Nanomedicine for Alzheimer's Disease: Diagnostic and Therapeutic Progress.

The complex nature of the pathophysiology and limited treatment options of AD make it a huge challenge in healthcare. The recent developments in nanotechnology have given fresh hope for diagnosing and treating AD, which could serve as a way out of the existing problems. This review dwells on the role of nanotechnology in AD and its applications at its early stages through the development of nanosensors and boost imaging methods. Additionally, nanotechnology-driven therapeutic strategies are being investigated with nanoparticle-based drug delivery systems that aim to target the blood-brain barrier, among others. Current research innovations, clinical trials, and prospects highlight the transformative potential of nanotechnology in reshaping AD management. Ethical issues related to applying nanomedicine in neurodegenerative diseases, as well as fears about nanoparticles, are carefully analyzed herein. Finally, this review concludes with a synthesis of how nanotechnology has affected Alzheimer's Disease (AD) while emphasizing emerging trends and future directions toward advancing research on Alzheimer's Disease (AD). This comprehensive overview underscores the pivotal role of nanotechnology in revolutionizing AD prognosis and therapy, paving the way for personalized and effective treatment strategies.
