We also recap that research on older autistic people has lagged behind other age groups (from Mason et al. (2022; AiA)) - only 0.4% of autism research focuses on old age, but in recent years it has become a rapidly changing field of research.

We start by raising the issue that autism in midlife and old age are often overlooked. Using data from O'Nions et al. (2023; Lancet), we estimate that 89% of middle-aged autistic people and 96% of older autistic people in the UK are likely undiagnosed.

I had a proud supervisor moment yesterday supporting my wonderful former BSc student, Andreea. Her work on sleep and mental health in middle-aged and older autistic adults was chosen from 100s of projects to be presented that this research event hosted by the Houses of Parliament. She was fantastic!
