Which personality disorders are included in Cluster A?

Cluster A personality disorders are characterized by odd or eccentric behavior and include three specific disorders: Schizoid, Schizotypal, and Paranoid Personality Disorders.

Schizoid Personality Disorder involves a pervasive pattern of detachment from social relationships and a restricted range of emotional expression. Individuals with this disorder often appear indifferent to social relationships and may be perceived as loners.

Schizotypal Personality Disorder is marked by social and interpersonal deficits, along with acute discomfort in close relationships, cognitive or perceptual distortions, and eccentric behavior. People with schizotypal traits may exhibit odd beliefs, unusual perceptions, or behaviors and have strange or eccentric speech.

Paranoid Personality Disorder is characterized by a pervasive distrust and suspiciousness of others, leading individuals to interpret their motives as malevolent. Those with this disorder often harbor unjustified doubts about the loyalty or trustworthiness of friends and family.

These disorders stand out in Cluster A due to their unique presentation of social withdrawal, eccentric thoughts, and pervasive distrust, distinguishing them from the disorders found in the other clusters.
