What causes borderline personality disorder?

Healthcare providers believe BPD results from a combination of factors, including:

• Childhood abuse and trauma: Up to 70% of people with BPD have experienced sexual, emotional or physical abuse as a child. Maternal separation, poor maternal attachment, inappropriate family boundaries and parental substance use disorder are also associated with BPD.
• Genetics: Studies show that borderline personality disorder runs in families. If you have a family history of BPD, you’re more likely — but not guaranteed — to develop the condition.
• Brain changes: In people with BPD, the parts of their brain that control emotion and behavior don’t communicate properly. These problems affect the way their brain works.
