Olfactory Loss and Dysfunction in Dementia and Cognitive Decline

This chapter starts by highlighting the experiences of people living with olfactory dysfunction, people living with both dementia and olfactory dysfunction, and of caregivers. There follows a brief outline of the anatomy of olfactory function, then sections on evidence for olfactory dysfunction and its general impact, the association between olfactory dysfunction and mild cognitive impairment/cognitive change and a range of different aetiologies of dementia. This is followed by further discussion about dementia-related impact, some study limitations to date and some helpful suggestions and a contact list for further information/advice.
