Magnetic resonance imaging (MRI)

A longer time from the first symptoms of neuromyelitis optica spectrum disorder (NMOSD) to seeing a neuroimmunology specialist and having an MRI scan is associated with a misdiagnosis, a new study shows. The risk of misdiagnosis was also higher among those who first presented with persistent nausea, vomiting, or…

People with neuromyelitis optica spectrum disorder (NMOSD) and related neurological conditions show reduced brain volume compared with individuals without such diseases, a new study highlights. The results indicate that rates of volume loss in the thalamus — a brain region that helps to relay motor and sensory signals —…

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…

Asymptomatic, or “silent,” MRI lesions are not common during disease remission in patients with aquaporin-4 antibody neuromyelitis optica spectrum disorder (AQP4-NMOSD) and myelin oligodendrocyte glycoprotein antibody disease (MOGAD), but are associated with imminent relapse when they do occur, according to a recent U.K. study. “Results of…
