Abstract
OBJECTIVES Electroconvulsive therapy (ECT) and repetitive transcranial magnetic stimulation (rTMS) are both effective in treating depression. Although rTMS induces fewer adverse effects, its effectiveness relative to ECT is not well established. The aim of this study was to investigate the treatment outcomes of ECT and rTMS in patients who have received both interventions. METHODS This was a register-based observational crossover study in patients with depression who had undergone ECT and rTMS in Sweden between 2012 and 2021. Primary outcome was reduction in the Montgomery-Åsberg Depression Rating Scale-Self-report (MADRS-S) score. Secondary outcome was response defined as a 50% or greater decrease in the MADRS-S score. Subgroup analyses were performed to identify factors that predicted differential responses between rTMS and ECT. Continuous and categorical variables were analyzed using paired-samples t tests and McNemar tests, respectively. RESULTS In total, 138 patients across 19 hospitals were included. The MADRS-S score after ECT and rTMS was reduced by 15.0 and 5.6 ( P = 0.0001) points, respectively. Response rates to ECT and rTMS were 38% and 15% ( P = 0.0001), respectively. Electroconvulsive therapy was superior across all subgroups classified according to age and severity of depression. CONCLUSIONS Our results suggest that ECT is more effective than rTMS in treating depression among patients who have received both interventions. Age and baseline depression severity did not predict who would similarly benefit from rTMS and ECT.

Abstract
INTRODUCTION The safety of electroconvulsive therapy has improved greatly over the last decades, making the potentially adverse effects on memory and other neurocognitive functions the main clinical aspect of concern in the present. In Colombia, the general population and healthcare professionals (even some psychiatrists) seem to have mostly negative opinions towards electroconvulsive therapy treatment, but maybe this could be reconsidered if more information is provided; therefore, the aim of the present study was to evaluate the changes in memory and the severity of the symptoms in a group of patients with severe depression before and after electroconvulsive therapy. METHODS Twenty-three patients ranging in age from 23 to 70 years from the electroconvulsive therapy service at the San Juan de Dios Clinic (Manizales, Colombia) were recruited in order to assess the effect of electroconvulsive therapy on memory in patients with severe depression. Depressive symptoms and memory were assessed with the Hamilton Depression Scale (HAMD) and Rey Auditory Verbal Learning Test (RAVLT), respectively. The assessment was administered to participants before the initial treatment of electroconvulsive therapy series (0-1 day) and 2 days after their last treatment. RESULTS Electroconvulsive therapy resulted in significant improvement in the rating of depression. There were no significant differences in the five learning trials, delayed recall, learning and forgetting scores from pre-treatment to post-treatment. Significant pre-treatment/post-treatment differences were found in the delayed recognition trial. CONCLUSIONS Pre- and post- electroconvulsive therapy cognitive assessment is a feasible and useful procedure. In general, memory performance does not worsen after electroconvulsive therapy in patients with depression. Only delayed recognition is affected a few days following electroconvulsive therapy, particularly in patients with low educational level and bitemporal (BT) electrode placement.

Abstract
INTRODUCTION Bipolar disorder (BD) is a chronic mental illness impacting 1-2% of the population worldwide and causing high rates of functional impairment. Patients with BD spend most of their time in depressive episodes and up to one-third of patients do not respond to adequate doses of medications. Although no consensus exists for definition of treatment-resistant bipolar depression (TRBD), failure of symptoms improvement despite an adequate trial of two therapeutic agents is a common theme of TRBD. In this paper, we review the evidence base of therapeutic interventions, challenges, and potential future directions for TRBD. METHODS We conducted a literature search for randomized controlled trials on PubMed for the treatment of TRBD and ongoing trials for the treatment of TRBD/bipolar depression on clinicaltrials.gov. RESULTS Several therapeutic agents have been investigated for TRBD. Adjunctive pramipexole and modafinil have data supporting short-term efficacy in TRBD, along with limited data for racemic intravenous ketamine. Celecoxib augmentation of escitalopram and treatment with metformin in patients with insulin resistance showed promising results. Right unilateral electroconvulsive therapy displayed statistically significant response rate and improvement, but not remission compared to pharmacotherapy. Trials for transcranial magnetic stimulation (TMS) have failed to show a significant difference from sham treatment in TRBD. FUTURE TRENDS Pharmacological treatments with novel mechanisms of actions like brexpiprazole and vortioxetine are being investigated following successes in unipolar depression. Modified TMS protocols such as accelerated TMS are under investigation. Innovative approaches like psychedelic-assisted psychotherapy, interleukin-2, fecal microbiota transplantation and multipotent stromal cells are being studied. CONCLUSION Evidence on current treatment modalities for TRBD is limited with low efficacy. More research is needed for successful treatment of TRBD. Effective therapies and innovative approaches to treatment are being investigated and could show promise.

Abstract
Background and Objectives: Unstable mixed episodes or rapid switching between opposite affective poles within the scope of short cycles was first characterized in 1967 by S. Mentzos as complex polymorphous states with chaotic overlap of manic and depressive symptoms. Well-known examples include antidepressant-induced mania/hypomania and rapid/ultra-rapid/ultradian cycling, when clinicians observe an almost continuous mixed state with a constant change of preponderance of manic or depressive symptoms. Achieving stable remission in these cases is challenging with almost no data on evidence-based treatment. When mood stabilizers are ineffective, electroconvulsive therapy (ECT) has been suggested. Objectives: After reviewing the evidence from available literature, this article presents our own clinical experience of ECT efficacy and tolerability in patients with ultra-rapid cycling bipolar disorder (BD) and unstable mixed states. Materials and Methods: We conducted an open, one-year observational prospective study with a "mirror image" design, including 30 patients with rapid and ultra-rapid cycling BD on long-term mood stabilizer treatment (18 received lithium carbonate, 6 on valproate and 6 on carbamazepine) with limited effectiveness. A bilateral ECT course (5-10 sessions) was prescribed for regaining mood stability. Results: ECT was very effective in 12 patients (40%) with a history of ineffective mood stabilizer treatment who achieved and maintained remission; all of them received lithium except for 1 patient who received carbamazepine and 2 with valproate. Nine patients (30%) showed partial response (one on carbamazepine and two on valproate) and nine patients (30%) had no improvement at all (four on carbamazepine and two on valproate). For the whole sample, the duration of affective episodes was significantly reduced from 36.05 ± 4.32 weeks in the year prior to ECT to 21.74 ± 12.14 weeks in the year post-ECT (p < 0.001). Depressive episodes with mixed and/or catatonic features according to DSM-5 specifiers were associated with a better acute ECT response and/or long-term mood stabilizer treatment outcome after ECT. Conclusions: ECT could be considered as a useful option for getting mood instability under control in rapid and ultra-rapid cycling bipolar patients. Further randomized trials are needed to confirm these results.

