Masticatory Function, Sex, and Risk of Dementia Among Older Adults: A Population-Based Cohort Study.

Background

A decline in masticatory function may indicate brain dysfunction related to dementia, but the relationship between masticatory function and dementia risk remains unclear. This study aimed to investigate whether masticatory function is associated with the risk of cognitive decline and dementia.
