Could you be autistic and not know? I, and many other autistic adults with a late diagnosis of autism, will tell you – YES!

The current model of autism diagnosis is predicated on the assumption that autism traits will make themselves seen in early childhood. In fact, it is often thought of as a childhood disorder. But the amount of late diagnosed autistic adults means that clearly this model is missing something and instead of an outside-in approach we need to start thinking about an inside-out approach – listening to the internal experiences of autistic people, rather than having neurotypical researchers describe what they think they see.
