Celiac.com 02/09/2006 – After a review of the medical literature, researchers have concluded that many cases of schizophrenia are related to celiac disease or gluten intolerance, and can be successfully treated using a gluten-free diet. Like celiac disease, schizophrenia affects approximately 1% of the population. It is considered one of the top 10 causes of disability worldwide. In many studies the researchers found that in a subset of patients a drastic reduction or total elimination of schizophrenic symptoms occurred after they were treated with a strict gluten-free diet. Based on this the researchers believe that a gluten-free diet may serve as a "safe and economical alternative for the reduction of symptoms in a subset of patients." They conclude: "Large-scale epidemiological studies and clinical trials are needed to confirm the association between gluten and schizophrenia, and address the underlying mechanisms by which this association occurs."
