"Advances in our understanding of the brain's workings have revitalized our faltering efforts to understand the ubiquitous symptom of fatigue. This book is a succinct yet comprehensive summary of what we have learned so far."
-- Michael Sharpe, Professor of Psychological Medicine and Symptoms Research, University of Edinburgh

Although fatigue has been actively investigated for more than 100 years, we have progressed little in either its theoretical or practical understanding. Fatigue has been considered to be both a symptom and an illness. Fatigue is a primary reason for patient visits to the physician's office, but it is difficult to measure and offers doctors little important information for diagnosis. Fatigue as a Window to the Brain gathers experts on a wide variety of disorders to consider what the presence of fatigue tells us about how the brain works-more specifically, to identify the neural mechanisms potentially responsible for fatigue. The book looks at many of the major conditions in which fatigue is observed, with the hope that patterns may emerge that will suggest paths for future research. It will be of interest to neuroscientists, clinical researchers, and physicians and other clinicians.
