Autoimmune encephalitis, diseases where the immune system attacks the brain, have become a fast-moving field of study in recent years. The authors, Drs Josep Dalmau and Francesc Graus, have played pivotal roles in the discovery of these diseases. Here, they provide a comprehensive clinical guide to the differential diagnosis of these disorders, illustrated with over 200 figures, 30 videos and numerous clinical vignettes, many from their own practice. Clinical descriptions are straightforward, emphasizing distinctive diagnostic clues for each disease. The strengths and weaknesses of diagnostic tests and clinical criteria are discussed extensively, as well as the best evidence supporting the use of available treatments. There is an up-to-date description of immunological triggers and comorbidities, and well-illustrated and clearly summarized pathogenic mechanisms and disease models.
