Answer

The symptoms of schizophrenia may be divided into the following 4 domains:

  • Positive symptoms - Psychotic symptoms, such as hallucinations, which are usually auditory; delusions; and disorganized speech and behavior

  • Negative symptoms - Decrease in emotional range, poverty of speech, and loss of interests and drive; the person with schizophrenia has tremendous inertia

  • Cognitive symptoms - Neurocognitive deficits (eg, deficits in working memory and attention and in executive functions, such as the ability to organize and abstract); patients also find it difficult to understand nuances and subtleties of interpersonal cues and relationships

  • Mood symptoms - Patients often seem cheerful or sad in a way that is difficult to understand; they often are depressed
