--celiac/gluten sensitivity IS a documented cause of neuropathy, and can happen either primarily through direct cross-reactivity of nerves to gluten peptides and/or as a result of the kinds of nutritional deficiencies that people with malabsorption are prone to.

The Gluten File (https://sites.google.com/site/jccglu...eralneuropathy) is full of information and links on this--and googling the names Russell Chin, Norman Latov, Peter Green, Hadijvassiliou, etc. will also bring up a lot of information and papers regarding this.
