The scientific literature on the link between gluten and autism is mixed and there is no substantial research on in utero causality. There have been too few adequately designed, large-scale controlled studies and clinical trials to state whether the diet is effective. A small, single -blind study has documented fewer autistic behaviors in children fed a gluten-free, casein-free diet, but noted no change in cognitive skills, linguistic ability, or motor ability. This study has been criticized for its small sample size, singleblind design which may have skewed results on the basis of a "parent placebo effect". A 2006 double-blind short-term study found no significant differences in behavior between children on a gluten-free, casein-free diet and those on regular diets. A long term double-blind clinical trial sponsored by the National Institute of Mental Health ran from 2004 until November 2008; as of July 2009, results are not yet available.

Gluten sensitivity is also seen as a a genetically inheritable problem. Though limited studies have been conducted some people have seen the gluten free diet improve their life while handling problems such as,Parkinson’s disease, Multiple sclerosis, Seizures, Cognitive problems, Type 2 and Type 1 diabetes, Down syndrome, Rheumatoid arthritis, and other medical conditions.  While treating other conditions people need to be aware that some medications contain gluten. With gluten being an ingredient in medication it is highly advised that a person on the gluten free diet consult a doctor and check the labels of medications before beginning a medication.
