    • Accounting for symptom heterogeneity can improve neuroimaging models of antidepressant response after electroconvulsive therapy 

      Wade, Benjamin; Hellemann, Gerhard S.; Espinoza, Randall; Woods, Roger P.; Joshi, Shantanu H.; Redlich, Ronny; Dannlowski, Udo; Jorgensen, Anders; Abbott, Christopher; Oltedal, Leif; Narr, Katherine L. (Journal article; Peer reviewed, 2021)
      Depression symptom heterogeneity limits the identifiability of treatment-response biomarkers. Whether improvement along dimensions of depressive symptoms relates to separable neural networks remains poorly understood. We ...

    • Anterior cingulate gamma-aminobutyric acid concentrations and electroconvulsive therapy 

      Erchinger, Vera Jane; Miller, Jeremy; Jones, Thomas; Kessler, Ute; Bustillo, Juan R.; Haavik, Jan; Petrillo, Jonathan; Ziomek, Gregory; Hammar, Åsa; Ødegaard, Ketil Joachim; Calhoun, Vince D.; McClintock, Shawn M.; Ersland, Lars; Oltedal, Leif; Abbott, Christopher (Journal article; Peer reviewed, 2020-09-17)
      Objective The anticonvulsant hypothesis posits that ECT’s mechanism of action is related to enhancement of endogenous anticonvulsant brain mechanisms. Results of prior studies investigating the role of the inhibitory ...

    • Brain changes induced by electroconvulsive therapy are broadly distributed 

      Ousdal, Olga Therese; Argyelan, Miklos; Narr, Katherine L.; Abbott, Christopher; Wade, Benjamin; Vandenbulcke, Mathieu; Urretavizcaya, Mikel; Tendolkar, Indira; Takamiya, Akihiro; Stek, Max L.; Soriano-Mas, Carles; Redlich, Ronny; Paulson, Olaf B.; Oudega, Mardien L.; Opel, Nils; Nordanskog, Pia; Kishimoto, Taishiro; Kämpe, Robin; Jørgensen, Anders; Hanson, Lars G.; Hamilton, J. Paul; Espinoza, Randall; Emsell, Louise; van Eijndhoven, Philip; Dols, Annemieke; Dannlowski, Udo; Cardoner, Narcis; Bouckaert, Filip; Anand, Amit; Bartsch, Hauke; Kessler, Ute; Ødegaard, Ketil Joachim; Dale, Anders; Oltedal, Leif (Peer reviewed; Journal article, 2020-03-01)
      Background Electroconvulsive therapy (ECT) is associated with volumetric enlargements of corticolimbic brain regions. However, the pattern of whole-brain structural alterations following ECT remains unresolved. Here, we ...

    • Development and validation of a multimodal neuroimaging biomarker for electroconvulsive therapy outcome in depression: A multicenter machine learning analysis 

      Bruin, Willem Benjamin; Oltedal, Leif; Bartsch, Hauke; Abbott, Christopher; Argyelan, Miklos; Barbour, Tracy; Camprodon, Joan; Chowdhury, Samadrita; Espinoza, Randall; Mulders, Peter; Narr, Katherine; Oudega, Mardien; Rhebergen, Didi; Ten Doesschate, Freek; Tendolkar, Indira; Van Eijndhoven, Philip; Van Exel, Eric; Van Verseveld, Mike; Wade, Benjamin; Van Waarde, Jeroen; Zhutovsky, Paul; Dols, Annemiek; Van Wingen, Guido (Journal article; Peer reviewed, 2023)
      Background Electroconvulsive therapy (ECT) is the most effective intervention for patients with treatment resistant depression. A clinical decision support tool could guide patient selection to improve the overall ...

    • Electric field causes volumetric changes in the human brain 

      Argyelan, Miklos; Oltedal, Leif; Deng, Zhi-De; Wade, Benjamin; Bikson, Marom; Joanlanne, Andrea; Sanghani, Sohag; Bartsch, Hauke; Cano, Marta; Dale, Anders M.; Dannlowski, Udo; Dols, Annemieke; Enneking, Verena; Espinoza, Randall; Kessler, Ute; Narr, Katherine L.; Ødegaard, Ketil Joachim; Oudega, Mardien L.; Redlich, Ronny; Stek, Max L.; Takamiya, Akihiro; Emsell, Louise; Bouckaert, Filip; Sienaert, Pascal; Pujol, Jesus; Tendolkar, Indira; van Eijndhoven, Philip; Petrides, Georgios; Malhotra, Anil K.; Abbott, Christopher (Peer reviewed; Journal article, 2019)
      Recent longitudinal neuroimaging studies in patients with electroconvulsive therapy (ECT) suggest local effects of electric stimulation (lateralized) occur in tandem with global seizure activity (generalized). We used ...

    • Magnetic Resonance Spectroscopy in Depressed Subjects Treated With Electroconvulsive Therapy—A Systematic Review of Literature 

      Erchinger, Vera Jane; Ersland, Lars; Aukland, Stein Magnus; Abbott, Christopher; Oltedal, Leif (Journal article; Peer reviewed, 2021)
      Electroconvulsive therapy (ECT) is considered to be the most effective acute treatment for otherwise treatment resistant major depressive episodes, and has been used for over 80 years. Still, the underlying mechanism of ...

    • Structural changes induced by electroconvulsive therapy are associated with clinical outcome 

      Mulders, Peter C. R.; Llera, Alberto; Beckmann, Christian F.; Vandenbulcke, Mathieu; Stek, Max L; Sienaert, Pascal; Redlich, Ronny; Petrides, Georgios; Oudega, Mardien L.; Oltedal, Leif; Ødegaard, Ketil Joachim; Narr, Katherine L; Magnusson, Peter; Kessler, Ute; Jorgensen, Anders; Espinoza, Randall; Enneking, Verena; Emsell, Louise; Dols, Annemieke; Dannlowski, Udo; Bolwig, Tom G; Bartsch, Hauke; Argyelan, Miklos; Anand, Amit; Abbott, Christopher; van Eijndhoven, Philip; Tendolkar, Indira (Journal article; Peer reviewed, 2020)
      Background Electroconvulsive therapy (ECT) is the most effective treatment option for major depressive disorder, so understanding whether its clinical effect relates to structural brain changes is vital for current and ...
