This Springer Major Reference Work provides a detailed translational overview of neuroimmune diseases for neuroscientists and clinicians, clarifying the pathological mechanisms underlying neuroimmune diseases and building a comprehensive bridge between the latest research findings and their clinical implications in daily practice. The material is presented in two steps. The first section comprises a review of the pathogenic actions of immune cells in brain diseases. Here the authors discuss the mechanisms through which immune cells disrupt the functions of nerve cells. The second section explores the ways in which the brain becomes dysfunctional due to impaired nerve cell function. Based on pathogenesis, diagnostic and therapeutic strategies are discussed for each clinical category. The new edition features updated chapters throughout, including coverage of new findings, new diagnostic criteria, and therapeutic algorithms. Neuroimmune Diseases, 2nd edition, also includes 11 new chapters, including two chapters on COVID-19 and neuroinflammation. The book will be invaluable for use in clinical practice of neuroimmune diseases.
