Physical illness diagnosed as psychiatric: patients at special risk

Recent research has further confirmed the significant incidence of undiagnosed physical illness in patients presenting psychiatric symptoms. Such research has generally involved psychiatric inpatient or outpatient populations. As a liaison psychiatrist in a general hospital, the author defines two especially high-risk groups for such missed diagnoses and emphasizes the fact that psychiatric symptoms are not illness specific. An approach to the clinical evaluation of such patients is discussed, mentioning the inherent medicolegal implications.
