Abstract
Obsessive-compulsive (OC)-spectrum conditions consist of neurological-motoric conditions, impulse-control disorders, and disorders associated with bodily preoccupation. This article is a review of some understudied OC-spectrum conditions, with particular focus on phenomenology and overlap with obsessive-compulsive disorder, etiology, treatment outcome, treatment refractory issues, and new developments in treatment research. The focus will be on representative disorders from each related area, namely, Tourette's syndrome, trichotillomania, skin-picking, and body dysmorphic disorder. Similarities among the disorders and areas in need of more research are discussed.
