The theory of disease for ADD/ADHD in children has explanatory power, which means that the understanding must be at least partially correct.
It's impressive that many children outgrow their ADD, and that temporary use of amphetamines during development can help them outgrow it, so they don't regularly take drugs as adults.
Some kids don't outgrow it, and continue to medicate as adults. That's also fine, if it helps, it helps.
What doesn't add up is people with new problems with executive function that start as adults, and suspiciously as they have more control over their screen time, and more money to spend on technology and apps. They get an amphetamine prescription, which definitely helps, but they also get a bad explanation. Something like: genetics, or a story about how their brain was better in the ancestral environment or whatever. Doesn't explain the onset of the condition, doesn't explain why it became a problem completely after development.
