment. Although most clinicians and researchers consider ECT a safe and effective treatment, there are ongoing and significantly publicised concerns about potential side effects.ObjectivesTo explore use of ECT across Scotland in a large naturalistic clinical sample across an 11-year period from 2009 to 2019. To consider the efficacy and side effects of ECT for a range of common psychiatric disorders including, depression, bipolar depression, schizophrenia, and mania.MethodsUsing data from the Scottish Electroconvulsive Therapy (ECT) Accreditation Network (SEAN), information was collected for all adults who had received ECT. Variables included age, sex, Scottish Index of Multiple Deprivation (SIMD) quintile, International Classification of Diseases, Tenth Edition (ICD-10) diagnosis, indication for ECT, Mental Health Act status, consent status, entry and exit Montgomery-Asberg Depression Rating Scores (MADRS), entry and exit Clinical Global Index Severity CGI-S) scores and reported side effects. Side effects were recorded as present if the side effect was reported at any point during the episode of treatment.Results4826 ECT episodes were recorded. The majority of episodes were in women (68.4%, n=3,301). Average age at treatment onset was 58.52 years. Males were slightly younger (m=58.24 years vs f= 58.65 years, p= 0.20). Mean number of treatments/episode was 9.59 (95% CI 9.32 – 9.85). Mean treatment dose delivered was 277.75mC (95%CI 272.88 – 282.63mC).2920 episodes of treatment had CGI-S entry and exit recorded. At entry, mean CGI-S indicated marked illness (5.03 95% CI 4.99-5.07). Recipients with schizophrenia had the highest CGI-S score (5.45 95% CI 5.21-5.60), followed by those with post-partum disorders (5.38, 95% CI 4.61-6.14). At exit, mean CGI scores indicated borderline illness (2.07, 95% CI 2.03-2.11), recipients diagnosed with mixed affective state had the lowest CGI-S score (1.72, 95% CI 0.99-2.47) followed by those with schizoaffective disorder (2.01, 95% CI 1.76-2.42).Anaesthetic complications (n=34) and prolonged seizures (n=38) were rare, occurring in <1% of treatment episodes. Cardiovascular complications were reported in 2.2% (n= 102). Nausea was reported in 7.2% (n= 334) and muscle aches in 12% (n=560). Confusion was reported in 19% (n=879) and cognitive side effects were reported in 26.2% (n=1212). One third of treatment episodes reported confusion or cognitive side effects (33.1%, n=1545).ConclusionsFrom this large naturalistic clinical sample, ECT appears to be effective in improving illness severity as measured by CGI-S score. While some side effects (such as prolonged seizures and cardiovascular complications) were rare, others (such as confusion or cognitive side effects) were relatively common.Disclosure of InterestNone Declared

Assessing the Efficacy of Methods for Treatment-Resistant Depression: A Review

Electroconvulsive Therapy (ECT), Transcranial Magnetic Stimulation (TMS), and Esketamine have all been proven to be effective against treatment-resistant depression (TRD). However, it is still unclear which method of treatment is the most effective both in general and in specific populations of patients exhibiting certain traits (i.e. psychosis) or with varied severities of TRD. ECT is the oldest form of treatment and has been proven effective, though not without significant side effects. TMS has also been shown to be effective, but without the side effects of ECT. Esketamine is the newest form of treatment for TRD, only having been approved by the FDA in 2019. Although current research demonstrates its efficacy, little research has been done on this modality because of its novelty. Trials from 2000-2019 were searched for and utilized to examine the efficacy of these three treatments in comparison to each other. The most recent and relevant studies were chosen. Studies completed before 2000 or utilizing patients without qualifying criteria for TRD were not included in our review. The data analyzed suggest that ECT is the most effective form of treatment overall, but TMS is noninferior in nonpsychotic patients and esketamine is effective for patients with TRD and no other chronic comorbidities.

