ABSTRACT
The extent of psychiatric comorbidity in schizophrenia is often not
appreciated, in part this is because of a heritage of an essentially hierar-
chical approach to psychiatric diagnosis, where schizophrenia trumps
depression and anxiety. However, the recognition of depressive and
anxiety symptoms in people with schizophrenia is important, as these
symptoms are common, tend to worsen the longitudinal course of
illness, and can result in secondary morbidity and suicide. This chapter
provides a brief overview of depression and selected anxiety disorders
(social anxiety and obsessive-compulsive disorder) in schizophrenia.
