Roughly one in six children in the U.S. has one or more developmental disabilities, ranging from a learning disability to a serious behavioral or emotional disorder. Scientists believe that the amount of toxic chemicals in the environment that cause developmental and neurological damage are contributing to the rise of physical and mental effects being found in children. Studies show childrenâ€™s developing organs create â€œearly windows of great vulnerabilityâ€ during which exposure to pesticides can cause great damage. In the U.S., requirements for testing pesticides and other chemicals for potential developmental and learning disorders are minimal.
A developing brain is much more susceptible to the toxic effects of chemicals than an adult brain. During development, the brain undergoes a highly complex series of processes at different stages. Interference from toxic substances that disrupt these processes can have permanent consequences. That vulnerability extends from fetal development through infancy and childhood to adolescence. Research has shown that environmental toxicants, such as pesticides, at low levels of exposure can have subclinical effectsâ€”not clinically visible, but still important adverse effects, such as decreases in intelligence or changes in behavior.
What are the Forms of Specific Learning Disability
An appropriate definition describes the many forms known as processing disorders.
These processing disorders may impact
â€¢ vision (visual processing disorder, failure of eyes to send accurate information to the brain),
â€¢ hearing (auditory processing disorder, failure to correctly interpret information received by the ears),
â€¢ coordination of the muscles of the body with other senses (sensory motor integration),
â€¢ the ability to stay focused in the classroom (attention), and
â€¢ the ability to form and verbalize ideas (conceptualization). http://www.beyondpesticides.org/health/
