Previous underreporting may play some role in the observed growth, sure. However, the article dates from 2017 and the author's prediction, that "Future estimates will be based on DSM-5 criteria [approved in 2013]—which may lower autism rates" has not come true. The prevalence since then has increased from 1 in 68 to 1 in 54 (CDC). Thus, the increased awareness may be a contributing factor, but it is unlikely to be the only factor.Investigation is fine, your assertion that use of a particular drug in pregnancy is implicated, while ignoring a million and one other factors known and unknown, is not. Take a read of The Real Reasons Autism Rates Are Up in the U.S. which discusses previous under reporting (or perhaps current over reporting depending on your point of view) and the related genetics articles.
