Primarily obsessional obsessive compulsive disorder
Primarily cognitive obsessive-compulsive disorder is a lesser-known form or manifestation of OCD. For people with primarily obsessional OCD, there are fewer observable compulsions, compared to those commonly seen with the typical form of OCD. While ritualizing and neutralizing behaviors do take place, they are mostly cognitive in nature, involving mental avoidance and excessive rumination. Primarily obsessional OCD takes the form of intrusive thoughts of a distressing or violent nature.
