I recently felt the need to correct someone for describing one of their colleague's children as 'having autism' - as opposed to 'being autistic' - but since then I've noticed a lot more examples of people describing others and themselves as 'having autism' so I'm starting to wonder if it's just a matter of personal preference or whether it's a regional difference or an Americanism that's spread - or whether it's another example of a lack of awareness of what autism is?
Thoughts?
