Neuromyelitis optica spectrum disorder (NMOSD) is associated with a faster loss of white matter volume in the brain, but taking the corticosteroid prednisolone may help counter this effect, according to a small study in Japan. The brain’s white matter contains the long, wire-like projections, or fibers, that nerves use…

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…

Inflammatory episodes in the spinal cord of people with neuromyelitis optica spectrum disorder (NMOSD) resulted in changes in functional connectivity in the brain, an imaging study shows. Functional connectivity refers to the correlation between brain signals over time that reflects functional connections between two or more brain regions. Reduced…

A man’s first manifestation of neuromyelitis optica spectrum disorder (NMOSD) was aseptic meningitis, an inflammation of the meninges (the membranes that enclose the brain and spinal cord) without evidence of a bacterial infection, which is unusual and made a quick diagnosis difficult, says a report from Japan. The man…
