Neurodegenerative diseases including Alzheimer’s, Parkinson’s and Huntington disease are have serious concern
due to its effect on the quality of life of affected persons. Neurodegenerative diseases have some limitations for both diagnostic as well as at treatment level. Introducing nanotechnology, for the treatment of these diseases may contribute significantly in solving the problem. There are several treatment strategies for the neurodegenerative diseases, but their limitations
are the entry into the due to the presence of the blood-brain barrier (BBB). The present review highlights the application of
nanotechnology during last 20 years for the treatment of neurodegenerative diseases.
