Recognizing and Supporting Older Autistic Adults: Addressing Gaps in Healthcare and Diagnosis

Understanding the Undiagnosed Majority

Research from King's College London (2025) suggests that 89-97% of middle-aged and older autistic adults in the UK may lack formal diagnoses. This gap in recognition can limit access to tailored healthcare accommodations and support services, as highlighted in a neurodiversity-affirmative review by Sage Journals.

Health Disparities and Systemic Barriers

Studies, including one in Scientific Reports, report higher rates of chronic conditions such as cardiovascular disease and diabetes among older autistic adults. These disparities may stem from lifelong barriers to preventive care and healthcare accommodations. Preliminary data on life expectancy differences, as noted in Being Patient's 2026 review, suggest varied outcomes, with significant gaps for those with additional support needs, though more research is needed.

These disparities may stem from lifelong barriers to preventive care and healthcare accommodations.

Mental health challenges, including higher rates of depression and anxiety, are also noted in a 2026 Nature study, with social isolation and lack of accessible community spaces identified as contributing factors.

Pathways to Improvement

An NIH review calls for healthcare reforms, including training for providers on autism in older adults and developing age-appropriate support services. The University of Utah Health is leading a significant study on aging in autistic adults, aiming to fill research gaps.

Practical Steps for Support

• Seeking Diagnosis: Older adults or their families can consult healthcare providers about autism assessments tailored to adults.
• Healthcare Accommodations: Requesting sensory-friendly environments or clear communication from providers can improve healthcare experiences.
• Community Connections: Engaging with autistic-led organizations or support groups can reduce isolation, as suggested by Autism Spectrum News.
