In a study, the FKBP5 rs1360780 and FKBP5 promoter methylation status was combined with EEG parameters in Alzheimer’s disease patients [91], while, in another study, EEG was used to explore the contribution of MR gene variants in habit learning under stress [92]. This evidence concerns the gene FKBP5 and early-onset autosomal dominant Alzheimer disease.
