Developmental Disorders Resulting From Toxic Chemicals
This work in writing seeks to identify developmental disorders that result from toxic chemicals and to answer as to whether these disorders are possible to prevent and if so how they may be prevented. Alternatively, if these disorders are not possible to prevent this work will answer the question of why they are not preventable.
Household & Environmental Exposure to Toxic Chemicals
The work of Graff, Murphy, Ekvall and Gagnon (2006) reports that in-home toxic chemical exposures have been identified as being the reason for developmental delays in some children. Toxic chemical exposure to lead and mercury are reported in the study as being the cause of some developmental disorders.
Contributing to brain development in children are factors such as: (1) gene expression; (2) heredity; (3) socioeconomic factors; (4) stress; (5) drugs; (6) nutrition; and (7) chemical contaminants. (Gupta, 2008) Gupta additionally states that there are "multiple ways by which chemicals can disrupt neurological development such as influencing gene expression, protein pathways and hypothyroidism. It is a well-established fact that a child's nervous system is more sensitive to chemical exposures compared to an adult nervous system." (2008)
There are stated to be a wide range of toxic chemical sin the environment that are linked to neurodevelopmental disabilities which affect approximately three to eight percent of the total 4 million babies born in the U.S. every year. Exposure to toxic chemicals may be through industrial accidents, occupational exposure, suicide attempts and accidental poisonings. The number of toxic chemicals that cause neurotoxicity is stated to exceed 1000. (Gupta, 2008, paraphrased)
II. Prevention
Prevention is possible although there are many challenges presented in the prevention of exposure of children to toxic chemicals. In order to prevent toxic chemical exposure in children the effort required is one of great magnitude and one that will require the participation of many actors at many levels throughout society and the world at large.

Autism and Dementia Description of Autism Spectrum Disorder and Dementia Behavioral Criteria for Autism and Dementia The Incidence Rates and Causes Options for Treatment Based on Theoretical Models Description of Autism Spectrum Disorder and Dementia Autism Spectrum disorder is a neurodevelopmental disorder which is essentially a brain dysfunction that has the potential to affect emotion, learning ability and memory that gradually comes to light as an individual grows up. This is generally evident in children and
Psychologists, especially Freudians, considered experiences undergone at the tender, early childhood age to be crucial to social, psychological and mental growth. Newer studies reveal that even late-childhood experiences are influential, capable of altering a child's developmental course. A majority of contemporary psychologists discuss sensitive, rather than critical, phases, which are phases when an individual is found to be particularly reactive towards or equipped to handle particular experiences. Hence, while childhood
When processed by a transglutaminase enzyme, it can interact with immunological cells and produce cytotoxic inflammation. In autism, it is believed that peptides from gluten and casein cross the intestinal microvillus barrier and enter the blood stream. They also cross the blood-brain barrier. In the brain, certain amino acid sequences of these peptides compete with natural peptides, which bind to opioid receptors. These receptors are G-protein receptors in cell
This dramatic event followed the revelation that Wakefield had accepted money from lawyers representing parents who had filed lawsuits claiming that the MMR vaccines had caused autism in their children. Some of these children were even part of Wakefield's original study. (Schreibman, 2005) This disclosure may have laid some doubts to rest but is still not enough to answer the question whether there is actually a link between MMR and
Toxins Cause Autism? The Jury is Still Out Nicholas Kristoff's writes about the issue of environmental toxins and autism, and the link between exposure to these toxins and the rise in autism spectrum disorders. Autism comprises a clinically heterogeneous group of disorders -- collectively referred to as "autism spectrum disorders" (ASD) -- that share common features of impaired social relationships, impaired language and communication, and repetitive behaviors or a narrow range
mystery of autism has long eluded people in the medical and education profession. Millions of people around the world suffer from the disorder and seek treatment for it each year. Since the discovery of the disorder a plethora of research has been conducted but there is still very little that is known about the origins of autism or effective treatments to combat the effects of the disorder. The purpose of
