  1. Brain Age Gap Predicts Progression to Dementia in SCD and MCI

    ✓ Peer-reviewed alzhub usefulness score 45 out of 100. Alzheimer s & Dementia 2025-12-01 Cognitive tests and assessment

    224 subjects progressed to dementia (SCD=38 (9.72%), MCI=186 (50.8%)).

  2. Higher risk of dementia in English older individuals who are overweight or obese

    ✓ Peer-reviewed alzhub usefulness score 67 out of 100. International journal of epidemiology 2020-08-01 Prevention and risk

    Our results suggest that having an increased body weight or abdominal obesity are associated with increased dementia incidence.

  3. BMI and risk of dementia in two million people over two decades: a retrospective cohort study

    ✓ Peer-reviewed alzhub usefulness score 66 out of 100. The lancet. Diabetes & endocrinology 2015-04-09 How common it is

    Our cohort of 1,958,191 people from UK general practices had a median age at baseline of 55 years (IQR 45-66) and a median follow-up of 9·1 years (IQR 6·3-12·6).

  4. Mediterranean diet and Alzheimer disease mortality

    ✓ Peer-reviewed alzhub usefulness score 58 out of 100. Neurology 2007-09-01 Genetics

    Adherence to the Mediterranean diet (MeDi) may affect not only risk for Alzheimer disease (AD) but also subsequent disease course: Higher adherence to the MeDi is associated with lower mortality in AD.
