Treatments for Personality Disorders


During psychotherapy with a mental health professional, people can learn about their condition and talk about moods, feelings, thoughts, and behaviors. They can learn to cope with stress and manage the disorder.

Psychotherapy may be provided in individual sessions, group therapy, or sessions that include family or even friends. There are several types of psychotherapy — a mental health professional can determine which one is best for each person.

Social Skills Training

During this training they can use the insight and knowledge they gain to learn healthy ways to manage their symptoms and reduce behaviors that interfere with functioning and relationships.

Schema Therapy

Schema therapy is a newer type of therapy that combines elements of cognitive behavioral therapy (CBT), psychoanalysis, attachment theory, and emotion-focused therapy, among others. In schema therapy, you’ll work with a therapist to uncover and understand your schemas, sometimes called early maladaptive schemas. Schema therapy aims to teach you how to ensure your emotional needs are met in a healthy way that doesn’t cause distress.

Family Therapy

Provides support and education to families dealing with a family member who has a personality disorder.

Mentalization-Based Therapy (MBT)

Mentalizing, or the ability to focus on and differentiate between your own emotional state of mind and that of others, and understand how one’s mental state influences behavior, is a normal cognitive function that is limited in those with some personality disorders. Enhancement of mentalization and improved emotional regulation are at the core of MBT treatment.


There are no medications specifically approved by the Food and Drug Administration (FDA) to treat personality disorders. However, several types of psychiatric medications may help with various personality disorder symptoms.

  • Antidepressants. Antidepressants may be useful for a depressed mood, anger, impulsivity, irritability, or hopelessness, which may be associated with personality disorders.
  • Mood stabilizers. As their name suggests, mood stabilizers can help even out mood swings or reduce irritability, impulsivity, and aggression.
  • Antipsychotic medications. Also called neuroleptics, these may be helpful if symptoms include losing touch with reality (psychosis) or in some cases if there are anxiety or anger problems.
  • Anti-anxiety medications. These may help if someone has anxiety, agitation, or insomnia. But in some cases, they can increase impulsive behavior, so they're avoided in certain types of personality disorders.
