Attention-deficit/hyperactivity disorder, known as ADHD, has become more common among U.S. adults, according to a study published in the JAMA Network Open medical journal.

Why it matters: The study reflects in part increasing awareness about ADHD in adulthood among clinicians and patients, Dr. Hanna Stevens, a University of Iowa professor who has previously conducted research on ADHD, told CNN.

  • "A trend we have seen in other research studies is that there is an increase in people seeking psychiatric care generally, which may also reflect a positive trend in reduced stigma to talking [about] psychiatric symptoms and seeking appropriate help for them," Stevens said to CNN.

By the numbers: There was "a 43% increase in the rate of adults being newly diagnosed over the 10-year period" from 2007 to 2016, the study's senior author Dr. Michael Milham told CNN.

  • The number of diagnoses rose from 9.43 per every 10,000 people in 2007 to 13.49 per 10,000 people in 2016, according to the study.
  • Prevalence of the disorder among adults increased from 0.43% in 2007 to 0.96% in 2016.

Yes, but: The study's limitations include that it only included adults seeking care within Kaiser Permanente North California, CNN reports.

  • The study falls short in "understanding of ADHD in patients who are not a part of a health system such as Kaiser Permanente, which includes very low income individuals," Stevens told CNN.

What matters from President Biden's town hall with CNN's Anderson Cooper at Baltimore Center Stage on Thursday, via Axios night owl Hans Nichols:

The biggest headline: Biden is jettisoning the corporate tax increases that White House officials have insisted, for the past 10 months, are wildly popular across the country. He admitted he doesn't have the votes.

Trump, your 2024 GOP nominee

Former President Trump is telling most anyone who'll listen he will run again in 2024 — and poll after poll shows the vast majority of Republicans would gladly cheer him on and vote for him. 

Why it matters: Trump is the heart, soul and undisputed leader of the Republican Party and will easily win the nomination if he wants it, the polls make unmistakably clear.

How smartphone cameras became the best cameras

Illustration: Sarah Grillo/Axios

For years, the smartphone has been the most convenient camera, and in recent years it has also become the easiest and most versatile camera. But this year's high-end smartphones have taken things to a new level — capturing images that would be either tough or impossible even with a high-end digital camera.

Between the lines: Traditional cameras have the advantage of bigger sensors and better lenses, but smartphone cameras are rivaling and even surpassing them by tapping computational power.
