With the population getting older and with a corresponding increase in neurodegenerative diseases (NDs) worldwide, developing drug delivery systems that can overcome conventional barriers in treating these diseases is the need of the hour. Drug delivery by nanotechnology has great promise for detecting and treating a wide range of neurodegenerative conditions. This new book provides an informative overview of the cutting-edge applications of various nanocarriers that encapsulate active compounds to effectively treat NDs.
