Abstract
BACKGROUND Immune dysfunction and inflammation participate in the pathophysiology of bipolar disorder (BD). Abnormal levels of inflammatory markers, namely, red cell distribution width (RDW) and platelet distribution width (PDW), were detected in BD. Electroconvulsive therapy (ECT) for various mental disorders including BD was linked to changes in these inflammatory mediators. Hence, we aimed to assess the impact of ECT on PDW and RDW in patients with BD. METHODS Seventy-two patients aged ≥ 16 were enrolled in the current prospective cohort study over 6 months, diagnosed as BD based on DSM-IV and indicated for ECT and complete blood count (CBC) drawn pre-ECT and after four ECT sessions. RESULTS By the end of the ECT sessions, we noticed a significant elevation in PDW with lowering in RDW levels. However, no significant differences were detected before and after ECT regarding platelet (PLTs) count, mean platelet volume (MPV), and Plateletcrit (PCT). CONCLUSION ECT seems to improve the CBC-derived inflammatory markers (RDW and PDW) subsequently, improving the underlying inflammatory process in BD without disturbing PLT homeostasis which support its anti-inflammatory role in BD.

Abstract
Major depressive disorder (MDD) remains a significant global health concern, with limited and slow efficacy of existing antidepressants. Electroconvulsive therapy (ECT) has superior and immediate efficacy for MDD, but its action mechanism remains elusive. Therefore, the elucidation of the action mechanism of ECT is expected to lead to the development of novel antidepressants with superior and immediate efficacy. Recent studies suggest a potential role of hippocampal astrocyte in MDD and ECT. Hence, we investigated antidepressant effect of electroconvulsive stimulation (ECS), an animal model of ECT, -related genes in hippocampal astrocyte with a mouse model of MDD, in which corticosterone (CORT)-induced depression-like behaviors were recovered by ECS. In this model, both of CORT-induced depression-like behaviors and the reduction of hippocampal astrocyte were recovered by ECS. Following it, astrocytes were isolated from the hippocampus of this model and RNA-seq was performed with these isolated astrocytes. Interestingly, gene expression patterns altered by CORT were reversed by ECS. Additionally, cell proliferation-related signaling pathways were inhibited by CORT and recovered by ECS. Finally, serum and glucocorticoid kinase-1 (SGK1), a multi-functional protein kinase, was identified as a candidate gene reciprocally regulated by CORT and ECS in hippocampal astrocyte. Our findings suggest a potential role of SGK1 in the antidepressant effect of ECS via the regulation of the proliferation of astrocyte and provide new insights into the involvement of hippocampal astrocyte in MDD and ECT. Targeting SGK1 may offer a novel approach to the development of new antidepressants which can replicate superior and immediate efficacy of ECT.

Abstract
OBJECTIVE The objective of this study was to evaluate the online component of a blended curriculum for psychiatry residents on the use of electroconvulsive therapy (ECT) to treat depression in older adults. METHODS Second- and third-year general psychiatry residents completed a blended learning curriculum during their core geriatric psychiatry rotation. The curriculum consisted of didactic seminars, hands-on clinical management, and two online clinical cases focused on the management of late-life depression with ECT. Knowledge acquisition following module completion was measured using a nine-question multiple-choice test. The authors adapted the Medical E-Learning Evaluation Survey (MEES) to measure resident satisfaction, clinical relevance, and instructional design. RESULTS A total of 37 residents completed both online modules. Of these, 35 residents completed the knowledge test and 23 completed the adapted MEES. Almost all participants (96%) agreed or strongly agreed that the modules were relevant to their clinical work, evidence-based, able to be completed in a reasonable amount of time, and a valuable learning experience. The average score on the knowledge test, after removing one outlier, was 83%. CONCLUSION Psychiatry residents are very satisfied with the content and delivery of the online component of a blended curriculum for understanding the use of ECT for late-life depression. Future work should examine satisfaction with the remainder of the curricula as well as the impact on longer-term knowledge acquisition and patient care.

Abstract
Schizophrenia is a devastating psychiatric disorder that has detrimental effects on a significant portion of the global population. Electroconvulsive therapy (ECT), as a safe and effective physical therapy for schizophrenia, has demonstrated the ability to rapidly improve both positive and negative symptoms. Despite being used to treat schizophrenia for over 80 years, the therapeutic mechanisms of ECT are still in the early stages of exploration. Evidence has suggested that immune inflammation contributes to the pathogenesis of schizophrenia by interacting with neurotransmitters, neurodevelopment, and neurodegeneration. Given the importance of ECT as a fast-acting physical therapy for schizophrenia, gaining a deeper understanding of the role of immune inflammation may lead to developing innovative therapeutic approaches. This review summarized existing research that examined changes in peripheral inflammation following ECT in schizophrenia patients, and the effects of electroconvulsive stimulation (ECS) on neuroinflammation in animal studies.

