The Role Of Oxidative Stress In Alzheimer's Disease

Satisfactory Essays
Alzheimer’s disease (AD) is a debilitating illness of the nervous system, affecting millions of geriatric population worldwide. Numerous factors are involved in the disease etiology viz. tau phosphorylation, amyloid β protein (Aβ) accumulation, lipid dysregulation, oxidative stress and inflammation. Among all factors oxidative stress plays a central role in the pathogenesis of AD leading to neuronal dysfunction and cell death (1). Oxidative stress is caused due to the increased production of reactive oxygen species (ROS) which denatures biomolecules such as proteins, lipids and nucleic acids through pathological redox reactions(2). Increased oxidative stress also results in excessive lipid peroxidation, weakening the cell membranes, causing