Abstract
Major mood syndromes are among the most common and disabling mental disorders. However, a lack of clear delineation of their underlying pathophysiological mechanisms is a major barrier to prevention and optimised treatments. Dysfunction of the 24-h circadian system is a candidate mechanism that has genetic, behavioural, and neurobiological links to mood syndromes. Here, we outline evidence for a new clinical phenotype, which we have called 'circadian depression'. We propose that key clinical characteristics of circadian depression include disrupted 24-h sleep-wake cycles, reduced motor activity, low subjective energy, and weight gain. The illness course includes early age-of-onset, phenomena suggestive of bipolarity (defined by bidirectional associations between objective motor and subjective energy/mood states), poor response to conventional antidepressant medications, and concurrent cardiometabolic and inflammatory disturbances. Identifying this phenotype could be clinically valuable, as circadian-targeted strategies show promise for reducing depressive symptoms and stabilising illness course. Further investigation of underlying circadian disturbances in mood syndromes is needed to evaluate the clinical utility of this phenotype and guide the optimal use of circadian-targeted interventions.

Abstract
AIM Although electroconvulsive therapy (ECT) has been extensively used for depressive episodes in bipolar disorder (BDD), it has received less interest in research compared with major depressive disorder (MDD). Studies comparing the efficacy of ECT in BDD and MDD have been contradictory. This study aimed to compare the effectiveness of ECT in BDD and MDD, analyzing the influence of clinical features on outcome. METHODS The medical charts and electronic records of 107 patients (MDDn = 75 [70.1 %], BDD n = 32 [29.9 %]) receiving bi-temporal ECT were investigated retrospectively. Features of the index episode, such as the time elapsed until ECT and the effect of diagnosis on efficacy evaluated by the Hamilton Depression Rating Scale (HAM-D), were analyzed. RESULTS The diagnostic groups were alike concerning clinical features of the index episode, such as the presence of psychotic symptoms and suicidality. Patient age and the number of previous affective episodes were significantly different between the groups. The time elapsed until ECT in the examined episode was significantly longer in the MDD group. Compared with the MDD group, the BDD group had a significantly higher remission rate with ECT. Regression analysis revealed that BDD diagnosis, older age, and shorter time until ECT were significantly associated with remission. CONCLUSION The significant relationship observed between greater time elapsed until ECT and worse outcome is noteworthy in terms of clinical practice. This finding further challenges the widely accepted place of ECT as the "last resort" for the treatment of depression in bipolar and unipolar affective disorders.

Abstract
BACKGROUND The definitions of treatment-resistant bipolar disorder (TRBD) have varied across studies. Additionally, its management is clinically challenging. An updated synthesis and appraisal of the available evidence is needed. METHODS A systematic search of major electronic databases from inception up to May 25th, 2020, was conducted to identify randomized controlled trials (RCTs) of pharmacological and non-pharmacological interventions for the management of TRBD. When sufficient evidence was available, a meta-analysis was conducted. RESULTS Seventeen studies (n = 928 patients) were included in the qualitative synthesis. Fourteen studies (n = 803) assessed treatment-resistant acute bipolar depression (TRBD-De), including five neuromodulatory and nine pharmacological trials. Rapid- vs. standard up-titration of clozapine showed promising efficacy for TRBD mania, without significant adverse events. Electroconvulsive therapy (ECT) was confirmed to be similarly effective for TRBD-De as for treatment-resistant unipolar depression: odd ratio, OR = 0.919 (95%C.I. = 0.44-1.917), I2 = 13.98, p = .822. TRBD-De patients exposed to ketamine at day one post-infusion had high odds of response: OR = 10.682 (95%C.I. = 2.142-53.272), I2 = 0, p = <.005. The pooled drop-out rate in the ketamine trials was 21.2%. Additional evidence is warranted to confirm the potential efficacy of pramipexole or stimulants for TRBD-De. LIMITATIONS Publication/measurement bias; exploratory nature of the meta-analyses for interventions that included participants solely with TRBD-De. CONCLUSIONS Overall, a few interventions are available for TRBD, including pramipexole, ECT, and clozapine, among others. Larger and better-designed trials for TRBD are warranted and should be based on more uniform operational definitions. PROSPERO registration number: CRD42018114567.

Abstract
BACKGROUND Electroconvulsive therapy (ECT) is an effective treatment for acute depression, mania and mixed states. We evaluated the long-term outcome of patients with bipolar depression or mixed state, responsive to ECT. METHODS this observational follow-up study was conducted in 70 patients with Bipolar Disorder: 36 patients met DSM-IV-TR criteria for a major depressive episode (MDE) and 34 for a mixed episode (MXE). During the follow-up after ECT, the relapse rates and the duration of response and remission periods were recorded. RESULTS the mean duration of the follow-up was 57 weeks. 93% of the patients maintained at least a partial therapeutic response for more than 90% of the follow-up period. 73% of patients fulfilled the criteria for a full remission, 33% showed a depressive relapse and 10% a mixed relapse. No manic relapses occurred but almost 1/3 of the sample presented hypomanic episodes. MDE patients presented higher rates of remission compared to MXE ones. Patients with anxiety disorders reported earlier relapses than those without this comorbidity. Relapsed-patients showed higher functional impairment at baseline evaluation, compared to non-relapsed ones. LIMITATIONS nonrandom allocation, limited sample size, possible influence of psychopharmacological treatment. CONCLUSIONS Given several methodological limitations, this study cannot draw definite conclusions but could suggest that in treatment-resistant bipolar patients with severe depression or mixed state, ECT may represent a useful treatment option. Patients with mixed features, comorbid anxiety disorders and higher functional impairment present less favorable outcome. Future research on long-term efficacy of ECT and on clinical predictors of relapse is needed.

Abstract
Since the first publication of the guideline in 2012, which included critically reviewed evidence up to 2010, several hundred articles with new evidence were published and some topics of the clinical consensus needed to be reconsidered. Therefore, it was urgently necessary to revise the guideline to bring them up to date. In this article important revisions and updates are presented and the chances and limitations of the development of the guidelines and their implementation are discussed.

Abstract
OBJECTIVE Electroconvulsive therapy (ECT) is used in patients with severe forms of bipolar depression. ECT is effective but not all patients respond. The aim of this study was to determine prognostic factors for response to ECT in patients hospitalized for bipolar depression. METHODS Data were obtained from several national Swedish registers. All patients with bipolar depression treated with ECT in any hospital in Sweden between 2011 and 2016 for whom information about ECT response was available were included (n = 1251). Response was defined as a score on the Clinical Global Impression - Improvement scale of one or two. Univariate and multivariate logistic regression were conducted to investigate associations between socio-demographic and clinical factors and response. RESULTS Response was achieved in 80.2% patients. Older age was associated with higher response rate to ECT. Patients with comorbid obsessive-compulsive disorder or personality disorder, and patients previously treated with lamotrigine had lower response rate. CONCLUSION Electroconvulsive therapy for bipolar depression was associated with very high response rates. The strongest prognostic factors were higher age, absence of comorbid obsessive-compulsive disorder or personality disorder, and less prior pharmacologic treatment.

