Introduction Neurology is commonly portrayed as a difficult topic in the MRCP examinations. This book has been written to try and help you through both the written and clinical sections of the exam and hopefully prove that Neurology is not as difficult as it may at first seem. The book is not designed, however, to be a definitive Neurology textbook but rather a revision guide for the MRCP exams. The first section of the book describes the neurological disorders you need to know about for the MRCP and will be useful throughout the different parts of the exam. The second section of the book concentrates on the PACES section of the exam. The third section provides questions to test your knowledge before the Part 1 and Part 2 exams. Each section is set out in roughly anatomical fashion, starting with disorders of the cortex and moving down through the nervous system to finish at the muscle. This systematic way of thinking is useful for both the written and clinical exam and will be used as the basis for the book. It is important to recognise that in practice, different neurologists may all perform the neurological examination slightly differently and in their own idiosyncratic way. For PACES it is advisable to perform a standard textbook neurological examination as set out in Section 2 of this book. Dr Jonathan Rohrer MRCP (UK) Dr Jonathan Kennedy MRCP (UK) xi
