 OCPD is often confused with obsessive–compulsive disorder (OCD). Despite the similar names, they are two distinct disorders, although some OCPD individuals also suffer from OCD, and the two are sometimes found in the same family,[20] sometimes along with eating disorders.[21] People with OCPD do not generally feel the need to repeatedly perform ritualistic actions—a common symptom of OCD—and usually find pleasure in perfecting a task, whereas people with OCD are often more distressed after their actions.
