Alzheimer's disease is an eventually destroying disease of the overaged people featured by the dynamic and gradual brain erosion because of construction of extracellular plaques in the hippocampus. It is an undertreated and underrecognized disease that is becoming a major public health concern. From the study, it is known that production of plaques takes place twenty years back, before the commencement of clinical syndromes. As per report, in 2019, above 50 million people got into Alzheimer's disease. Recent developments include improved clinical diagnostic guidelines and improved treatment of both cognitive disturbance and behavioral problems. Treatment majorly focus on cholinergic therapy has been clinically evaluated by different studies including randomized, double-blind, placebo-controlled, parallel-group studies measuring performance-based tests of cognitive function, activities of daily living, and behavior. The presence of extracellular plaques of insoluble β-amyloid peptide (Aβ) and neurofibrillary tangles (NFT) containing hyperphosphorylated tau protein (P-tau) in the neuronal cytoplasm is a remarkable pathophysiological cause in patients' brains. The graph of increasing patients, suffering from Alzheimer's disease, is being ascended. The outcome of this turn into fatal, deadly situation. So, there is a possibility of breaking down world economics and human strength. There is a different kind of organic as well as inorganic nanocomponent group, those have been pursued with satisfaction. By studying and researching over pathogenesis specifically, diagnosis of this AD as per its symptoms is possibly done. Treatment of this neurodisease is under processing. The experts are playing an extremely appreciable role for displacing this disease completely. The present review summarizes the pathophysiology and role of the nanoparticle in the diagnosis and treatment of AD. [ABSTRACT FROM AUTHOR]
