Trump asked her: "So what's going on with autism?".
This "tremendous amount of increase" that Trump referred to during the round-table meeting is completely inaccurate, according to the CDC facts.
President Donald Trump recently told a group of educators there was "a tremendous amount of increase" in the prevalence of autism.
WHY IT MATTERS: While Trump during one primary debate insisted he was "totally in favor of vaccines", he has subscribed in the past to theories unsupported by scientific evidence linking vaccines to autism.
Studies have shown an almost three-fold increase in autism diagnoses amongst American special education programs, as well as a spike in autism spectrum disorder diagnoses, the website stated.
"President-elect Trump. asked me to chair a commission on vaccine safety and scientific integrity", he said.
Researchers are still trying to figure out what exactly accounts for the rise in autism cases that is not an artifact of changes in reporting methods and screening.
New York Magazine's Jesse Singal, who first highlighted the president's claim, interviewed autism expert and NeuroTribes author Steve Silberman about the remarks.
"Quenneville responded that she has, and noted her school "has shifted its population" to accommodate more students with autism".
Trump responded, "What's going on with autism, when you look at the tremendous increases, it's really - it's such an incredible - is it really a terrible thing to watch the tremendous amount of increase".
Quenneville is the only parent or teacher in the roundtable that Trump seemed to take interest in immediately, asking her multiple questions as people were still introducing themselves.
There's a good chance you've met someone in their 60s, 70s, or 80s who might have been diagnosed with autism if they'd been born today but were just seen as exhibiting unusual behavior in their childhood.
Part of what fuels the anti-vax movement is this misperception: If not too long ago autism wasn't a "crisis" (advocates for autistic people are not fans of such phrasing, for understandable reasons), but today it is, then it makes sense to look for a scapegoat like vaccines.
TRUMP: "Tremendous increases. really a terrible thing to watch the tremendous amount of increase". "Do you have any idea?" "And you're seeing it in the school?"
The CDC published a report in 2016 that found that the prevalence of autism spectrum disorder was consistent with the rate from two years prior, at 1-in-68 children.
Trump said that he thought the ratio numbers were lower and added: "Maybe we can do something".
The exchange, as seen in a video released by the White House, revealed that the president believes autism rates are rising in the U.S. The definition of autism has changed over the years, making it hard to make an apples-to-apples comparison of rates, and autism figures vary widely across different states.
The Post pointed out that in 2000, government data put the prevalence of autism at about 1 in 150 children.
It's problematic to compare autism rates over the last three decades because the criteria for diagnosing autism have changed with revisions of the Diagnostic and Statistical Manual (DSM).
Labeling also is an issue, as parents became more likely to seek out the increasing services for autism and related disorders that are available in schools and other settings.
"Due to inconsistencies in diagnosis and how much we are still learning about autism, the most recent DSM (DSM 5) only has one diagnosis, autism spectrum disorder (ASD), which encompasses each of the previous four disorders", according to the foundation.
