I was diagnosed ADD (or what would now be called inattentive ADHD) in my 30s. But the testing results were not clear, in part because I'd developed a lifetime of coping mechanisms and skills that allow me to behave in non-ADHD ways through force of will. If I look back at my primary school report cards, they are a mixture of both gifted and below-average performance with teacher comments like "Does amazing work when he applies himself".

That sudden lack of motivation or drop in performance on tasks that we previously excelled at is also classic ADHD.

Anxiety is often a comorbidity, stemming from a feeling of inconsistent failure and lack of control. Though my understanding is that anxiety may be more present in women sufferers of ADHD where the disease manifests differently than in men.

All of this to say that you may feel like a DSM definition of ADHD doesn't map onto your experience, but that may be because you're an adult who has a lifetime of adaptation.

I'll be 60 in a few months and looking back I've tended to think that anxiety has been the main thing that held me back in my career, but I can also relate to the post above where they say they do great in the early days of a job/project, but as time goes on find it more and more difficult to stay engaged. I guess I would think this is caused by anxiety in my case, but now I'm wondering if maybe there isn't more going on. I also got mixed results in school: gifted in subjects I liked, average/below averages performance in subjects I didn't care much about. So maybe there's always been a bit of an issue, but I also tend to think that it's much worse since the advent of smart phones - I think there may be a lot of us who were either not ADHD or just on the edge of being ADHD that have been pushed over the edge by being constantly connected.

Yes, my understanding is that some people present with anxiety (and/or depression), and that anxiety will become the focus of treatment by their doctor or psychologist, when in fact the anxiety stems from the undiagnosed ADHD. For these people, treating the anxiety alone isn't very effective, compared to getting an ADHD diagnosis and treatment plan that also has a positive impact on the anxiety symptoms.

Anecdotally I've seen this scenario play out in my own family.
