Borderline Personality Disorder: Diagnosis

Diagnosis of borderline personality disorder requires clinical assessment by a qualified mental health professional. Diagnostic criteria include:

  • Intense fear of abandonment
  • A persistently unstable self-image
  • A pattern of unstable relationships veering between extremes of idealization and devaluation
  • Impulsive risky behavior
  • Suicidal or self-harming behavior
  • Frequent mood swings
  • Chronic feelings of emptiness
  • Difficulty controlling anger
  • Paranoid thinking or dissociative symptoms

For a diagnosis, five or more of the criteria must be present, no later than early adulthood.