Abstract
BACKGROUND Schizophrenia is a kind of intractable brain disorder. Electroconvulsive therapy (ECT) has been used to rapidly improve the clinical symptoms of patients with schizophrenia, but the effect of ECT on topological attributes of brain functional network in patients with schizophrenia has not been clear. The purpose of this study was to investigate the brain functional network mechanism of ECT against schizophrenia. METHODS Thirty-one patients with schizophrenia and fifty healthy controls matching age, gender, and years of education were included. All participants underwent general data collection and magnetic resonance imaging scanning before ECT, and clinical symptoms were assessed using the Positive And Negative Syndrome Scale (PANSS). MRI and clinical symptoms were collected again after the first and eighth ECT application. The functional brain network was constructed on the basis of magnetic resonance imaging, and the global and node topological properties were analyzed. Repeated measure variance analysis was used to explore the changes of the topological attribute values and clinical symptom scores before and after ECT, and Bonferroni post hoc analysis was performed. The independent sample t-test was used to compare the differences in the topological attribute values between patients and healthy controls at three time points before and after ECT. Partial correlation analysis was performed for topological attribute values and clinical symptom scores of abnormal brain regions in the patient groups and their changes during ECT. A general linear regression model was used to predict the outcome after the final eighth ECT using the patient's response to the first ECT. RESULTS (1) One ECT can restore the gamma(γ), lamuda(λ), sigma(σ), nodal global efficiency (Ne) of right insular gyrus ventral agranular insula (INS_R_vIa) and nodal local efficiency (NLe) of bilateral fusiform gyrus medioventral area37 (FuG_A37mv). Eight ECT can also restore the NLe of cortex rostral lingual gyrus (MVOcC _R_rLinG). Eight ECT did not improve the Ne of right superior parietal lobule rostral area 7 (SPL_R_A7r) and NLe of left superior frontal gyrus medial area 6 (SFG_L_A6m). (2) Even after only the first use of ECT, total PANSS scores began to decrease (mean ΔPANSSECT1 was 11.7%; Range, 2%-32.8%), decreased significantly after the eighth application (mean ΔPANSSECT8 was 86.0%; Range,72.5% to 97.9%). Five patients met the response criteria after ECT1 (20% reduction in PANSS total score), and all patients met the response criteria after ECT8. (3) Linear regression analysis showed that ΔPANSSECT1 was a significant predictor of ΔPANSSECT8 (F=5.387, P=0.028), and ΔPANSSECT1 explained 15.7% of the variance of ΔPANSSECT8 (R2=0.157). CONCLUSIONS ECT was able to normalize γ, λ, σ, Ne of INS_R_vIa, NLe of bilateral FuG_A37mv in SZ patients after the first treatment, and NLe of MVOcC_R_rLinG after the eighth ECT. ECT significantly alleviates psychotic symptoms in patients with SZ, and its efficacy after eight sessions can be predicted by the patient's response to the first session of ECT.

Abstract
Electroconvulsive therapy (ECT) is an efficient therapeutic resource for psycho-pharmacotherapeutic resistant forms of depression. ECT is a form of electrical brain stimulation involving the induction of a controlled seizure, clinically similar to an epileptic seizure, that is initiated in the prefrontal region of the brain and spreads to the cortex and subcortex, including the diencephalic structures. This is achieved by creating a transcranial electric field and synchronously depolarizing neuronal membranes. The mechanisms of action of ECT are not yet fully understood, but several hypotheses have been proposed to explain how it affects the brain: neurotransmitter changes, neuroplasticity, network connectivity, endocrine system regulation and changes in regional cerebral blood flow and regional metabolism.

