"Borderline personality disorder (BPD) is defined by the Diagnostic and Statistical Manual for Mental Disorders (DSM-IV) (1) as a categorical disorder with 9 criteria including affective instability, unstable interpersonal relationships, impulsivity, identity problems (IP), and transient cognitive distortion. Given that only five of these criteria must be present, there are more than 250 ways to fulfill a BPD diagnosis. "
