Introduction: Nanomedicine In The Brain

In recent years, as the incidence of brain diseases in the population has gradually increased, the treatment of neuropsychiatric diseases cannot be ignored. There are many pathogenesis of neuropsychiatric diseases, such as neuronal damage, intercellular signaling disorder, and inflammatory reactions. On the other hand, blood-brain barrier (BBB) as the protective layer of the brain, to some extent, hinders the release and delivery of conventional drugs. Nanomedicines, with many excellent physiochemical properties, such as multiple modifications and surface functionalization, have attracted widespread attentions in the scientific community. In this chapter, we provide a broad overview of brain diseases and summarize the applications of nanomedicine in neuropsychiatric disorders, as well as challenges and prospects for future research. We hope that this chapter will enable readers to have a new understanding of brain diseases and nanomedicine and to promote the developments of nanomedicine in brain diseases in clinic.
