Summary

This systematic review examines the relationship between adherence to Mediterranean and Nordic dietary patterns and risk of Alzheimer's disease and dementia. The authors synthesise peer-reviewed evidence to evaluate whether dietary intake and specific diet quality metrics associate with cognitive decline and dementia outcomes. The review contributes to understanding how food-based dietary patterns, rather than isolated nutrients, may support cognitive health in ageing populations.

UK applicability

Findings are relevant to UK public health messaging on diet and cognitive ageing, particularly given the rising prevalence of dementia in ageing populations. Applicability depends on whether Mediterranean and Nordic dietary patterns are culturally and economically accessible within UK food environments and healthcare contexts.

Key measures

Dietary adherence scores (Mediterranean Diet Score, Nordic Diet Score), cognitive outcomes (Mini-Cog, MMSE, or similar), dementia incidence and prevalence, nutritional biomarkers

Outcomes reported

The study systematically reviewed evidence on dietary intake patterns, particularly Mediterranean and Nordic diet adherence, in relation to Alzheimer's disease and dementia prevalence, incidence, and cognitive outcomes. The review synthesised findings on how specific dietary patterns and nutrient profiles associate with dementia risk and progression.
