Excerpt

Schizophrenia is the prototypical psychotic disorder. Not only is it the most common psychosis, but schizophrenia tends to involve abnormalities in all five of the emphasized symptom domains: hallucinations, delusions, disorganized thinking (speech), grossly disorganized or abnormal motor behavior (including catatonia), and negative symptoms. Like the DSM-5 neurodevelopmental disorders, schizophrenia is viewed as a neuropsychiatric disorder with complex genetics and a clinical course that tends to begin during a predictable stage of development. Whereas the neurodevelopmental disorders tend to begin during childhood, symptoms of schizophrenia tend to reliably develop during late adolescence and early adulthood.
