George Osborne, the Shadow Chancellor, has been criticised for appearing to refer to Gordon Brown as "autistic". There was a similar complaint from a viewer of a BBC TV programme over the weekend, when a presenter also used it as a term of political description.
It's a reminder that certain conditions can be wrongly characterised in the public mind - or even if they are accurately characterised, their use can be insensitive. Other examples include "Tourettes" for being foul-mouthed, "schizophrenic" for having a split personality. And it's a reminder perhaps that people who are affected by those conditions, either directly or indirectly, can be irritated when they are carelessly used as journalistic shorthand.
