Some psychiatrists consider it a trait and not a disorder.
It should only be "treated" if it affects one's life negatively (which it often does in the modern world, unless you are guerilla herding sheep / living a generally interesting life). So, people "born that way" can suffer more in modern world than they did say 20 or 200 years ago.
There is evidence that medication helps.
There is an interesting book on the topic: _ADHD: A Hunter in a Farmer's World_
Disclosure: I am diagnosed as an adult with ADHD ("primarily innatentive" subtype).
