Which of the following disorders is categorized under Cluster A personality disorders?

Schizotypal Personality Disorder is classified under Cluster A personality disorders in the DSM-5, which are characterized by odd or eccentric behaviors and thinking. Individuals with schizotypal personality disorder often exhibit patterns of social and interpersonal deficits, as well as cognitive or perceptual distortions and eccentricities in their behavior. Symptoms might include odd beliefs or magical thinking, unusual perceptions, and social anxiety stemming from a lack of comfort with close relationships.

Cluster A personality disorders include not only schizotypal but also paranoid and schizoid personality disorders. These disorders reflect a more withdrawn and eccentric approach to social interactions, contrasting with the more emotional and erratic presentations observed in Cluster B disorders, like Antisocial or Borderline Personality Disorder, and the more dramatic self-focus seen in Cluster C disorders. Understanding the characteristics that define Cluster A can aid in accurate diagnosis and treatment planning in clinical practice.
