Trying to understand one another goes both ways. It would also be thoughtful and compassionate if her H could try to learn to think about break's feelings and what she would like to do. Rather than giving his opinion, he could try, "What can I do to help?" or "I'd like to learn more about ADHD. Where's a good place to start?"....or something along those lines to show he cares.
By saying he doesn't think she has ADHD, he's completely disregarding what she is going through and feeling. That's not very supportive of a spouse.

That's a foreign language to him. You'd think they'd learn by the EXAMPLE we give as spouses, but they don't see our care of them as applying to them and how they should care for us. He wasn't given an example by his parents. When his mom came home from the hospital with the new baby, the first thing his dad said is what are you fixing for lunch?
But I'm going to extend myself a little and think if I can explain it some way that gets through...maybe he will be a little more compassionate. It's hard to do this work when if he would BE a little more compassionate I could do this work!!! AAAHHH!
