Yes, many adults with autism do not realize they are on the spectrum. Research shows that a significant number of autistic adults, especially those over 40, remain undiagnosed. Studies estimate that up to 90% of middle-aged and older autistic adults in the UK have never received a formal diagnosis.
Many adults have mild or "high-functioning" autism and may have developed coping strategies that mask their challenges. They might go through life unaware of why social situations or sensory experiences are difficult. This absence of diagnosis can lead to feelings of isolation or misunderstanding.
Late diagnosis is increasingly common as awareness and diagnostic tools improve. Adults discovering their place on the spectrum often experience relief and a better understanding of themselves, enabling them to access support services and tailored therapies.
