OCPD is diffent from OCD which is obsessive compulsive disorder. OCPD is a more pervasive condition affecting the way a person looks at the world and at others. OCPD patients are enslaved to their needs for punctuality, orderliness, symmetry, color coordination, moral righteousness to name a few. This is perfectionism to the extreme. High levels of anger and anxiety result when their excessive needs are frustrated.
