MDD a not so common symptom of ADHD?

My psychiatrist diagnosed me with ADHD. I often forget or lose things I have a hard time focusing especially on boring things.I fidget. I have emotional regulation issues.

The main problem and main reason why I visited the doc. tho is MDD. I have been doing it since my earliest memories. I'm 25 now. My fidgeting is mainly connected to my MDD.

I told my doc this and other stuff which are not so relevant to the topic. His conclusions is that my MDD is an not very common symptom of ADHD

What do you guys think?
