“The relationship of the antibodies to the clinical course of mania was analyzed by the use of regression models. Individuals with mania had significantly increased levels of IgG antibodies to gliadin, but not other markers of celiac disease, at baseline compared with controls in multivariate analyses … Among the individuals with mania, elevated levels at follow-up were significantly associated with re-hospitalization in the six month follow-up period.”
“Individuals with recent-onset psychosis and with multi-episode schizophrenia who have increased antibodies to gliadin may share some immunologic features of celiac disease, but their immune response to gliadin differs from that of celiac disease.”
“In the same way that the celiac iceberg illustrated the illusion that intolerance to wheat is rare, it is possible, even probable, that wheat exerts pharmacological influences on everyone. What distinguishes the schizophrenic or autistic individual from the functional wheat consumer is the degree to which they are affected.”
