New evidence hints at the role of gut microbiota in autistic spectrum disorder
“recent neuroscience studies have found that the biological makeup of the gut could contribute to some of the most characteristic symptoms of ASD. More specifically, experiments on mice suggest that the pathway between gut bacteriaand the central nervous system can affect social behaviors.”…“The recent findings gathered by this team of researchers seem to confirm previous […]
Research finds potential mechanism linking autism, intestinal inflammation
“When a mother experiences an infection during pregnancy and her immune system produces elevated levels of the molecule Interleukin-17a (IL-17a), that can not only alter brain development in her fetus, but also alter her microbiome such that after birth the newborn’s immune system can become primed for future inflammatory attacks.”
Processed Foods May Hold Key to Rise in Autism
“the UCF scientists discovered how high levels of Propionic Acid (PPA), used to increase the shelf life of packaged foods and inhibit mold in commercially processed cheese and bread, reduce the development of neurons in fetal brains.”
Prenatal and infant exposure to ambient pesticides and autism spectrum disorder in children: population based case-control study
Findings suggest that an offspring’s risk of autism spectrum disorder increases following prenatal exposure to ambient pesticides within 2000 m of their mother’s residence during pregnancy, compared with offspring of women from the same agricultural region without such exposure. Infant exposure could further increase risks for autism spectrum disorder with comorbid intellectual disability.
First biomarker evidence of DDT-autism link
“The investigators found the odds of autism with intellectual disability in offspring were increased by greater than twofold for the mother’s DDE levels in the top quartile. For the overall sample of autism cases, the odds were nearly one-third higher…” “
Aluminium in brain tissue in autism
“These are some of the highest values for aluminium in human brain tissue yet recorded”
Everyday chemicals may affect brain development, including foetal IQ
“Our paper, published on March 7 in Scientific Reports, shows that young tadpoles exposed to a mixture of common chemicals at concentrations routinely found in human amniotic fluid not only modified thyroid hormone signalling but also reduced the total number and size of neurons and inhibited tadpole movement.”
Exposure to specific toxins and nutrients correlates with autism risk
“Our study suggests that metal toxicant uptake and essential element deficiency during specific developmental windows increases ASD risk and severity, supporting the hypothesis of systemic elemental dysregulation in ASD. Independent replication in population-based studies is needed to extend these findings.”
Biologists control gut inflammation by altering resident bacteria
“The fact that we could alleviate inflammation by adding back a single key bacterial strain, suggests that it could be useful as a probiotic for inflammatory diseases,” said Rolig, who, along with Eisen, is a scientist in the National Institutes of Health-funded Microbial Ecology and Theory of Animals Center for Systems Biology, known as the […]
Ketogenic diet improves behaviors in a model of autism spectrum disorder
“…these studies suggest a broad utility for metabolic therapy in improving core ASD symptoms, and support further research to develop and apply ketogenic and/or metabolic strategies in patients with ASD.”
