I think you are compiling a list of articles etc on FND. This link may be of interest but maybe you've found it already. scholar.google.co.uk/scholar
There is also a book called Landmark papers in Neurology. Dr Jon Stone (my Consultant) has a chapter in there - 4 and specifically 4.2 on my particular form of FND - dissociative/conversion.
I'm still trying to track down an article written by a female doctor at the Mayo Clinic in California. She was talking about non-invasive brain stimulation. I raised this with Dr Stone but he reckoned that there was no solid basis for it and more of a placebo effect.
