Obsessive-compulsive personality disorder (OCPD), also known as anankastic personality disorder, presents a persistent pattern of behavior that includes a fixation on orderliness, perfectionism, excessive attention to details, mental and interpersonal control, and a need for control over one's environment. Persons who suffer from this employ rituals in their daily life to the point of excluding leisure activities and experience a great of mental distress when in a situation that they cannot control.
