TL;DR
Many older adults remain undiagnosed with autism or ADHD, which can impact their well-being. Experts recommend considering diagnosis if traits cause significant issues, but approaching this topic requires sensitivity. The development highlights the importance of awareness for adult children caring for aging parents.
Recent research indicates that a significant majority of adults over 60 with autism or ADHD remain undiagnosed, prompting experts to urge awareness among adult children caring for aging parents. Recognizing traits that impact daily life can lead to better support and understanding, even if diagnosis occurs late in life.
Studies estimate that 89-97% of autistic individuals over age 60 are undiagnosed, leading to what experts call a “neglected generation”. Age-related changes, such as retirement and health issues, can make neurodivergent traits more apparent or difficult to manage, increasing the importance of awareness and potential diagnosis.
Experts like Dr Louise Rutter and Dr Neil Drew emphasize that traits such as difficulty with social situations, routines, or sensory sensitivities may become more visible in later life. Recognizing these signs can help families seek support and understanding for their older relatives.
While diagnosis is beneficial at any age, experts encourage considering it for older adults if traits cause significant distress or functional issues. Approaching the topic with sensitivity is recommended, as many may have masked or misunderstood their experiences for decades.
Why Recognizing Neurodivergence in Older Adults Matters
Understanding whether an aging parent is neurodivergent can significantly improve their quality of life by providing tailored support and reducing feelings of isolation. It also helps adult children better understand their parents’ behaviors and needs, fostering stronger relationships.
Late diagnosis can open pathways to resources, community support, and a sense of validation. It challenges the misconception that neurodivergence is only a childhood issue and highlights the importance of lifelong awareness and acceptance.

Rise in Awareness and Underdiagnosis in Older Adults
Recent years have seen increased recognition of neurodiversity, especially in children and middle-aged women. However, older adults, particularly those over 60, remain largely undiagnosed, with estimates suggesting up to 97% are not identified. This gap is partly due to historical lack of awareness and diagnostic criteria that focused on children.
Studies, such as one by the British Psychological Society, highlight that aging can reveal or exacerbate neurodivergent traits, making late-life diagnosis more relevant. Experts warn that the decline in routine and social engagement during retirement can unmask or worsen these traits.
Efforts are now underway to improve screening and support for this underserved group, recognizing that late diagnosis can be transformative for individuals and their families.
“Many autistic adults over 60 remain undiagnosed, which means they are often overlooked in terms of support and understanding.”

It is not yet clear how many older adults would benefit from diagnosis or how best to implement screening programs. There is also limited data on the outcomes of late diagnosis, including psychological impacts and access to support services. Additionally, some individuals may resist diagnosis due to stigma or personal beliefs.
