Inflammatory disorders of the nervous system, although individually uncommon, collectively make up 10-20% of acute paediatric neurology presentations and many are potentially treatable. Research into them is lagging behind adult research, but better diagnosis and often simple treatments could lead to substantial clinical benefit and reduction in long-term disability. This book provides a detailed and comprehensive summary of the childhood diseases that are, or are likely to be, caused by the immune system. The authors not only describe these disorders and their treatments comprehensively, helping pediatricians and pediatric neurologists to improve their understanding and recognition of the conditions, but also highlight recent and exciting developments that will be of considerable importance in the future.
