Here is the link to the study:

"Dr. Robert Mann, senior scientist at CAMH and co-principal investigator said this latest study extends previous findings from the research team about the association between TBI and mental health and addiction issues.
These new data suggest a significant association between ADHD and TBI," Dr. Mann said. "We see that adults with TBI are more than twice as likely than those without to report symptoms of ADHD."
I don't doubt there's an association, but I do doubt that it accounts for all the cases of ADHD. I think some of it is innate or heritable, or there wouldn't be differences by family and ethnic group.
I also wonder whether it might perhaps be a trait that was helpful when we were all hunter-gatherers but that is less helpful now when functioning in modern society requires hours of sitting still and concentrating in classrooms.
