Chronological Primacy of Oxidative-Induced Neuronal Damage in the Pathogenesis of Alzheimer's Disease

Abstract

Alzheimer’s disease (AD) is associated with hallmark pathologies including extracellular Aβ protein deposition in extracellular senile plaques and vessels, and intraneuronal tau deposition as neurofibrillary tangles. The current study comprises the oxidative modifications associated with the pathological lesions of neuronal damage characterized AD. The repeated exposure to aluminum and heavy metals, mutations in a number of chromosomes and genes, diabetes, cardiovascular diseases, obesity and brain injury, are the major causes for these modifications. There is clearly a need for the identification and development of panels of biomarkers for accurate diagnosis and early detection of sporadic AD. Thus, a collection of the most globally manifested expeditious diagnostic tools for early detection of AD is outlined in this review. Also, a survey of the vast clinically approved therapeutic modalities for restricting and even treating the symptoms of AD is summarized. These arguments provide useful information in both understanding pathogenesis as well as accessing the novel treatment approaches for AD.
