Examples of biological or medical explanations attributed to ASD are hereditary factors (Gona et al, 2015;Heys et al, 2017), infectious disease (Gona et al, 2015;, an accident (Al-Dababneh, Al-Zboon, & Baibers, 2016;Minhas et al, 2015;Shaked & Bilu, 2006;Tilahun et al, 2016), complications during pregnancy or birth (Al-Dababneh et al, 2016;Gona et al, 2015;Heys et al, 2017;Shaked & Bilu, 2006;Shyu, Tsai, & Tsai, 2010;Tilahun et al, 2016) or malnutrition (Gona et al, 2015;Heys et al, 2017). In the USA the most common perceived causes reported by parents are genetics/heritability and environmental risk factors, including heavy metals, food, pesticides, pollution and other exposures (Chaidez et al, 2018;Zuckerman, Lindly, & Sinche, 2016).…”
