Nanoparticles – a novel theranostic approach to treat alzheimer’s disease

Abstract

The incidence of Alzheimer’s disease (AD) is increasing day by day worldwide, which results in a poor quality of life. Early diagnosis and treatment of AD is necessary to suppress the progression of the disease. Conventional treatments have several limitations due to the protective blood-brain barrier. In this review, we described a nanoparticle-based approach to crossing the blood-brain barrier for AD detection and treatment. Nanoparticles encapsulate the anti-AD drug and are directed to the target tissues where controlled release of the drug takes place. There are various types of nanoparticles that are used to encapsulate drugs, including solid-based nanoparticles, liposomes, nanoemulsions, iron NPs, cerium NPs, selenium NPs, and gold NPs. In this review, we have described the use of different nanoparticles as nanomedicine. Nanoparticles are also coated with proteins and antibodies for efficient release of drugs. This review aims to provide clinical insights and the importance of nanotechnology in theranostics and describes how nanomedicine has revolutionized the drug delivery approach for AD treatment
