There is an increase in diagnosed ADHD in adults, with uncertainty about whether this represents previously undetected childhood ADHD or new onset due to modern environmental factors.

“The other thing that we are seeing a lot nowadays is increased levels of ADHD in adults and there's some question as to whether or not those adults had ADHD that went undetected during their childhood or whether or not ADHD is now cropping up in adulthood due to the way that we are interacting with the world in particular smart phone use, the combination of email, text, real-world interactions, multiple apps and streams of media and social media all coming in at once trying to manage life.”
