These findings were aslo confirmed by the randomized clinical trial of Galasko et al. [77], which showed that treatment of AD patients for 16 weeks with vitamin E (800 IU/day) plus Vit C (500 mg/day) plus α-lipoic acid (900 mg/day) did not influence cerebrospinal fluid levels of Aβ42, tau and p181tau (widely accepted biomarkers related to amyloid or tau pathology), but decreased F2-isoprostane level (a validated biomarker of oxidative stress). This evidence concerns the gene MAPT and Alzheimer disease.
