I looked up Neuro Inflammatory Disease. Google suggested right away that I was searching for Neuroinflammatory as one word. It seems there are many diseases under this category - such as Parkinson's, MS, Alzehimer's. My search turned up a book on Amazon called "Migraine: A Neuroinflammatory Disease?"
Here is a link to where this term was mentioned back in 1997. "The Blood-Brain Barrier in Neuroinflammatory Diseases"

Perhaps when you saw it, they were saying RSD is a form of Neuroinflammatory Disease, not that they would replace the name RSD or CRPS with Neuroinflammatory Disease.

Although I use "RSD" - I don't like that it has the word sympathetic in it. Makes me wonder if when hearing that, people think we are folks who fake a disease to get sympathy. I had RSD before "CRPS" became popular - and it is hard for me to change. My doctors have all called it RSD - unless they made a written report or letter for me, and then they called it CRPS.
