'This book aims to provide a comprehensive review of sleep and mental illness. This it achieves with aplomb. A thoughtprovoking foreword is followed by chapters divided into three subsections. The basic sciences section is up to date and concise, with useful tables and relevant references. … It will be most useful to psychiatrists and psychologists. However, other sleep specialists, including basic scientists, neurologists and respiratory physicians, will also find it an invaluable resource.' The British Journal of Psychiatry
