Experts Say 89%-97% of Autistic Adults Over 60 Go Undiagnosed

Summary
89%-97% of autistic people over 60 are estimated to be undiagnosed, prompting specialists to call them a neglected generation and urge families to seek support rather than dismiss late-life struggles.
Retirement, bereavement, health decline and moves into care can strip away routines and coping mechanisms, making autism or ADHD traits more visible through distress, rigidity, isolation, fatigue or attention problems.
Doctors and psychologists say the key test is functional impact, not quirks alone, and they largely back diagnosis even in people in their 80s because it can clarify lifelong patterns and improve family understanding.
GPs are the first route to assessment, though some older adults turn to private providers; experts say any private diagnosis should involve regulated clinicians and ideally face-to-face assessments.
Support should not wait for a formal label: clearer communication, stable routines, sensory adjustments, peer support and space for hobbies can improve mental and physical health in later life.

Is it dementia, or could it be a lifetime of undiagnosed autism?
Unmasking the 90%: The Prevalence, Impact, and Solutions for Undiagnosed Autism in Older Adults
Overview
Undiagnosed autism in older adults is a widespread and hidden crisis, as many people who are now seniors were never diagnosed in childhood and still lack a formal diagnosis today. In places like Britain, up to 90% of autistic people over 50 remain undiagnosed or misdiagnosed, showing a major lack of recognition and support for this group. This underdiagnosis leads to serious problems, making it hard for older autistic adults to get the care and tailored help they need, or even to understand their own experiences as autistic individuals.
