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.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]

The Sleeping Beauties: And Other Stories of Mystery Illness (2021)

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

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.

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]
