While the evidence of an association between the apolipoprotein E (APOE) *E4 allele and Alzheimer's disease is very strong, the effect of the *E4 allele on cognitive decline in the general population is more equivocal. A cross-sectional study on the lifespan effects of the *E4 allele 1 failed to find any effect of the *E4 allele on cognitive performance at ages 20-24, 40-44 or 60-64 years.
