Data from a new CDC report, which was analyzed by "The New York Times," shows 11% of all school-age children have received an attention deficit hyperactivity disorder diagnosis at some point in their lives - a 16% increase since 2007.
Nearly one in five boys in high school has been diagnosed with ADHD, and nearly two-thirds of children with a current diagnosis of ADHD are taking medication for it, like Ritalin or Adderall.

CNN's Dr. Sanjay Gupta explains the limitations of the CDC's phone survey that found 1 in 50 children has autism, and talks about why a report released by the same government agency last year put that number much lower at 1 in 88.
"I think in part it depends how you count these cases," says Sanjay. "I don't think there's been that significant an increase, but this is more reflective of increased awareness, an increased diagnosis."
