Cluster B Personality Disorders
Personality disorders are defined by enduring, inflexible, pervasive patterns of inner experience and behavior that deviate markedly from the expectations of an individual’s culture. This pattern manifests as deviations in cognition, affectivity, interpersonal functioning, and impulse control. It leads to significant distress or impairment in social, occupational, and/or other important areas of functioning.
Cluster B Personality Disorders are collectively characterized by dramatic, emotional, and erratic patterns of thoughts and behaviors:
- Antisocial Personality Disorder is a pattern of disregard for, and violation of, the rights of others.
