Rapid advances in the field of CNS disorders opened a new route of diagnostic and therapy.Knowledge of current concepts associated with diseases and disorders of CNS around the world is a crucial issue for providing appropriate evaluation, referral and treatment of patients with diseases of CNS.The main goal of this book is to provide broad based current knowledge on diverse fields of diseases and disorders of CNS on a high level.The book contains a compact text from several neurosurgical sources consisting of journals and books, which have been published currently in the neurosurgical field.The topics have been arranged in “Top Down” starting from cerebral diseases to spine to provide a systematically view and knowledge about history, anatomy, imaging, clinical assessment and operative and non-operative therapy of diseases and disorders of CNS.The text has been made spare and concise therefore it could be read quickly in the clinic during patient rounds, daily work and also in the operating room.We have created about 120 tables by ourselves in hope to keep attention to the essential points and to avoid unnecessary details.In addition, we have integrated about 193 suitable original photographs into the book.The most important clinical and radiological features were usually labeled and highlighted in color.The readership will be wide ranging including from medical student, residents and of course neurosurgeons and neuro-radiologists.The book may also be of interest to physicians and nurses working at the ICU as well as patients with diseases of CNS.We are especially grateful to Dr. A. Khadem and Dr. A. Ghasemi for bringing this book to editorial and technical completion.
