Personalidade Obsessivo-Compulsiva

Da Wikipedia:

Obsessive-compulsive personality disorder (OCPD), or anankastic personality disorder, is a personality disorder that is characterized by a general psychological inflexibility, rigid conformity to rules and procedures, perfectionism, and excessive orderliness.

People with OCPD may hoard money, keep their home perfectly organized, or be anxious about delegating tasks for fear that they won't be completed correctly. There are few moral gray areas for a person with OCPD; actions and beliefs are either completely right, or absolutely wrong. As might be expected, interpersonal relationships are difficult because of the excessive demands placed on friends, romantic partners, and children.

Além do mais, é bem capaz de ser hereditário.
