"One of America's most courageous young journalists" and the author of the #1 New York Times bestselling memoir Brain on Fire investigates the shocking mystery behind the dramatic experiment that revolutionized modern medicine (NPR). Doctors have struggled for centuries to define insanity--how do you diagnose it, how do you treat it, how do you even know what it is? In search of an answer, in the 1970s a Stanford psychologist named David Rosenhan and seven other people--sane, healthy, well-adjusted members of society--went undercover into asylums around America to test the legitimacy of psychiatry's labels.

Rosenhan's watershed study broke open the field of psychiatry, closing down institutions and changing mental health diagnosis forever.

An award-winning memoir and instant "New York Times" bestseller that goes far beyond its riveting medical mystery, "Brain on Fire" is the powerful account of one woman's struggle to recapture her identity.
When twenty-four-year-old Susannah Cahalan woke up alone in a hospital room, strapped to her bed and unable to move or speak, she had no memory of how she'd gotten there. Days earlier, she had been on the threshold of a new, adult life: at the beginning of her first serious relationship and a promising career at a major New York newspaper. Now she was labeled violent, psychotic, a flight risk. What happened?
In a swift and breathtaking narrative, Susannah tells the astonishing true story of her descent into madness, her family's inspiring faith in her, and the lifesaving diagnosis that nearly didn't happen. "A fascinating look at the disease that . . . could have cost this vibrant, vital young woman her life" ("People"), "Brain on Fire" is an unforgettable exploration of memory and identity, faith and love, and a profoundly compelling tale of survival and perseverance that is destined to become a classic.

Shortlisted for the 2020 Royal Society Insight Investment Science Book Prize Named a Best Book of 2020 by The Guardian * The Telegraph * The Times In the early 1970s, Stanford professor Dr Rosenhan conducted an experiment, sending sane patients into psychiatric wards; the result of which was a damning paper about psychiatric practises. The ripple effects of this paper helped bring the field of psychiatry to its knees, closing down institutions and changing mental health diagnosis forever. But what if that ground-breaking and now-famous experiment was itself deeply flawed? And what does that mean for our understanding of mental illness today? These are the questions Susannah Cahalan asks in her completely engrossing investigation into this staggering case, where nothing is quite as it seems.

Brain on Fire is the stunning debut from journalist and author Susannah Cahalan, recounting the real-life horror story of how a sudden and mysterious illness put her on descent into a madness for which there seemed to be no cure 'My first serious blackout marked the line between sanity and insanity. Though I would have moments of lucidity over the coming days and weeks, I would never again be the same person ...' Susannah Cahalan was a happy, clever, healthy twenty-four-year old. Then one day she woke up in hospital, with no memory of what had happened or how she had got there. Within weeks, she would be transformed into someone unrecognizable, descending into a state of acute psychosis, undergoing rages and convulsions, hallucinating that her father had murdered his wife; that she could control time with her mind. Everything she had taken for granted about her life, and who she was, was wiped out. This is Susannah's story of her terrifying descent into madness and the desperate hunt for a diagnosis, as, after dozens of tests and scans, baffled doctors concluded she should be confined in a psychiatric ward. It is also the story of how one brilliant man, Syria-born Dr Najar, finally proved - using a simple pen and paper - that Susannah's psychotic behaviour was caused by a rare autoimmune disease attacking her brain. His diagnosis of this little-known condition, thought to have been the real cause of devil-possessions through history, saved her life, and possibly the lives of many others. Cahalan takes readers inside this newly-discovered disease through the progress of her own harrowing journey, piecing it together using memories, journals, hospital videos and records. Written with passionate honesty and intelligence, Brain on Fire is a searingly personal yet universal book, which asks what happens when your identity is suddenly destroyed, and how you get it back. 'With eagle-eye precision and brutal honesty, Susannah Cahalan turns her journalistic gaze on herself as she bravely looks back on one of the most harrowing and unimaginable experiences one could ever face: the loss of mind, body and self ... a mesmerizing story', Mira Bartok, New York Times bestselling author of The Memory Palace Susannah Cahalan is a reporter on the New York Post, and the recipient of the 2010 Silurian Award of Excellence in Journalism for Feature Writing.
