Look up any videos on the brain scans of those with ADHD. The brain is functioning differently in an empirically measurable way, than a typical brain. The brain lacks the normal activity in the executive functioning area in the front of the brain. This isn't made up, it's measurable against a control. It was an evolutionarily advantageous trait 500,000 years ago in the plains of Africa when we were hunter/ gatherers but now this trait causes problems in our modern world.
