Schizoaffective disorder is a perplexing mental illness distinguished by a combination of symptoms of a thought disorder or other psychotic symptoms such as hallucinations or delusions (schizophrenia component) and those of a mood disorder (depressive or manic component). The coupling of symptoms from these divergent spectrums makes treating patients who are schizoaffective difficult. Schizoaffective disorder has features of both schizophrenia, including hallucinations, delusions, and distorted thinking, and a mood component, such as depression or mania. This new book brings together leading-edge research in the field.
