The activity of an immune-regulating protein is significantly lower just before or during a relapse in people with neuromyelitis optica spectrum disorder (NMOSD), a recent study has found. This discovery could lead to new ways to monitor disease activity and develop treatments. The protein, called the aryl hydrocarbon receptor…

A predictive model based on laboratory and clinical risk factors for relapses in neuromyelitis optica spectrum disorder (NMOSD) was found to accurately discriminate NMOSD patients experiencing a relapse within one year of diagnosis from those without a relapse, a study showed. The identified risk factors were numbers and ratios…

The circulating levels in the blood of six inflammatory proteins may help predict the risk of relapse and severe attacks in people with neuromyelitis optica spectrum disorder (NMOSD), a study from China reports. Four of these inflammation-related proteins — FGF-23, DNER, GDNF, and SLAMF1 — were used to build…

About 1 in 10 people who are hospitalized for neuromyelitis optica spectrum disorder (NMOSD) are readmitted to the hospital within 30 days, or about one month after discharge, a U.S. study found. Older patients — specifically those in the age range of 65 to 74 — and individuals who…

Older age, a poor response to steroids, and the need for a blood-cleaning procedure known as plasma exchange all were found to increase the likelihood of a diagnosis of neuromyelitis optica spectrum disorder (NMOSD) among people experiencing a first optic neuritis attack, a small study shows. These findings led…

Out of four markers of nervous system cell injury, blood levels of neurofilament light chain (NfL) were found to best predict disability worsening in people with neuromyelitis optica spectrum disorder (NMOSD), a study showed. Measures of blood NfL levels at the time of an NMOSD attack were the only ones…

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…

Age, sex, and spinal lesions may be risk factors for developing pain due to nerve damage — called neuropathic pain — in people with neuromyelitis optica spectrum disorder (NMOSD), according to a new study. Specifically, an older age at disease onset, female sex, and a greater number of lesions…
