This spectrum includes schizophrenia, schizophreniform disorder, schizotypal personality disorder, delusional disorder, schizoaffective disorder, and unspecified schizophrenia spectrum and other psychotic disorders, among others. Schizophrenia is a disorder that includes two or more of the following symptoms: delusions, hallucinations, disorganized speech, grossly disorganized or catatonic behavior, and negative symptoms, whereas delusional disorder is characterized by at least 1month of delusions but no other psychotic symptoms. On the other hand, schizotypal personality disorder is characterized by a pervasive pattern of social and interpersonal deficits including reduced capacity for close relationships, cognitive or perceptual distortions, and eccentricities of behavior usually beginning in early adulthood but in some cases, it becomes apparent in childhood and adolescence.
