Utility of olfactory identification test for screening of cognitive dysfunction in community-dwelling older adults.

ABSTRACT:

Background

There is a need for a large-scale screening test that can be used to detect dementia in older individuals at an early stage. Olfactory identification deficits have been shown to occur in the early stages of dementia, indicating their usefulness in screening tests.