Safety of Electro-Convulsive Therapy in Combination with Duloxetine in Treatment-resistant Depressive Patients: A Randomized Clinical Trial

Background: There are several strategies in the management of treatment-resistant depression (TRD), including the administration of other antidepressants, augmentation therapy, electro-convulsive therapy (ECT), and a combination of ECT and antidepressants. The safety of ECT combined with any medication must be confirmed. The aim of this study was to assess the safety of duloxetine and ECT combination therapy. Materials and Methods: In this randomized clinical trial, the probable side effects of ECT plus duloxetine were compared with ECT plus sertraline in two groups of admitted TRD patients. Patients with general medical diseases and/or any contraindications to ECT or any of the two drugs were excluded. General side effects, including nausea, vomiting, and headache reported by patients (hours after ECT) as well as cardiotoxicity by electrocardiogram (immediately after any ECT episode), cognitive status by mini-mental state examination (MMSE, one month after the last ECT), and seizure duration were recorded for each patient. Results: No significant differences were observed in nausea, vomiting, headache, and myalgia between ECT+duloxetine and ECT+sertraline groups. Heart rate, QTc interval, ST-T change, and the incidence of arrhythmia were the same between the two arms of the study. Also, no prolonged seizures and status epilepticus were recorded among the studied patients. The MMSE revealed no marked differences in the cognitive status among patients of the two groups. Conclusion: ECT+duloxetine and ECT+sertraline were equally safe in patients with TRD.

Effect of erythropoietin on cognitive side-effects of electroconvulsive therapy in depression: A randomized, double-blind, placebo-controlled trial

Electroconvulsive therapy (ECT) is one of the most effective and rapid-acting treatment for severe depression but is associated with cognitive side-effects. Identification of add-on treatments that counteract these side-effects would be very helpful. This randomized, double-blinded, placebo-controlled, parallel-group study investigated the effects of four add-on erythropoietin (EPO; 40,000 IU/ml) or saline (placebo) infusions over 2.5 weeks of ECT (eight ECT sessions) in severely depressed patients with unipolar or bipolar depression. Neuropsychological assessments were conducted pre-ECT, three days after the eighth ECT (week 4), and at a 3-month follow-up. Further, functional magnetic resonance imaging (fMRI) was conducted after the eighth ECT. The primary outcome was change from pre- to post-ECT in a ‘speed of complex cognitive processing’ composite. Secondary outcomes were verbal and autobiographical memory. Of sixty randomized patients, one dropped out before baseline. Data were thus analysed for 59 patients (EPO, n = 33; saline, n = 26), of whom 28 had fMRI data. No ECT-related decline occurred in the primary global cognition measure (ps≥0.1), and no effect of EPO versus saline was observed on this outcome (ps≥0.3). However post-ECT, EPO-treated patients exhibited faster autobiographical memory recall than saline-treated patients (p = 0.02), which was accompanied by lower memory-related parietal cortex activity. The absence of global cognition changes with ECT and EPO, coupled with the specific impact of EPO on autobiographical memory recall speed and memory-related parietal cortex activity, suggests that assessing autobiographical memory may provide increased sensitivity in evaluating and potentially preventing cognitive side-effects of ECT.

The myth of brain damage: no change of neurofilament light chain during transient cognitive side-effects of ECT

Electroconvulsive therapy (ECT) is an effective, safe, and mostly well-tolerated treatment for patients with severe or difficult to treat depression or psychotic disorders. However, a relevant number of patients experience subjective and/or objective cognitive side-effects. The mechanism of these transient deficits is not yet clear. Thus, our study prospectively investigated neurofilament light chain (NfL) concentrations as a highly sensitive biomarker for neuroaxonal damage along with cognitive performance during a course of ECT. Serum NfL concentrations from 15 patients with major depressive disorder receiving ECT were analyzed (1) 24 h before the first ECT, (2) 24 h and (3) 7 days after the last ECT (45 measurements in total). Neuropsychological testing including memory, executive functions and attention was performed at each time-point. NfL concentrations did not change between the three time-points, while a temporary cognitive impairment was found. Even in the subset of patients with the strongest impairment, NfL concentrations remained unchanged. Neuropsychological testing revealed the common pattern of transient cognitive side-effects with reduced performance 24 h post-ECT (global cognition score: p < 0.001; memory: p = 0.043; executive functions: p = 0.002) and return to baseline after 7 days (all p < 0.001). Our study adds to the evidence that neither ECT per se nor the transient cognitive side-effects seem to be associated with an increase of NfL as a marker of neuroaxonal damage. In contrast, we discuss cognitive side effects to be potentially interpreted as a byproduct of ECT’s neuroplastic effects.