[PMID: 31053985 PMCID: PMC6499851 DOI: 10.1186/s40345-019-0146-z] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/21/2018] [Accepted: 03/19/2019] [Indexed: 02/06/2023] Open
Abstract
Background Electroconvulsive therapy (ECT) is an effective treatment for all bipolar states. However, ECT remains underutilized, likely stemming from stigma and the risk of neurocognitive impairment. Neuroimaging research has identified state-specific areas of aberrant brain activity that may serve as targets for therapeutic brain stimulation. Electrode placement determines the geometry of the electric field and can be either non-focal (bitemporal) or more focal (right unilateral or bifrontal). Previous research has shown that electrode placement can impact clinical and cognitive outcomes independent of seizure activity. This review critically examines the evidence that focal (unilateral or bifrontal) electrode placements target specific aberrant circuitry in specific bipolar states to optimize clinical outcomes. We hypothesize that optimal target engagement for a bipolar state will be associated with equivalent efficacy relative to bitemporal non-focal stimulation with less neurocognitive impairment. Methods We performed a literature search in the PubMed database. Inclusion criteria included prospective, longitudinal investigations during the ECT series with specific electrode placements within a bipolar state from 2000 to 2018. Results We identified investigations that met our inclusion criteria with bipolar mania (n = 6), depression (n = 6), mixed (n = 3) and catatonia (n = 1) states. These studies included clinical outcomes and several included cognitive outcomes, which were discussed separately. Conclusions While the heterogeneity of the studies makes comparisons difficult, important patterns included the reduced cognitive side effects, faster rate of response, and equivalent efficacy rates of the focal electrode placements (right unilateral and bifrontal) when compared to non-focal (bitemporal) placement. Further avenues for research include more robust cognitive assessments to separate procedure-related and state-related impairment. In addition, future studies could investigate novel electrode configurations with more specific target engagement for different bipolar states.

Abstract
OBJECTIVE In this systematic review and meta-analysis, the response, remission, and speed of response in adults with major depressive disorder (MDD) and bipolar disorder in depressive episode (BDD) receiving an acute course of electroconvulsive therapy (ECT) were quantitatively analyzed. METHODS Using the Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines, 1660 citations were identified through five electronic databases. Nineteen articles met final inclusion criteria for meta-analysis. RESULTS The pooled response and remission rates with ECT in MDD were 74.2% (n = 1246/1680) and 52.3% (n = 850/1626), respectively. In BDD, they were 77.1% (n = 437/567) and 52.3% (n = 275/377), respectively. Although response rates to ECT were statistically higher in BDD (OR = 0.73, 95% CI: 0.56-0.95, P = 0.02), remission rates were similar (OR = 0.91, 95% CI: 0.65-1.26, P = 0.56). Individuals with BDD vs. MDD required fewer number of ECT sessions to achieve response (SMD = -0.23, 95% CI: -0.44 to -0.023, P = 0.03). There were no significant moderator effects identified. CONCLUSION Response rates and speed of response are higher in individuals with BDD; however, remission rates are equivalent. These findings support increased utilization of ECT in individuals with treatment-refractory BDD.

Abstract
AIMS We reviewed studies that reported speed of antidepressant response to electroconvulsive therapy (ECT) in both bipolar depression (BPD) and major depressive disorder (MDD). METHODS We identified English language reports allowing this comparison. RESULTS Ten studies met our criteria. Four reported significantly faster response in BPD and in one there was trend for faster response. None reported evidence for slower response in BPD. CONCLUSION The findings support further study of speed of response to ECT in BPD.

Abstract
IMPORTANCE Electroconvulsive therapy (ECT) is a highly effective treatment for depression but is infrequently used owing to stigma, uncertainty about indications, adverse effects, and perceived high cost. OBJECTIVE To assess the cost-effectiveness of ECT compared with pharmacotherapy/psychotherapy for treatment-resistant major depressive disorder in the United States. DESIGN, SETTING, AND PARTICIPANTS A decision analytic model integrating data on clinical efficacy, costs, and quality-of-life effects of ECT compared with pharmacotherapy/psychotherapy was used to simulate depression treatment during a 4-year horizon from a US health care sector perspective. Model input data were drawn from multiple meta-analyses, randomized trials, and observational studies of patients with depression. Where possible, data sources were restricted to US-based studies of nonpsychotic major depression. Data were analyzed between June 2017 and January 2018. INTERVENTIONS Six alternative strategies for incorporating ECT into depression treatment (after failure of 0-5 lines of pharmacotherapy/psychotherapy) compared with no ECT. MAIN OUTCOMES AND MEASURES Remission, response, and nonresponse of depression; quality-adjusted life-years; costs in 2013 US dollars; and incremental cost-effectiveness ratios. Strategies with incremental cost-effectiveness ratios of $100 000 per quality-adjusted life-year or less were designated cost-effective. RESULTS Based on the Sequenced Treatment Alternatives to Relieve Depression trial, we simulated a population with a mean (SD) age of 40.7 (13.2) years, and 62.2% women. Over 4 years, ECT was projected to reduce time with uncontrolled depression from 50% of life-years to 33% to 37% of life-years, with greater improvements when ECT is offered earlier. Mean health care costs were increased by $7300 to $12 000, with greater incremental costs when ECT was offered earlier. In the base case, third-line ECT was cost-effective, with an ICER of $54 000 per quality-adjusted life-year. Third-line ECT remained cost-effective in a range of univariate, scenario, and probabilistic sensitivity analyses. Incorporating all input data uncertainty, we estimate a 74% to 78% likelihood that at least 1 of the ECT strategies is cost-effective and a 56% to 58% likelihood that third-line ECT is the optimal strategy. CONCLUSIONS AND RELEVANCE For US patients with treatment-resistant depression, ECT may be an effective and cost-effective treatment option. Although many factors influence the decision to proceed with ECT, these data suggest that, from a health-economic standpoint, ECT should be considered after failure of 2 or more lines of pharmacotherapy/psychotherapy.

Abstract
OBJECTIVE We evaluated the effectiveness of Electroconvulsive Therapy (ECT) in the treatment of Bipolar Disorder (BD) in a large sample of bipolar patients with drug resistant depression, mania, mixed state and catatonic features. METHOD 522 consecutive patients with DSM-IV-TR BD were evaluated prior to and after the ECT course. Responders and nonresponders were compared in subsamples of depressed and mixed patients. Descriptive analyses were reported for patients with mania and with catatonic features. RESULTS Of the original sample only 22 patients were excluded for the occurrence of side effects or consent withdrawal. After the ECT course, 344 (68.8%) patients were considered responders (final CGIi score ≤2) and 156 (31.2%) nonresponders. Response rates were respectively 68.1% for BD depression, 72.9% for mixed state, 75% for mania and 80.8% for catatonic features. Length of current episode and global severity of the illness were the only statistically significant predictors of nonresponse. CONCLUSION ECT resulted to be an effective and safe treatment for all the phases of severe and drug-resistant BD. Positive response was observed in approximately two-thirds of the cases and in 80% of the catatonic patients. The duration of the current episode was the major predictor of nonresponse. The risk of ECT-induced mania is virtually absent and mood destabilization very unlikely. Our results clearly indicate that current algorithms for the treatment of depressive, mixed, manic and catatonic states should be modified and, at least for the most severe patients, ECT should not be considered as a "last resort".

