Autistic people are more likely to experience physical and mental health difficulties across the lifespan, leading to an increased risk of premature mortality likely due to health disparities. At present, little is known about the healthcare experiences of autistic older adults. Semi-structured interviews were conducted with 19 autistic adults aged 65 years or over living in the United Kingdom. Reflexive thematic analysis produced these themes: (1) A lifetime of being misunderstood
(2) Autistic people falling between the gaps
(3) Processing autism diagnosis in later life
(4) Concerns about service pressures and scarce resources
(5) Lack of continuity of care, empathy and understanding
(6) Anxiety, alexithymia and sensory overload
and (7) Reduced social support and concerns for the future. Some of the challenges autistic older adults faced were like those experienced by younger or middle-aged autistic adults. However, they also reported additional difficulties related to ageing and lifelong experiences of social exclusion. These difficulties were made worse by increased service pressures. A comprehensive approach is needed, including enhanced staff training, personalised care, targeted support and policy changes. Services should also consult with autistic older adults so they can advocate for their care, shape policy and co-design services.Lay abstractAutistic people often face both physical and mental health challenges throughout their lives, which can lead to a higher risk of premature death due to health inequalities. However, we know very little about the healthcare experiences of autistic older adults. In this study, we talked with 19 autistic adults aged 65 years or above living in the United Kingdom. We found these main themes: (1) A lifetime of being misunderstood
(2) Autistic people falling between the gaps
(3) Processing autism diagnosis in later life
(4) Concerns about service pressures and scarce resources
(5) Lack of continuity of care, empathy and understanding
(6) Anxiety, alexithymia and sensory overload
and (7) Reduced social support and concerns for the future. Themes show that autistic older adults face unique healthcare access challenges because services don't consider their lifelong experiences of social exclusion. Participants also worried about age-related decline coupled with reduced social support, which makes it harder for them to get support. To address these challenges, healthcare services should provide more targeted support, make policies and funding consistent, and improve healthcare provision by providing staff training. Importantly, they must also speak with autistic older adults so they can advocate for their current and future care.
