Ten years after hospitalization for borderline personality disorder, 86% of 290 patients had sustained symptom remissions but only 50% had also recovered social and vocational functioning. However, Zanarini et al. (p. 663) also found that once recovery was attained it was likely to be stable. Two-thirds of the patients who were functionally recovered remained so, as did 85% of those with symptom remissions lasting at least 4 years. The editorial by Dr. Michael Stone on p. 618 points out that many of the traits of borderline personality disorder, such as irritability, moodiness, demandingness, manipulativeness, and mercuriality, are ego-syntonic and thus persist after the remission of other symptoms. These traits are more difficult to treat, yet they also account for the continuing psychosocial disability.
