Personality Disorder Treatment

Personality disorders are complex mental health conditions that affect how individuals think, feel, and relate to others. These patterns are often long-standing and can influence relationships, self-image, and daily functioning. While they can be challenging to navigate, effective treatment can help individuals build healthier coping strategies, improve interpersonal connections, and create more stability in their lives.

About Personality Disorders

What are personality disorders?

Personality disorders are a group of mental health conditions characterized by long-term, inflexible patterns of thinking, feeling, behaving, and relating to others that deviate significantly from cultural expectations. These patterns are pervasive (affecting multiple areas of life), begin in adolescence or early adulthood, cause significant distress or problems in functioning (e.g., relationships, work, social activities), and are often rigid and hard to change without treatment.


Unlike depression, which is primarily a mood disorder with episodes of low mood, hopelessness, and loss of interest (often triggered by life events or biological factors and can improve with time or treatment), personality disorders involve enduring traits that shape how a person views themselves and the world. Depression can sometimes co-occur with personality disorders (e.g., someone with borderline personality disorder may experience intense depressive episodes), but the core issue in personality disorders is maladaptive personality structure, not just mood imbalance.

Types of personality disorders

The DSM-5-TR organizes the 10 recognized personality disorders into three clusters based on shared features:

  • Cluster A (odd or eccentric behaviors):

  • Paranoid personality disorder

  • Schizoid personality disorder

  • Schizotypal personality disorder

  • Cluster B (dramatic, emotional, or erratic behaviors):

  • Antisocial personality disorder

  • Borderline personality disorder (often involves intense emotions, unstable relationships, fear of abandonment, and impulsivity)

  • Histrionic personality disorder

  • Narcissistic personality disorder

  • Cluster C (anxious or fearful behaviors):

  • Avoidant personality disorder

  • Dependent personality disorder

  • Obsessive-compulsive personality disorder (note: this differs from OCD, which is an anxiety-related disorder)

Symptoms of personality disorders

Symptoms vary by type but generally include rigid, maladaptive patterns in at least two areas:

  • Thinking about oneself and others (e.g., distorted self-image, mistrust, or grandiosity)
  • Emotional responses (e.g., intense or inappropriate emotions, chronic emptiness)
  • Interpersonal relationships (e.g., unstable, conflicted, or exploitative)
  • Impulse control or behavior (e.g., impulsivity, avoidance, or rigidity)

These patterns cause ongoing problems and distress, often leading to difficulties adapting to change or stress.

Causes of personality disorders

The exact causes are not fully known, but they likely involve a combination of:

  • Genetics (family history increases risk)
  • Early life experiences (e.g., childhood trauma, abuse, neglect, or unstable environments)
  • Environmental factors (e.g., cultural influences or brain development)

They are thought to develop from interactions between biology and environment, often starting in teen or early adult years.

Treatment for personality disorders

Treatment usually focuses on psychotherapy (talk therapy) as the mainstay, since these are enduring patterns rather than temporary episodes. Effective approaches include:

  • Dialectical behavior therapy (DBT) — especially for borderline personality disorder
  • Cognitive behavioral therapy (CBT)
  • Schema therapy
  • Psychodynamic therapy
  • Group or family therapy

Medications may help manage co-occurring symptoms (e.g., antidepressants for depression, mood stabilizers for impulsivity), but they don’t “cure” the personality disorder itself. Early recognition and consistent therapy can improve functioning, relationships, and quality of life significantly—though change is often.
