Growing number of chemicals linked with brain disorders in children
Toxic chemicals may be triggering the recent increases in neurodevelopmental disabilities among children — such as autism, attention-deficit hyperactivity disorder, and dyslexia — according to a new study from Harvard School of Public Health (HSPH) and Icahn School of Medicine at Mount Sinai. The researchers say a new global prevention strategy to control the use of these substances is urgently needed.
The report was published online February 15, 2014 in Lancet Neurology.
“The greatest concern is the large numbers of children who are affected by toxic damage to brain development in the absence of a formal diagnosis. They suffer reduced attention span, delayed development, and poor school performance. Industrial chemicals are now emerging as likely causes,” said Philippe Grandjean, adjunct professor of environmental health at HSPH.
The report follows up on a similar review conducted by the authors in 2006 that identified five industrial chemicals as “developmental neurotoxicants,” or chemicals that can cause brain deficits.
