Comprehensive review on Alzheimer's Disease: Pathophysiology and its Treatment

Neurodegenerative disorders are marked by the loss of brain neuron activity, resulting in gradual cognitive impairment. The effects of neurodegenerative diseases are severe in terms of pathology and the cost of patient care. The aged, in general, are the most vulnerable. Alzheimer's disease (AD) is a brain ailment that causes cell degradation and is the leading cause of dementia, identified by a loss of thinking ability and independence in daily tasks. The amyloid cascade hypothesis, which attributes clinical signs/symptoms to an abundance of amyloid-beta (Aβ) peptides, enhanced deposition into amyloid plaques, and eventually neuronal destruction, is one theory for pathogenesis AD. The use of acetylcholinesterase inhibitors in AD treatment is based on their favorable effects on the disease's functional, cognitive and behavioral symptoms. However, their involvement in AD pathogenesis is uncertain. This comprehensive review will provide an overview of AD, including the pathophysiology, causes, treatments, and future treatment.
