Abstract

Olfactory deficits have been reported to be associated with neurological disorders such as Alzheimer's disease (AD), idiopathic Parkinson's disease and several other types of dementia. There has been increasing interest in early and severe olfactory impairment related to neurodegenerative disorders. AD is the most common type of dementia, accounting for approximately 60-80% of cases. The purpose of this study was to analyze the relationship between olfactory and cognitive dysfunction in AD and to explore whether olfactory testing, as part of a neurocognitive evaluation, could be a useful screening and prognostic tool for AD.
