Falls preceded or not by fainting and fainting followed or not by a fa
ll are common, and often serious, in the elderly and must be considere
d as an emergency and hence properly investigated, not only in order t
o seek possible consequences, in particular skeletal, but also regardi
ng etiology. This requires a history, physical examination and investi
gations, simple in most cases. Difficulties are increased by the frequ
ency of multiple mechanisms, within which particular attention must be
paid to iatrogenic pathology.
