Anxiety comorbidity in schizophrenia.
Diagnostic and treatment hierarchical reductionisms have led to an oversight of anxiety syndromes in schizophrenia. Nevertheless, recent data have indicated that anxiety can be a significant source of morbidity in this patient group. This paper reviews current knowledge concerning anxiety comorbidity in schizophrenia, its epidemiology, course, and treatment. A computerized search of the literature published from 1966 to July 2012 was conducted on Medline. Comorbid anxiety disorders are present in 38.3% of subjects with schizophrenia spectrum disorders. The most common anxiety disorder is social phobia followed by post-traumatic stress disorder and obsessive compulsive disorder. The presence and severity of symptoms of anxiety are associated with more severe clinical features and poorer outcomes. Available literature on the treatment consists primarily of case reports and open trials. Fragments of data support the notion of treating these anxiety states and syndromes as co-occurring clinical conditions with adjunctive medications and psychosocial interventions. However, additional work remains to be done on this issue before firm conclusions can be drawn.
