The majority of studies on heritability of autism spectrum disorder (ASD) have suggested that heritability is up to 80-90%. However, a new study on Swedish children suggests that the role of environmental factors has been underestimated and that they may be of equal importance to genetic factors. The study from researchers based in the Karolinska Institutet in Sweden, King's College London, and Mount Sinai in the USA, is published in the Journal of the American Medical Association (JAMA).

Researchers at Karolinska Institutet have developed a new screening tool to facilitate the diagnosis of Autism Spectrum Disorder in adults. The test is presented in the scientific journal Molecular Autism and is unique in that researchers have, as part of their evaluation, compared the group diagnosed with Autism Spectrum Disorder with psychiatric patients.

Mice whose mothers suffered from infection or inflammation during pregnancy are at greater risk for developing behaviors similar to those seen in people with autism spectrum disorders (ASD). Now, researchers reporting in the Cell Press journal Cell on December 5 have linked those neurodevelopmental symptoms in the mice to changes in the bacteria living in the animals' guts. What's more, when researchers treated those animals with bacteria found in the healthy gut, a number of behavioral abnormalities including anxiety-like behavior largely went away.

Clinicians have long known that early identification of an autism spectrum disorder (ASD) improves a child’s long-term health outcome as well as the family’s ability to cope with disease. But Latino children are diagnosed with ASDs less often and later — an average of 2.5 years later — than white children and have more severe symptoms at the time of diagnosis. The reasons behind these disparities have been poorly understood, and no studies have investigated pediatricians’ perspectives on this inequity — until now.

Plant-based diets are healthy. Plants are high in flavonoids. So flavonoids are healthy. At least that's the reasoning of many manufacturers of flavonoid-based nutritional supplements. But a University of Colorado Cancer Center study published this week in the journal Hormones & Cancer shows that may not be the case. Flavonoids tested in the study affected the endocrine system in ways that in one case promoted cancer and in another repressed it.

One in 88 children has been diagnosed with an autism spectrum disorder (ASD) in the United States, according to the Centers for Disease Control and Prevention. A new study by a University of Missouri researcher found that many children with ASD also experience anxiety, chronic gastrointestinal (GI) problems and atypical sensory responses, which are heightened reactions to light, sound or particular textures. These problems appear to be highly related and can have significant effects on children’s daily lives, including their functioning at home and in school.
