Tic
Individuals with obsessive–compulsive disorder (OCD) may present with features typically associated with a tic disorder, such as compulsions that may resemble motor tics. "Tic-related OCD" is hypothesized to be a subgroup of OCD, distinguished from non-tic-related OCD by the content and type of obsessions and compulsions; individuals with tic-related OCD have more intrusive thoughts, and exhibit more hoarding and counting rituals than individuals with non-tic-related OCD.
