AYER, Mass. — Connor Murphy walked in circles around his dad, then flopped down on the kitchen floor, got up and walked in circles again.
His dad turned the 9-year-old's repetitive behavior into a chance to connect. ''Want me to pick you up?'' Matthew Murphy asked, lifting, tickling and spinning with his son.
Such spontaneous moments are common in the Murphy household, which revolves around the needs of Connor and his twin brother Ronan, who both have profound autism.
''They're going to need 24-7 care for the rest of their lives,'' their father said. ''Life will be a challenge for them, and we have to prepare them as best we can.''
Autism rates have been rising for decades, and two of the main reasons for the increase have, in a strange twist, taken some of the focus off helping people with round-the-clock needs. The diagnosis of autism spectrum disorder, adopted in 2013, is now very broad, including many people with low support needs. Also, better awareness of the condition has helped many more children get diagnosed than in the past — and most of those cases are relatively mild.
At the same time, the Trump Administration is promoting unproven and debunked claims about what causes autism, which experts say muddles efforts to understand the condition and fuels misinformation that threatens public health, even as officials funnel more money into research.
There's now a growing push to separate profound autism — in which people need constant care for life, have a certain level of intellectual disability and are nonspeaking or minimally verbal — into its own diagnosis. The hope is that it would help ensure that people like Connor and Ronan get the support and services they need and that research includes them.
In the United States, an estimated 1 in 31 children have autism spectrum disorder. Researchers estimate around a quarter have ''profound autism,'' a term introduced in 2021 by a group of experts, the Lancet Commission, to describe people most disabled by the developmental condition.
