Neuromuscular diseases associated with antigliadin antibodies. A contentious concept.

Many neurological syndromes associated with antigliadin antibodies have been published. The most frequent are cerebellar ataxia and peripheral neuropathy. Such cases are reported under the title of gluten ataxia or of coeliac neuropathy. However, associations do not prove cause. Herein, a short review is made of the literature and the author's personal experience. Many unsolved questions remain. Gluten sensitivity is probably an immunological response in genetically susceptible individuals with or without enteropathy. Antigliadin antibodies are present in healthy adults, in some idiopathic ataxias and neuropathies. A gluten-free diet is effective on gastrointestinal but not on neurological symptoms. Whether antigliadin antibodies are elevated is more of a waiting classification than a definite diagnosis. Finally, the relationship between antigliadin antibodies and neurological diseases is very weak.
