Is There Evidence of a D D Ae?

Is there evidence a d d is a product of our era, that it did not exist in a less work and finance oriented period? As for instance, did cansian economics not trigger a d d to to the point that neo liberalism does to day? Soi i think it's hard to prove definitively. But certainly, i mean, rates of a d d ae going up. Certainly rates of diagnosis are going up. And there's a lot of under diagnosis going on as well. Like i said, the process specifi adolts is completely inappropriate for people with a dd a.
