Has the Definition of Autism Become Too Broad to Be Useful?

A new editorial by renowned UCL professor Dame Uta Frith raises concerns that the definition of autism may have expanded so broadly that it risks confusion and potential misdiagnosis. Frith's pioneering research in the 1960s and '70s established the foundational understanding of autism that continues to inform clinical practice today. The expanded diagnostic criteria, while intended to improve identification and support for individuals on the autism spectrum, may inadvertently blur important distinctions and complicate accurate diagnosis. This concern highlights the ongoing challenge of balancing inclusive diagnostic practices with the need for precision in identifying and treating autism spectrum conditions.
