A recent study published that was conducted in the Netherlands found more children with autism lived in a high tech IT sector. These findings follow a theory called the "hyper-systemizing" theory of autism. This theory proposes that people with autism have a strong desire to understand the workings of systems, the researchers said. Such skills are valued in IT-related fields, including engineering, physics, computing and mathematics. The outcome of the study was the need to study more information in this area.
Autism Spectrum Disorders (ASD) Causes
3 AnswersChantal Sicile-Kira, Autism, answeredA common pattern among moms is to wonder what they did wrong: drinking or taking medications during pregnancy, exercising too much, allowing the child to be vaccinated? This guilt add to an already stressful situation. Please don’t feel guilty about your child's condition. You did not cause his autism and you have done the best you can at any given time.
1 AnswerThe Dan Marino Foundation answeredThe causes of PDD-NOS are still unknown. There is a strong belief in the medical community that that the disability’s origin is genetic and/or biological and affects brain function, but specific biological mechanisms remain unclear. There is a possibility that more than one variable could be responsible for the different symptoms that are present in those individuals with PDD-NOS.
There are no factors in a child’s upbringing that are responsible for PDD-NOS. Parents do not cause PDD-NOS.

Very little is known about the risk factors that cause autism. A new study called EARLI is a network of research sites that will enroll and follow 1,200 mothers of children with autism at the start of another pregnancy and document the newborn child’s development through three years of age. The EARLI Study will examine possible environmental risk factors for autism and study whether there is any interplay between environmental factors and genetic susceptibility.
According to the Centers for Disease Control and Prevention, approximately 1 in every 110 children has an Autism Spectrum Disorder (ASD). Autism is the fastest growing developmental disability in the country; however, little is known about what causes it.

1 AnswerColeen Boyle, PhD, MS, Public Health, answered on behalf of Centers for Disease Control and Prevention (CDC)We do not know all of the causes of ASDs. However, we have learned that there are likely many causes for multiple types of ASDs. There may be many different factors that make a child more likely to have an ASD, including environmental, biologic, and genetic factors.
Most scientists agree that genes are one of the risk factors that
can make a person more likely to develop an ASD. Children who have a sibling or parent with an ASD are at a higher
risk of also having an ASD. ASDs tend to occur more often in people who have certain other
medical conditions. About 10% of children with an ASD have
an identifiable genetic disorder, such as Fragile X syndrome,
tuberous sclerosis, Down syndrome and other chromosomal
disorders. Some harmful drugs taken during pregnancy have been linked with
a higher risk of ASDs, for example, the prescription drugs
thalidomide and valproic acid. We know that the once-common belief that poor parenting
practices cause ASDs is not true. There is some evidence that the critical period for developing ASDs
occurs before birth. However, concerns about vaccines and
infections have led researchers to consider risk factors before
and after birth.

Autism Spectrum Disorder is a neurological disease that presents with
- severe and pervasive impairments in reciprocal social skills,
- deficits in language skills,
- presence of stereotypic behaviors, restricted interests or restricted activities.

Twin and family studies strongly suggest that some people have a genetic predisposition to autism. Identical twin studies show that if one twin is affected, there is a 90 percent chance for the other twin to be affected too. Several studies are in progress to determine the specific genetic factors associated with the development of autism spectrum disorder (ASD). In families with one child with ASD, the risk of having a second child with the disorder is approximately five percent, or one in twenty. This is greater than the risk for the general population. Researchers are looking for clues about the genes that contribute to this increased susceptibility. In some cases, parents and other relatives of a child with ASD show mild impairments in social and communicative skills or engage in repetitive behaviors. Evidence also suggests that some emotional disorders, such as manic depression, occur more frequently than average in the families of people with ASD.

1 AnswerWilliam Stillman, Health Education, answeredThere is no prenatal test to determine autism in a fetus in utero; however, as various environmental factors are under research investigation for autism causation, the wise mother will closely monitor what she eats, drinks, breathes, and topically applies to her skin as she should to ensure the overall health of her baby no matter its way-of-being in the world.
According to the CDC, research does NOT show any link between the type of mercury in vaccines and autism. They also point out that the mercury was taken out of childhood vaccines in 2001 and the rates of autism have continued to climb.
