AN COMPREHENSIVE REVIEW ON ALZHEIMER: A NEURODEGENERATIVE DISORDER

AD is a neurodegenerative disorder that affects a large number of individuals worldwide. It is the most common cause of dementia and the most frequent cause of cognitive impairment. AD is characterized by the presence of tau proteins in the brain, which are essential for the development and progression of the disease. This review focuses on the pathogenesis of AD and its pathophysiology, including the role of Tau proteins in AD. The importance of biosensors in the diagnosis and treatment of AD is highlighted. In this review, we will focus on the various biomarkers associated with AD diagnosis, as well as their application in the clinical diagnosis of AD. Biosensors utilising nanotechnology are being created to enable the precise and sensitive detection of Neurodegenerative Biomarkers, including Tau proteins, which could facilitate early identification and predicting disease progression.
