Alzheimer disease (AD) is characterized clinically by progressive cognitive decline, and pathologically by the presence in the brain of senile plaques composed primarily of amyloid-beta peptide and neurofibrillary tangles containing hyperphosphorylated tau protein. Here we investigated the effects ofa naturally occurring amide of ethanolamine and palmitic acid (PEA), abundant in the CNS to contrast the AD phenotype in triple transgene (PS1, APP and Tau) mice model, by in vivo 1H MRI and MRS and histology. Our data indicate that PEA treatment affects brain metabolism as a function of age and that PEA rescues altered molecular pathways that can mimic some traits of AD
