Antioxidant vitamins are believed to reduce oxidative damage to the brain, thereby protecting cognitive function. Animal research out of Perth in Western Australia showed oxidative mechanisms related to neuronal cell death might play a major role in aging, and antioxidants can protect against neurodegeneration. Human research in Italy also showed a link between cognitive decline and antioxidant status: Elderly subjects with mild cognitive impairment or Alzheimer’s disease showed lower plasma antioxidant levels compared to healthy controls.
