Polygenic Risk Scores in Alzheimer’s Disease: A Cross-Scale View from Genes to Brain and Behavior
Alzheimer’s disease (AD) is a genetically complex disorder in which inherited susceptibility is distributed across rare high-impact variants, the apolipoprotein E (APOE) locus, and a broad polygenic background of common risk alleles. Polygenic risk scores (PRSs) provide a quantitative framework for summarizing this dis...
