Creatine treatment started at 6, 8, and 10 weeks of age, analogous to early, middle, and late stages of human HD, significantly extended survival at both the 6- and 8-week starting points. Significantly improved motor performance was present in both the 6- and 8-week treatment paradigms, while reduced body weight loss was only observed in creatine-supplemented R6/2 mice started at 6 weeks." (Dedeoglu, et al., 2003) Specifically it is stated that the "...Neuropathological sequelae of gross brain and neuronal atrophy and huntington aggregates were delayed in creatine-treated R6/2 mice started at 6 weeks. We show significantly reduced brain levels of both creatine and ATP in R6/2 mice, consistent with a bioenergetic defect. Oral creatine supplementation significantly increased brain concentrations of creatine and ATP to wild-type control levels, exerting a neuroprotective effect. These findings have important therapeutic implications, suggesting that creatine therapy initiated after diagnosis may provide significant clinical benefits to...
