This interdisciplinary volume presents both recent research and solid clinical information on the neuropsychiatric aspects of multiple sclerosis. The information in Multiple Sclerosis: A Neuropsychiatric Disorder is presented in a format that is valuable to everyone from scientists and clinician-specialists to primary care physicians. Depression, euphoria, indifference, and other mood and cognitive symptoms are among the most noticeable characteristics of multiple sclerosis. In Multiple Sclerosis: A Neuropsychiatric Disorder the authors not only address how to deal with these symptoms, they also examine the ethical questions of treating symptoms such as euphoria and indifference (i.e., should they be treated at all, as they might play a positive role in patients" interaction with their environment).
