Hi Joanna
Sorry I can't answer your question about whether NLD neuropathy is ganglionopathy but I can say that full body nerve damage can be from more than one cause. I have full body neuropathy - from my eyelids to between my toes and pretty much everywhere in-between.
Like Healthgirl, no-one has mentioned ganglionopathy to me (not that they've mentioned much at all). Mine is presumed to be auto-immune as I have another chronic auto-immune condition. Mine was also aggravated by the antibiotic Flagyl (Metrondiazole).
Thanks Cliffman for that useful link.
