Myelin is a protective layer that enwraps the axonal terminals and is an essential component of the central nervous system white matter. Loss of myelin leads to conduction block in the axon leading to demyelinating disorders. Inherited poor formation of myelin is known as hypomyelination, and abnormally formed myelin is called dysmyelination. Demyelinating disorders exclude diseases where degeneration of the axon is the initial event and myelin is degraded secondarily. Most neurologists use the term demyelination only for acquired forms of loss of myelin with relative preservations of axons due to inflammation such as multiple sclerosis. Demyelinating disease in children may be monophasic (e.g., acute disseminated encephalomyelitis, optic neuritis, and transverse myelitis) or chronic (multiple sclerosis and neuromyelitis optica). Pediatric multiple sclerosis is the most common demyelinating disorder in children. Recent genetic and clinical researches have significantly improved our understanding of the diverse spectrum of pediatric demyelinating disorders. In this chapter, an updated summary of the current knowledge on the categories, diagnosis, as well as management of pediatric demyelinating disorders has been presented.
