Older age associated with better antidepressant response to H1-coil transcranial magnetic stimulation in female patients.

Background: TMS is increasingly used to treat depression, but predictors of treatment outcomes remain unclear. We assessed the association between age and TMS response given inconsistent prior reports limited by small sample size, heterogeneity, outdated TMS parameters, lack of assessment of H1-coil TMS, and lack of an a priori hypothesis. We hypothesized that older age would be associated with better treatment response based on trends in recent large exploratory analyses.

Efficacy and safety of ketamine-assisted electroconvulsive therapy in major depressive episode: a systematic review and network meta-analysis.

Objective: To meta-analyze clinical efficacy and safety of ketamine compared with other anesthetic agents in the course of electroconvulsive therapy (ECT) in major depressive episode (MDE).

Methods: PubMed/MEDLINE, Cochrane Library, Embase, GoogleScholar, and US and European trial registries were searched from inception through May 23, 2023, with no language limits. We included RCTs with (1) a diagnosis of MDE; (2) ECT intervention with ketamine and/or other anesthetic agents; and (3) measures included: depressive symptoms, cognitive performance, remission or response rates, and serious adverse events.

A Novel Approach to Monitoring Cognitive Adverse Events for Interventional Studies Involving Advanced Dementia Patients: Insights From the Electroconvulsive Therapy for Agitation in Dementia Study.

Objective: To develop an individualized method for detecting cognitive adverse events (CAEs) in the context of an ongoing trial of electroconvulsive therapy for refractory agitation and aggression for advanced dementia (ECT-AD study).

Methods: Literature search aimed at identifying (a) cognitive measures appropriate for patients with advanced dementia, (b) functional scales to use as a proxy for cognitive status in patients with floor effects on baseline cognitive testing, and (c) statistical approaches for defining a CAE, to develop CAEs monitoring plan specifically for the ECT-AD study.

Results: Using the Severe Impairment Battery-8 (SIB-8), baseline floor effects are defined as a score of ≤5/16.

Residual symptoms following electroconvulsive therapy: A retrospective cohort study.

Background: Residual depressive symptoms following treatment are a burden for patients and are associated with increased risk of relapse. While this phenomenon has been explored following pharmacotherapy, there is little research into residual symptoms following electroconvulsive therapy (ECT). This study quantifies the frequency and type of residual symptoms following ECT treatment.

A Pilot Study of Adjunctive Group Therapy to Enhance Coping With Cognitive Challenges and Support Cognitive Health After Electroconvulsive Therapy.

Objectives: Concerns about the cognitive adverse effects of electroconvulsive therapy (ECT) are common among recipients of the treatment despite its relatively small adverse effects on cognitive functioning. Interventions aimed at remediating or improving coping with cognitive adverse effects of ECT have not been developed. The Enhancing Cognitive Domains after ECT (ENCODE) program is a new group intervention aimed at teaching self-management strategies to cope with the cognitive challenges and associated anxiety that often accompanies ECT.

Factors associated with early and late response to electroconvulsive therapy.

Objective: Electroconvulsive therapy (ECT) is an effective treatment for severe depressive symptoms, yet more research is needed to examine predictors of treatment response, and factors associated with response in patients not initially improving with treatment. This study reports factors associated with time to response (early vs. late) to ECT in a real-world setting.

National Network of Depression Centers' Recommendations on Harmonizing Clinical Documentation of Electroconvulsive Therapy.

Electroconvulsive therapy (ECT) is a highly therapeutic and cost-effective treatment for severe and/or treatment-resistant major depression. However, because of the varied clinical practices, there is a great deal of heterogeneity in how ECT is delivered and documented. This represents both an opportunity to study how differences in implementation influence clinical outcomes and a challenge for carrying out coordinated quality improvement and research efforts across multiple ECT centers.

The Duration in Treatment With Electroconvulsive Therapy Among Patients Screening Positive or Negative for Borderline Personality Disorder Traits: A Retrospective Cohort Study.

Objective: While emerging evidence suggests that electroconvulsive therapy (ECT) is an effective treatment for depressive symptoms in patients with co-occurring borderline personality disorder (BPD) traits, it is unclear whether the presence of BPD traits modulates the tolerability of ECT. This study estimates the association between BPD traits and retention in acute course ECT treatment.

Methods: This study used a retrospective cohort of patients receiving ECT between 2015 and 2020 and who were assessed using the McLean Screening Instrument for BPD, the Quick Inventory of Depressive Symptomatology Self-Report 16-item scale, and the Montreal Cognitive Assessment before initiating treatment.

Simulated Electroconvulsive Therapy: A Novel Approach to a Control Group in Clinical Trials.

Objectives: Agitation is the most common behavioral symptom of Alzheimer disease (AD) affecting approximately 40% to 60% of the AD population, yet there are no Food and Drug Administration-approved therapies for the myriad of behavioral or psychological symptoms of dementia. There is growing evidence from naturalistic studies that electroconvulsive therapy (ECT) is a safe and effective treatment for agitation in AD patients who are refractory to pharmacotherapy and behavioral interventions. Despite the existing evidence, ECT remains underused because of stigma, lack of education, and concerns regarding adverse cognitive effects.

