I'm not sure if this article has been discussed before, but it appeared in the November 2015 edition of Columbia Public Health. It Take Guts: Scientists Delve Into the Role of Intestinal Microbes in Autism. https://www.mailman.columbia.edu/public-health-now/news/it-takes-guts The article discusses efforts at Columbia University by Drs. Bresnahan, Hornig, Susser, Lipkin et al., to investigate the possible involvement of the microbiome in some cases of autism, as discussed earlier in their May 2015 paper in JAMA Psychiatry: Association of maternal report of infant and toddler gastrointestinal symptoms with autism: evidence from a prospective birth cohort. http://www.ncbi.nlm.nih.gov/pubmed/25806498 ...and in this 2011 paper in PLoS One, by Drs. Williams, Hornig, Lipkin, et al.: Impaired Carbohydrate Digestion and Transport and Mucosal Dysbiosis in the Intestines of Children with Autism and Gastrointestinal Disturbances http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0024585 Obviously, this is also intriguing in light of their interest in the mircobiome and its possible relationship to ME/CFS.
