Diffusion Tensor Imaging Before and After Concentrated Exposure and Response Prevention in Obsessive-Compulsive Disorder

Abstract

Subtle differences in white matter microstructure have been found in obsessive-compulsive disorder (OCD) versus healthy controls using diffusion tensor imaging (DTI), but it’s unclear if this changes after treatment. This preregistered study therefore investigated changes in white matter microstructure after concentrated exposure and response prevention (ERP).
