Autism prevalence and outcomes in older adults.
We still lack basic health and suicide data for autistic adults over 50—start screening and tracking now.
01Research in Context
What this study did
Robison (2019) wrote a narrative review. The author looked at what we know about autistic adults over 50.
The paper is a call to arms. It says we lack basic numbers on how many older autistic adults exist, how often they get sick, and how often they die by suicide.
What they found
The review found a gap. We have almost no data on autism in adults past mid-life.
Without those numbers, we cannot plan health services or check if programs work.
How this fits with other research
Nijhof et al. (2025) extends this gap into hard data. They show autistic adults land in hospital and die from COVID-19 at rates 30–60 % above the general public.
Fradet et al. (2025) also extends the worry. They link poor sleep to suicide risk in autistic teens and adults, giving a target the 2019 review asked for.
Forbes et al. (2023) seems to contradict the doom story. Their young-adult cohort had low independence but mental-health scores close to UK norms. The difference is age: Gordon looked at 20-somethings; Elder warns about 50-plus. Risk rises with age, so both can be true.
Why it matters
If you serve autistic adults, treat Elder's gap as a red flag. Track health and suicide risk past age 50. Use Dewy's COVID data to push for medical follow-up. Use L's sleep link to add sleep checks to safety plans. Start counting now, because what we measure we can fix.

03Original abstract
Recent studies of mortality, illness, and suicide among autistic adults paint an alarming picture. Autistic people appear to die much earlier than the general population, and they seem to be far more vulnerable to a surprising range of medical problems. Suicide and depression seem far more common than in the general population. If correct, that suggests an older autistic population in silent crisis, with few if any supports. If so, older autistic people should be a focus for public health and human service agencies. But is the picture complete? Autism researchers ask for answers, identifying problems and their scope. This article discusses the limitations of our adult autism knowledge, and the challenges we will face studying adults. Researching and ultimately serving older autistic adults presents a unique set of problems that have not yet been addressed by scientists or clinicians. Autism Res 2019, 12: 370-374 © 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Public policy toward autistic people is driven by data. Most autism data to date have been derived from and about children, because autism tends to be identified and supported in the public school system. This has created a public perception of autism as a childhood problem. In fact, autism is a lifelong difference or disability, and recent studies suggest serious overlooked concerns for autistic adults. This commentary discusses how we have evaluated adult autism so far, limitations of our knowledge, and how we might evaluate adult needs going forward. The commentary makes a case for specific new adult prevalence and outcome studies to inform public policy.