Abstract
BACKGROUND Cyclicity is the essential feature of Bipolar disorder, but the effect of different cycle patterns on the clinical features is poorly understood. Moreover, no studies investigated the relationship between mania and depression inside the manic-depressive cycle. OBJECTIVE The aim of this study is to verify the presence of a relationship between the manic and the depressive phase during the course of bipolar disorder. METHOD 160 consecutive patients with BD type I were recruited and followed for a mean period of 10 years. During the follow-up period, four types of euthymic phases were collected: free intervals present between a depressive and a manic/hypomanic episode (D-M); free intervals present between a manic/hypomanic and a depressive episode (M-D); free intervals present between two depressive episodes (D-D); free intervals present between two manic/hypomanic episodes (M-M). One-way ANOVA using the groups as independent variable and the duration of the free intervals as dependent variables was used. Furthermore, ANOVA was followed by Fisher's Protected Least Significant Difference post-hoc test to measure between-group differences. RESULTS M-D-free interval phases were shorter than D-M-free intervals. M-D intervals were the shortest ones, the D-D and D-M did not differ, and the M-M were the longest. CONCLUSION The strict temporal link between manic and depressive phases supports the idea that the manic-depressive cycle usually begins with a manic episode, and that the subsequent depression is often the consequence of subsiding mania.

Abstract
Background The current paper includes a systematic search of the literature, a detailed presentation of the results, and a grading of treatment options in terms of efficacy and tolerability/safety. Material and Methods The PRISMA method was used in the literature search with the combination of the words 'bipolar,' 'manic,' 'mania,' 'manic depression,' and 'manic depressive' with 'randomized,' and 'algorithms' with 'mania,' 'manic,' 'bipolar,' 'manic-depressive,' or 'manic depression.' Relevant web pages and review articles were also reviewed. Results The current report is based on the analysis of 57 guideline papers and 531 published papers related to RCTs, reviews, posthoc, or meta-analysis papers to March 25, 2016. The specific treatment options for acute mania, mixed episodes, acute bipolar depression, maintenance phase, psychotic and mixed features, anxiety, and rapid cycling were evaluated with regards to efficacy. Existing treatment guidelines were also reviewed. Finally, Tables reflecting efficacy and recommendation levels were created that led to the development of a precise algorithm that still has to prove its feasibility in everyday clinical practice. Conclusions A systematic literature search was conducted on the pharmacological treatment of bipolar disorder to identify all relevant random controlled trials pertaining to all aspects of bipolar disorder and graded the data according to a predetermined method to develop a precise treatment algorithm for management of various phases of bipolar disorder. It is important to note that the some of the recommendations in the treatment algorithm were based on the secondary outcome data from posthoc analyses.

Abstract
BACKGROUND While electroconvulsive therapy (ECT) treatment for depression is highly effective, the high rate of relapse is a critical problem. The current study investigated factors associated with the risk of relapse in mood disorders in patients in which ECT was initially effective. METHOD The records of 100 patients with mood disorders (61 unipolar depression, 39 bipolar depression) who received and responded to an acute ECT course were retrospectively reviewed. Associations between clinical variables and relapse after responding to acute ECT were analyzed. The Ethics Committee of NHO Kure Medical Center approved the study protocol. RESULTS After one year, the percentage of relapse-free patients was 48.7%. There was no significant difference between patients with either unipolar or bipolar depression who were relapse-free (unipolar: 51.1%, bipolar: 45.5%, P=0.603). Valproate maintenance pharmacotherapy in unipolar depression patients was associated with a lower risk of relapse compared to patients without valproate treatment (multivariate analysis, hazard ratio: 0.091; P=0.022). Lithium treatment, reportedly effective for unipolar depression following a course of ECT, tended to lower the risk of relapse (hazard ratio: 0.378; P=0.060). For bipolar depression, no treatment significantly reduced the risk of relapse. LIMITATIONS The current findings were retrospective and based on a limited sample size. CONCLUSIONS The relapse-free rate was similar between unipolar and bipolar depression. Valproate could have potential for unipolar depression patients as a maintenance therapeutic in preventing relapse after ECT.

Abstract
OBJECTIVES Electroconvulsive therapy (ECT) is the most effective treatment for drug-resistant depression (DRD). We estimated the short- and long-term effects of ECT on cognitive functions in patients with unipolar and bipolar DRD. METHODS We investigated 63 patients (18 male, 45 female), aged 34-75 years. Cognitive assessments were performed before, immediately after 6-12 ECT sessions, and 3 months thereafter, using the Benton Visual Retention, Trail Making (TMT), Rey-Osterrieth Complex Figure (ROCF) tests, the Digit Span of the Wechsler Adult Intelligence Scale, and the Rey Auditory Verbal Learning (RAVLT), verbal fluency and Stroop tests. RESULTS Immediately after ECT, a significant worsening was noted in some indices of memory and verbal fluency. However, 3 months after ECT, the indices of both RAVLT and verbal fluency significantly improved compared to baseline, and those of the Benton and ROCF were significantly better than before ECT. The Digit Span, Stroop and TMT were not affected by the treatment. CONCLUSIONS The negative effects of ECT on the reported measures of cognition are transient. After 3 months, the indices of memory were significantly better than before the treatment. In addition to its antidepressant effect in DRD, ECT may also exert a long-term favourable influence on some cognitive functions.

Abstract
OBJECTIVES Brain stimulation techniques are non-pharmacologic strategies which offer additional therapeutic options for treatment-resistant depression (TRD). The purpose of this paper is to review the current literature regarding the use of brain stimulation in resistant bipolar disorder (BD), with particular reference to hypomanic/manic symptoms. METHODS Keywords pertaining to the brain simulation techniques used in the treatment of depression (either unipolar or bipolar) along with their role in regard to hypomanic/manic symptoms were used to conduct an electronic search of the literature. Pertinent findings were identified by the authors and reviewed. RESULTS Brain stimulation techniques represent a valid therapeutic option in TRD. They have been extensively studied in unipolar depression and, to a minor extent, in the depressive phase of BD, showing encouraging but often limited results. With exception of electroconvulsive therapy, the efficacy of brain stimulation in the treatment of manic symptoms of bipolar patients is still uncertain and needs to be fully evaluated. CONCLUSIONS Brain stimulation in BD is derived from its use in unipolar depression. However, there are many important differences between these two disorders and more studies with a systematic approach need to be conducted on larger samples of bipolar patients with treatment-resistant characteristics.

