Yes, yet another ADHD thread. I mistakenly omitted a previous “diagnosis” of ADHD when I initially got my 3rd class medical years ago. Recently when reviewing my records, I found the diagnosis and realized that I screwed up. I’m trying to get this corrected and have stopped flying. Would it be best to call the FAA and tell them or get everything done prior to getting a new medical (cogscreen, records, etc.) and just apply for a new medical?
