obsessive-compulsive personality disorder

Obsessive–compulsive personality disorder (OCPD) is a personality disorder marked by a spectrum of obsessions with rules, lists, schedules, and order, among other things. Symptoms are usually present by the time a person reaches adulthood, and are visible in a variety of situations. The cause of OCPD is thought to involve a combination of genetic and environmental factors, namely problems with attachment, but in some individuals there may be a link to brain trauma or Parkinson's disease.

Obsessive–compulsive personality disorder is distinct from obsessive–compulsive disorder (OCD), and the relation between the two is contentious. Some studies have found high comorbidity rates between the two disorders but others have shown little comorbidity. Both disorders may share outside similarities, such as rigid and ritual-like behaviors. OCPD is highly comorbid with other personality disorders, autism spectrum, eating disorders, anxiety, mood disorders, and substance use disorders. People with OCPD are seldom conscious of their actions, while people with OCD tend to be aware of how their condition affects the way they act.
