Autism is a complex neurological disorder that affects the way a person communicates and interacts with other people. It is estimated to affect 1 in 59 children in the United States, and it is more common in boys than girls. While there is no single cause of autism, there are several factors that can increase a person’s chances of being diagnosed with autism.
The first factor is genetics. People with a family history of autism are more likely to have autism themselves. Studies have found that certain genetic mutations can increase the risk of developing autism. For example, mutations in the SCN1A gene have been linked to autism spectrum disorder.
Environmental factors can also increase the chances of a person developing autism. Exposure to certain environmental toxins, such as lead, mercury, and polychlorinated biphenyls, during pregnancy can increase the risk of autism. Other environmental risk factors include maternal infections during pregnancy, advanced maternal age, low birth weight, and premature birth.
Research has also suggested that certain medical conditions can increase the risk of autism. These include fragile X syndrome, tuberous sclerosis, and certain seizure disorders. It is important to note that these conditions do not cause autism, but they may increase the risk of a person developing autism.
Finally, certain lifestyle factors can increase a person’s chances of developing autism. These include smoking during pregnancy, drinking alcohol during pregnancy, and drug use during pregnancy.
Overall, there are several factors that can increase a person’s chances of developing autism, including genetics, environmental factors, medical conditions, and lifestyle factors. It is important to be aware of these factors so that people can take steps to reduce their risk of developing autism.
