Neuromyelitis optic spectrum disorder after a presumed COVID-19 infection


  • Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may be linked to the development of neuromyelitis optica spectrum disorder (NMOSD) in humans.

Why this matters

    NMOSD is an autoimmune disease of the central nervous system and often involves the spinal cord and optic nerves. The exact pathogenic mechanism for NMOSD remains unknown. However, evidence suggests that viral infections, such as SARS-CoV-2, may play a role in the development of NMOSD. The results from this case study may help increase the understanding of NMOSD triggered by viral infections.
