[Diagnosis and treatment of late-life depression]. / Diagnostic et traitement de la dépression de la personne âgée.

Late-life depression is a common pathology. The diagnosis can be difficult to make, due to intricacy of comorbidities, aging and treatments. The presentation is frequently atypical, with a high prevalence of somatic complaints. Depression is, in fact, underdiagnosed in this population and, when it is, poorly managed. This pathology constitutes a real public health problem due to impairment of functioning and quality of life, increase of comorbidities, use of health care and overall mortality, particularly by suicide. Treatment consists of psychotherapy, pharmacotherapy and/or electroconvulsive therapy.

La dépression unipolaire chez la personne âgée est une pathologie fréquente dont le diagnostic peut être difficile à poser, en raison de l'intrication des plaintes liées au vieillissement, aux comorbidités et aux traitements. La présentation est souvent atypique, avec une fréquence majorée de plaintes somatiques. Elle est, de ce fait, sous-diagnostiquée dans cette population, et lorsqu'elle l'est, souvent mal prise en charge. Pourtant, cette pathologie constitue un réel problème de santé publique par l'altération du fonctionnement et de la qualité de vie, ainsi que par la majoration des comorbidités, du recours aux soins de santé et de la mortalité globale, notamment par suicide. Le traitement est composé de psychothérapie, de pharmacothérapie et/ou d'électroconvulsivothérapie.

Transient Fever Response After ECT in a Patient with Catatonic Schizophrenia: A Case Report. / Katatonik Sizofreni Hastasinda EKT Sonrasi Ortaya Çikan Geçici Ates Yaniti: Olgu Sunumu.

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.

Magnetic Seizure Therapy vs Modified Electroconvulsive Therapy in Patients With Bipolar Mania: A Randomized Clinical Trial.

Importance: Bipolar mania is a common disabling illness. Electroconvulsive therapy (ECT) is an effective treatment for patients with severe mania, though it is limited by the risk of cognitive adverse effects. Magnetic seizure therapy (MST) as an alternative treatment to ECT for bipolar mania has not yet been reported. Objective: To compare the effectiveness and cognitive adverse effects of MST and ECT in bipolar mania. Design, Setting, and Participants: This randomized clinical trial was conducted at the Shanghai Mental Health Center from July 1, 2017, through April 26, 2021. Forty-eight patients with bipolar mania were recruited and randomly allocated to receive MST or ECT. The data analysis was performed from June 5, 2021, through August 30, 2023. Interventions: Patients completed 2 or 3 sessions of MST or ECT per week for a total of 8 to 10 sessions. The MST was delivered at 100% device output with a frequency of 75 Hz over the vertex. Main Outcomes and Measures: The primary outcomes were reduction of total Young Manic Rating Scale (YMRS) score and response rate (more than 50% reduction of the total YMRS score compared with baseline). An intention-to-treat (ITT) analysis and repeated-measures analyses of variance were conducted for the primary outcomes. Results: Twenty patients in the ECT group (mean [SD] age, 31.6 [8.6] years; 12 male [60.0%]) and 22 patients in the MST group (mean [SD] age, 34.8 [9.8] years; 15 male [68.2%]) were included in the ITT analysis. The response rates were 95.0% (95% CI, 85.4%-100%) in the ECT group and 86.4% (95% CI, 72.1%-100%) in the MST group. The YMRS reduction rate (z = -0.82; 95% CI, -0.05 to 0.10; P = .41) and response rate (χ2 = 0.18; 95% CI, -0.13 to 0.31; P = .67) were not significantly different between the groups. The time-by-group interaction was significant for the language domain (F1,24 = 7.17; P = .01), which was well preserved in patients receiving MST but worsened in patients receiving ECT. No serious adverse effects were reported in either group. Conclusions and Relevance: These findings suggest that MST is associated with a high response rate and fewer cognitive impairments in bipolar mania and that it might be an alternative therapy for the treatment of bipolar mania.

Successful Recovery of a Catatonic Patient with Severe Pneumonia and Respiratory Failure: Modified Electroconvulsive Therapy Following Tracheotomy.

