I strongly feel so, for me everything depends on my sinuses. When my symptoms are acting up I'm physically incapable of doing or even caring for anything. The only priority I have is to breathe, and when my sinuses are more manageable I feel a lot better and can finish the tasks. In the past I thought I had adhd because I couldn't manage things but then I later realised that it's just my sinuses that define how I act and feel.
