SEATTLE — Today, AARP, the Alzheimer’s Disease Data Initiative (AD Data Initiative), and the Institute for Health Metrics and Evaluation (IHME) at the University of Washington announced the Dementia Risk Reduction Project, a new collaboration to study how factors -- air pollution, alcohol use, depression, diabetes, high body mass index, hearing loss, hypertension, low education, physical inactivity, social isolation, smoking, and traumatic brain injury—vary by state and their correlation to dementia. The research will explore causal links between each factor and dementia, providing valuable information for both consumers and policymakers to address dementia risks in their communities.
