Stressful life events and a history of depression may be associated with an increased risk of developing neuromyelitis optica spectrum disorder (NMOSD).
Why this matters
NMOSD is an autoimmune disease which affects the optic nerves and spinal cord and results in severe optic neuritis and transverse myelitis. Onset of NMOSD can be brought forth by genetic or environmental factors such as stressful events. The results of this study aid in the understanding of how potential environmental risk factors may increase the risk of developing NMOSD.
