How common is peripheral neuropathy in children with celiac? My daughter's peripheral neuropathy started at age 2 before we even knew she had celiac.
There are known associations between celiac disease and many neurologic disorders, one of which is peripheral neuropathy (PN). A study published this year by researchers at Columbia University Medical Center found that, of 400 adults with celiac disease, almost 40% of the patients had peripheral neuropathy. However, it is important to note that these were patients who self-reported peripheral neuropathy. In other words, they were not examined by or officially diagnosed by a neurologist. This was a significant limitation of the study.
In terms of PN in children with celiac disease, only two studies have ever been published. One found 2 out of 27 children with celiac disease who had PN (or 7%). The other study found 1 patient out of 835 children with celiac disease who had PN (or 0.1%). There is so much variation in the literature regarding the occurrence of PN in celiac disease! This is because most of the available studies are small (from a scientific research perspective). We definitely need more studies and bigger studies in children to determine exactly how common peripheral neuropathy is.
