It has been 24 years since the first edition of Neurology and Neurosurgery Illustrated was published. On writing each new edition, we are always surprised at the number of changes required. For this edition there is an additional change. Ian Bone has retired from clinical practice and Geraint Fuller has joined to edit and update this edition. As in all previous editions there have been updates in many areas.
With the increasing trend to sub-specialise within clinical neuroscience, we have become increasingly dependent on colleagues for advice. The following have provided many valuable suggestions – Laurence Dunn, Patricia Littlechild and Jerome St George (neurosurgery), Colin Smith (neuropathology), Alison Wagstaff (neuroanaesthetics), Donald Hadley (neuroradiology) and Roy Rampling (oncology). We would like to offer sincere thanks to all. Finally we are indebted to Ailsa Laing of Elsevier for her patience and gentle encouragement.
