Yes, I agree. I think he is cautious because his patient population includes a lot of adults with addiction issues (past or present) and he is very suspicious of drug-seeking behavior. But it seemed like a huge generalization to make, "I don't prescribe stimulants for adults unless they were diagnosed with ADHD as a child." As sara76 wrote, girls are less apt to be diagnosed as children. So women may present disproportionately as adults, looking for help as their coping becomes inadequate. With this provider's approach, some adults who could be helped will not get it. He is a family practitioner, so maybe he makes referrals to specialists if he is in doubt. I think there is nothing wrong with taking a cautious approach and trying Wellbutrin or Strattera as a first course of treatment, but if that doesn't work, what does he do? Hopefully, he refers. I will be talking to him again in a week, and I may ask him about this.
