I have always considered my ADD/ADHD a blessing and Gods gift to Humanity that everyone should strive for. But I am also old, children weren’t coddled back then or drugged and we never got any participation trophies.
The study was done using Medicaid as the provider. Wouldn’t that imply that the children were the offspring of people in the poverty level? Otherwise the children would have been covered by Premera,Regence or some other paid program.
