What Are Personality Disorders?
A personality disorder involves rigid, unhealthy patterns of behavior and inner experience that affect a person’s sense of self, emotional responses, and how they relate to others.
To be diagnosed, these patterns must:
-
Be long-lasting (typically beginning in adolescence or early adulthood)
-
Affect multiple areas of life (relationships, work, thinking)
-
Cause significant distress or impairment
Types of Personality Disorders
The American Psychiatric Association groups personality disorders into three clusters based on similar traits:
Cluster A – Odd or Eccentric Behavior
-
Paranoid Personality Disorder – Distrust and suspicion of others
-
Schizoid Personality Disorder – Detachment from relationships, limited emotional expression
-
Schizotypal Personality Disorder – Odd beliefs or behavior, social anxiety, distorted thinking
Cluster B – Dramatic, Emotional, or Erratic Behavior
-
Antisocial Personality Disorder – Disregard for the rights of others, deceitful or manipulative behavior
-
Borderline Personality Disorder – Intense emotions, unstable relationships, fear of abandonment
-
Histrionic Personality Disorder – Excessive attention-seeking and emotional expression
-
Narcissistic Personality Disorder – Grandiosity, need for admiration, lack of empathy
Cluster C – Anxious or Fearful Behavior
-
Avoidant Personality Disorder – Extreme social inhibition, feelings of inadequacy
-
Dependent Personality Disorder – Excessive need to be taken care of, fear of separation
-
Obsessive-Compulsive Personality Disorder – Preoccupation with order, perfectionism, and control (not to be confused with OCD)
Causes and Risk Factors
The exact causes of personality disorders are unknown, but a combination of genetics, early childhood experiences, and environmental factors are believed to play a role. Contributing factors may include:
-
Family history of mental illness
-
Childhood trauma or abuse
-
Neglect or unstable home life
-
Brain structure or chemistry differences
Diagnosis and Treatment
Diagnosing a personality disorder requires a comprehensive psychological evaluation by a licensed mental health professional. Because symptoms often overlap with other conditions, diagnosis can take time and careful observation.
Effective Treatments May Include:
-
Psychotherapy (Talk Therapy): The most common and effective treatment. Dialectical Behavior Therapy (DBT) and Cognitive Behavioral Therapy (CBT) are particularly useful for certain disorders.
-
Medication: There are no specific medications for personality disorders, but symptoms such as depression or anxiety may be treated with antidepressants or mood stabilizers.
-
Support Groups: Can provide community, education, and emotional support.
Living with a Personality Disorder
Having a personality disorder doesn’t mean someone is “broken” or can’t live a full and meaningful life. With the right support and treatment, many people are able to build healthier relationships, regulate emotions, and develop better coping skills.