BACKGROUD: Catatonia encompasses a group of severe psychomotor syndromes affecting patients' motor, speech, and complex behaviors. Common features include rigidity, reduced mobility, speech, sputum production, defecation, and eating. Risks associated with catatonia, such as increased muscle tension and reduced swallowing and coughing reflexes, along with risks from therapeutic approaches like prolonged bed rest and sedative drugs, can elevate the risk of aspiration pneumonia, severe pneumonia, and acute respiratory failure. These complications significantly impede catatonia treatment, leading to poor prognosis and jeopardizing patient safety. CASE DESCRIPTION: In this report, we present a case of catatonia complicated by severe pneumonia and respiratory failure, successfully managed with modified electroconvulsive therapy alongside tracheotomy. We hope this case provides valuable insights for psychiatrists encountering similar scenarios, facilitating the development of rational therapeutic strategies for prompt improvement of patient condition.

Clinical characteristics and treatment exposure of patients with marked treatment-resistant unipolar major depressive disorder: A RECOVER trial report.

BACKGROUND: RECOVER is a randomized sham-controlled trial of vagus nerve stimulation and the largest such trial conducted with a psychiatric neuromodulation intervention. OBJECTIVE: To describe pre-implantation baseline clinical characteristics and treatment history of patients with unipolar, major depressive disorder (MDD), overall and as a function of exposure to interventional psychiatric treatments (INTs), including electroconvulsive therapy, transcranial magnetic stimulation, and esketamine. METHODS: Medical, psychiatric, and treatment records were reviewed by study investigators and an independent Study Eligibility Committee prior to study qualification. Clinical characteristics and treatment history (using Antidepressant Treatment History [Short] Form) were compared in those qualified (N = 493) versus not qualified (N = 228) for RECOVER, and among the qualified group as a function of exposure to INTs during the current major depressive episode (MDE). RESULTS: Unipolar MDD patients who qualified for RECOVER had marked TRD (median of 11.0 lifetime failed antidepressant treatments), severe disability (median WHODAS score of 50.0), and high rate of baseline suicidality (77% suicidal ideation, 40% previous suicide attempts). Overall, 71% had received at least one INT. Compared to the no INT group, INT recipients were younger and more severely depressed (QIDS-C, QIDS-SR), had greater suicidal ideation, earlier diagnosis of MDD, and failed more antidepressant medication trials. CONCLUSIONS: RECOVER-qualified unipolar patients had marked TRD and marked treatment resistance with most failing one or more prior INTs. Treatment with ≥1 INTs in the current MDE was associated with earlier age of MDD onset, more severe clinical presentation, and greater treatment resistance relative to patients without a history of INT. TRIAL REGISTRATION: ClinicalTrials.gov Identifier NCT03887715.

The efficacy of electroconvulsive therapy in adolescent major depressive disorder with suicidal ideation: A propensity score-matched, retrospective cohort study.

BACKGROUND: More evidence is needed to validate the use of ECT in adolescent depression. This study aims to compare the effectiveness of electroconvulsive therapy (ECT) to conventional medication therapy for adolescents with major depression with suicidal ideation. METHODS: In this retrospective cohort study, we reviewed inpatient records from the First Affiliated Hospital of Chongqing Medical University spanning December 2016 to June 2021. We focused on adolescents diagnosed with severe depression presenting with suicidal tendencies. To equalize baseline differences between patients, we used the one-to-one propensity score matching to match patients who received ECT treatment with those who did not. Multivariate regression analysis was utilized to adjust for potential confounders, and subgroup analyses and sensitivity analyses were conducted to verify the robustness of our findings. RESULTS: Of the 626 patients in this study, 474 underwent ECT treatment while 152 received medication treatment, all aged between 10 and 18 years. Once matched, each group contained 143 patients. The ECT group demonstrated a significantly higher response rate and greater reductions in both Hamilton Depression Rating Scale and Hamilton Anxiety Scale scores (all P < 0.001). Additionally, the ECT group was more effective in reducing suicidal ideation, with fewer individuals retaining such ideation at discharge. In the multivariable regression analysis, both ECT treatment and shorter disease duration were independently linked to enhanced antidepressant efficacy. Subgroup analyses and sensitivity analyses verified the robustness of the main study effect. CONCLUSIONS: For adolescents with major depressive disorder and suicidal ideation, combining ECT with pharmacotherapy is more effective than pharmacotherapy alone before medications reach full effect.

Neurobiological mechanisms and therapeutic impact of electroconvulsive therapy (ECT).

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.

Exploring Brain and Heart Interactions during Electroconvulsive Therapy with Point-of-Care Ultrasound.

