Synopsis

Glutathione (GSH) is a brain marker for oxidative stress, which has previously been associated with brain amyloidosis and memory decline. However, to date no study has examined the link between GSH and beta-amyloid in a large cohort of elderly participants. Using simultaneous PET/MRS, we assessed amyloid deposition with amyloid-PET and GSH with MEGAPRESS, in a cohort of 134 healthy elderly and 46 mild cognitively impaired participants. GSH declined with age and showed sex differences, but no significant association between GSH and amyloid status was observed
