Abstract
Objective: Neuromyelitis optica spectrum disorders (NMOSD) is often misdiagnosed or delayed because of the complex and diverse clinical manifestations, especially the atypical initial presentation. Hyponatremia can be an infrequently isolated initial presentation of NMOSD and is associated with hypothalamus involvement. Awareness of this mechanism will help clinicians to identify NMOSD early, treat it in time and improve the prognosis.
Methods: We describe a 36-year-old woman who developed repeated hyponatremia and then experienced diplopia. Serum AQP4, MOG, MBP and GFAP antibody were detected, and NMOSD was finally diagnosed.
Results: She responded well to high-dose glucocorticoids. Sequential treatment with mycophenolate mofetil (MMF) was prescribed. Two-month follow-up revealed full recovery. So far, after 10 months, the patient still has no recurrence.
Conclusion: For young patients, repeated hyponatremia, with or without slight fever, and no evidence of obvious infection, brain magnetic resonance imaging (MRI) and serum AQP4/MOG antibody detection may be useful to determine whether there is a possibility of NMOSD.

The International Journal of Neuroscience publishes original research articles, reviews, brief scientific reports, case studies, letters to the editor and book reviews concerned with problems of the nervous system and related clinical studies, epidemiology, neuropathology, medical and surgical treatment options and outcomes, neuropsychology and other topics related to the research and care of persons with neurologic disorders. The focus of the journal is clinical and transitional research. Topics covered include but are not limited to: ALS, ataxia, autism, brain tumors, child neurology, demyelinating diseases, epilepsy, genetics, headache, lysosomal storage disease, mitochondrial dysfunction, movement disorders, multiple sclerosis, myopathy, neurodegenerative diseases, neuromuscular disorders, neuropharmacology, neuropsychiatry, neuropsychology, pain, sleep disorders, stroke, and other areas related to the neurosciences.
