Personality disorders are classified as lasting patterns of behavior manifested in thoughts, affect, interpersonal functioning, or impulse control that are different than the individual’s cultural expectations. Onset is typically in adolescence or early adulthood, patterns are often pervasive, inflexible, and maladaptive – typically leading to distress or impairment in personal and social situations. People who are diagnosed with personality disorders have often experienced emotional/physical abuse or neglect, resulting in a traumatic childhood. Personality disorders are grouped into three clusters based on similarities:
Cluster A: Odd or eccentric behavior are central themes in this group of personality disorders.
Cluster B: This cluster includes personality disorders in which dramatic and overly emotional reactions are common.
Cluster C: Anxious and fearful behavior characterize this cluster of personality disorders.