The Effects of Baseline Impaired Global Cognitive Function on the Efficacy and Cognitive Effects of Electroconvulsive Therapy in Geriatric Patients: A Retrospective Cohort Study.

Objectives: This study explores the association between baseline impaired global cognitive function and changes in global cognitive function and depression among geriatric patients undergoing acute course electroconvulsive therapy (ECT).

Design: Retrospective cohort study.

Setting: Single freestanding psychiatric hospital.

First Acute-Course Electroconvulsive Therapy for Moderate-to-Severe Depression Benefits Patients With or Without Accompanying Baseline Cognitive Impairment.

Background: Researchers are increasingly investigating therapeutic response associated with new patient subgroups as a way to improve electroconvulsive therapy (ECT) treatment outcomes and reduce adverse events. This study is the first to examine baseline cognitive impairment status as a predictor of clinical outcome in first acute-course ECT patients.

Methods: Baseline cognitive function at various thresholds and serial depressive symptom severity data from first-time ECT patients were examined using generalized linear mixed-effects models.

Treatment of Electroconvulsive Therapy-Emergent Hypomania and Mania: A Systematic Review of the Literature.

Electroconvulsive therapy (ECT)-emergent hypomania/mania is a clinically significant problem that has lacked evidence-based guidelines for effective management. The aim of this systematic literature review is to compile the current published literature on treating ECT-emergent hypomania/mania to help guide treatment course in patients with unipolar and bipolar depression. MEDLINE/PubMed was searched for studies published from 1980 through August 2020 that evaluated the treatment of ECT-emergent hypomania/mania.

Individual response to electroconvulsive therapy is not correlated between multiple treatment courses.

Objectives: Electroconvulsive therapy (ECT) effectively treats depressive disorders, but many patients will have subsequent relapses. While some guidelines suggest prior response to ECT is an indication for ECT in a subsequent mood episode, it is unknown whether response to ECT is correlated between treatment courses. This study explores whether response to ECT at a first treatment correlates with response to treatment in a second independent ECT course.

Real-world evidence of age-independent electroconvulsive therapy efficacy: A retrospective cohort study.

Objectives: Electroconvulsive therapy (ECT) is an effective treatment for depressive disorders and approved for use in adolescents and adults, but it is unclear whether efficacy or cognitive side effect burden differs with age or if effectiveness in usual clinical practice matches that in prospective studies. We examined the effects of ECT on depression and cognition in a large clinical cohort.

Methods: A retrospective cohort study of patients ages 16 and older receiving ECT between 2011 and 2020 and who were evaluated with the Quick Inventory of Depressive Symptomatology (QIDS), the Behavior and Symptom Identification Scale-24 (BASIS-24), and the Montreal Cognitive Assessment (MoCA) at baseline and after treatment #10.

The Efficacy and Cognitive Effects of Acute Course Electroconvulsive Therapy Are Equal in Adolescents, Transitional Age Youth, and Young Adults.

Electroconvulsive therapy (ECT) is the most effective acute treatment for depression, but its use in younger patients is rare and heavily regulated in many U.S. states.

Changes in seizure duration during acute course electroconvulsive therapy.

Background: Seizure duration has long been measured as a potential marker of ECT treatment efficacy, with concern that short seizures may be clinically ineffective. Relatively small studies have documented a trend towards shorter seizures during acute course ECT, but data from large cohorts would help provide normative data on seizure duration changes during treatment.

Objective: This study analyzes the effects of age, sex, ECT dose, and treatment number on the duration of electrographic seizures during acute course ECT in a large single-center cohort.

Duration of Treatment in Electroconvulsive Therapy Among Patients Beginning With Acute Course Right Unilateral Brief Pulse Stimuli.

Objectives: Right unilateral brief pulse (RUL-BP) electroconvulsive therapy (ECT) has been adopted as a technique for reducing the cognitive side effects of ECT relative to sine wave or bilateral treatments, but it is unknown how often patients are transitioned to alternative electrode placements. This study analyzes time in first lifetime acute course RUL-BP ECT.

Methods: A single-center retrospective chart review was conducted of adult patients receiving a first lifetime course of ECT from 2000 to 2017 beginning with individualized seizure threshold determination using RUL-BP treatment parameters.

Borderline personality traits do not influence response to TMS.

Comorbid personality disorders are common in patients with major depressive disorder (MDD). Individuals with comorbid borderline personality disorder (BPD) may be less responsive to electroconvulsive therapy (ECT), but it remains unclear whether BPD affects responsiveness to transcranial magnetic stimulation (TMS). We sought to investigate the association between BPD and response to TMS.

Rate of continuing acute course treatment using right unilateral ultrabrief pulse electroconvulsive therapy at a large academic medical center.

Right unilateral ultrabrief pulse (RUL-UBP) ECT has emerged as a promising technique for minimizing cognitive side effects of ECT while retaining clinical efficacy, but it is unknown how often patients will require alternative treatment parameters and at what point in the treatment course this occurs. To better define this problem, this study analyzes continuation in RUL-UBP ECT in a retrospective cohort of patients beginning acute course treatment. A single-center retrospective chart review was conducted of adult patients receiving a first lifetime course of ECT from 2010 to 2017 starting with RUL-UBP treatment parameters.
