For far longer than it should be needed, a vast majority of us in the autism community have said that genetics may account for a far bigger role in autism than any of the other factors being explored. Now, a study of over 2 million people in several countries is saying similar…to the tune of 80%.
This study not only included 2 million people, but covered a 16 year span. There have been many studies confirming the same findings, but none have been this huge. And while the study is not perfect (what study is?), it is leading researchers to a new field of exploration and questions regarding the role genetics play in autism, along with the role “environmental” factors may still play.
But how does one look for a history of autism in their family, especially if there are no concrete diagnosis to be found (which is often the case, particularly in minority families)?
The key lies in education; being familiar with the symptoms and listening to that instinct that something may not be adding up on the developmental milestones.
The key lies in communication: talking to the professionals (doctors, psychiatrists, etc.) and speaking up about your concerns.
It also lies in understanding: knowing what autism is, is not, and looking at it with empathy instead of sympathy.
The links to the study and an article about the study are below.
There is also a link to my first FREE autism class happening on August 3 in South Florida, which will give you a head start on all of those aforementioned keys.