Response rate and safety of antidepressants combined with electroconvulsive therapy in adolescent depression: Real-world clinical application

Background•Currently, electroconvulsive therapy (ECT) is less commonly used to treat adolescent depression than adult depression, owing to a limited evidence base in the medical literature. MethodsThis study included 210 depression patients receiving antidepressants and ECT. The symptoms of depression were examined with the Hamilton Depression Scale (HAMD) and Clinical Global Impressions Scale (CGI) at baseline and the end of treatment. Response and safety were compared among adolescent and adult patients. ResultsFor adolescents, the response rate (much improved or very much improved) was 80.9 %, and CGI-Severity (CGI-S), HAMD, and suicide factor scores were significantly changed as compared to baseline (P < 0.001), results of which were similar to the adult group. There were no significant differences in HAMD, CGI scores between adolescent and adult depression before or after treatment (P > 0.05). Notably, adolescents expressed stronger suicidal intent than adults, and ECT observably relieved it. Side effects (memory problems, headache, nausea/vomiting, muscle soreness) in adolescents were not statistically different from those in adults (P > 0.05). LimitationsAs data were derived from a single center, the generalizability of results may be limited, and the potential factors affecting the efficacy of ECT were not further explored. ConclusionAntidepressants combined with ECT are associated with high response rate and safety for treating depression, regardless of age. A stronger expression of suicide ideation was observed in depressed adolescents, and side effects of ECT were similar to the adults.

Clinical Improvement in Depression and Cognitive Deficit Following Electroconvulsive Therapy.

Electroconvulsive therapy (ECT) is a long-standing treatment choice for disorders such as depression when pharmacological treatments have failed. However, a major drawback of ECT is its cognitive side effects. While numerous studies have investigated the therapeutic effects of ECT and its mechanism, much less research has been conducted regarding the mechanism behind the cognitive side effects of ECT. As both clinical remission and cognitive deficits occur after ECT, it is possible that both may share a common mechanism. This review highlights studies related to ECT as well as those investigating the mechanism of its outcomes. The process underlying these effects may lie within BDNF and NMDA signaling. Edema in the astrocytes may also be responsible for the adverse cognitive effects and is mediated by metabotropic glutamate receptor 5 and the protein Homer1a.

Possible Solutions to Depression Using BCI Methods

According to the research results of 2022, the blue book of depression in China, there exists about 95,00,000 depression patients in China and the number is still growing. Depression is becoming an increasingly severe disease. As it is generally believed that the etiology of depression is multifaceted, related to gender differences, chronic stress, dietary behavior, and the abuse of drugs and alcohol. Clinical treatment is mainly on drugs, but BCI methods cannot be ignored. Compared to traditional methods, the BCI methods like Electroconvulsive therapy (ECT), repetitive Transcranial Magnetic Stimulation (rTMS) or Deep Brain Stimulation (DBS), DBS has many advantages, for patients whose physical conditions are not very ideal, the side effect of drugs may lead to serious conditions. in this paper is mainly focused on the use of BCI including technical background, applicable crowd, taboos and sequels. In the end of the passage some data from clinical cases would be discussed to give a specific impression about the methods. Then a possible scheme would be apposed about a possible solution to avoid triggering the side-effect of ECT in clinical conditions.

Transient Fever Response After ECT in a Patient with Catatonic Schizophrenia: A Case Report.

Electroconvulsive therapy (ECT) is an effective and safe treatment method for many psychiatric disorders. In general medical practice, ECT may cause side effects as most other treatment methods do. Headache, myalgia, nausea, vomiting, confusion, anterograde amnesia are common side effects of electroconvulsive therapy. Fever; in addition to general medical conditions such as infection, malignancy, connective tissue diseases, drug treatments, malignant hyperthermia, convulsions, it can also occur due to conditions such as neuroleptic malignant syndrome (NMS), serotonin syndrome, catatonia, malignant catatonia, which are frequently encountered in psychiatry clinics. In the literature, transient fever response due to electroconvulsive therapy application have been described, albeit rarely. Although there are many proposed mechanisms for the emergence of a fever response, regardless of its cause, it is still not understood why some fever responses occur. In this article, we present the differential diagnosis of the fever response, possible causes, and the mechanisms that may reveal the secondary fever response to electroconvulsive therapy in a case with a diagnosis of catatonic schizophrenia, who developed a fever response during electroconvulsive therapy sessions and no fever response was observed at times other than electroconvulsive therapy sessions. In this case, postictal benign fever response associated with electroconvulsive therapy was considered after excluding other medical conditions that may cause a fever response after electroconvulsive therapy. Keywords: ECT, Fever, Catatonia, NMS.

