Personality disorders are characterized by a long-lasting, rigid pattern of maladaptive thoughts, feelings, and behaviors. This enduring pattern of inner experience and behavior deviates markedly from the expectations of the individual’s culture. Because of the inflexibility and pervasiveness of these patterns, they cause serious relational problems and impairment of functioning for the afflicted individual.

The DSM-5 lists Borderline Personality Disorder as one of the dramatic-emotional (also called Cluster B) personality disorders. While each of these personality disorders is a distinct diagnosis, they all share a number of overlapping and related symptoms, including problems with emotional expression and difficulty forming stable, healthy relationships. In addition to borderline, the other dramatic-emotional personality disorders are antisocial, histrionic, and narcissistic.

Borderline Personality Disorder is characterized by a persistent pattern of emotional instability, volatile interpersonal relationships, unstable self-image, and self-destructive impulsive behaviors.
