​Symptoms and Signs – Differential Diagnosis of Borderline Personality Disorder

​Symptoms and Signs – Differential Diagnosis of  Borderline Personality Disorder
• Substance abuse or dependence: often induces impulsive, emotionally labile behavior.
• Post-traumatic stress disorder (PTSD): individuals with BPD often have history of trauma but do not avoid the feared stimulus or reexperience the trauma, as do individuals with PTSD.
• Mild cases of schizophrenia may superficially resemble BPD.
• Histrionic and narcissistic personality disorders share some common features.
• Dysthymia and other depressive disorders: require a stability of affective symptoms not seen in BPD.
• Bipolar disorder: mood changes in BPD are often triggered by stressors and are less sustained than in bipolar disorder.
