This comes from the UCAS disability codes, which as a consequence what we end up using within institutions, and is a self definition from the students themselves. If the applicant / student considers that "unseen" is most appropriate to their circumstances, rather than the other options on offer, then that is what they can opt for. And which is often interchangeable with "disability not listed above" (code 9).

Or do different institutions just make up their own definitions? Thanks Paul Loader
