Personality Disorders

Personality disorders are a group of mental health conditions characterised by persistent and inflexible patterns of thoughts, feelings, and behaviours that impair an individual’s ability to function in their daily life. The Diagnostic and Statistical Manual of Mental Disorders (DSM-5), the standard classification of mental disorders used by mental health professionals, categorises personality disorders into three clusters.

Cluster A: This cluster includes personality disorders characterised by odd or eccentric behaviour, such as Paranoid Personality Disorder, Schizoid Personality Disorder, and Schizotypal Personality Disorder. People with Cluster A personality disorders may have difficulty with social interaction and exhibit suspicious or paranoid thoughts.

Cluster B: This cluster includes personality disorders characterised by dramatic, emotional, or erratic behaviour, such as Borderline Personality Disorder, Narcissistic Personality Disorder, Histrionic Personality Disorder, and Antisocial Personality Disorder. People with Cluster B personality disorders may struggle with relationships and display impulsive and emotionally unstable behaviour.

Cluster C: This cluster includes personality disorders characterised by anxious or fearful behaviour, such as Avoidant Personality Disorder, Dependent Personality Disorder, and Obsessive-Compulsive Personality Disorder. People with Cluster C personality disorders may have difficulty with attachment and may exhibit fearful and avoidant behaviours.
