This article makes a point about mis-diagnosis. It's an important point. Look at dyslexia. There are a bunch of different reading disabilities, but school children are mostly tested for dyslexia. If they have dyslexia they get a bunch of help. If they have some other reading disability, well, it's hit or miss whether they get the help or not. So some people with mild dyslexia are geting copious help, while other people with moderate reading disabilities are not getting any help.

This is why accessibility is important. The people who meed the help and who need the assisstive tech might not be able to get it. So, please, do remember accessibility.
