Nanomaterials toward the treatment of Alzheimer’s disease: Recent advances and future trends

We reviewed the four main pathological mechanisms of Alzheimer’s disease, discussed the therapeutic strategies based on nanomaterials from the perspective of pathological mechanisms and put forward a summary and prospect. [Display omitted] Alzheimer’s disease (AD) is a progressive and fatal neurodegenerative condition and the most prevalent cause of dementia. This disease is characterized by progressive cognitive impairment. The prevalence of AD is currently affecting more than 35 million people and is rising worldwide. No efficient therapy is currently available due to low drug potency and a number of various obstacles to delivery. Recent nanotechnological advancements have the potential to offer promising therapeutic options. Progress on nanomaterials as well as their applications in biomedicine is receiving increasing attention, especially the advantages of nanomaterial-based drug delivery systems. The aim of this review is to comprehensively summarize the latest developments in nanomaterial-based strategies for AD treatment, including nanoparticles, liposomes and other options for the delivery of therapeutic compounds and scaffolds for cell delivery strategies. Future research directions are also proposed. We hope this review can provide important information to guide the future development of nanomaterials in AD treatment.
