Specifically, there was “a 43% increase in the rate of adults being newly diagnosed over the 10-year period,” said Dr. Michael Milham, vice president of research at the Child Mind Institute in New York, who was senior author of the study. He added that the rise might be the result of ADHD being diagnosed more frequently.  “In short, I believe the clinical community is recognizing that ADHD is not just a disorder of childhood and we cannot turn a blind eye to its negative outcomes,” Milham said.
