Abstract

Fifty cases of orthostatic hypotension in the elderly are analysed. Three main modes of presentation were identified: (1) falls or mobility problems; (2) mental confusion or dementia; or (3) predominantly cardiac symptoms. Selected case histories are given to illustrate diagnostic difficulties. Medication was responsible for orthostatic hypotension in 66% of patients and striking examples of polypharmacy were encountered. However, 34% of cases were not iatrogenic. Only 14% of patients had overtly postural symptoms. A high index of suspicion is needed to diagnose orthostatic hypotension in the elderly and the condition is often overlooked. The paper provides useful diagnostic clues for clinicians.
