As far as the reading problems go, I recommend her checking out Irlen Lenses (expensive) or an Irlen Overlay (cheap) for her son.

Sensory wise for me the Irlen Lenses kept the words from wandering all across the pages of my books. Even though I was an avid reader, it was getting impossible for me to read text starting in my early 20's. The Irlen Overlay was the first time since my teens that the words stopped moving so much. Additionally, the words flowed easily again for me instead of me constantly repeating the same word, sentence, or paragraph.

Supposedly the Irlen Lenses help dyslexics, but since I don't have that problem I can't guarentee anything there.

I got my Irlen Lenses after trying out an Irlen Overlay for two weeks and it made it possible to read my Masters degree Engineering books again.

I spent a lot of extra time studying compared to my fellow students and many times it was due to having to reread everything so many times.

Some kids learn better while moving and touching things. Sitting in a chair still is litterally hell for them. I didn't have this problem, but other kids I grew up with did. They were smart, but because they would do anything to get out of the chairs they often flunked classes.
