Synopsis

From a neurologist and the award-winning author of The Sleeping Beauties, a meticulous and compassionate exploration of how our culture of medical diagnosis can harm, rather than help, patients.

We live in an age of diagnosis. Conditions like ADHD and autism are on the rapid rise, while new categories like long Covid are being created. Medical terms are increasingly used to describe ordinary human experiences, and the advance of sophisticated genetic sequencing techniques means that even the healthiest of us may soon be screened for potential abnormalities. More people are labeled "sick" than ever before—but are these diagnoses improving their lives?

With scientific authority and compassionate storytelling, neurologist Suzanne O'Sullivan argues that our obsession with diagnosis is harming more than helping. It is natural when we are suffering to want a clear label, understanding, and, of course, treatment. But our current approach to diagnosis too often pathologizes difference, increases our anxiety, and changes our experience of our bodies for the worse.

Through the moving stories of real people, O'Sullivan compares the impact of a medical label to the pain of not knowing. She explains the way the boundaries of a diagnosis can blur over time. Most importantly, she calls for us to find new and better vocabularies for suffering and to find ways to support people without medicalizing them.

Goodreads review by Sadhbh on March 09, 2025

4.5 rounded up. These are such contentious topics but what I enjoyed was how empathetically this was written. The purpose is not to deny that people are suffering but to question whether diagnoses, especially when the act of diagnosis is so subjective, will really help people. The question of how yo......more

Goodreads review by Debby on March 24, 2025

I listened to the abridged version of this on BBC Sounds. It was excellent. The author explores topics such the diagnosis for Huntingdon’s Disease, Autism, Cancer and Long Covid. Each chapter is done in a very procedural way but which may not be popular with all readers. She is a courageous author a......more

Goodreads review by SociologistInMe on March 20, 2025

The book covers important topics - what is overdiagnosis; is a diagnosis always a good thing; are we pathologizing anxiety; what are the dangers of overdiagnosis - particularly, changes in behaviours because of a diagnosis that then worsens or at least exacerbate the condition. The book raises some......more

Goodreads review by Pedro on March 24, 2025

“Diagnosis is an art and a science, but, surprising as it may sound to some, the art still takes precedence.” It could be stated, I suppose, that this book makes a compelling argument that “the truth is overrated”... not an easy stance at all. And extremely problematic, obviously. Writing this book......more


Quotes

“With grace, elegance, and compassion, The Age of Diagnosis slices through the confusion and the contradictions that have tied me in knots—both as a parent and as a clinician. Dr. O’Sullivan’s previous books made a big impression on me and influenced my clinical practice. This will do the same and more.” —Chris van Tulleken, author of Ultra-Processed People

“O’Sullivan explodes conventional wisdom about medical diagnoses. With clarity of prose and reasoning, The Age of Diagnosis should make all of us think about whether we are more or less healthy when we receive a diagnostic label.” —Elizabeth Loftus, distinguished professor, University of California, Irvine

“A brave and deeply empathetic book with a very important message.” —Henry Marsh, author of Do No Harm

“A book of great wisdom as well as compassion—the result of decades working along the frontiers of brain, mind, and body. Modern medicine is powerful; with care, and with stories from her clinic, Dr. O’Sullivan shows just how harmful it can be too.” Gavin Francis, author of Adventures in Human Being
