To date more than eighty thousand patients worldwide have received deep brain stimulation (DBS), mainly in order to alleviate symptoms of treatment-resistant disorders such as tremor associated with Parkinson’s disease, essential tremor, chronic pain, epilepsy, obsessive compulsive disorder, major depression and Tourette syndrome. The number of indications for neurological and psychiatric conditions using this technology is rapidly increasing, raising important societal and ethical issues that cannot be dealt with by scientists and clinicians on their own, but need discussions among all possible stakeholders on questions such as: what are the comprehensive risks and benefits of this technology? what is the real impact on patients’ life, in terms of health, quality of life and personal identity? This Research Topic provides an overview of potentials and limitations of deep brain stimulation as used to treat neurological and psychiatric conditions, bringing together Mini Reviews, Perspectives and Opinion papers from key stakeholders interested in the development and social impact of this technology. It is also a continuation of the debate that started among scientists, clinicians, patients, sociologists, journalists, philosophers and other experts during the “brains in dialogue on deep brain stimulation” workshop that was organized in September 2010 in Warsaw, Poland, by the FP7 project bid – brains in dialogue (www.neuromedia.eu) coordinated by the Interdisciplinary Laboratory of SISSA (Trieste, Italy).

The consideration of ethical and social issues related to current uses of deep brain stimulation (DBS) as well as investigational uses should now be an integral part of contemporary DBS practice. Scholarship, interdisciplinary work groups, and peer processes have helped articulate standards that need to be respected and implemented in current DBS practice. Integrating new knowledge and interdisciplinary ethical perspectives could be considered a sign of the maturity and rigor of a DBS program. Still, investigational uses of DBS carry tremendous hope but also touch on sensitive and thorny ethical questions. These questions can benefit from the ethical wisdom generated for standard uses of DBS but also challenge current practices and professional conduct. Realizing this, interdisciplinary expert groups have been convened to identify and flesh out ethical guideposts for cutting-edge research in DBS. By implementing these ethical frameworks, DBS is an opportunity to develop promising treatments for a set of vulnerable and sometimes underserved patients while keeping their best interests in sight.

This issue of International Review of Neurobiology brings together cutting-edge research on neuromodulation. It reviews current knowledge and understanding, provides a starting point for researchers and practitioners entering the field, and builds a platform for further research and discovery. - Brings together cutting-edge research on neuromodulation - Reviews current knowledge and understanding - Provides a starting point for researchers and practitioners entering the field, and builds a platform for further research and discovery

Neuromodulation is among the fastest-growing areas of medicine, involving many diverse specialties and affecting hundreds of thousands of patients with numerous disorders worldwide. It can briefly be described as the science of how electrical, chemical, and mechanical interventions can modulate the nervous system function. A prominent example of neuromodulation is deep brain stimulation (DBS), an intervention that reflects a fundamental shift in the understanding of neurological and psychiatric diseases: namely as resulting from a dysfunctional activity pattern in a defined neuronal network that can be normalized by targeted stimulation. The application of DBS has grown remarkably and more than 130,000 patients worldwide have obtained a DBS intervention in the past 30 years—most of them for treating movement disorders. This Frontiers Research Topics provides an overview on the current discussion beyond basic research in DBS and other brain stimulation technologies. Researchers from various disciplines, who are working on broader clinical, ethical and social issues related to DBS and related neuromodulation technologies, have contributed to this research topic.

This book is written for graduate students, researchers, and practitioners who are interested in learning how the knowledge from research can be implemented in clinical competences. The first section is dedicated to deep brain stimulation, a surgical procedure which is the paramount example of how clinical practice can take advantage from fundamental research. The second section gathers four chapters on four different topics and illustrates how significant is the challenge to translate scientific advances into clinical practice because the route from evidence to action is not always obvious. It is hoped that this book will stimulate the interest in the process of translating research into practice for a broader range of neurosurgical topics than the one covered by this book, which could result in a forthcoming more comprehensive publication.

This series, sponsored by the European Association of Neurosurgical Societies, has already become a classic. In general, one volume is published per year. The advances section presents fields of neurosurgery and related areas in which important recent progress has been made. The technical standards section features detailed descriptions of standard procedures to assist young neurosurgeons in their post-graduate training. The contributions are written by experienced clinicians and are reviewed by all members of the editorial board.

Abnormal and clinical psychology courses are offered in psychology programs at universities worldwide, but the most recent major encyclopedia on the topic was published many years ago. Although general psychology handbooks and encyclopedias include essays on abnormal and clinical psychology, such works do not provide students with an accessible reference for understanding the full scope of the field. The SAGE Encyclopedia of Abnormal and Clinical Psychology, a 7-volume, A-Z work (print and electronic formats), will be such an authoritative work. Its more than 1,400 entries will provide information on fundamental approaches and theories, various mental health disorders, assessment tools and psychotherapeutic interventions, and the social, legal, and cultural frameworks that have contributed to debates in abnormal and clinical psychology. Key features include: 1,400 signed articles contained in 7 volumes and available in choice of print and/or electronic formats although organized A-to-Z, front matter includes a Reader’s Guide grouping related entries thematically back matter includes a Chronology, Resource Guide, Bibliography, and detailed Index entries conclude with References/Further Readings and Cross References to related entries the Index, Reader’s Guide themes, and Cross References between and among entries all combine to provide robust search-and-browse features in the electronic version.

Written by noted authorities in geriatric psychiatry, this volume is a clinically oriented guide to the diagnostic workup and treatment of psychiatric and neuropsychiatric disorders in elderly patients. The book describes in detail the neurologic and neuropsychiatric patient assessment and the use of all treatment modalities, both psychotherapeutic and pharmacologic, in elderly patients. Chapters discuss the treatment of disorders in all clinical settings—inpatient, outpatient, emergency, primary care, assisted living, and long-term care. Algorithms for workup and treatment are included, as well as case studies and personal accounts by patients and care providers. Appendices provide drug information and additional resources.

This book sheds new light on neurodegenerative disorders as systemic diseases. Classically, neuronal cell death was a hallmark of such disorders. However, it has become evident that neural dysfunction is more important in the pathophysiology of neurodegenerative disorders. More recently, the prionoid-spreading hypothesis of disease-causing molecules has attracted a great deal of attention. Therapeutic strategies thus must be reconsidered in the light that neurodegenerative disorders are indeed systemic diseases. The first part of this book introduces the concept of neurodegeneration in biology and pathophysiology. The second part focuses on clinical evaluation and biomarkers from the perspective of this new concept, while the third summarizes the risk factors of neurodegeneration. The fourth part of this work indicates future directions of treatment, and the final part discusses health promotion for prevention and quality of life. This book will be of interest to both researchers and medical personnel, and provides a fresh approach to neurodegenerative diseases, paving the way to new research and improved quality of health care for patients.
