When the immune system launches an attack to fight off a cytomegalovirus infection, immune cells may accidentally target aquaporin-4 (AQP4), a protein found at the surface of neuron-supporting cells. That’s the hypothesis suggested by researchers who analyzed the immune cell receptors of people with and without neuromyelitis optica spectrum…

The presence of lesions in the brain’s middle medulla, a control center for breathing, increases the likelihood of acute respiratory failure in people with neuromyelitis optica spectrum disorder (NMOSD), a study suggests. While middle medullary lesions on MRI were the key predictor of acute respiratory failure in patients with…

The rate of disease onset or relapse of neuromyelitis optica spectrum disorder (NMOSD) after a SARS-CoV-2 infection — the virus that causes COVID-19 — is extremely low, at about 1 in 50 million, according to a worldwide review study. The occurrence of NMOSD was even lower, at 1 in…

Eating more oily fish and raw vegetables may decrease a person’s risk of developing neuromyelitis optica spectrum disorder (NMOSD), according to a new study of the autoimmune disease that used genetic data. While most foods reviewed in the study — including beef, bread, cheese, wine, poultry, and also coffee…

CCL2, a signaling protein that recruits immune cells to sites of injury, may play a key role in driving the nerve damage that results from antibodies against the aquaporin-4 (AQP4) protein in neuromyelitis optica spectrum disorder (NMOSD), a study suggests. The signaling protein was found to be elevated in…

The risk of neuromyelitis optica spectrum disorder (NMOSD) attacks following vaccination is low, and such attacks have not been found to be associated with any particular type of vaccine, according to a review study. Also, post-vaccine attacks tended to happen more frequently in men, patients negative for antibodies against…

Familial clustering of neuromyelitis optica spectrum disorders (NMOSD) — having more cases within families than what would be expected — is more common than originally thought. That’s according to a new study whose findings highlight a complex genetic predisposition to the progressive autoimmune disease. Certain DNA variants were shared…

Living with neuromyelitis optica spectrum disorder (NMOSD) and resulting disability can make it hard to find and keep employment, according to a small U.S. study that nonetheless involved patients from more than a dozen states. Group discussions with 20 people with the rare autoimmune disease — of varying races…

People who are younger at the onset of neuromyelitis optica spectrum disorder (NMOSD) and those with multiple organ involvement at the first attack by the disease have a higher risk of relapse during treatment with traditional immunosuppressants, a study showed. A reduction in the levels of antibodies against…

The annual prevalence of neuromyelitis optica spectrum disorder (NMOSD) in the U.S. is considerably higher than previously estimated, affecting about nine out of every 100,000 people, according to a study that analyzed 2021 electronic health records. The data also showed that the disease is more than twice as common…
