Evidence Scores for Dementia Risk Factors
High blood sugar, hearing loss, and fewer years of education show the strongest evidence of a link to dementia
A risk factor's burden-of-proof evidence score reflects the strength of the evidence for association, based on the magnitude of the link between the risk and dementia and the consistency of available evidence among studies. A negative score indicates that evidence does not establish a significant relationship. Alcohol’s effect varies by consumption level: weakly protective at low to moderate intake, harmful at high levels.
