What are the risk factors for borderline personality disorder?

Research on the possible causes and risk factors for borderline personality disorder is still at a very early stage. However, scientists generally agree that genetic and environmental factors are likely to be involved.

Studies on twins with borderline personality disorder suggest that the illness is strongly inherited.^16,17 Another study shows that a person can inherit his or her temperament and specific personality traits, particularly impulsiveness and aggression.¹⁸ Scientists are studying genes that help regulate emotions and impulse control for possible links to the disorder.¹⁹

Social or cultural factors may increase the risk for borderline personality disorder. For example, being part of a community or culture in which unstable family relationships are common may increase a person's risk for the disorder.¹ Impulsiveness, poor judgment in lifestyle choices, and other consequences of BPD may lead individuals to risky situations. Adults with borderline personality disorder are considerably more likely to be the victim of violence, including rape and other crimes.
