Overview
- Researchers mined MarketScan claims and Vanderbilt EHRs, comparing 10 years of records for 43,508 Alzheimer’s cases and matched controls in MarketScan and 1,320 cases in Vanderbilt.
- More than 70 recurring prediagnostic conditions emerged across mental health, neurologic and sleep, cardiovascular and circulatory, and endocrine and metabolic domains.
- Genetic analyses using Vanderbilt’s BioVU and the UK Biobank linked 19 of these conditions to Alzheimer’s risk variants or to a polygenic risk score.
- The work reinforces hypertension and hypercholesterolemia as midlife risk factors, pointing to prevention opportunities through lifestyle changes or medications.
- An inverse cancer–Alzheimer’s association was replicated across datasets, which investigators are probing for mechanisms as they emphasize these are associations intended to guide targeted research.
