10 Personality Disorders Explained: A Complete Guide to Mental Health Types (2024)

Understanding personality disorders helps people recognize and address mental health challenges that affect millions worldwide. These complex conditions influence how individuals think, behave, and relate to others, often causing significant disruption in their daily lives and relationships.

The Diagnostic and Statistical Manual of Mental Disorders (DSM-5) identifies ten distinct personality disorders grouped into three clusters based on similar characteristics. While each disorder has unique traits and symptoms, they all share common features: long-term patterns of behavior that differ significantly from cultural expectations and cause persistent problems in various aspects of life. Recognizing these disorders is crucial for adequately diagnosing, treating, and supporting those affected.
