Step-by-step explanation:
The key characteristics of Schizotypal Personality Disorder are odd beliefs or magical thinking, eccentric behavior, and discomfort with close relationships. This personality disorder is categorized by symptoms that are less severe but similar to schizophrenia, including distorted perception of reality and peculiar behaviors. People with Schizotypal Personality Disorder may exhibit speech patterns that are unusual or digressive and tend to be suspicious or paranoid about others. They might also experience social anxiety that does not diminish with familiarity, leading to significant social withdrawal. Unlike schizophrenia, which may include more severe psychotic symptoms such as hallucinations and delusions, Schizotypal Personality Disorder primarily pertains to discomfort in close relationships, cognitive or perceptual distortions, and eccentricities in behavior.