Abstract
INTRODUCTION Electroconvulsive therapy (ECT) is known to be an effective option in the treatment of mood disorders, especially resistant depression. However, the remission achieved by ECT was reported to be not long lasting enough. The aim of the present study was to investigate the relapse/recurrence rates and associated risk factors during the first year after ECT in patients diagnosed with mood disorders. METHODS In a naturalistic observation, patients diagnosed with unipolar depressive disorder or a depressive episode of bipolar disorder and who had achieved remission by ECT were followed up for at least one year. The patients were evaluated with structured interviews during the follow-up period. The relapse/recurrence rates were the primary outcome measurements, while hospitalization and suicide attempts were the secondary outcome measurements. The remitted and non-remitted patients were compared regarding the clinical features, ECT, and pharmacological variables. RESULTS Fifty of 62 patients who had achieved remission with ECT completed the one year follow-up period. Thirty-three patients (66%) had relapse/recurrence, while 17 (34%) patients remained in remission. The relapse rates were similar in patients with unipolar depression and bipolar disorders. The mean number of ECT sessions was higher in relapsed patients with bipolar disorders. Multiple episodes were more frequent in non-remitted patients with unipolar depression. Comorbid psychiatric diagnosis was higher in non-remitted patients with unipolar and bipolar disorders. CONCLUSION The relapse/recurrence rate was found to be fairly high in the first year of follow-up in patients who had achieved remission with ECT. ECT decisions should be made carefully in patients with comorbid psychiatric diagnosis and multiple episodes as these are more risky. The ECT application procedure and successive maintenance treatment (maintenance ECT, pharmacotherapy, and psychotherapy) should be planned to sustain the remission for patients with mood disorders in long-term follow-up.

Abstract
Several lines of evidence have shown the involvement of the glutamatergic system in the function of electroconvulsive therapy (ECT). In particular, patients with treatment resistant depression (TRD) and chronic depression have lower levels of glutamate/glutamine than controls, and ECT can reverse this deficit. Genetic factors might contribute to modulating the mechanisms underlying ECT. This study aimed to evaluate the relationship between three polymorphisms (rs1954787, rs4936554 and rs11218030) of the glutamate receptor ionotropic kainate 4 (GRIK4) gene and responsiveness to ECT treatment in a sample of one hundred individuals, TRD or depressive Bipolar Disorder patients resistant to pharmacological treatments. The results revealed that GRIK4 variants were significantly associated with the response to ECT. In particular, we found that patients carrying the G allele of the GRIK4 rs11218030 had a significantly poorer response to ECT (p=2.71×10(-4)), showing five times the risk of relapse after ECT compared to the AA homozygotes. Analogously, patients carrying the GG rs1954787 genotype and rs4936554A allele carriers presented a double risk of lack of response after ECT (p=0.013 and p=0.040, respectively). In conclusion, the current study provides new evidence, indicating that some GRIK4 variants modulate the response to ECT in patients with depression resistant to treatment, suggesting a role for kainate receptor modulation.

Abstract
This paper reviews recent research on the use of electroconvulsive therapy (ECT) in elderly depressed patients. The PubMed database was searched for literature published within the past 4 years, using the search terms: "electroconvulsive elderly," "electroconvulsive geriatric," "ECT and elderly," and "ECT elderly cognition." The studies in this review indicate excellent efficacy for ECT in geriatric patients. Adverse cognitive effects of ECT in this population are usually transient and not typically severe. In addition, continuation/maintenance ECT (C/M-ECT) may be a favorable strategy for relapse prevention in the elderly after a successful acute course of ECT. ECT is an important treatment option for depressed geriatric patients with severe and/or treatment-resistant illness. New data add to the evidence demonstrating that ECT is a highly effective, safe, and well-tolerated antidepressant treatment option for geriatric patients.

Abstract
The aim of this study was to assess the efficacy and tolerability/acceptability of 6 anesthetic agents in ECT for depressive disorders. We systematically reviewed 14 double-blind randomized controlled trials (610 participants). Efficacy was measured by the mean scores on validated depression scales at 6 ECT (or the nearest score if not available), number of responders at the end of treatment and seizure duration. The acceptability was measured by the proportion of patients who dropped out of the allocated treatment, and the tolerability by the number of serious adverse events and post-treatment cognition assessment. After excluding the trials responsible for heterogeneity, depression scores of patients who were administered methohexital were found to be significantly more improved than those who received propofol (p = 0.001). On the contrary, those who were administered propofol had lower depression scores than those with thiopental at the end of treatment (p = 0.002). Compared to propofol, methohexital was found to be significantly associated with higher seizure duration (p = 0.018). No difference was found for the acceptability profile (all p > 0.05). In summary, ketamine and methohexital may be preferred to propofol or thiopental in regard of effectiveness in depression scores and increased seizure duration. Further studies are warranted to compare ketamine and methohexital.

Abstract
OBJECTIVES To provide guidance for the management of mood disorders, based on scientific evidence supplemented by expert clinical consensus and formulate recommendations to maximise clinical salience and utility. METHODS Articles and information sourced from search engines including PubMed and EMBASE, MEDLINE, PsycINFO and Google Scholar were supplemented by literature known to the mood disorders committee (MDC) (e.g., books, book chapters and government reports) and from published depression and bipolar disorder guidelines. Information was reviewed and discussed by members of the MDC and findings were then formulated into consensus-based recommendations and clinical guidance. The guidelines were subjected to rigorous successive consultation and external review involving: expert and clinical advisors, the public, key stakeholders, professional bodies and specialist groups with interest in mood disorders. RESULTS The Royal Australian and New Zealand College of Psychiatrists clinical practice guidelines for mood disorders (Mood Disorders CPG) provide up-to-date guidance and advice regarding the management of mood disorders that is informed by evidence and clinical experience. The Mood Disorders CPG is intended for clinical use by psychiatrists, psychologists, physicians and others with an interest in mental health care. CONCLUSIONS The Mood Disorder CPG is the first Clinical Practice Guideline to address both depressive and bipolar disorders. It provides up-to-date recommendations and guidance within an evidence-based framework, supplemented by expert clinical consensus.

A systematic review and meta-analysis of randomized controlled trials of adjunctive ketamine in electroconvulsive therapy: efficacy and tolerability. J Psychiatr Res 2015; 62:23-30.

Abstract
BACKGROUND Electroconvulsive therapy (ECT) remains one of the most effective tools in the psychiatric treatment armamentarium, particularly for refractory depression. Yet, there remains a subset of patients who do not respond to ECT or for whom clinically adequate seizures cannot be elicited, for whom ketamine has emerged as a putative augmentation agent. METHODS We searched EMBASE, PsycINFO, CENTRAL, and MEDLINE from 1962 to April 2014 to identify randomized controlled trials evaluating ketamine in ECT (PROSPERO #CRD42014009035). Clinical remission, response, and change in depressive symptom scores were extracted by two independent raters. Adverse events were recorded. Drop-outs were assessed as a proxy for acceptability. Meta-analyses employed a random effects model. RESULTS Data were synthesized from 5 RCTs, representing a total of 182 patients with major depressive episodes (n = 165 Major Depressive Disorder, n = 17 Bipolar Disorder). ECT with ketamine augmentation was not associated with higher rates of clinical remission (Risk Difference (RD) = 0.00; 95%CI = -0.08 to 0.10), response (RD = -0.01; 95%CI = -0.11 to 0.08), or improvements in depressive symptoms (SMD = 0.38; 95%CI = -0.41 to 1.17). Ketamine augmentation was associated with higher rates of confusion/disorientation/prolonged delirium (OR = 6.59, 95%CI: 1.28-33.82, NNH = 3), but not agitation, hypertension or affective switches. CONCLUSION Our meta-analysis of randomized controlled trials of ketamine augmentation in the ECT setting suggests a lack of clinical efficacy, and an increased likelihood of confusion. Individuals for whom adequate seizures or therapeutic response cannot be obtained have not been studied using randomized controlled designs. Additional research is required to address the role of ketamine in this population.

