Abstract

The dexamethasone suppression test (DST) was performed on 26 elderly male outpatients in a geriatric medical clinic. Patients with depression were excluded. All patients had two or more medical diagnoses. Fourteen patients also met DSM‐IM criteria for dementia. No patient had an abnormal DST result. The authors suggest that neither chronic medical illness nor dementia causes false‐positive DST results in this patient population in an outpatient setting, and discuss the findings in relation to previous reports.
