What Is Personality Disorder (PD)?
A personality disorder (PD) is a type of mental health condition that affects how a person thinks, feels and behaves, making it challenging to relate to others and navigate everyday life. People with PD often have long-standing patterns of thinking and behaving that differ significantly from societal expectations, causing distress and difficulties in relationships, work and social settings.
In the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition), personality disorders are grouped into three clusters based on similar characteristics:
- Cluster A (Odd or eccentric): Includes Paranoid, Schizoid and Schizotypal Personality Disorders.
- Cluster B (Dramatic or emotional): Includes Borderline, Narcissistic, Histrionic and Antisocial Personality Disorders.
- Cluster C (Anxious or fearful): Includes Avoidant, Dependent and Obsessive-Compulsive Personality Disorders.
Each type has unique features, but all involve persistent difficulties in managing emotions, relationships and self-image.
