MAPT and Alzheimer disease: Supplementing the scant literature on the efficacy of rTMS for MCI are three additional studies on rTMS for memory improvement: [1] a controlled cross-over trial in “prodromal AD” [29] (i.e., the participants had mild memory loss and were positive for amyloid and tau AD biomarkers [30]) [2]; a single-session rTMS experiment in aMCI [31]; and [3] a single-session rTMS experiment involving older adults with below-normal memory performance [32].
