Find Out What is the Cause of Autism

By George Alarcon

Autism is a spectrum disorder which means that there are varying degrees of autism. One person can be mildly affected and may be able to function in society while another individual may be profoundly affected to such a degree that there is no hope of independent living. With such varying degrees of this disorder, one might expect that there are several underlying causes which increase the chance and severity of autism.

So far, research suggests more than one possible cause for the disorder although there does appear to be a genetic component. Siblings of those with autism have an increased chance of developing the disorder. However, the chance of identical twins developing the disorder is not 100%. Because of this, it is thought that environmental factors also play a role in autism. A lot more research is still required to arrive at more certain conclusions on this theory.

The presence of Thimerosal in vaccinations, particularly in the Measles, Mumps and Rubella vaccine, has long been thought to cause some cases of autism. The preservative has been removed from the vaccine due to this belief but many parents remain unconvinced that the vaccine is safe. Parents have the right to choose not to vaccinate their children--if they feel their children may suffer a serious health risk. Other parents argue that autism may be caused by the overload on the immune system by the current vaccine schedule. Many children with autism suffer from asthma, other respiratory ailments and impaired immune systems. It is now hypothesized that exposure to a virus either as a fetus or as an infant might also cause the damage to the immune system which results in autism; of course, this is only a mere theory which tries to search at the core cause of autism.

The diet of the pregnant mother might also contribute to autism. Studies have suggested that retinoids, retinoic acid or too much Vitamin A could increase the chance of a fetus developing autism. It is also believed that environmental toxins or pollutants may contribute to the development of autism although no definitive link has yet been found. An increase in regional cases suggests an environmental trigger and much is being done to study this possibility. Of course, this also is only a mere theory at this time.

The diets of the children have also come under scrutiny. Many autistic children have difficulty digesting gluten, found in wheat, barley and oat products, and casein which is found in dairy products. The elimination of these proteins helps to improve the autistic behaviors in some children although consuming these products does not appear to cause autism. For now, research is focused finding the gene or genes responsible for causing autism with the hope that genetic testing can identify those at risk for the disorder. With early therapy and intervention, the effects of autism can be minimized. So if you plan to have children in the future it may be wise to know the early symptoms of autism in order to identify them as soon as possible. - 17268