Cerebral perfusion is related to antidepressant effect and cognitive side effects of Electroconvulsive Therapy

BackgroundThe mechanisms underlying the antidepressant effect and cognitive side effects of Electroconvulsive Therapy (ECT) remain elusive. The measurement of cerebral perfusion provides an insight into brain physiology. ObjectiveWe investigated ECT-related perfusion changes in depressed patients and tested whether these changes correlate with clinical effects. MethodsA sample of 22 in-patients was examined at three time points: 1) within two days before, 2) within one week after, and 3) six months after an ECT series. Cerebral perfusion was quantified using arterial spin labeling magnetic resonance imaging. The primary regions of interest were the bilateral dorsolateral prefrontal cortices (DL-PFC) and hippocampi. The depression severity was assessed by the six-item Hamilton Depression Rating Scale, and cognitive performance by the Screen for Cognitive Impairment in Psychiatry. A linear mixed model and partial correlation were used for statistical analyses. ResultsFollowing an ECT series, perfusion decreased in the right (−6.0%, p = .01) and left DL-PFC (−5.6%, p = .001). Perfusion increased in the left hippocampus (4.8%, p = .03), while on the right side the increase was insignificant (2.3%, p = .23). A larger perfusion reduction in the right DL-PFC correlated with a better antidepressant effect, and a larger perfusion increase in the right hippocampus with worse cognitive impairment. ConclusionECT-induced attenuation of prefrontal activity may be related to clinical improvement, whereas a hippocampal process triggered by the treatment is likely associated with cognitive side effects.

High-frequency repetitive transcranial magnetic stimulation alleviates the cognitive side effects of electroconvulsive therapy in major depression.

ObjectiveThe retrospective study aimed to explore the difference in mood outcomes and cognitive function between high-frequency repetitive transcranial magnetic stimulation (HF-rTMS) over dorsolateral prefrontal cortex (DLPFC) and electroconvulsive therapy in major depression disorder (MDD) patients and to examine the improvement of HF-rTMS on cognitive impairment evoked by electroconvulsive therapy (ECT).Materials and methodsA total of 116 participants with MDD, who completed a 4-week follow-up assessment, were enrolled. The cohort consisted of 26 cases classed as control, 46 participants administrated with HF-rTMS (HF-rTMS group), 22 patients treated with ECT (ECT group), and 23 cases treated with HF-rTMS and ECT at the course of hospitalization (HF-rTMS + ECT group). Medication was kept constant as well in all participants. The 17-item Hamilton Depression Rating Scale for Depression (HAMD-17) and 14-item Hamilton Anxiety Rating Scale (HAMA-14) were used to assess depression and anxiety, respectively. Montreal Cognitive Assessment (MoCA) was to elevate cognitive function.ResultsNo statistical significance was found for baseline in sociodemographic, characteristics of depression, anxiety and cognition, and psychopharmaceutic dosages among control, HF-rTMS, ECT, and HF-rTMS + ECT groups (p > 0.05). Compared with baseline level, total scores of HAMD-17 and HAMA-14 significantly decreased at the end of 4 weeks after treatment (p < 0.001). Furthermore, the decline in scores of HAMD-17 and its sleep disorder and retardation factors from baseline to post-treatment was greater in HF-rTMS, ECT, and HF-rTMS + ECT group than in control (p < 0.05), and there was a significant difference between control and HF-rTMS group in the decline of psychological factor of HAMA-14 (p < 0.01). ECT treatment evoked total score of MoCA to decrease significantly at the end of 4-week after intervention (p < 0.001), and the decline in scores of MoCA and its delayed recall and language performances from baseline to post-treatment was greater in ECT than control, HF-rTMS, and HF-rTMS + ECT (p < 0.05).ConclusionHigh-frequency repetitive transcranial magnetic stimulation improved psychological anxiety and ameliorated the cognition impairment evoked by ECT though it had the same anti-depressant efficacy as ECT.

Rivastigmine for ECT-induced cognitive adverse effects in late life depression (RECALL study): A multicenter, randomized, double blind, placebo-controlled, cross-over trial in patients with depression aged 55 years or older: Rationale, objectives and methods.

