I can relate to everything that this article says, but I suspect this is true of every single person with a mentally challenging job.
HN is full of developers complaining about open offices and useless meetings; do all of them have ADHD? Otherwise, what's the difference between a ADHD developer and a regular developer?
I _do_ have specific body problems that make my work harder, such as a very strong noise sensitivity and a circadian rhythm that requires me to sleep longer than the average person. Dealing with those specific problems did much more than throwing my hands in the air and yelling "ADHD".
Instead of a 2000-word article that might have been generated by AI, I would just follow these three points.
1. Sleep 9–10 hours every night.
2. Strong exercise regularly.
3. Work somewhere quiet and pleasant.
