Brain development disorders in children linked to common environmental toxin exposures -- ScienceDaily

Exposures of pregnant women and children to common
thyroid-hormone-disrupting toxins may be linked to the increased
incidence of brain development disorders, according to a review
published in Endocrine Connections. The review describes how
numerous, common chemicals can interfere with normal thyroid hormone
actions, which are essential for normal brain development in foetuses
and young children, and suggests a need for greater public health
intervention.

Autism four times likelier when mother's thyroid is weakened

 Pregnant women who don't make nearly enough thyroid hormone are nearly 4 times likelier to produce autistic children than healthy women, report scientists from the Houston Methodist Neurological Institute and Erasmus Medical Centre in an upcoming Annals of Neurology.
