Major depression and subsyndromal depression are common in older persons. Unrecognized depression results in increased morbidity and mortality. Recognition of depression is challenging due to patient- and clinician-related factors. Diagnosis in the older person is confounded by medical comorbidities as well as normal changes. Depression in older adults manifests differently: somatic complaints, nonspecific symptoms, and cognitive difficulties are common, as are behavioural changes, including apathy and irritability. Anhedonia better reflects depression, since depressed mood is often denied by the older person. Depression is likely to be missed if only typical symptoms are sought. Appropriate recognition can lead to improved treatment and outcomes.
Key words: depression, older adult, diagnosis, recognition, management.
