Arizona State University’s Walter Cronkite School of Journalism and Mass Communication’s [National Center on Disability and Journalism](http://ncdj.org/styleguide/) provides a style guide that explains the common terms related to disabilities and their usage. The style guide points which items follow the AP style guide and which don’t.
It offers tips on when to use certain words and when to avoid others. Do you say, “Confined to a wheelchair?” (No) Do you ever use the word “Handicapped,” which many consider offensive? (Only in reference to laws and regulations such as “Handicapped Parking.”)
Great reference for writers and for people to share with others who wonder about the same thing.