Abstract
BACKGROUND The neurogenesis hypothesis is a promising candidate etiologic hypothesis for depression, and it is associated with electroconvulsive therapy (ECT). However, human in vivo molecular-level evidence is lacking. OBJECTIVE We used neuron-derived extracellular vesicles (NDEVs) as a "window to the neurons" to explore the in vivo neurogenesis status associated with ECT in patients with treatment-resistant depression (TRD). METHODS In this study, we enrolled 40 patients with TRD and 35 healthy controls (HCs). We isolated NDEVs from the plasma of each participant to test the levels of doublecortin (DCX), a marker of neurogenesis, and cluster of differentiation (CD) 81, a marker of EVs. We also assessed the plasma levels of brain-derived neurotrophic factor (BDNF), a protein that is known to be associated with ECT and neuroplastic processes. RESULTS Our findings indicated that both the levels of DCX in NDEVs and BDNF in plasma were significantly lower in TRD patients compared to HCs at baseline, but increased following ECTs. Conversely, levels of CD81 in NDEVs were found higher in TRD patients at baseline, but did not change after the ECT treatments. Exploratory analyses revealed that lower levels of BDNF in plasma and DCX in NDEVs, along with higher CD81 levels in NDEVs, were associated with more severe depressive symptoms and reduced cognitive function at baseline. Furthermore, higher baseline CD81 concentrations in NDEVs were correlated with greater decreases in depression symptoms. CONCLUSIONS We first present human in vivo evidence of early neurogenesis using DCX through NDEVs: decreased in TRD patients, increased after ECTs.

Abstract
Electroconvulsive therapy (ECT) is a safe and effective treatment for catatonia with high response rates. Although empirical data suggest that tolerability and efficacy are at least as good as in adults, ECT treatment of children, adolescents, and geriatric patients seems to pose a specific challenge for many practitioners. This article intends to explore and discuss reasons hindering the use of ECT in these patient groups, give an overview on the use of ECT to treat catatonia and provide practical advice on ECT in children, adolescents, and geriatric patients for the treatment of catatonia. Classification of catatonia as a subform of schizophrenia and a diagnostic overlap with other common conditions in children, adolescents, and geriatric patients might lead to underdiagnosis of catatonia. Concerns about the mechanism of action and about a lack of controlled studies as well as general concerns about the use of ECT in children and adolescents might lead to underutilization of ECT. However, studies of ECT to treat catatonia in children, adolescents, and geriatric patients consistently show its safety and effectiveness. Administration of ECT needs to consider some specific characteristics of children, adolescents, and geriatric patients. In conclusion, ECT is a safe and highly effective treatment for catatonia across the lifespan. Existing evidence does not warrant restrictions of its use in certain age groups.

Abstract
Depressive rumination has been implicated in the onset, duration, and treatment response of refractory depression. Electroconvulsive therapy (ECT) is remarkably effective in treatment of refractory depression by modulating the functional coordination between brain hubs. However, the mechanisms by which ECT regulates depressive rumination remain unsolved. We investigated degree centrality (DC) in 32 pre- and post-ECT depression patients as well as 38 matched healthy controls. An identified brain region was defined as the seed to calculate functional connectivity (FC) in whole brains. Rumination was measured by the Ruminative Response Scale (RRS) and its relationships with identified DC and FC alterations were examined. We found a significant negative correlation between DC of the right orbitofrontal cortex (rOFC) before ECT and brooding level before and after treatment. Moreover, rOFC DC increased after ECT. DC of the left superior temporal gyrus (lSTG) was positively correlated with reflective level before intervention, while lSTG DC decreased after ECT. Patients showed elevated FC in the rOFC with default mode network. No significant association was found between decreased RRS scores and changes in DC and FC. Our findings suggest that functional changes in rOFC and lSTG may be associated with the beneficial effects of ECT on depressive rumination.

Abstract
OBJECTIVE We aim to describe use of electroconvulsive therapy (ECT) to treat super refractory status epilepticus (SRSE) in pregnancy and review the literature regarding utility and safety of ECT in refractory status epilepticus. BACKGROUND Status epilepticus (SE) is a commonly encountered emergency in neuro-critical care world. Pharmacotherapy of status epilepticus in pregnancy is very challenging given the effect of the majority of antiepileptic drugs (AEDs) on fetal development. Although there has been growing evidence for use of ECT in status epilepticus, data about its utility in pregnancy is lacking. DESIGN/METHOD A twenty-one year old Caucasian female with history of epilepsy presented at 8 weeks of gestation as status epilepticus (SE) after abrupt discontinuation of her AEDs. Treatment was initiated with standard regimen of benzodiazepine and levetiracetam, which was progressively expanded to include approximately 10 anti-epileptic drugs over the course of 30 days. The status epilepticus was super refractory to sedation. She underwent ECT on day 31 with remarkable improvement in electroencephalogram (EEG) pattern and resolution of status epilepticus following a single ECT session. We reviewed PubMed and collated case reports involving the use of ECT in status epilepticus with emphasis on differences in various confounding factors esp. etiology of status and age group. CONCLUSION Our case is the first reported case of ECT for successful treatment of SRSE in pregnancy. While majority AEDs pose a significant maternal and fetal risk during pregnancy, ECT could be a potential frontline therapy for SE in pregnancy.

