Some data suggest an association between autism and celiac disease. However, to date, these data are limited and inconclusive. This was a retrospective study of 382 preschool age children in Italy (age range 18-72 months) who had been diagnosed with autism spectrum disorder (ASD). All had undergone blood screening tests for celiac disease. In this group, the overall prevalence of celiac disease was 2.62%, which is statistically significantly higher than the rate in the general population. The authors state that if these results can be replicated, these findings suggest the importance of screening for celiac disease regularly among young patients with autism spectrum disorder.
