Neuromyelitis Optica Spectrum Disorder
- Diagnosis
NMOSD can be diagnosed by a combination of detailed medical history, clinical examination and tests. Some of these tests include:
- Detecting AQP4-IgG antibody in the blood helps to differentiate between NMOSD and MS as well as other similar immune-mediated neurological conditions
- Lumbar puncture (spinal tap)
- To remove a small amount of fluid from the spinal column
- This test might help to differentiate NMOSD from MS or other conditions which can mimic NMOSD
- Magnetic Resonance Imaging (MRI)
- Imaging of the brain, optic nerves and spinal cord to detect areas of inflammation or damage
