    • 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 ...

    • 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.

      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 ...

    • 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 ...

    • Electroconvulsive therapy-induced volumetric brain changes converge on a common causal circuit in depression 

      Argyelan, Miklos; Deng, Zhi-De; Ousdal, Olga Therese; Oltedal, Leif; Angulo, Brian; Baradits, Mate; Spitzberg, Andrew J.; Kessler, Ute; Sartorius, Alexander; Dols, Annemiek; Narr, Katherine L.; Espinoza, Randall; van Waarde, Jeroen A.; Tendolkar, Indira; van Eijndhoven, Philip; van Wingen, Guido A.; Takamiya, Akihiro; Kishimoto, Taishiro; Jorgensen, Martin B.; Jorgensen, Anders; Paulson, Olaf B.; Yrondi, Antoine; Péran, Patrice; Soriano-Mas, Carles; Cardoner, Narcis; Cano, Marta; van Diermen, Linda; Schrijvers, Didier; Belge, Jean-Baptiste; Emsell, Louise; Bouckaert, Filip; Vandenbulcke, Mathieu; Kiebs, Maximilian; Hurlemann, René; Mulders, Peter Cr.; Redlich, Ronny; Dannlowski, Udo; Erhan, Kavakbasi; Kritzer, Michael D.; Ellard, Kristen K.; Camprodon, Joan A.; Petrides, Georgios; Malhotra, Anil K.; Abbott, Christopher C. (Journal article; Peer reviewed, 2023)
      Neurostimulation is a mainstream treatment option for major depression. Neuromodulation techniques apply repetitive magnetic or electrical stimulation to some neural target but significantly differ in their invasiveness, ...
