Symptoms of Neuromyelitis Optica Spectrum Disorder

Neuromyelitis optica spectrum disorder (NMOSD) can be mistaken for multiple sclerosis (MS) because symptoms can be similar.

Symptoms of NMOSD depend on the areas of the nervous system involved. They often develop suddenly and may include:

• Sudden vision loss
• Eye pain
• Muscle weakness
• Paralysis
• Sensory loss
• Bladder or bowel dysfunction
• Nausea
• Vomiting
• Hiccups

Attacks are often severe and can result in lasting disability if not treated promptly.
