Advances in Diagnosis and Management of Atypical Demyelinating Diseases

The last two decades have seen tremendous progress in understanding central nervous system (CNS) demyelinating diseases, heralding an exciting new era for the diagnosis and treatment of patients with a variety of non-multiple sclerosis neuroinflammatory diseases. This article comprehensively reviews atypical CNS demyelinating diseases, beginning with the general approach to CNS demyelination, continuing with suggestions to facilitate the initial evaluation, and followed by a discussion about specific diseases (neuromyelitis optica, myelin oligodendrocyte glycoprotein antibody disease, acute disseminated encephalomyelitis, iatrogenic CNS demyelination, and transverse myelitis). MRI examples of these disorders are provided to illustrate key radiographic findings. The article concludes with recommendations for treatment.
