This, Sullivan's first book, was published by Chatto & Windus in 2015,^[21] to positive reviews.^[1][5] It has been recognised by multiple nominations and awards.^[3][4][9]

It's All in Your Head discusses issues surrounding psychosomatic illness, with particular attention given to its neurological manifestations.^{[citation needed]} Specifically, it explores the mind-body connection through stories of O’Sullivan's patients, looking compassionately at serious medical problems that arise through psychological mechanisms.^{[citation needed]} As well, O'Sullivan considers the history of the hysteria from ancient to modern times, discusses diagnosis, causes, mechanisms and treatment of neurological psychosomatic disorders in the modern era.^{[citation needed]} Among the characters it presents are:

• Pauline, a woman experiencing since her mid-teens multiple unexplained and progressive medical issues, with symptoms including seizures and paralysis;^{[citation needed]}
• Matthew, a man convinced he has multiple sclerosis, who struggles to accept alternate explanations for his leg paralysis;^{[citation needed]} and
• Camilla, a lawyer, who experiences seizures, and cannot face their cause.^{[citation needed]}

This, O'Sullivan's second book,

Brainstorm published in 2018 by Chatto & Windus.^[22]is an account of how the study of epilepsy changed scientists’ understanding of the human brain.^{[citation needed]} It explores modern views and treatments for epilepsy, and looks at what each teaches about how the brain functions.^{[citation needed]} Among the characters Brainstorm presents are:

• Donal, who hallucinates cartoon dwarves;^{[citation needed]}
• Maya, who faces possible radical surgery to address her epilepsy;^{[citation needed]}
• Sharon, who experiences seizures who cause was other than diagnosed;^{[citation needed]}

This, O'Sullivan's third book, was published in April 2021 by Picador in England,^[23] and by Pantheon in the United States,^{[citation needed]} and was lauded by The Royal Society and other organisations.^[15][16][17]

Brandy Schillace, editor-in-chief of the journal Medical Humanities at the time her review, writes in The Wall Street Journal that O'Sullivan "uncovers... complex mechanisms while painting a picture of psychosomatic suffering that removes its associated stigma, and she asks us to think about illness in new ways." She concludes,

The Sleeping Beauties offers a brilliant, nuanced and thoughtful look at the lived experience of illness while asking important questions about the relationship between body and mind. Dr. O’Sullivan’s rich prose weaves a tapestry as hauntingly beautiful as it is scientifically valid.^[24]

In this book, O’Sullivan travels to visit communities globally that are said to be affected by mass hysteria and culture bound syndromes—ways that specific cultures express distress, troubled thoughts, etc.^{[citation needed]} Among the characters Brainstorm presents are:

• schoolgirls in Colombia presenting with seizures, as an apparent contagious outbreak;^{[citation needed]}
• Kazakhstani townspeople presenting with apparent sleeping sickness, again apparently contagious;^{[citation needed]}
• the victims of sonic weapon attacks;^{[clarification needed][where?][citation needed]}
• indigenous Nicaraguans presenting with 'crazy sickness';^{[citation needed]} and
• a New York high school presenting with a Tourette's-like syndrome that is spreading.^{[citation needed]}

This, O'Sullivan's fourth book, was published in March 2025 by Thesis-Penguin Random House in England,^[25] to positive early reviews.^{[6][citation needed]}
