I find really interesting the description of the ADHD assessments, both on the post and on the comments. It seems like everyone had one or two tests plus some interview at most.

My diagnosis came after I had multiple tests and interviews in a 2 month period, including interviews with my mother and my partner. Sure I was also diagnosed with autism, but the final report given to me was so complete and descriptive of my pains, symptoms and the impact on my day-to-day functioning that it just couldn't be made with a single interview.
