This makes it difficult to deliver beneficial drugs across the BBB to treat Central Nervous System (CNS) diseases. Great progress has been made in research efforts in improving the BBB permeability in recent years, thus providing a lot of help to delivery drug to the targeted brain part and to treat CNS diseases. This paper discusses the anatomical and functional structures of the BBB and summarizes the methods and mechanisms of increasing BBB permeability comprehensively. It also elaborates on the physics, chemistry, biology and nanocarrier aspects to improve drug delivery to the brain, and introduces some specific drug delivery. Keywords Blood brain barrier, Drug delivery system to brain, Central nervous system, Diseases 血脑屏障(BBB)是机体最重要的屏障之一。它是由毛细血管内皮细胞形成的血液与脑组织间的屏障。 BBB 不仅可以阻止有害的物质进入脑内，还可以选择性地将有害物质或过剩物质泵出脑外，为脑组织提 供了一个相对
