Medial temporal lobe‐cortical connectivity is lower in older adults of African ancestry with the ABCA7‐80 risk allele but not in APOE‐ε4 carriers
APOE-ε4 and ABCA7-80 differentially shape MTL-parietal networks in preclinical stages of AD. The observed decrease in connectivity in ABCA7-80 carriers may reflect early dysfunction in neural networks involved in memory and attention. ABCA7-80 may therefore serve as an early marker of neural disruption in older adults of African ancestry, providing valuable insights for genotype-targeted interventions.
