It becomes a disorder when it&#x27;s detrimental to regular life. Many who have ADHD are incredibly frustrated at their apparently lack of willpower. It&#x27;s not the rest of society pressuring them to come closer to the norm, they want to get themselves to the norm too. Perhaps it is overdiagnosed and overmedicated in some settings, (I realize you&#x27;re trying to get conversation away from the more black and white physical conditions... myopia has always seemed a good analogy though, so I&#x27;m going to continue using it temporarily) but you wouldn&#x27;t tell a shortsighted person that they&#x27;re not that far off of the bell curve, just squint your eyes once in a while to make up for missing detail.
