It's important that NMO is correctly diagnosed. It can sometimes be confused with multiple sclerosis , which also affects the brain and spinal cord and has similar symptoms. However, the treatment is different.
Aneurology specialist will discuss your symptoms and medical history with you.
You'll have a magnetic resonance imaging (MRI) scan of your brain and spinal cord. Some people with NMO (up to 60%) have lesions on their brain and spine, which are different to the lesions of someone with MS.
A blood sample will be taken and tested for aquaporin-4 antibodies.
A lumbar puncture is another test you may have. A sample of cerebrospinal fluid (CSF) is taken from the spine using a hollow needle that's inserted into the lower part of the spine.