Abstract
BACKGROUND While electroconvulsive therapy (ECT) has been used for many years, there is insufficient research regarding the indications for continuation/maintenance (C/M)-ECT, its safety and efficacy, and the characteristics of patients with schizophrenia or schizoaffective disorder who receive multiple ECT sessions. The aims of this study were to characterize a series of patients who received 30 ECT sessions or more, to describe treatment regimens in actual practice, and to examine the results of C/M-ECT in terms of safety and efficacy, especially the effect on aggression and functioning. METHODS We performed a retrospective chart review of 20 consecutive patients (mean age 64.6 years) with schizophrenia (n=16) or schizoaffective disorder (n=4) who received at least 30 ECT sessions at our ECT unit, and also interviewed the treating physician and filled out the Clinical Global Impression-Severity, Global Assessment of Functioning, and the Staff Observation Aggression Scale-Revised. RESULTS Patients received a mean of 91.3 ECT sessions at a mean interval of 2.6 weeks. All had been hospitalized for most or all of the previous 3 years. There were no major adverse effects, and cognitive side effects were relatively minimal (cognitive deficit present for several hours after treatment). We found that ECT significantly reduced scores on the Staff Observation Aggression Scale-Revised subscales for verbal aggression and self-harm, and improved Global Assessment of Functioning scores. There were reductions in total aggression scores, subscale scores for harm to objects and to others, and Clinical Global Impression-Severity scores, these were not statistically significant. CONCLUSION C/M-ECT is safe and effective for chronically hospitalized patients. It improves general functioning and reduces verbal aggression and self-harm. More research using other aggression tools is needed to determine its effects and to reproduce our findings in prospective and controlled studies.

Unipolar depressed patients were treated with bilateral ECT, and on remission were randomly assigned to a fixed schedule continuation ECT or to combined lithium and nortriptyline for 6 months. A second study compared three electrode placements in unipolar and bipolar depressed patients. METHOD Nineteen published reports were reviewed. The findings are compared with those of a parallel multi-hospital study of ECT led by a Columbia University Collaboration (CUC) team that studied right unilateral ECT in a similar population with similar inclusion/exclusion and remission criteria. Successful ECT was followed by placebo, nortriptyline alone, or combined lithium, and nortriptyline. RESULTS Relapse rates after remission were similar with fixed schedule ECT as with medications. Predictors of outcome (psychosis, suicide risk, polarity, melancholia, atypical depression, age) and technical aspects (electrode placement, seizure threshold, speed of response) are discussed, CONCLUSION The findings offer criteria to optimize the selection of patients, the technique, and outcome of ECT for unipolar and bipolar depressed patients. Continuation ECT is an effective alternative to continuation treatment with lithium and nortriptyline. Bilateral electrode placement is more efficient than alternative placements. ECT relieves both bipolar and unipolar depression.

Abstract
BACKGROUND It has been debated as to whether the polarity of mood disorder (bipolar versus unipolar) has prognostic significance for electroconvulsive therapy (ECT) outcome. In the treatment guidelines, ECT is recommended more readily for unipolar depression and not so for bipolar depression. This study aims to examine efficacy of bipolar and unipolar depression to ECT in a real life naturalistic setting. METHOD We studied the ECT parameters of all consecutive patients with a diagnosis of unipolar depression (recurrent depressive disorder, ≥2 episodes of depression) and bipolar depression referred for ECT between the months of July 2008 and December 2010 (BP-D: n=44) and (UP-D: n=106). RESULTS When bipolar depression was compared to unipolar depression, the average motor seizure duration (mean=46.9 and 46.7, t=-0.06, p=0.94), number of ECTs required for improvement (mean=6.4 and 6.5, t=0.17, p=0.86), duration of inpatient stay after ECT initiation in days (mean=16.2 and 16.6, t=0.23, p=0.81) and improvement as assessed using a Likert scale (Mann-Whitney U, Z=-0.09, p=0.92) were not statistically different between the groups. CONCLUSIONS We did not find any difference in efficacy of ECT between the two forms of depression in real life setting. This calls for justification of use of ECT in all patients with depression irrespective of the type of illness polarity and inclusion of ECT as a routine treatment option in bipolar depression guidelines.

Abstract
Cognitive side-effects from electroconvulsive therapy (ECT) can be distressing for patients and early detection may have an important role in guiding treatment decisions over the ECT course. This prospective study examined the utility of an early cognitive screening battery for predicting cognitive side-effects which develop later in the ECT course. The screening battery, together with the Mini Mental Status Examination (MMSE), was administered to 123 patients at baseline and after 3 ECT treatments. A more detailed cognitive battery was administered at baseline, after six treatments (post ECT 6) and after the last ECT treatment (post treatment) to assess cognitive side-effects across several domains: global cognition, anterograde memory, executive function, speed and concentration, and retrograde memory. Multivariate analyses examined the predictive utility of change on items from the screening battery for later cognitive changes at post ECT 6 and post treatment. Results showed that changes on a combination of items from the screening battery were predictive of later cognitive changes at post treatment, particularly for anterograde memory (p < 0.01), after controlling for patient and treatment factors. Change on the MMSE predicted cognitive changes at post ECT 6 but not at post treatment. A scoring method for the new screening battery was tested for discriminative ability in a sub-sample of patients. This study provides preliminary evidence that a simple and easy-to-administer measure may potentially be used to help guide clinical treatment decisions to optimise efficacy and cognitive outcomes. Further development of this measure and validation in a more representative ECT clinical population is required.

Abstract
OBJECTIVE Whether responses to antidepressants differ in bipolar and unipolar depression remains unresolved. METHOD We analyzed patient characteristics and outcomes of antidepressant treatment of 1036 depressed patients with bipolar-I or bipolar-II disorder, or unipolar major depression, using bivariate and multivariate methods and survival analysis, testing the hypothesis that responses would be superior in unipolar depression. RESULTS Antidepressants were given to 84.8% (878/1036) of depressed patients: 58.9% of 93 bipolar-I, 80.1% of 117 bipolar-II, and 91.3% of 668 unipolar disorder cases. The 158 not given antidepressants had more manias/year, spent more months in mania and depression, and were far more likely to receive mood stabilizers or antipsychotics long term. Improvement of HDRS21 depression ratings ranked: bipolar-II (69.6%) > bipolar-I (62.9%) > unipolar (57.9%; P < 0.0001), independent of initial illness severity. Responder rates (≥50% improved without switching) ranked: bipolar-II (77.0%) > bipolar-I (71.6%) > unipolar (61.7%; P < 0.0001). Remission rates (final HDRS < 7) ranked: 54.0%, 50.6%, and 40.8% respectively (P = 0.02); 67.5% remitted within 12 weeks of treatment. Survival-computed median time to remission (15.0 weeks, overall) was shortest for bipolar-II patients (10.7 weeks). The 3-month risk of switching into mania-hypomania ranked: bipolar-II (15.8%) > bipolar-I (8.60%) > unipolar (0.56%). Multivariate modeling found bipolar diagnosis, shorter latency to remission, more recent trial year, and fewer weeks depressed before treatment to be associated with greater percent improvement of HDRS ratings. CONCLUSION Selective use of antidepressants with or without mood stabilizers in non-agitated, depressed bipolar disorder patients for short periods was effective with moderate risk of potentially dangerous, manic mood elevation.

