Treatment plans for patients with personality disorders often include psychotherapy -- one-on-one, family, couples or group -- and medications to relieve symptoms of anxiety and altered perceptions.

Psychotherapy may be helpful in teaching patients the underlying causes and triggers of their symptoms, reducing unwanted behavior patterns and improving social skills, coping skills and self-esteem.
