Autism diagnoses have jumped by nearly eight times in just the last two decades, a new study finds. Although many may associate autism with children and men, researchers at the University of Exeter say doctors are seeing this rise in cases more often among women and adults.
Their study reveals that, between 1998 and 2018, autism diagnoses across the United Kingdom have skyrocketed by 787 percent. Researchers reviewed the medical records of nine million patients to reach these findings.
Specifically, the team discovered that cases of Asperger’s syndrome — a form of autism with no link to intellectual disabilities — were rising before health officials retired that particular diagnosis in 2013. Asperger’s now falls under the greater diagnosis of autism spectrum disorder (ASD).
What’s causing this increase?
Study authors suggest that the near-800-percent rise in autism cases has more to do with increased reporting and better screening methods than an actual increase in the number of people living on the autism spectrum. Despite their findings, researchers say they still can’t rule out the possibility that more people are developing ASD in recent years.
“As there is not really a plausible reason why autism should increase more in adults and females our study suggests the change is probably due to increased identification, and not more people with neurodevelopmental disorders per se,” says lead author Ginny Russell in a university release.
