Good Idea! I'll be interested if any pop up.
For reading comp the best thing I found with my own son (HS'ing my 9yo ADHD-c kiddo) is Charlotte Mason 'Narrating'.
In a nutshell, you put every sentence (if you're starting out where where we were!), then paragraph, then scene, then chapter "in your own words". Process takes a few months. 'In your own words' changes kid to kid. Some literally just explain what's happening in their own words. Some write. Some draw. My son is a performer... so he acted them out. For more on narration... here's a great link: http://simplycharlottemason.com/timesavers/narration/
For the sensory processing issues that often happen with adhd, one of the common things that happens is either auditory (not being able to put spoken word to picture in your mind) or visual (not being able to turn written word into image). Without the mental 'movie' that happens reading or listening can be like a neurotypical person trying to memorize (seriously, try to actually LOOK at each letter and number and phrase and commit them to memory).

Yeah. My mind grinds to a halt as well. Now imagine pages and pages and pages of such things. But learning to gradually create the 'movie' that happens when reading can be life altering.
