The result of biochemical actions that help to shield neurons from damage by slowing free radical activity and oxidation. Natural substances such as vitamins and other nutrients contain antioxidants. Antioxidants bind with free radicals, the waste by-products of metabolism, to prevent them from forming unstable molecular structures that cause cumulative damage to neurons and other cells. Some medications, such as monoamine oxidase inhibitor (maoi) medications, also have neuro-protective effects by limiting the formation of free radicals.
