Diane,
Those are good examples. Like anything, though, you need to sometimes establish alternatives for a good idea when the disability is other-than-expected. A PPT presentation that works very well for a student with ADHD may be problematic for a student who is blind unless he/she has some way to access the key points included on the slide while the lecture is ongoing. If you are reading those points as you go along, no problem. If you are just using them behind you to summarize, you need to think about how a blind student will be able to follow.
