Diffusion Tensor Imaging Before and 3 Months After Concentrated Exposure Response Prevention in Obsessive-Compulsive Disorder
Brecke, Vilde; Thorsen, Anders Lillevik; Ousdal, Olga Therese; Vriend, Chris; Alnæs, Dag; Hagen, Kristen; Hansen, Bjarne; Kvale, Gerd; van den Heuvel, Odile A (Journal article; Peer reviewed, 2021)Background: Subtle differences in white matter microstructure have been found in obsessive-compulsive disorder (OCD) compared to controls using diffusion tensor imaging (DTI), but it is unclear if and how this change after ... -
Disentangling Within- and Between-Person Effects During Response Inhibition in Obsessive-Compulsive Disorder
Hagland, Pernille; Thorsen, Anders Lillevik; Ousdal, Olga Therese; Gjestad, Rolf; de Wit, Stella J.; Hansen, Bjarne Kristian Aaslie; Hagen, Kristen; Kvale, Gerd; van den Heuvel, Odile A. (Journal article; Peer reviewed, 2021)Background: Obsessive-compulsive disorder (OCD) has been related to worse performance, abnormal brain activity, and functional connectivity during response inhibition. Whether these findings are indications of stable traits ... -
Effects of Bergen 4-Day Treatment on Resting-State Graph Features in Obsessive-Compulsive Disorder
Thorsen, Anders Lillevik; Vriend, Chris; de Wit, Stella J.; Ousdal, Olga Therese; Hagen, Kristen; Hansen, Bjarne; Kvale, Gerd; van den Heuvel, Odile A (Journal article; Peer reviewed, 2020)Background Exposure and response prevention is an effective treatment for obsessive-compulsive disorder (OCD), but it is unclear how symptom reduction is related to changes in the brain. We aimed to determine the effects ... -
The Emotional Brain in Obsessive-Compulsive Disorder
Thorsen, Anders Lillevik (Doctoral thesis, 2019-11-19)Background Obsessive-compulsive disorder (OCD) is characterized by distressing obsessions and time-consuming compulsions. The disorder affects 1-3% and can be highly impairing to daily functioning and detrimental to the ... -
Longitudinal changes in neurometabolite concentrations in the dorsal anterior cingulate cortex after concentrated exposure therapy for obsessive-compulsive disorder
de Joode, Niels T.; Thorsen, Anders Lillevik; Vester, Eline L.; Vriend, Chris; Pouwels, Petra J.W.; Hagen, Kristen; Ousdal, Olga Therese; Hansen, Bjarne Kristian Aaslie; Kvale, Gerd; van den Heuvel, Odile A. (Journal article; Peer reviewed, 2021)Background The dorsal anterior cingulate cortex (dACC) plays an important role in the pathophysiology of obsessive-compulsive disorder (OCD) due to its role in error processing, cognitive control and emotion regulation. ... -

However, previous Nordic studies have shown inconsistent results ... -
Stable inhibition-related inferior frontal hypoactivation and fronto-limbic hyperconnectivity in obsessive–compulsive disorder after concentrated exposure therapy
Thorsen, Anders Lillevik; de Wit, Stella J.; Hagland, Pernille; Ousdal, Olga Therese; Hansen, Bjarne; Hagen, Kristen; Kvale, Gerd; van den Heuvel, Odile A (Journal article; Peer reviewed, 2020)Response inhibition has previously been suggested as an endophenotype for obsessive–compulsive disorder (OCD), evidenced by studies showing worse task performance, and altered task-related activation and connectivity. ...
