Age-dependent effect of Alzheimer's risk variant of CLU on EEG alpha rhythm in non-demented adults.

ABSTRACT: Polymorphism in the genomic region harboring the CLU gene (rs11136000) has been associated with the risk for Alzheimer's disease (AD). CLU C allele is assumed to confer risk for AD and the allele T may have a protective effect. We investigated the influence of the AD-associated CLU genotype on a common neurophysiological trait of brain activity (resting-state alpha-rhythm activity) in non-demented adults and elucidated whether this influence is modified over the course of aging. We examined quantitative electroencephalography (EEG) in a cohort of non-demented individuals (age range 20-80) divided into young (age range 20-50) and old (age range 51-80) cohorts and stratified by CLU polymorphism. To rule out the effect of the apolipoprotein E (ApoE) genotype on EEG characteristics, only subje
