It was suggested that in contrast to the E4 allele, the E2 allele of the apolipoprotein E gene (APOE"2) has a protective effect for late-onset Alzheimer's disease and early-onset Alzheimer's disease (EOAD). We studied the role of the APOE\*2 allele in the pathogenesis of EOAD in a Dutch population-b

Abstract
We investigated the association between apolipoprotein E (APOE) alleles and genotypes and Parkinson disease (PD) in 229 unrelated Mexican Mestizo PD patients and 229 controls. Results showed that both APOE‐ε4 allele and APOE ε4/ε3 genotype are associated with PD (OR = 1.736, P = 0.011; OR = 1.688, P = 0.019, respectively). Mean age at onset of PD was not associated to any APOE allele or genotype, but was significantly earlier in familial PD when compared to sporadic cases (P = 0.025). © 2006 Movement Disorder Society

## Objectives: The aim of this study was to examine whether the apoe epsilon 4 allele also confers a risk for the cognitive impairment in normal aging. ## Methods: We administered all the eight neuropsychological tests from the cerad neuropsychological battery to the cvd-free, community-dwelling
