Researchers have identified a rare case of co-existing neuromyelitis optica spectrum disorder (NMOSD) and subacute combined degeneration (SCD) — two distinct disorders marked by nerve damage in the brain or spinal cord. The case highlights the possibility that NMOSD may be the underlying driver of the vitamin B12 deficiency…

Women are more likely to have neuromyelitis optica spectrum disorder (NMOSD) symptoms, or a rebound of symptoms, within three months after delivering a baby, a Chinese study found. Women who didn’t receive immunotherapy during pregnancy and the postpartum period were more than five times as likely to have…

A 67-year-old man developed a rare case of neuromyelitis optica spectrum disorder (NMOSD) after his third dose of the COVID-19 vaccine, a study reports. A review of published literature showed this case adds to 15 other reported cases of post-COVID-19 vaccination NMOSD onset, which appear to show similar clinical…

Adults with neuromyelitis optica spectrum disease (NMOSD) who are positive for antibodies against the aquaporin-4 (AQP4) protein have a higher prevalence of oval-shaped masses surrounding the optic nerve in their eyes than healthy people, a study showed. Although these masses were significantly linked to older age, their occurrence was…

A young woman had a rebound of neuromyelitis optica spectrum disorder (NMOSD) toward the end of her pregnancy, for which she underwent plasma exchange and took steroids, according to a report from researchers in the U.S. Because treatment with plasma exchange and steroids did not work well enough, the…

Certain variations in the ESR1 gene — a protein-coding gene for estrogen receptor-alpha — are significantly more common among women with neuromyelitis optica spectrum disorder (NMOSD) or multiple sclerosis (MS) than among healthy women, a small study suggests. Such differences were not observed between men with these…

Ultomiris (ravulizumab) — Alexion Pharmaceuticals’ approved therapy for certain complement-associated disorders — prevents relapses in adults with neuromyelitis optica spectrum disorder (NMOSD) who are positive for antibodies against the aquaporin-4 (AQP4) protein. The therapy also helped preserve walking skills, with treated patients showing a markedly lower risk of experiencing clinically…

Treatment with Uplizna (inebilizumab-cdon) can reduce levels of antibodies that drive neuromyelitis optica spectrum disorder (NMOSD), new clinical trial data show. The data also show that, among patients who aren’t on Uplizna, NMOSD attacks are often preceded by a sharp rise in levels of disease-driving antibodies and/or antibody-producing…

Brain age gap (BAG) — the difference between calendar age and predicted brain age as determined by MRI scans — was significant in adults with neuromyelitis optica spectrum disorder (NMOSD), and may predict disability in patients, a study found. The BAG was even greater in people with the related…

Neutrophils, a set of immune cells, from people with aquaporin-4 (AQP4) antibody-positive neuromyelitis optica spectrum disorder (NMOSD) are resistant to certain forms of cell death, a study found. NMOSD patients also had increased blood levels of molecules that might help neutrophils resist cell death pathways. Similar findings weren’t observed…