Abstract
OBJECTIVE Electroconvulsive therapy (ECT) is an effective mode of treatment--especially for severe depression and for depression refractory to pharmacotherapy, nevertheless the mode of action of ECT is far from being fully understood. This study assessed the effects of a series of ECT in depressive subjects on cerebral glucose metabolism measured by FDG-PET scans pre- and post-therapy in thus far the largest group of 12 patients. METHODS Our analysis included careful repeated evaluation of clinical changes in mood and behaviour by standardised questionnaires, which allowed testing for a potential correlation between clinical and cerebral metabolic changes. PET scanning was done within a predefined time window and we used predefined ROIs with counts normalized to the pons activity. RESULTS We observed few changes in cerebral glucose metabolism over time. There was a marginal increase in the left temporal and a trend for a decrease in left frontobasal areas subsequent to treatment in our sample. FDG uptake patterns remained remarkably stable in all the other predefined ROIs pre- and post-treatment. There were no significant correlations between changes in relative metabolic rates and changes in depression scores and parameters derived from neurocognitive testing. CONCLUSIONS Our study thus cannot support the view that FDG-PET can assess the functional brain changes that are likely to occur subsequent to ECT in such a scenario, but this may be related to limited sensitivity given the sample size. Future studies thus might wish to challenge this notion in larger patient samples to clarify this issue.

Abstract
The Canadian Network for Mood and Anxiety Treatments published guidelines for the management of bipolar disorder in 2005, with updates in 2007 and 2009. This third update, in conjunction with the International Society for Bipolar Disorders, reviews new evidence and is designed to be used in conjunction with the previous publications.The recommendations for the management of acute mania remain largely unchanged. Lithium, valproate, and several atypical antipsychotic agents continue to be first-line treatments for acute mania. Monotherapy with asenapine, paliperidone extended release (ER), and divalproex ER, as well as adjunctive asenapine, have been added as first-line options.For the management of bipolar depression, lithium, lamotrigine, and quetiapine monotherapy, as well as olanzapine plus selective serotonin reuptake inhibitor (SSRI), and lithium or divalproex plus SSRI/bupropion remain first-line options. Lurasidone monotherapy and the combination of lurasidone or lamotrigine plus lithium or divalproex have been added as a second-line options. Ziprasidone alone or as adjunctive therapy, and adjunctive levetiracetam have been added as not-recommended options for the treatment of bipolar depression. Lithium, lamotrigine, valproate, olanzapine, quetiapine, aripiprazole, risperidone long-acting injection, and adjunctive ziprasidone continue to be first-line options for maintenance treatment of bipolar disorder. Asenapine alone or as adjunctive therapy have been added as third-line options.

Abstract
OBJECTIVES Treatment resistance in bipolar depression is a common clinical problem that constitutes a major challenge for the treating clinician as there is a paucity of treatment options. The objective of this paper was to review the evidence for treatment options in treatment-resistant bipolar depression, as found in randomized controlled trials and with special attention to the definition and assessment of treatment resistance. METHODS A Medline search (from database inception to May 2012) was performed using the search terms treatment resistance or treatment refractory, and bipolar depression or bipolar disorder, supplemented with 43 separate searches using the various pharmacologic agents or technical interventions as search terms. RESULTS Only seven studies met our inclusion criteria. These studies examined the effects of ketamine (n = 1), (ar)modafinil (n = 2), pramipexole (n = 1), lamotrigine (n = 1), inositol (n = 1), risperidone (n = 1), and electroconvulsive therapy (ECT) (n = 2). CONCLUSIONS The available level I evidence for treatment strategies in resistant bipolar depression is extremely scarce, and although the response rates reported are reassuring, most of the strategies remain experimental. There is an urgent need for further study in homogeneous patient samples using a clear concept of treatment resistance.

Abstract
BACKGROUND Few studies have compared response to electroconvulsive therapy (ECT) in depressed patients with unipolar and bipolar disorder. METHODS We reviewed the charts of inpatients with unipolar or bipolar depression who received open treatment with right unilateral ECT. We compared the number of treatments, demographics, and change in Global Assessment of Functioning scores and length of hospital stay in both groups. RESULTS Whereas changes in Global Assessment of Functioning scores and length of stay overlapped, the number of treatments in patients with bipolar disorder (mean ± SD, 7.5 ± 1.6) was lower than that in patients with unipolar disorder (mean ± SD, 10.2 ± 1.9). CONCLUSION Fewer ECT treatments may be required to achieve similar benefit in patients with bipolar disorder compared to patients with unipolar disorder.

Abstract
The current statement is a systematic review of the available data concerning the efficacy of medication treatment of bipolar disorder (BP). A systematic MEDLINE search was made concerning the treatment of BP (RCTs) with the names of treatment options as keywords. The search was updated on 10 March 2012. The literature suggests that lithium, first and second generation antipsychotics and valproate and carbamazepine are efficacious in the treatment of acute mania. Quetiapine and the olanzapine-fluoxetine combination are also efficacious for treating bipolar depression. Antidepressants should only be used in combination with an antimanic agent, because they can induce switching to mania/hypomania/mixed states/rapid cycling when utilized as monotherapy. Lithium, olanzapine, quetiapine and aripiprazole are efficacious during the maintenance phase. Lamotrigine is efficacious in the prevention of depression, and it remains to be clarified whether it is also efficacious for mania. There is some evidence on the efficacy of psychosocial interventions as an adjunctive treatment to medication. Electroconvulsive therapy is an option for refractory patients. In acute manic patients who are partial responders to lithium/valproate/carbamazepine, adding an antipsychotic is a reasonable choice. The combination with best data in acute bipolar depression is lithium plus lamotrigine. Patients stabilized on combination treatment might do worse if shifted to monotherapy during maintenance, and patients could benefit with add-on treatment with olanzapine, valproate, an antidepressant, or lamotrigine, depending on the index acute phase. A variety of treatment options for BP are available today, but still unmet needs are huge. Combination therapy may improve the treatment outcome but it also carries more side-effect burden. Further research is necessary as well as the development of better guidelines and algorithms for the step-by-step rational treatment.

