A gluten-free diet for "schizophrenia positive for antigliadin antibodies (AGA IgG)"

Short post alert...

"This feasibility study suggests that removal of gluten from the diet is associated with improvement in psychiatric and gastrointestinal symptoms in people with schizophrenia or schizoaffective disorder."

So said the findings reported by Deanna Kelly and colleagues [1] as the conference abstract [2] of their study finally hits the peer-reviewed science literature (see here).

As per my previous musings on this study, this was the "first double-blind clinical trial of gluten-free versus gluten-containing diets in a subset of patients with schizophrenia who were positive for AGA [anti-gliadin antibodies] IgG." Results were interesting insofar as "participants on the gluten-free diet showed improvement on the Clinical Global Impressions scale... and in negative symptoms." Net result: encouraging findings with the need for more study; also with a nice focus on effect sizes too...

'Nuff said.
