Ysserb, good to hear. I looked up a couple of research articles and I see that ADHD diagnoses increased from 6% to 10% of all kids between 1990s and 2018. (14% boys and 6% girls; poor 13%, rich 9%; up to 11y.o – 8%, 12-17 13%).
The first ref below mentions that UK rates are also increasing while being lower, shyly not mentioning the numbers .. UK estimates I can find are 3-5% of children as of 2013 (estimates in population, not actually treated) – so, something strange might be happening all across US – school incentives? bad parenting? overdiagnosis?
