Dietary Patterns and Dementia Risk: Insights from a Large UK Biobank Cohort Study

Background and Disease Burden

Dementia represents a growing global health challenge, with substantial disability and dependency burdens among older adults. Despite advances in identifying modifiable risk factors such as physical inactivity and cardiovascular health, diet has often been sidelined due to inconsistent evidence linking specific dietary patterns to dementia risk. Given the increasing prevalence of dementia worldwide and limited therapeutic options, prevention strategies—including nutritional modifications—have garnered interest. This study specifically evaluates the associations of four established dietary indices with the incidence of all-cause and cause-specific dementia within a large prospective cohort.
