102 unresolved questions extracted from the limitations and future-work sections of 599 Electroconvulsive Therapy Studies papers in our library. Each links back to the study that raised it.

What the literature leaves open

  • further studies using administrative health data to assess rare or long-term outcomes, - investigation of ECT's association with other clinical outcomes, - examination of the effectiveness of ECT in different populations

    Electroconvulsive therapy: improved understanding of long-term risks and benefits from advances in administrative health data · 2026 · DOI

  • Traditional clinical trials are impractical for assessing rare or long-term outcomes of ECT. Observational studies using administrative health data are limited by confounding/bias. There is a need to synthesise evidence from studies utilising administrative health data and modern statistical methods to address clinically relevant questions about ECT's association with dementia, major adverse cardiovascular/cerebrovascular events, suicide deaths, and all-cause mortality.

  • further study of methamphetamine withdrawal catatonia, - investigation of the effectiveness of mixed amphetamine salts in treating methamphetamine withdrawal catatonia, - exploration of the underlying pathophysiology of methamphetamine withdrawal catatonia

    Methamphetamine-withdrawal catatonia resolved with mixed amphetamine salts: a case report · 2026 · DOI

  • Methamphetamine withdrawal is a potential cause of catatonia that has not been well characterized. Standard treatments for catatonia may not be effective in some cases, particularly those related to methamphetamine withdrawal. There is a need for further research on the treatment of refractory catatonia, including the potential use of dopaminergic augmentation.

    Methamphetamine-withdrawal catatonia resolved with mixed amphetamine salts: a case report · 2026 · DOI

  • further studies are needed to replicate these findings and explore the underlying mechanisms - research should investigate the optimal ECT procedures and parameters for different patient populations - studies should examine the relationship between ECT response and other clinical features, such as depression polarity and medication resistance

    Why is electroconvulsive therapy for depression more effective in older age? A causal mediation analysis · 2025 · DOI

  • The study identifies a gap in understanding why ECT is more effective in older adults with depression. The study aims to investigate the mediators of the effect of age on ECT response.

    Why is electroconvulsive therapy for depression more effective in older age? A causal mediation analysis · 2025 · DOI

  • Further studies are needed to understand the mechanisms of ECT. Research on the effects of ECT on brain structure and function is necessary. Studies on the relationship between GMV changes and clinical symptoms are required.

    Alterations in gray matter volume and associated transcriptomics after electroconvulsive therapy in major depressive disorder · 2025 · DOI

  • The mechanism of action of ECT remains unclear. There is a lack of understanding of the changes in gray matter volume in patients with MDD caused by ECT. The potential functional mechanisms of ECT are not well explored.

    Alterations in gray matter volume and associated transcriptomics after electroconvulsive therapy in major depressive disorder · 2025 · DOI

  • Due to limited information, causal links between mECT and many adverse events were difficult to establish and inferences about differential effectiveness and safety between important patient subgroups or variations in mECT technique could not be drawn.

    Modified electroconvulsive therapy for perinatal depression: scoping review · 2025 · DOI

  • Introduction Electroconvulsive therapy (ECT) remains a critical intervention for treatment-resistant depression (MDD), yet its neurobiological underpinnings are not fully understood.

    Electroconvulsive therapy modulates loudness dependence of auditory evoked potentials: a pilot MEG study · 2024 · DOI

  • Introduction: Electroconvulsive therapy (ECT) is the most effective treatment for patients suffering from treatment-resistant depression but its use is often limited by the concern for cognitive side effects.

    Role of stimulus dose on neuropsychological functioning after electroconvulsive therapy in patients with major depressive disorder · 2024 · DOI

  • Magnetic seizure therapy (MST) as an alternative treatment to ECT for bipolar mania has not yet been reported.

    Magnetic Seizure Therapy vs Modified Electroconvulsive Therapy in Patients With Bipolar Mania · 2024 · DOI

  • 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 vs Modified Electroconvulsive Therapy in Patients With Bipolar Mania · 2024 · DOI

  • There is a need to identify clinical features associated with ECT response in adolescents with MDD. Prior studies have not developed a concise explanatory model that can effectively stratify the risk of poor ECT efficacy.

    Identifying clinical features associated with electroconvulsive therapy response in adolescents with major depressive disorder using machine learning · 2026 · DOI

  • Hemodynamic instability during ECT. Prolonged recovery time after ECT. Unclear mechanism of ECT.

    Comparison of the Effects of Dexmedetomidine and Remifentanil on Seizure Duration, Hemodynamics, and Recovery Time in Electroconvulsive Therapy · 2026 · DOI

  • The exact mechanism of ECT remains unclear. There is a need to compare the effects of different anesthetics on seizure duration, hemodynamics, and recovery time in ECT.

    Comparison of the Effects of Dexmedetomidine and Remifentanil on Seizure Duration, Hemodynamics, and Recovery Time in Electroconvulsive Therapy · 2026 · DOI

  • There is a lack of literature on the use of ECT in patients with comorbid BD and PD. The diagnosis of PD can be challenging, especially in patients with comorbid psychiatric disorders. There is a need for further research on the treatment of catatonia in patients with PD.

    Management of catatonia in Parkinson’s disease with comorbid bipolar disorder: A case report and review of literature · 2026 · DOI

  • The existing literature on psychiatric disorders in PD has rarely examined the occurrence of BD. The occurrence of catatonia in comorbid BD and PD, and the efficacy 17 / 40 of ECT in this complex presentation, is based on only a few patient reports. Therefore, further research is essential to provide better insights regarding comorbid BD and PD with catatonia. Future research regarding BD and catatonia associated with PD should include larger, longitudinal studies, properly designed treatment trials, and investigations of underlying genetic, structural and functional mechanisms.

  • Physical movement and limited cooperation in pediatric patients. The need to balance patient quiescence and signal integrity during EEG recordings. The potential for sedative agents to produce distinct neurophysiological signatures that can obscure diagnostic landmarks.

    Neurophysiological Electroencephalography Signatures of Pediatric Sedation: A Comprehensive Comparative Review · 2026 · DOI

  • The current literature lacks rigorous spectral analyses of the specific effects of midazolam and ketamine on EEG background architecture. There is a need for a comprehensive evaluation of the effects of sedative agents on EEG signatures in pediatric patients.

    Neurophysiological Electroencephalography Signatures of Pediatric Sedation: A Comprehensive Comparative Review · 2026 · DOI

  • Further investigation into modafinil's neurobiological effects is warranted. The risk of modafinil-induced psychosis should be studied in larger populations.

    Modafinil Induced Psychosis in a Patient with Recurrent Depressive Disorder: A Case Report · 2026 · DOI

  • The mechanism of psychosis with modafinil is less studied. The contribution of low-dose venlafaxine in the production of psychotic symptoms needs to be explored.

    Modafinil Induced Psychosis in a Patient with Recurrent Depressive Disorder: A Case Report · 2026 · DOI

  • the inaccurate labeling of ECT as an invasive treatment - the lack of understanding of the concept of invasiveness in medical treatments

    ECT is not an invasive therapy · 2026 · DOI

  • Abstract Background and Hypothesis Catatonia is a transdiagnostic syndrome in schizophrenia spectrum disorders (SSD) and mood disorders (MOD), but both its empirical structure and the frequency of its signs and symptoms remain insufficiently understood.
