Personality disorder

Maladaptive patterns of behavior, cognition, and inner experience

A personality disorder (PD) is a mental disorder characterized by an enduring and pervasive maladaptive pattern of behavior, emotions, cognition, and inner experience, deviating from social norms. As a common feature, this manifests in significant impairment in interpersonal relationships and various aspects of functioning of the self, such as self-concept, in conjunction with pathological personality traits. These patterns develop early, are inflexible, and are associated with significant distress or disability.
