Abstract

AbstractRecent times have witnessed an upsurge in the incidence of neurodegenerative disorders such as Alzheimer's disease, Parkinson's disease, Huntington's disease, Prion disease, and amyotrophic lateral sclerosis. The treatment of the same remains a daunting challenge due to the limited access of therapeutic moieties across the blood–brain barrier. Engineered nanoparticles with a size less than 100 nm provide multifunctional abilities for solving these biomedical and pharmacological issues due to their unique physico‐chemical properties along with capability to cross the blood–brain barrier. Needless to mention, there is a scarcity of review articles summarizing recent developments of various nanomaterials including liposomes, polymeric nanoparticles, metal nanoparticles, and bio‐nanoparticles toward the therapeutic and theranostics applications for various neurodegenerative disorders. Here, a broad spectrum of nanomedicinal approaches to eradicate neurodegenerative disorders is provided, along with a brief account of neuroprotection and neuronal tissue regeneration, current clinical status, issues related to safety, toxicity, challenges, and future outlook.
