Associated Features and Disorders
Individuals with Schizotypal Personality Disorder often seek treatment for the associated symptoms of anxiety, depression, or other dysphoric affects rather than for the personality disorder features per se. Particularly in response to stress, individuals with this disorder may experience transient psychotic episodes (lasting minutes to hours), although they usually are insufficient in duration to warrant an additional diagnosis such as Brief Psychotic Disorder or Schizophreniform Disorder. In some cases, clinically significant psychotic symptoms may develop that meet criteria for Brief Psychotic Disorder, Schizophreniform Disorder, Delusional Disorder, or Schizophrenia. Over half may have a history of at least one Major Depressive Episode. From 30% to 50% of individuals diagnosed with this disorder have a concurrent diagnosis of Major Depressive Disorder when admitted to a clinical setting. There is considerable co-occurrence with Schizoid, Paranoid, Avoidant, and Borderline Personality Disorders. (p. 642)
