This Neurology textbook is intended for international medical students and bilingual education in Chinese medical students. We hope it will also be useful for neurologists, non-neurologist cliniaans, nurses, and other healthcare workers. As a textbook mainly for medical students, we tried to keep the content direct and clear. Only widely accepted notions and facts are included, rather than unsupported opinions or recent progress in research. Compared with other Neurology textbooks in English language, this textbook puts more emphasis on anatomy of nervous system, principles of topical diagnosis and neurological examination.
