Yikes. Thanks for posting this, @silentsaturn91 .
The reporting (and the press release) are wildly overstated. “Neurobiological Origin of Attention Deficit Disorder Discovered” is just a made-you-click title, and the claim they they have “confirmed the biological origin of the disorder” is a wild leap that is not backed up by the study.
The researchers used a genetically altered mouse that exhibited some symptoms that “remind us of adult patients suffering from one of the forms of ADD.” And therein lies the true finding. They meddled with mice and managed to get some symptoms that in some vague mousy ways, seem similar to ADHD in humans.

So why the shamelessly claimy press release? These animal models are big money-makers, since they are used in drug-development research. Could it be that the university hopes to market their mouse model as the new animal ADHD model and a make a fortune? While we could certainly use an improvement over the current critter, we are still a long long way from finding the cheese.