Abstract
OBJECTIVE Bipolar major depression differs considerably from unipolar major depression with regard to the efficacy of treatment with antidepressants. In bipolar depression, response to treatment with antidepressants is disappointing. Whether response to electroconvulsive therapy (ECT) differs between bipolar and unipolar depression remains unclear. Therefore, this systematic review investigates the relative efficacy of ECT in both forms of depression. METHODS Relevant cohort studies were identified from a systematic search of the PubMed electronic database. Six studies were included in this meta-analysis. RESULTS In this meta-analysis, the overall remission rate was 50.9% (n = 402/790) for patients with unipolar depression and 53.2% (n = 168/316) for patients with bipolar major depression. A pooled odds ratio (OR) and confidence interval (CI) were calculated using random-effects meta-analysis with the Mantel-Haenzel method. This analysis shows similar efficacy of ECT in patients with unipolar and bipolar depression (OR = 1.08, 95% CI: 0.75-1.57). CONCLUSION ECT appears to be equally effective for both bipolar and unipolar depression and the remission rates are encouraging, especially for bipolar depression.

Abstract
Electroconvulsive therapy (ECT) has been used clinically since 1938. Its most common use is in the treatment of depression: first line treatment where rapid recovery is a priority, but more frequently as an effective treatment for patients who do not respond to pharmacological and psychological approaches. Whilst it is widely hailed as an effective treatment, concerns about its effect on cognition remain. The development of magnetic seizure therapy (MST) over the past decade has attempted to devise a therapy with comparable efficacy to ECT, but without the associated cognitive side effects. The rationale for this is that MST uses magnetic fields to induce seizures in the cortex, without electrical stimulation of brain structures involved with memory. MST has been used successfully in the treatment of depression, yet there is a dearth of literature in comparison with ECT. We present a systematic review of the literature on ECT (from 2009-2011) and MST (from 2001-2011).

Abstract
BACKGROUND Despite pharmacological advances, bipolar disorder continues to be difficult to treat. This article reviews the evidence base for the use of electroconvulsive therapy (ECT) and other brain stimulation therapies in bipolar disorder. METHODS The evidence base for the efficacy of ECT and transcranial magnetic stimulation in the treatment of mania, bipolar depression and mixed affective states was reviewed. Reports on the use of vagus nerve stimulation, stereotaxic surgery, deep brain stimulation, magnetic seizure therapy and transcranial direct current stimulation in treating depression, as well as bipolar disorder were also reviewed. Studies were identified from Medline and Embase database searches. RESULTS There are a few randomized controlled trials of ECT in mania and bipolar depression, and none in mixed affective states. Nevertheless, such studies consistently reported clinically meaningful efficacy, with a majority of pharmacotherapy resistant patients responding to ECT. Evidence for the use of other brain stimulation therapies in treating bipolar mood states is preliminary and limited. CONCLUSIONS ECT is an effective treatment for acute mania, bipolar depression and mixed affective states and has useful efficacy even in pharmacotherapy-resistant patients. Other brain stimulation techniques may have potential for the treatment of bipolar disorder and should be further researched.

Abstract
Major depression is a common mental health problem and associated with significant morbidity and mortality, including impaired social and physical functioning and increased risk for suicide. Electroconvulsive therapy (ECT) is highly efficacious in treatment-resistant depressive disorders, but cognitive side effects are frequently associated with the treatment. Magnetic seizure therapy (MST) is a form of convulsive therapy, using magnetic fields in order to induce therapeutic seizures. First studies suggested that cognitive side effects of MST, including postictal recovery time, are more benign than those resulting from ECT treatment. In this open-label study we tested the hypothesis that MST is associated with clinically significant antidepressant effects in treatment-resistant depression (TRD) as an add-on therapy to a controlled pharmacotherapy. Twenty patients suffering from TRD were randomly assigned to receive either MST or ECT starting from July 2006 until November 2008. Primary outcome measure was antidepressant response assessed by Montgomery Åsberg Depression Scale. Secondary outcome measures included Hamilton Depression Rating Scale, Hamilton Anxiety Scale, Beck Depression Inventory and 90-Item Symptom Checklist. Antidepressant response (improvement of 50% in MADRS ratings) was statistically significant and of similar size in both treatment groups. Cognitive side effects were observed in neither group. Characteristics in MST- and ECT-induced seizures were comparable, especially regarding ictal activity and postictal suppression. Thus, MST may be a potential alternative to ECT if efficacy and safety are validated in larger clinical trials.

Abstract
BACKGROUND Recent trials have demonstrated clinically meaningful efficacy and minimal cognitive side effects with ultrabrief pulsewidth right unilateral (RUL) ECT. In many countries it is gradually being adopted into clinical practice and further information on predictors of response is needed. METHODS Data collected from 75 depressed patients who received ultrabrief RUL ECT in a prospective research trial were analysed for predictors of response. Mood improvement was assessed with the Montgomery-Asberg Depression Rating Scale. Improvement in unipolar versus bipolar depression was analysed. RESULTS Sixty-one percent of patients met the criteria for response and 36% met the criteria for remission. Logistic regression identified index episode duration ≥one year (OR=10.50, p=.006), fewer failed antidepressant treatments (OR=0.46, p=.003), previous ECT course (OR=7.33, p=.01), and absence of concurrent antidepressant (OR=0.09, p=.005) as predictors of response. Psychotic features (OR=7.18, p=.032) and baseline depression severity (OR=0.90, p=.017) were predictors of remission. There was a trend towards greater improvement in bipolar than unipolar depression in the first week of treatment (p=0.077). LIMITATIONS Data were obtained from a prospective but non-randomised clinical trial which was designed to evaluate efficacy rather than to examine predictors of response. Treatment decisions (concurrent medication, switching to other types of ECT) were made on clinical grounds. CONCLUSIONS This preliminary study suggests that predictors of response for ultrabrief RUL ECT are similar to those identified for other types of ECT previously studied.

Abstract
OBJECTIVES This study aimed to ascertain predictors of nonresponse to electroconvulsive therapy (ECT) in a large sample of major depressive patients resistant to pharmacologic treatment. METHODS A total of 208 depressive patients (31 with major depression [UP], 101 with bipolar disorder II [BP II], and 76 with bipolar disorder I [BP I] according to DSM-IV criteria) were included in the study and treated with bilateral ECT on a twice-a-week schedule. The patients were assessed before (baseline) and a week after the ECT course (final score) using the Hamilton Rating Scale for Depression-17 items (HAM-D-17), the Young Mania Rating Scale (YMRS), the Brief Psychiatric Rating Scale (BPRS), and the Clinical Global Improvement (CGI). Responders were defined as those patients with a reduction of at least 50% in HAM-D-17 score and a rating of 2 ("much improved") or 1 ("very much improved") in the CGI-Improvement subscale. RESULTS At the end of the ECT course, 152 patients (64%) were classified as responders and 56 patients (36%) were classified as nonresponders. On backward stepwise logistic regression, bipolar subtype (odds ratio [OR]=17.85; 95% confidence level [CL]=1.786-178.407), higher mean baseline YMRS scores (OR=1.094; 95% CL=1.025-1.166), lower mean baseline HAM-D-17 scores (OR=0.928; 95% CL=0.860-1.002), and length of current episode (OR=1.047; 95% CL=1.009-1.086) were identified as statistically significant predictors of nonresponse. CONCLUSIONS ECT was an effective treatment for approximately two-thirds of the patients with medication-resistant depression who were included in this study. ECT nonresponse was associated with bipolar subtype, presence of manic symptoms during depression, slightly less severe depressive symptomatology, and protracted duration of the episode.
