The Age of Diagnosis by Suzanne O’Sullivan is a thought-provoking look at how modern medicine increasingly places us into diagnostic boxes.
On one hand, medical and psychological diagnoses can be profoundly validating – offering clarity, community, and language for struggles that once felt isolating. But as O’Sullivan explores, labels can also have unintended consequences. They may subtly reshape how we see ourselves, focus our attention on symptoms we might otherwise have dismissed, or even create anxiety about conditions we may never develop.
The book asks difficult but important questions:
→ What does it mean when sadness or worry become pathologised?
→ How does technology change our relationship to health when it can predict risks that may never unfold?
→ And are we paying enough attention to the social and psychological factors that shape our wellbeing – not just the biological?
