About This Book
The Age of Diagnosis (2025) argues that modern medicine and culture have become increasingly fixated on labels, expanding categories of illness in ways that can overpathologize everyday experience. It examines how the search for a name – across conditions from neurodiversity to persistent, unexplained symptoms – shapes care, community, and identity, sometimes helping and sometimes harming. It ultimately calls for a more cautious, context-aware approach that balances the relief of diagnosis with the risks of stigma, overtreatment, and misplaced certainty.
