Also that there was more awareness of the actual symptoms and problems it causes?
While we're at it it would be good to dispel the myths and stereotypes that create a lot of stigma and lack of belief around the condition..
I was diagnosed in my early 40s having spent my whole life believing I was just a bit useless and incapable, which has really affected my self esteem over the years.
Turns out it's an actual difference in my brain, certain areas develop differently causing executive function difficulties. This is thought to be caused by problems with the levels of available dopamine in the brain. So people with ADHD love things which give a dopamine hit, e.g. mobile phones, video games and in some cases high risk behaviours and addiction.
The stereotype of the little boy in class misbehaving and bouncing off the walls is so unhelpful. Girls and women are the most underdiagnosed due to this. ADHD can be classed as several different presentations : primarily inattentive (daydreamer, distracted) primarily hyperactive-impulsive (fidgety, can't sit still, very talkative, but also internal "busy mind") and combined type (some of both sets of symptoms). (Very basic summary).
Things that have been hard for me:
*Anxiety, which comes from having a million thoughts in my head. Thoughts can be worries, ideas, thinking about something I said last week and always a pervading sense that I've forgotten something really important because..
- Working memory problems. It's really, really hard to remember things if I don't write them down or set a lot of reminders. Also some of the million thoughts that pop up can push out that important appointment I'm going to after work.
*Procrastination. I want to do the thing but starting it ("task activation") is so ridiculously hard. I then go to avoiding the bad feeling by doing something else. Maybe something useful, often Facebook doom scrolling. :(
*Time blindness. People with ADHD have a really poor sense of how much time has passed and also difficulty estimating how much time a task will take and if they therefore have time to do it. I feel humiliated when I think of all my years of being late for work no matter how early I got up and not being able to explain it.
*Talking too much, blurting out things I didn't mean to, accidentally interrupting people.
*Impulse buying - how much money I've wasted i don't know.
*Emotional over reaction. I tend to snap easily. Especially if I'm busy and interrupted, partly because of forgetting what I was doing and also ...
*Inability to filter out distractions. Noises, people talking, all those thoughts again.
*Getting stuck on something, commonly known as hyperfocus. This can be anything, I must finish a book even if it's almost 2am, research buying stuff for 4 hours, occasionally tidying out a cupboard, but I might not get everything put away after starting. 
I'm sure I've forgotten a lot, but I'm feeling quite strongly about raising awareness of this since starting medication and suddenly feeling almost capable of things for a change. I'm calm, I can start boring or hard tasks more easily and can see them through. Not perfect but better.
This is only true while the medication is in my system, but even during those hours it's a revelation.
I feel like I can be a better parent, partner, employee.
I now have an explanation for many things that have happened in the past. I was constantly told I was capable of better, needed to try harder and I knew myself I understood what to do, it just never seemed to happen the way I wanted.
I'm not "out" at work as having ADHD, but I'm really considering it as I imagine all the other women, men and children wondering why the fuck they keep having the same problems every day.
I came across a description of ADHD by accident, which I think is really common. Or people are diagnosed right after their children - it's common for it to affect several members of a family.
So if some mumsnetters can help with busting some myths and misinformation I'm sure it'll be a bonus.
I've "met" many people on here recently who are in the same situation as me, bumping into them on various ADHD related threads.
Feel free to improve or add to my totally rambling, too long summary/rant.
