Genetics is a clear part of autism, but not all of the genetic risk is inherited. Some of the genetic changes that lead to autism are de novo, which means mutations in the egg or sperm.
Autism Spectrum Disorders (ASD) Causes
The causes of autism spectrum disorders (ASD) have been hotly debated. While scientists suspect that both genetics and environment play a role, there is no certainty about what's behind this group of neurological disorders. Research continues, searching for the causes. Find answers to your questions about autism spectrum disorder and autism risk factors with expert advice from Sharecare.

The 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.

Ogden Regional Medical Center answeredSee All 7 AnswersVaccinations have frequently been front and center as the suspected reason for the increasing number of children diagnosed with autism. The trend started in 1998 when British surgeon Andrew Wakefield and 12 colleagues published a study suggesting that the measles, mumps and rubella (MMR) vaccination caused autism. After much more research involving more than 25 million children, the original study was retracted in 2010. Further, Wakefield and colleagues were found guilty of deliberate fraud following a journalistic investigation. To this day, there is no credible medical research linking autism and vaccinations.

Jumo Health answeredSee All 2 AnswersAnybody can get ASD, but it is more likely to occur in boys. For every girl with ASD, there are four boys with it. One in 100 people in the world has autism, and 1 in 68 people born in the USA has autism. That's more than 3.5 million people.

William Stillman , Health Education, answeredSee All 2 AnswersThere 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. -

Joane Goodroe , Nursing, answeredAccording 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.

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.
