Here in US, it is rather simple to get an ADHD designation. My partner did it so she could get access to the meds that help her with her daily life all through the insurance plan. They definitely are a benefit to have around the house when we really need to get stuff done.
All 3 of my siblings got ADHD designations when we were children, but to this day I've never had a clinical designation of my own. Twice I spoke with a psychiatrist, but both times after their exam, they would not provide a conclusion diagnosis. Who knows if this was some crazy insurance scheme, or if that was truly their medical opinion, I'll never know. What I do know is that I've gotten here alright without much caffeine, nicotine, or alcohol, so I must be doing some things alright.
