Abstract: Central nervous system disorders are prevalent, profoundly debilitating, and poorly
managed. Developing innovative treatments for these conditions, including Alzheimer's disease,
could significantly improve patients' quality of life and reduce the future economic burden on
healthcare systems. However, groundbreaking drugs for central nervous system disorders have
been scarce in recent years, highlighting the pressing need for advancements in this field. One significant
challenge in the realm of nanotherapeutics is ensuring the precise delivery of drugs to their
intended targets due to the complex nature of Alzheimer's disease. Although numerous therapeutic
approaches for Alzheimer's have been explored, most drug candidates targeting amyloid-β have
failed in clinical trials. Recent research has revealed that tau pathology can occur independently of
amyloid-β and is closely correlated with the clinical progression of Alzheimer's symptoms. This
discovery suggests that tau could be a promising therapeutic target. One viable approach to managing
central nervous system disorders is the administration of nanoparticles to neurons, intending to
inhibit tau aggregation by directly targeting p-tau. In Alzheimer's disease, beta-amyloid plaques
and neurofibrillary tau tangles hinder neuron transmission and function. The disease also triggers
persistent inflammation, compromises the blood-brain barrier, leads to brain shrinkage, and causes
neuronal loss. While current medications primarily manage symptoms and slow cognitive decline,
there is no cure for Alzheimer's.
