Alzheimer’s disease (AD) is one of the most common causes for the development of Dementia in the elderly. In past two decades there has been abundant research in pathogenesis of AD and possible prevention and treatment. Research evidences have suggested the major role of oxidative stress in the pathogenesis of AD. Sources of this stress are disruption of homeostasis of metals, mitochondrial dysfunction, genetic mutations, β Amyloid accumulation, hyperphosphorylation of tau and inflammation. Oxidative damage found in AD occurs as a result of advanced glycation end products, nitration, lipid peroxidation adduction products, carbonyl modified neurofilament protein and free carbonyls. All the products, discussed above have been considered as blood biomarkers for early diagnosis of AD. Various antioxidant therapies have been identified and studied for prevention and possible treatment of AD, based on role of oxidative stress in pathogenesis of AD. In this review we briefly discuss about the sources of oxidative stress and pathogenesis of AD, along with various newer and older antioxidant therapeutic options.
