Disorders of the Autonomic Nervous System, the fifth volume in The Autonomic Nervous System book series, is a description of the disorders which give rise to autonomic failure and orthostatic hypotension. Each chapter is prepared by an international authority in the diagnosis and treatment of that disorder. The language and terminology are clear enough to promote understanding of the clinical problems and the underlying concepts of basic science. The most recent data, especially that derived from molecular biology, is included in the discussions of relevant diseases. Hence, the volume provides an unparalleled source of information about this area of medicine and will be helpful not just to practising clinicians but also to basic scientists researching in the field who need to familiarize themselves with the clinical problems.
