Book excerpt: Technological advances have been responsible for many developments in the field of healthcare in recent years. One of the areas opened up by new technological possibilities is that of cybertherapy and telemedicine, which involves the use of computer and communications technology to provide improved health services that are sometimes qualitatively different from those provided in traditional in-person therapeutic experiences. This book, the Annual Review of Cybertherapy and Telemedicine (ARCTT), covers a wide variety of topics of interest to the mental health, neuroscience and rehabilitation communities, presented in a carefully structured sequence. The book is divided into seven main parts. Following an editorial, the section entitled White Paper discusses critical issues for the future of the field. This is followed by sections containing critical reviews, evaluation studies, original research and clinical observations. Work in Progress, the last section, includes papers describing future research work. The book will be of interest to both health professionals and patients, and to anyone else interested in the continued improvement of healthcare systems.
