Brief Summary
Obsessive-compulsive disorder (OCD) and anxiety disorders are common and debilitating conditions which are often chronic when treatment is not provided. International guidelines recommend cognitive behavioral therapy (CBT) as the first-line treatment, and research has shown that CBT can be delivered over a concentrated period of time. The Bergen 4-Day Treatment (B4DT) is an exposure-based treatment which is delivered over four consecutive days. B4DT has been shown to induce rapid and long-lasting remission in around 70% of patients. This provides a platform for studying psychological and neurobiological changes associated with treatment response and non-response. The present study will investigate longitudinal changes in psychological measures and DNA methylation in patients who receive the B4DT, as well as a subset will also undergo multimodal brain imaging.

Study Arms (2)
Patients with obsessive-compulsive, social anxiety or panic disorder
Patients with obsessive-compulsive disorder. The MRI substudy will also include patients with social anxiety or panic disorder
For MRI substudy: Healthy controls
Healthy controls demographically matched to the patient group on age, sex and years of education
Interventions
A concentrated and exposure-based psychological treatment over four consecutive days
