Bruce Cree, MD at the University of California San Francisco discusses some of the early symptoms of neuromyelitis optica spectrum disorder (NMOSD) that neurologists, ophthalmologists, and gastroenterologists should be aware of to speed up the diagnosis of this rare central nervous system disorder.

One of the biggest challenges NMOSD patients face when seeking diagnosis is that the diease presents very similarly to other diseases, such as multiple sclerosis, or problematic  gastrointestinal conditions. This can lead to  a delayed diagnosis, extending the period of time a NMOSD patient goes without treatment. Therefore Рlike any disease Рearly diagnosis is crucial, according to Dr. Cree.
