Personality disorders (PD) are often grouped into three clusters based on their characteristics:
1. Cluster A (Odd or Eccentric disorders):
• Paranoid PD: Distrust and suspicion of others.
• Schizoid PD: Social detachment and limited emotional expression.
• Schizotypal PD: Odd beliefs, eccentric behavior, and discomfort in close relationships.
2. Cluster B (Dramatic, Emotional, or Erratic disorders):
• Antisocial PD: Disregard for the rights of others, often with manipulative or criminal behavior.
• Borderline PD: Instability in relationships, self-image, and emotions, often leading to impulsive actions.
• Histrioni. PD: Excessive emotionality and attention-seeking behavior.
• Narcissistic PD: Grandiosity, need for admiration, and lack of empathy for others.
3. Cluster C (Anxious or Fearful disorders):
• Avoidant PD: Social inhibition, feelings of inadequacy, and hypersensitivity to criticism.
• Dependent PD: Excessive need to be taken care of, leading to submissive and clinging behaviors.
• Obsessive-Compulsive PD: Preoccupation with orderliness, perfectionism, and control.
Each cluster represents a different set of behavioral patterns, with Cluster A characterized by odd or eccentric behaviors, Cluster B by dramatic or emotional behaviors, and Cluster C by anxious or fearful behaviors.
