Syncope in elderly patients has an elusive underlying cause in up to 50% of cases, despite evaluations emphasizing cardiovascular and neurologic components.
Syncope in the elderly is multifactorial and often remains unexplained in up to half of patients despite cardiovascular and neurologic evaluation.

Highlights diagnostic gaps in elderly syncope; leaves open the need for refined etiologic research beyond standard evaluations.
The elderly are at increased risk for syncope not only because of physiologic changes due to aging but also because they have a higher incidence of chronic illness and use a greater number of medications that may cause orthostatic hypotension. Although evaluation should emphasize cardiovascular and neurologic components, the cause may remain elusive in as many as 50% of patients.
