Watch 10 Toxic Chemicals which are causing Autism and Learning Disabilities

What is Autism? What Causes Autism?

Autism is known as a complex developmental disability. Experts believe that Autism presents itself during the first three years of a person's life. The condition is the result of a neurological disorder that has an effect on normal brain function, affecting development of the person's communication and social interaction skills.


People with autism have issues with non-verbal communication, a wide range of social interactions, and activities that include an element of play and/or banter.


Learning disabilities


These are problems that affect the brain's ability to receive process, analyze, or store information. These problems can make it difficult for a student to learn as quickly as someone who isn't affected by learning disabilities.

There are many kinds of learning disabilities. Most students affected by them have more than one kind. Certain kinds of learning disabilities can interfere with a person's ability to concentrate or focus and can cause someone's mind to wander too much. Other learning disabilities can make it difficult for a student to read, write, spell, or solve math problems.



New Research- Top 10 Toxic Chemicals Causing Autism and Learning Disabilities

 
An editorial published in the prestigious journal Environmental Health Perspectives calls for increased research to identify possible environmental causes of autism and other neurodevelopment disorders in America's children and presents a list of ten target chemicals including which are considered highly likely to contribute to these conditions.
Philip Landrigan, MD, MSc, a world-renowned leader in children's environmental health and Director of the Children's Environmental Health Center (CEHC) at Mount Sinai School of Medicine, co-authored the editorial, entitled A Research Strategy to Discover the Environmental Causes of Autism and Neurodevelopment Disabilities, along with Luca Lambertini, PhD, MPH, MSc, Assistant Professor of Preventive Medicine at Mount Sinai and Linda Birnbaum, Director of the National Institute OF Environmental Health Sciences.


The editorial was published alongside four other papers - each suggesting a link between toxic chemicals and autism. Both the editorial and the papers originated at a conference hosted by CEHC in December 2010. The National Academy of Sciences reports that 3 percent of all neurobehavioral disorders in children, such as autism spectrum disorder (ASD) and Attention Deficit Hyperactivity Disorder (ADHD), are caused by toxic exposures in the environment and that another 25 percent are caused by interactions between environmental factors and genetics. But the precise environmental causes are not yet known. While genetic research has demonstrated that ASD and certain other neurodevelopment disorders have a strong hereditary component, many believe that environmental causes may also play a role - and Mount Sinai is leading an effort to understand the role of these toxins in a condition that now affects between 400,000 and 600,000 of the 4 million children born in the United States each year.
A large number of the chemicals in widest use have not undergone even minimal assessment of potential toxicity and this is of great concern, says Dr. Landrigan. Knowledge of environmental causes of neurodevelopment disorders is critically important because they are potentially preventable. CEHC developed the list of ten chemicals found in consumer products that are suspected to contribute to autism and learning disabilities to guide a research strategy to discover potentially preventable environmental causes. The top ten chemicals are:

  1. Lead

  1. Methyl-mercury

  1. PCBs

  1. Organophosphate pesticides

  1. Organochlorine pesticides

  1. Endocrine disruptors


  1. Automotive exhaust


  1. Polycyclic aromatic hydrocarbons

  1. Brominated flame retardants

  1. Perfluorinated compounds

In addition to the editorial, the other four papers also call for increased research to identify the possible environmental causes of autism in America's children. The first paper, written by a team at the University of Wisconsin - Milwaukee, found preliminary evidence linking smoking during pregnancy to Asperger's disorder and other forms of high-functioning autism. Two papers, written by researchers at the University of California - Davis, show that PCBs disrupt early brain development. The final paper, also by a team at UC - Davis, suggests further exploring the link between pesticide exposure and autism.
