Abstract

Research on ageing in autism has sharply increased following a number of influential publications that highlighted the lack of knowledge in this area. However, much of the research on autism ageing has inadvertently treated all people aged over 50 as a homogeneous ‘older adult’ group, overlooking important distinctions between midlife (40–64 years) and old age (65+ years). Midlife is marked by complex role management, career pressures, health changes and identity development, while old age often involves retirement, shifts in priorities, physical and cognitive changes, and planning for less independent living. Recognising midlife and old age as distinct life phases is essential to accurately characterise the lived experiences and needs of autistic adults across the latter part of the lifespan. This letter makes conceptual and methodological suggestions that autism researchers should align with established ageing frameworks by labelling samples accurately, using appropriate keywords and, where possible, stratifying analyses by age subgroup. Doing so will enhance research accuracy, improve indexing and increase clinical relevance. This shift is vital for advancing autism ageing research and ensuring findings reflect the diverse experiences of autistic adults throughout later life. Lay Abstract Research on autism and ageing has increased a lot in recent years. However, many studies group everyone over the age of 50 as part of the same ‘older adult’ group. This overlooks the fact that people in midlife (ages 40–64) and those in old age (65 and older) often face very different experiences, challenges and opportunities. Recognising that midlife and old age are separate stages of life is important for understanding what autistic adults go through as they age. This letter encourages autism researchers to be more specific when describing age groups in their studies. By doing this, research on autism and ageing will be more accurate, easier to find and more useful for researchers, healthcare professionals and autistic people alike.
