Hello Purple Paisley and Welcome to NeuroTalk.
Feel free to visit the Multiple Sclerosis (MS) forum. NMO was once thought to be a vairant of MS, but that is no longer the case. NMO and MS are separate diseases and have different treatment, though their symptoms are very similar.
For information and support on NMO you might try The Guthy Jackson Foundation
http://www.guthyjacksonfoundation.org/
You can log in to Spectrum and will find a wealth of information and support for NMO.
Best wishes
