"This book discusses basics of brain diseases and role of nanobiotechnology in existing treatment options for neurodegenerative disorders. It begins with an overview of brain diseases and need for novel drug delivery approaches. It highlights the current route for the intranasal advanced drug delivery systems for brain diseases. It also discusses the innovative categories of drug delivery systems, including mesoporous silica nanoparticles, polymeric nanocarriers, lipid-based nanocarriers through multi-responsive DDSs and their implications in brain disorders. Includes overview of brain diseases and highlights the need for novel drug delivery approaches. Focusses on theoretical aspects of the advanced drug delivery systems for brain diseases including challenges and progress in nose-to-brain delivery. Provides an overview of the technological approaches and their implications in the neurodegenerative disorders, CNS, and brain drug delivery in brain cancer. Discusses key advances in the development of polymer nanoparticles for drug delivery to the CNS. Review role of herbal medicines and naturally derived polymeric nanoparticle for the treatment of neurodegenerative disorders. This book is aimed at graduate students and researchers in biomedical engineering, biotechnology, drug delivery, and neurology"--
