It's mainly for the depression - - but I've found since starting the medication that I've been able to focus far better than before. There are some studies around where they tested this drug for ADHD with kids.

I've tried a few other drugs for both ADHD and depression / anxiety over the years, but this one seems to be the sweet spot between helping with everything. Hardly scientific, but it's my experience.

I should note that at lower doses mirtazapine (remeron) helps with insomnia. For me, I'm on a higher dose (45mg) where this isn't the case.

To add to this; If any of you with ADHD have found that you're miraculously killing at Scrabble or Boggle after a few drinks, being on this medication is a similar feeling. It's as if the anxiety or whatever is the noise and the medication filters that out.