BackgroundCognitive side-effects are an important reason for the limited use of electroconvulsive therapy (ECT). Cognitive side-effects are heterogeneous and occur frequently in older persons. To date, insight into these side-effects is hampered due to inconsistencies in study designs and small sample sizes. Among all cognitive side-effects, confusion and delirious states are especially troublesome for patients, relatives and clinicians. In particular inter-ictal delirium-like states are worrisome, since they may lead to premature treatment discontinuation. Besides a need for further insight into determinants of cognitive side-effects of ECT, there is a great need for treatment options.Methods and designThe Rivastigmine for ECT-induced Cognitive Adverse effects in Late Life depression (RECALL) study combines a multicenter, prospective cohort study on older patients with depression, treated with ECT, with an embedded randomized, placebo-controlled cross-over trial to examine the effect of rivastigmine on inter-ictal delirium. Patients are recruited in four centers across the Netherlands and Belgium. We aim to include 150 patients into the cohort study, in order to be able to subsequently include 30 patients into the trial. Patients are included in the trial when inter-ictal delirium, assessed by the Confusion Assessment method (CAM), or a drop in Mini Mental State Examination (MMSE) score of ≥4 during ECT, develops. In the cohort study, comprehensive measurements of ECT-related cognitive side-effects—and their putative determinants—are done at baseline and during the ECT-course. The primary outcome of the clinical trial is the effectiveness of rivastigmine on inter-ictal delirium-severity, assessed with a change in the Delirium Rating Scale-Revised-98. Secondary outcomes of the clinical trial are several ECT-characteristics and side-effects of rivastigmine.DiscussionThis study is the first clinical trial with a focus on ECT-induced, inter-ictal delirium. The cohort provides the basis for recruitment of patients for the cross-over trial and additionally provides an excellent opportunity to unravel cognitive side-effects of ECT and identify putative determinants. This paper describes the rationale and study protocol.Clinical trial registrationEudraCT 2014-003385-24.

Pharmacological interventions to diminish cognitive side effects of electroconvulsive therapy: A systematic review and meta-analysis.

ObjectiveThe authors conducted a systematic review and meta‐analysis of pharmacological interventions to diminish cognitive side effects of ECT.MethodsElectronic databases of Pubmed, PsycInfo, Embase and Scopus were searched from inception through 1 April, 2021, using terms for ECT (e.g. electroconvulsive therapy), cognitive outcome (e.g. cogni*) and pharmacological intervention (e.g. calcium channel blocker and general terms, like protein). Original studies with humans receiving ECT were included, which applied pharmacological interventions in comparison with placebo or no additive intervention to diminish cognitive side effects. Data quality was assessed using Risk of Bias and GRADE. Random‐effects models were used. PROSPERO registration number was CRD42021212773.ResultsQualitative synthesis (systematic review) showed 52 studies reporting sixteen pharmacological intervention‐types. Quantitative synthesis (meta‐analysis) included 26 studies (1387 patients) describing twelve pharmacological intervention‐types. Low‐quality evidence of efficacy was established for memantine (large effect size) and liothyronine (medium effect size). Very low‐quality evidence shows effect of acetylcholine inhibitors, piracetam and melatonin in some cognitive domains. Evidence of no efficacy was revealed for ketamine (very low‐quality), herbal preparations with anti‐inflammatory properties (very low to low‐quality) and opioid receptor agonists (low‐quality).ConclusionMemantine and liothyronine are promising for further research and future application. Quality of evidence was low because of differences in ECT techniques, study populations and cognitive measurements. These findings provide a guide for rational choices of potential pharmacological intervention research targets to decrease the burden of cognitive side effects of ECT. Future research should be more uniform in design and attempt to clarify pathophysiological mechanisms of cognitive side effects of ECT.

Cerebral Perfusion is Related to Antidepressant Effect and Cognitive Side Effects of Electroconvulsive Therapy

Cerebral Perfusion is Related to Antidepressant Effect and Cognitive Side Effects of Electroconvulsive Therapy

The Cardiovascular Side Effects of Electroconvulsive Therapy and Their Management.

Electroconvulsive therapy (ECT) remains stigmatized in the broader medical community because of misunderstandings about treatment procedures, mortality rates, and cardiovascular complications. Electroconvulsive therapy causes periprocedural hemodynamic variability because of the surges in parasympathetic and sympathetic nervous systems after the administration of the electrical charge. Patients experience an increase in cardiac workload, which is potentially dangerous for patients with preexisting heart disease. Several findings suggest that cardiac complications occur most frequently in patients with underlying cardiovascular disease. We describe the cardiovascular complications that may result from ECT treatment and offer insight on how to mitigate these concerns if they occur. PubMed was queried using terms "electroconvulsive therapy" and "cardiovascular adverse effects." A table is provided with the common cardiovascular side effects of ECT and the most recent evidence-based treatment strategies to manage them. Generally, ECT is a safe procedure in which complications are minor and manageable. Most major complications caused by ECT are related to the cardiovascular system; however, with an appropriate pre-ECT evaluation and a comprehensive multidisciplinary team approach, the cardiovascular complications can be well managed and minimized. Providing proper cardiac clearance can prevent cardiac complications and provide timely care to treatment-resistant populations who are at risk for excessive morbidity and suicide.

