Does environment affect autism?
Due to the progress of autism in recent decades, a wide range of studies have been done to identify the etiological factors of autism. It has been found that genetic and environmental factors are both involved in autism pathogenesis.
What is the root cause of autism?
We know that there’s no one cause of autism. Research suggests that autism develops from a combination of genetic and nongenetic, or environmental, influences. These influences appear to increase the risk that a child will develop autism.
Who is at high risk for autism?
Children born to older parents are at a higher risk for having autism. Parents who have a child with ASD have a 2 to 18 percent chance of having a second child who is also affected. Studies have shown that among identical twins, if one child has autism, the other will be affected about 36 to 95 percent of the time.
What are some of the factors that can lead to autism in a child?
What causes autism?
- having an immediate family member with autism.
- genetic mutations.
- fragile X syndrome and other genetic disorders.
- being born to older parents.

What is the best treatment for autism?
Studies have shown that medication is most effective when it’s combined with behavioral therapies. Risperidone (Risperdal) is the only drug approved by the FDA for children with autism spectrum disorder.
Which parent carries the gene for autism?
Autistic children may inherit DNA mutations from their fathers. There is no one gene that, when mutated, causes autism. But over the past decade, researchers have identified hundreds of gene variations that seem to affect brain development in ways that increase the risk of autism.
Do babies with autism sleep well?
Children with autism are more likely than typical children to have had problems falling asleep as infants, according to a new study1. These infants also have more growth in the hippocampus, the brain’s memory hub, from age 6 to 24 months.
Does time out work with autism?
