Structural brain changes appear years before the onset of Alzheimer's disease, the leading cause of dementia late in life. Determining risk factors for such presymptomatic brain changes may assist in identifying candidates for future prevention treatment trials. In addition to the e4 allele of the apolipoprotein E gene (APOE-4), the major known genetic risk factor, a family history of Alzheimer's disease also increases the risk to develop the disease, reflecting yet unidentified genetic and, perhaps, nongenetic risks. The authors investigated the influence of APOE-4 genotype and family history risks on cortical thickness in medial temporal lobe subregions among volunteers without cognitive impairment.
