Predictive value of olfactory impairment for cognitive decline among cognitively normal adults
Abstract
Dementia affects over 47 million people worldwide. Olfactory impairment (OI) is a well‐established predictive marker of conversion to dementia among those with mild cognitive impairment. This systematic review aims to describe the predictive value of OI for future cognitive decline among cognitively normal adults.
