Demyelinating Disorders of the Central Nervous System in Childhood

Description

Although multiple sclerosis and other disorders of myelin formation and repair are most commonly associated with adults, they can also occur in infants, children and adolescents. Up to 5 percent of those with MS experience symptoms before the age of 18, and the number of cases diagnosed is rising. There is a lack of awareness about these diseases in childhood, however, even amongst pediatric neurologists and MS specialists. Demyelinating Disorders of the Central Nervous System in Childhood provides comprehensive coverage of these diseases, highlighting throughout the differences between management in childhood and in adults. With sections dedicated to the diagnosis, course, treatment and biology of pediatric MS, detailed chapters on other childhood demyelinating diseases, including acute disseminated encephomyelitis, optic neuritis, acute complete transverse myelitis and neuromyelitis optica, are also provided. Essential reading for pediatric neurologists and MS specialists, this book will also be valuable reading for adult neurologists and pediatricians.
