Autism in Adults

Many adults describe a journey that includes:
- Wondering - "Is there something different about me?"
- Researching - Learning about autism and recognizing traits

A Note on the Diagnostic Debate
Autism diagnosis itself is a subject of active debate. In 2026, pioneering researcher Uta Frith questioned whether the spectrum has become so broad that it is leading to misdiagnosis — noting that difficulties may sometimes stem from anxiety, depression, or trauma rather than autism. If you're exploring a diagnosis, it helps to understand both sides of this debate:
