The tendency of the borderline patients to show symptom recovery sooner than resolution of what Zanarini et al. (4) have called "temperamental" aspects (intense anger, abandonment concerns) is quite in keeping with the results of these other investigations. Certain symptoms of borderline personality disorder—self-mutilation, suicide gestures and attempts, impulsive acts like shoplifting and careless sexual encounters—are easier to remediate with medication or psychotherapy, or a combination of the two; good results often become discernible within a year or two (5). Conceptually, borderline personality disorder is really an admixture of symptoms, true personality traits, and cognitive peculiarities, such as identity disturbance. Personality traits are largely ego-syntonic and enduring, however unwelcome and problematical they may be (e.g., introversion, extraversion, sociability, hostility, generosity, stinginess). It is no surprise that some of the traits typical of borderline patients—irritability, moodiness, demandingness, manipulativeness, mercuriality—persist long after the symptoms of the disorder have abated. In an important cautionary note from an earlier paper, however, Zanarini et al. (6) mention that substance abuse represents a symptom that does not abate so quickly and has more ominous prognostic qualities, associated as it is with a strong tendency for failure of remission in borderline personality disorder and with suicidality.