BACKGROUND: Electroconvulsive therapy (ECT) is a procedure commonly used to treat a number of severe psychiatric disorders, including pharmacologic refractory depression, mania, and catatonia by purposefully inducing a generalized seizure that results in significant hemodynamic changes as a result of an initial transient parasympathetic response that is followed by a marked sympathetic response from a surge in catecholamine release. While the physiologic response of ECT on classic hemodynamic parameters such as heart rate and blood pressure has been described in the literature, real-time visualization of cardiac function using point-of-care ultrasound (POCUS) during ECT has never been reported. This study utilizes POCUS to examine cardiac function in two patients with different ages and cardiovascular risk profiles undergoing ECT. METHODS: Two patients, a 74-year-old male with significant cardiovascular risks and a 23-year-old female with no significant cardiovascular risks presenting for ECT treatment, were included in this study. A portable ultrasound device was used to obtain apical four-chamber images of the heart before ECT stimulation, after seizure induction, and 2 min after seizure resolution to assess qualitative cardiac function. Two physicians with expertise in echocardiography reviewed the studies. Hemodynamic parameters, ECT settings, and seizure duration were recorded. RESULTS: Cardiac standstill was observed in both patients during ECT stimulation. The 74-year-old patient with a significant cardiovascular risk profile exhibited a transient decline in cardiac function during ECT, while the 23-year-old patient showed no substantial worsening of cardiac function. These findings suggest that age and pre-existing cardiovascular conditions may influence the cardiac response to ECT. Other potential contributing factors to the cardiac effects of ECT include the parasympathetic and sympathetic responses, medication regimen, and seizure duration with ECT. This study also demonstrates the feasibility of using portable POCUS for real-time cardiac monitoring during ECT. CONCLUSION: This study reports for the first time cardiac standstill during ECT stimulation visualized using POCUS imaging. In addition, it reports on the potential differential impact of ECT on cardiac function based on patient-specific factors such as age and cardiovascular risks that may have implications for ECT and perioperative anesthetic management and optimization.

Clinical efficacy of adjunctive esketamine anesthesia in electroconvulsive therapy for major depressive disorders: A pragmatic, randomized, controlled trial.

Electroconvulsive therapy (ECT) is an effective treatment for depression, and esketamine has been shown to have antidepressant effects. However, it is currently unclear whether adjunctive esketamine can enhance the clinical efficacy of ECT in real-world clinical practice. In this pragmatic clinical trial, patients with major depression were randomly assigned into two groups: patients received 0.25 mg/kg esketamine plus propofol (esketamine group) or the same volume of saline (control group) plus propofol. Results indicated that there was no difference in response and remission rates between the two groups. However, patients receiving esketamine had a higher remission rate of SI and lower psychotic scores. Patients receiving esketamine also required a lower electric dose, but the seizure duration and cognitive function were comparable between the two groups. Diastolic blood pressure increased after esketamine injection, but there was no increased risk of hypertension. Furthermore, incidence of delirium and confusion were comparable between the groups. Conclusively, adjunctive esketamine anesthesia does not provide any advantage in improving the response and remission rates of ECT. However, it can improve remission of SI and alleviate accompanying psychotic symptoms in depressive patients. With adjunctive usage, the adverse cardiovascular and neuropsychiatric events associated with esketamine appear to be tolerable.

Development, validation and clinical utility of short-term adverse-effects of electroconvulsive therapy (SAVE) checklist.

Electroconvulsive therapy (ECT) is one of the most effective treatments in psychiatry. However, it has many cognitive and non-cognitive adverse effects (AEs). There are lacunae in the literature on systematic assessment of non-cognitive AEs. There is a need for a standard, comprehensive and specific clinical tool to evaluate this. Hence, a checklist of short-term AEs of ECT (SAVE) with a 2-phase assessment was developed. Content validation was done using 15 experts' ratings and predefined content validity ratio and index (CVR and CVI) in a two-stage modified Delphi method. The checklist had a good CVR and CVI with a final tool of 39 items. The tool was sensitive and identified the non-cognitive AEs after ECT. Cardiovascular and musculoskeletal systems displayed the highest incidence. Many participants exhibited delayed recovery in orientation, gait, and stance, highlighting a necessity for meticulous monitoring. SAVE is the first standardised tool to assess short-term ECT-related AEs systematically. This checklist likely identifies clinically significant incidences of adverse effects. Its regular use may enhance the safety of ECT and patient comfort by supporting early identification and intervention for AEs. However, given the transient nature of AEs, further studies are needed to determine their predictive validity for long-term consequences.

