For a medical student or an intern who has only encountered this diagnosis in passing, what do we actually mean by intellectual disability? How do you determine severity, and roughly how common is it?

Thanks, Gavin.

Those are really great questions.

I'd like to kind of first start by acknowledging that there are people with lived experience of intellectual disability who may be listening in on their podcast and want to acknowledge them as well as their families and carers, and also recognize the valuable contributions that that make to Australia and global society.

So intellectual disability is not taught extensively in the undergraduate medical curriculum, so we, we use the DSM, DSM-V specifically when we make a diagnosis of intellectual disability.

This is often made by a psychologist or a psychiatrist.

And really there are kind of three main parts of the diagnosis.

Can you tell me a little bit about that for me, please?
