Building a good social life and holding down a job can be tough for people with borderline personality disorder (BPD) even when their symptoms have disappeared. Mary Zanarini from McLean Hospital in Massachusetts followed 290 people with BPD over a decade to see how their condition changed; the participants in the study had all been inpatients at the hospital. 93% of the patients had had at least one 2-year break from BPD symptoms over the course of the study and 86% had had a four-year period without symptoms. However, only about half of the participants achieved 'full recovery' which was defined as a reprieve from symptoms lasting at least two years plus good social and vocational functioning. Of those who did recover about a third later redeveloped symptoms or once again struggled socially, or with their job.