Repetitive transcranial magnetic stimulation treatment for peripartum depression: systematic review & meta-analysis

BackgroundPeripartum depression is a common disorder with very high potential hazards for both the patients and their babies. The typical treatment options include antidepressants and electroconvulsive therapy. However, these treatments do not ensure the safety of the fetus. Recently, repetitive transcranial magnetic stimulation has emerged as a promising treatment for neuropathies as well as depression. Nevertheless, many studies excluded pregnant women. This systematic review was conducted to confirm whether repetitive transcranial magnetic stimulation was a suitable treatment option for peripartum depression.MethodsWe performed a systematic review that followed the PRISMA guidelines. We searched for studies in the MEDLINE, PsycINFO, EMBASE, and Cochrane library databases published until the end of September 2020. Eleven studies were selected for the systematic review, and five studies were selected for quantitative synthesis. Data analysis was conducted using Comprehensive Meta-Analysis 3 software. The effect size was analyzed using the standardized mean difference, and the 95% confidence interval (CI) was determined by the generic inverse variance estimation method.ResultsThe therapeutic effect size of repetitive transcranial magnetic stimulation for peripartum depression was 1.394 (95% CI: 0.944–1.843), and the sensitivity analysis effect size was 1.074 (95% CI: 0.689–1.459), indicating a significant effect. The side effect size of repetitive transcranial magnetic stimulation for peripartum depression was 0.346 (95% CI: 0.214–0.506), a meaningful result. There were no severe side effects to the mothers or fetuses.ConclusionsFrom various perspectives, repetitive transcranial magnetic stimulation can be considered an alternative treatment to treat peripartum depression to avoid exposure of fetuses to drugs and the severe side effects of electroconvulsive therapy. Further research is required to increase confidence in the results.

Cognitive remediation following electroconvulsive therapy in patients with treatment resistant depression: randomized controlled trial of an intervention for relapse prevention \u2013 study protocol

BackgroundMajor depressive episode (MDE) is worldwide one of the most prevalent and disabling mental health conditions. In cases of persistent non-response to treatment, electroconvulsive therapy (ECT) is a safe and effective treatment strategy with high response rates. Unfortunately, longitudinal data show low sustained response rates with 6-month relapse rates as high as 50% using existing relapse prevention strategies. Cognitive side effects of ECT, even though transient, might trigger mechanisms that increase relapse in patients who initially responded to ECT. Among these side effects, reduced cognitive control is an important neurobiological driven vulnerability factor for depression. As such, cognitive control training (CCT) holds promise as a non-pharmacological strategy to improve long-term effects of ECT (i.e., increase remission, and reduce depression relapse).Method/designEighty-eight patients aged between 18 and 70 years with MDE who start CCT will be included in this randomized controlled trial (RCT). Following (partial) response to ECT treatment (at least a 25% reduction of clinical symptoms), patients will be randomly assigned to a computer based CCT or active placebo control. A first aim of this RCT is to assess the effects of CCT compared to an active placebo condition on depression symptomatology, cognitive complaints, and quality of life. Secondly, we will monitor patients every 2 weeks for a period of 6 months following CCT/active placebo, allowing the detection of potential relapse of depression. Thirdly, we will assess patient evaluation of the addition of cognitive remediation to ECT using qualitative interview methods (satisfaction, acceptability and appropriateness). Finally, in order to further advance our understanding of the mechanisms underlying effects of CCT, exploratory analyses will be conducted using video footage collected during the CCT/active control phase of the study.DiscussionCognitive remediation will be performed following response to ECT, and an extensive follow-up period will be employed. Positive findings would not only benefit patients by decreasing relapse, but also by increasing acceptability of ECT, reducing the burden of cognitive side-effects.Trial registrationThe study is registered with ClinicalTrials.gov. Study ID: NCT04383509Trial registration date: 12.05.2020.
