Neuroimmunology: towards more-accurate diagnosis in neuromyelitis optica.
Fujihara K., Palace J.
Neuromyelitis optica spectrum disorders (NMOSD) can mimic multiple sclerosis (MS). Avoiding misdiagnosis is crucial, because some disease-modifying drugs for MS can aggravate NMOSD, causing blindness and paraplegia. A recent study reports that misdiagnosis of NMOSD as MS occasionally occurs, and that a two-step antibody assay could improve differential diagnosis.
