BPD is thought to result from a combination of genetic, environmental, and social factors. It affects approximately 1–2% of the general population and 20% of psychiatric inpatients.
- Heritability: Up to 69%, as indicated by twin studies, though environmental influences may also play a significant role.
- Childhood abuse and neglect: Around 70% of individuals with BPD have experienced abuse or neglect, including emotional, physical, or sexual abuse, or an unstable family environment.
Complications
BPD can create challenges in completing education, maintaining employment, and engaging in healthy relationships. Risky behaviors such as unsafe sex and reckless driving increase vulnerability to harm.
- Suicide: About 10% of individuals with BPD die by suicide.
- Co-occurring disorders: These include mood disorders (80–96%), anxiety disorders (88%), substance abuse (64%), eating disorders (53%), attention deficit hyperactivity disorder (10–30%), and bipolar disorder (15%).
Borderline Personality Disorder Treatment
No medications are specifically approved for BPD, but certain drug classes like anticonvulsants, antidepressants, anxiolytics, or antipsychotics may be prescribed to manage symptoms.
The mainstay of treatment is psychotherapy, with three primary approaches being:
Transference-Focused Psychotherapy (TFP): Focuses on raising awareness of interpersonal difficulties and self-destructive behaviors.
Mentalization-Based Therapy (MBT): Helps manage emotional dysregulation by promoting an understanding of one’s own and others’ mental states.
Dialectical Behavior Therapy (DBT): Teaches interpersonal skills and mindfulness techniques to regulate emotions and reduce relational conflicts.
