Autism Spectrum Disorder has no single known cause, although research indicates that it is most likely caused by a mix of genetic and environmental factors. Although there is little parents can do to prevent or forecast autism in their children, there are a few risk factors. This article investigates the genetic and environmental factors that may raise the likelihood of autism, as well as additional risk factors.

Environmental considerations

Environmental influences are more likely to produce autism in people who are already predisposed to it or have the aforementioned gene mutation. Environmental factors such as chemical interactions and viruses may induce autism in people who are genetically prone. This does not necessarily imply that someone with a genetic tendency would develop autism as a result of these environmental exposures; rather, it raises the risk.

Genetic factors

Even though there is no single known cause of autism, studies reveal that it most likely runs in families. Certain genetic variations may be responsible for autism, and if either parent has these genetic mutations, the child is more likely to inherit autism (even if the parents with the gene do not have autism). This is most likely because these mutations have an impact on early brain development.

More than 100 genes on several chromosomes may be relevant to autism in its many manifestations. The type of gene that is compromised may be responsible for the severity and type of symptoms. Even if neither parent carries this gene mutation, the embryo can develop it on its own. Many people with these genetic abnormalities do not have autism or any of its symptoms. This genetic mutation does not, by itself, indicate that autism is the cause; rather, it raises the risk.

Risk factors have increased.

Either parent’s advanced age could result in an autistic child. Exposure to certain chemicals and medications by the mother during pregnancy can also raise the chance of autism. Alcohol and anti-seizure medications are examples of these drugs and chemicals. Back-to-back pregnancies, or pregnancies separated by less than a year, increase the risk of autism.

Factors unrelated

Even though this is a hotly discussed topic, there is no scientific evidence to imply that vaccination causes autism.

It is critical for parents to understand that there is no one cause of Autism Spectrum Disorder and that it cannot be foreseen or prevented. Although a family history of autism and certain chemical exposures can raise a child’s chances of having autism, it is never definite that these factors will cause autism. 

Risk factors have been reduced.

Prenatal vitamins containing folic acid are advised for most pregnancies and may help reduce the incidence of autism. Although there is no way to avoid having an autistic child, a healthy lifestyle for the mother during pregnancy (frequent check-ups, good eating habits, regular exercise, abstaining from drugs and alcohol) can all assist in reducing the risk and having a healthy baby.
