What’s so important to know is that frequently people with NMO are misdiagnosed with MS because many of the symptoms are familiar.
And what usually happens, is that good-meaning neurologists prescribe a disease-modifying drug (DMD) to treat the “MS.”
It just makes, sense, right? I mean, after all, NMO was, until recently, considered an aggressive form of MS. Both diseases are relapsing and remitting, with symptoms that are usually separated over several years.
So “proactive” neurologists were prescribing treatments trying to slow the progression of the disease.
These days, the medical and scientific communities have learned that DMDs could have dire consequences for the misdiagnosed person.
The wrong treatment could cause a severe exacerbation which could be life-threatening.
Although NMO is a rare disease—far more rare than MS—and is also a demyelinating disease like MS, scientists now know that NMO is typically severe and far more aggressive, leading to disability much more rapidly. They now understand that these two diseases exist separately, their symptoms overlap.
Most people “present” (I just despise that term) with classic optic neuritis, longitudinally extensive myelitis, with a positive NMO-IgG test result.

With an MRI test result, here are the most common findings:
- Swollen optic nerves (bilateral) and T2 lesion seen with contrast
- Three or more T2 lesions on the spinal cord, or some type of “involvement”
- Absence of lesions on the brain, but if/when they do appear, these are different from lesions found in the brains of people with MS
Unlike MS, treatment is lacking although Rituxan is demonstrating some promising findings.