Abstract
Electroconvulsive therapy (ECT) is an effective and safe medical treatment for patients with severe mood and neuropsychiatric disorders. Since the advent of ECT, extensive research has been performed to identify the predictive factors for response to ECT. In recent decades, postictal suppression on an electroencephalogram (EEG) has been considered a potential predictor of response to ECT. We aimed to investigate the direct association between postictal suppression and the therapeutic effects of ECT. In this systematic review, all articles in the field of the association between postictal suppression and the therapeutic effects of ECT published between 1990 and 2021 were identified. The full texts of these articles, which include clinical trials and retrospective and cross-sectional studies, are available in scholarly research databases and search engines, including PubMed, Google Scholar, OVID, Web of Science, and Scopus. Of all retrieved articles, eight studies, including four retrospective cohort articles and four clinical trials, met the inclusion criteria for further analyses. The findings of this study showed a significant association between postictal suppression and the therapeutic efficacy of ECT. Factors such as electrode placement, tachycardia, type of anesthetic agent, and EEG amplitude were also directly related to postictal suppression and the efficacy of ECT. Postictal suppression on EEG can be considered a predictor of response to ECT. To increase the effectiveness of treatment with ECT and increase postictal suppression, factors including electrode placement, tachycardia, type of anesthesia, and EEG amplitude should be considered, which highlights the need for further research.

Abstract
OBJECTIVES The efficacy of electroconvulsive therapy (ECT) in treating mood disorders (MDs) is hypothesized to be mediated by the induction of neurotrophic factors (denoted "angioneurins") that trigger neuronal plasticity. This study aimed to assess the effects of ECT on serum angioneurin levels in patients with MD. METHODS A total of 110 patients with MDs including 30 with unipolar depression, 25 with bipolar depression (BD), 55 with bipolar mania (BM), and 50 healthy controls were included in the study. Patients were subdivided into two groups: those who received ECT + medication (12 ECT sessions) and those who received only medication (no-ECT). Depressive and manic symptom assessments and measurements of vascular endothelial growth factor (VEGF), fibroblast growth factor-2, nerve growth factor (NGF), and insulin-like growth factor-1 levels in blood samples were performed at baseline and week 8. RESULTS Patients in the ECT group, specifically those with BD and BM, had significantly increased levels of VEGF compared to their baseline VEGF levels (p = 0.002). No significant changes in angioneurin levels were observed in the no-ECT group. Serum NGF levels were significantly associated with a reduction in depressive symptoms. Angioneurin levels were not associated with manic symptom reduction. CONCLUSIONS This study hints that ECT may increase VEGF levels with angiogenic mechanisms that amplify NGF signaling to promote neurogenesis. It may also contribute to changes in brain function and emotional regulation. However, further animal experiments and clinical validation are needed.

Abstract
Electroconvulsive Therapy (ECT) is an effective treatment for mood and psychotic disorders but there is growing evidence of treatment resistant to ECT. Our study aimed to investigate the relationship between the number of previous illness episodes and the symptomatic improvement after acute ECT treatment. We conducted a retrospective naturalistic cohort analysis of patients' ECT registry data from March 2017 to February 2023. We categorized the number of previous illness episodes into "0-3″ and ">3 episodes", paired T-tests were used to compare the changes in scores of clinical assessments, generalized linear models were used to analyze the association between the number of previous illness episodes and change in symptomatic scores. A total of 1137 patients were included for analysis. There was a significant global improvement in psychiatric symptoms (CGI) after 6 ECT treatments across five indications. We observed that compared to patients with less previous illness episodes, patients with more than 3 previous illness episodes had 30% lower chance of response to acute ECT treatment. Thus, our study suggests that use ECT earlier in the course of illness is associated with greater response and support offering ECT earlier in the disease course.

Abstract
ABSTRACT Transcranial direct current stimulation (tDCS) is used in neuromodulation to regulate the excitability of the cerebral cortex and induce neural plasticity. It was initially used to rehabilitate patients with neurological diseases. However, with the increasing number of studies involving healthy individuals, this technology is currently used in the field of sports as well. The administration of tDCS to the cerebral cortex, especially over the primary motor cortex (M1), has been found to improve muscle strength, enhance endurance, and promote motor skills in humans. This study mainly summarizes the effects of tDCS on motor function, mainly involving motor promotion of tDCS in healthy athletes and nonathletes, and in patients diagnosed with neurological diseases. The tDCS is a promising and effective tool used to promote motor function by regulating cortical excitability. However, no consensus is available regarding individually appropriate models of tDCS.