Mechanism of electroconvulsive therapy in schizophrenia: a bioinformatics analysis study of RNA-seq data.

OBJECTIVE: The molecular mechanism of electroconvulsive therapy (ECT) for schizophrenia remains unclear. The aim of this study was to uncover the underlying biological mechanisms of ECT in the treatment of schizophrenia using a transcriptional dataset. METHODS: The peripheral blood mRNA sequencing data of eight patients (before and after ECT) and eight healthy controls were analyzed by integrated co-expression network analysis and the differentially expressed genes were analyzed by cluster analysis. Gene set overlap analysis was performed using the hypergeometric distribution of phypfunction in R. Associations of these gene sets with psychiatric disorders were explored. Tissue-specific enrichment analysis, gene ontology enrichment analysis, and protein-protein interaction enrichment analysis were used for gene set organization localization and pathway analysis. RESULTS: We found the genes of the green-yellow module were significantly associated with the effect of ECT treatment and the common gene variants of schizophrenia ( P  = 0.0061; family-wise error correction). The genes of the green-yellow module are mainly enriched in brain tissue and mainly involved in the pathways of neurotrophin, mitogen-activated protein kinase and long-term potentiation. CONCLUSION: Genes associated with the efficacy of ECT were predominantly enriched in neurotrophin, mitogen-activated protein kinase and long-term potentiation signaling pathways.

Molecular basis underlying changes of brain entropy and functional connectivity in major depressive disorders after electroconvulsive therapy.

INTRODUCTION: Electroconvulsive therapy (ECT) is widely used for treatment-resistant depression. However, it is unclear whether/how ECT can be targeted to affect brain regions and circuits in the brain to dynamically regulate mood and cognition. METHODS: This study used brain entropy (BEN) to measure the irregular levels of brain systems in 46 major depressive disorder (MDD) patients before and after ECT treatment. Functional connectivity (FC) was further adopted to reveal changes of functional couplings. Moreover, transcriptomic and neurotransmitter receptor data were used to reveal genetic and molecular basis of the changes of BEN and functional connectivities. RESULTS: Compared to pretreatment, the BEN in the posterior cerebellar lobe (PCL) significantly decreased and FC between the PCL and the right temporal pole (TP) significantly increased in MDD patients after treatment. Moreover, we found that these changes of BEN and FC were closely associated with genes' expression profiles involved in MAPK signaling pathway, GABAergic synapse, and dopaminergic synapse and were significantly correlated with the receptor/transporter density of 5-HT, norepinephrine, glutamate, etc. CONCLUSION: These findings suggest that loops in the cerebellum and TP are crucial for ECT regulation of mood and cognition, which provides new evidence for the antidepressant effects of ECT and the potential molecular mechanism leading to cognitive impairment.

Restoration of postictal cortical activity after electroconvulsive therapy relates to recovery of orientation in person, place, and time.

BACKGROUND: Most patients show temporary impairments in clinical orientation after electroconvulsive therapy (ECT)-induced seizures. It is unclear how postictal reorientation relates to electroencephalography (EEG) restoration. This relationship may provide additional measures to quantify postictal recovery and shed light on neurophysiological aspects of reorientation after ECT. METHODS: We analyzed prospectively collected clinical and continuous ictal and postictal EEG data from ECT patients. Postictal EEG restoration up to 1 h was estimated by the evolution of the normalized alpha-delta ratio (ADR). Times to reorientation in the cognitive domains of person, place, and time were assessed postictally. In each cognitive domain, a linear mixed model was fitted to investigate the relationships between time to reorientation and postictal EEG restoration. RESULTS: In total, 272 pairs of ictal-postictal EEG and reorientation times of 32 patients were included. In all domains, longer time to reorientation was associated with slower postictal EEG recovery. Longer seizure duration and postictal administration of midazolam were related to longer time to reorientation in all domains. At 1-hour post-seizure, most patients were clinically reoriented, while their EEG had only partly restored. CONCLUSIONS: We show a relationship between postictal EEG restoration and clinical reorientation after ECT-induced seizures. EEG was more sensitive than reorientation time in all domains to detect postictal recovery beyond 1-hour post-seizure. Our findings indicate that clinical reorientation probably depends on gradual cortical synaptic recovery, with longer seizure duration leading to longer postsynaptic suppression after ECT seizures.
