Advance Nanotechnology-Based Drug Delivery Systems for Alzheimer's Disease: Advancements and Future Perspectives

Alzheimer's Disease (AD) is a progressive neurodegenerative disorder characterized by cognitive decline and memory loss, significantly impacting the quality of life for affected individuals. This manuscript explores various innovative therapeutic strategies aimed at enhancing drug delivery to the brain, particularly through the use of nanotechnology. This paper discussed the application of Solid Lipid Nanoparticles (SLNs), dendrimers, and Polymeric Nanoparticles (PNPs) in targeting the Central Nervous System (CNS) to improve bioavailability and therapeutic efficacy. The findings indicate that these advanced delivery systems can enhance brain penetration, reduce Amyloid-Beta (Aβ) deposition, and improve cognitive functions in animal models of AD. Furthermore, the review highlights the challenges associated with these technologies, including limited scalability and potential toxicity, while suggesting future directions for research and development in the field of AD treatment.
