As with many other disorders, the development of autism depends not only on what occurs before birth in terms of genetic influence, but also fetal development inside the mother’s womb. Some risk factors for autism spectrum disorder may be maternal hypothyroidism, drug or alcohol use, or infection, but it is key to note that such circumstances are also associated with a variety of other disorders as well (Rutter, 2005). Any such toxins and intrauterine infections could contribute to the development of autism, as well as atypical brain development, dopamine abnormality, and maternal/paternal age.
