Personality disorders are intractable and, as such, not comparable to addiction. Their long-term prognosis can be good for the very short run; long-term is always "back to square one"--if suicide doesn't intervene. But meds, at times, can bring relief and safety, but only for a short period. Compliance is a huge problem with personality disorders.
If you tested of govt employees, 95% if them would have some kind of personality disorder. And I’m not joking, either.
