Nearly half of dementia cases in the U.S. may stem from factors that are modifiable either through changes to lifestyle or public policy, according to new research published by AARP, the Alzheimer's Disease Data Initiative (ADDI) and the Institute for Health Metrics and Evaluation (IHME) at the University of Washington. ADDI and IHME are both members of the Brain Health Action Collaborative Advisory Group.
