The only person I know who has done this semi-openly is the author Elizabeth Moon. Her son has autism which she believes is partly a sensory processing disorder (but that's probably an simplification of her position)

Unfortunately she was most open about this in a web forum which is now defunct. But various blogs may be of interest:

Her live journal (entries tagged autism) https://e-moon60.livejournal.com/tag/autism

The blog on the (fiction) book she wrote from the PoV of a character with autism: http://www.speedofdark-thebook.com/blog/?cat=46
