Risk factors

By Mayo Clinic staff

Personality forms during childhood. It's shaped by both inherited tendencies and environmental factors, or your experiences during childhood. Some factors related to personality development can increase your risk of developing borderline personality disorder. These include:

  • Hereditary predisposition. You may be at a higher risk if a close family member — a mother, father or sibling — has the disorder.
  • Childhood abuse. Many people with the disorder report being sexually or physically abused during childhood.
  • Neglect. Some people with the disorder describe severe deprivation, neglect and abandonment during childhood.

Also, borderline personality disorder is more common in women than in men.
