APOE Genetics
95–97% of current Alzheimer's cases are driven by lifestyle factors, not genetics. The APOE E4 variant impairs lipid transport in the brain, contributing to amyloid accumulation. Three genes—Presenilin 1, Presenilin 2, and Amyloid Precurso…

95–97% of current Alzheimer's cases are driven by lifestyle factors, not genetics. The APOE E4 variant impairs lipid transport in the brain, contributing to amyloid accumulation. Three genes—Presenilin 1, Presenilin 2, and Amyloid Precursor Protein—are fully deterministic for dementia, guaranteeing early-onset diagnosis. APOE E4 does not guarantee Alzheimer's disease but demands rigorous lifestyle discipline.
