Associations between olfactory dysfunction and cognition: a scoping review.

ABSTRACT:

Introduction

Strong evidence suggests that olfactory dysfunction (OD) can predict additional neurocognitive decline in neurodegenerative conditions such as Alzheimer's and Parkinson's diseases. However, research exploring olfaction and cognition in younger populations is limited. The aim of this review is to evaluate cognitive changes among non-elderly adults with non-COVID-19-related OD.

Results

We identified 2878 studies for title and abstract review, with 167 undergoing full text re
