In one study by Beydoun et al., it was found that even though APOE4(+) status (i.e., any ε4 allele) predicted dementia significantly (hazard ratio [HR] = 2.89; 95% confidence interval [CI], 1.93–4.33), with nonsignificant sex differences, women had significantly stronger positive associations than men between APOE4(+) status and impairment or decline on the California Verbal Learning Test (CVLT; delayed recall and List A total recall) and on Verbal Fluency Test-Categories [5]. Here, APOE is linked to dementia.
