Toxic Chemicals Linked to Brain Disorders

Recently, researchers from Harvard School of Public Health and Icahn School of Medicine at Mount Sinai found that toxic chemicals may be linked to the increased number of neurodevelopmental disabilities among children.


In the current day and age there are many more diagnoses of children with neurodevelopmental disabilities than in the past.  These disorders include autism, ADHD, and dyslexia, and result in common symptoms such as reduced attention span, weak social skills, and delayed development.


The report published by Phillippe Grandjean and Phillip Landrigan is a follow up to their 2006 publication identifying five chemicals that could be considered “neurotoxicants” as they may cause these brain deficits.  This current study gives more information about the long term effects of the previous five chemicals, as well as identifies new ones – the most recognizable being manganese, fluoride, and DDT which is found in pesticides.


The team postulates that there are many more potential neurotoxicants that must be tested so that proper safety measures can be taken.  The team also suggests that the known neurotoxicants must be controlled in a different manner to prevent further neurodevelopmental disabilities.
