Description
Banafsheh Mohajerin, Parham Mohammadi, and Richard Howard published this study in 2026. Borderline personality disorder is much debated, partly because it bundles such varied problems. The team asked how the picture changes when it appears with other disorders. They compared three groups: patients with it alone, and patients who also had antisocial or narcissistic disorder. Measures covered symptom patterns, emotional control, suicidality, and identity problems.
Network analysis showed the same overall symptom structure in all three groups. What changed was which symptoms stood out. It alone was marked by identity and relationship problems, with the highest suicidality. The antisocial pairing showed the worst emotional dysregulation, impulsiveness, and anger, plus the most severe symptoms overall. The narcissistic pairing sat in between. The authors argue treatment should fit the pairing: care for identity issues when it stands alone, and behavior control when it comes with antisocial traits.
