The Elusive Body

Patients, Doctors, and the Diagnosis Crisis

De: Alexandra Sifferlin

A compelling, necessary, and timely investigation into the diagnosis crisis in the American healthcare system, from the patients living with undiagnosed illnesses, to the doctors searching for answers, and what their quests reveal about our flawed medical system

An estimated tens of millions of Americans live with conditions that elude diagnosis, often navigating a healthcare system that fails to recognize or effectively address their suffering. Journalist Alexandra Sifferlin has spent years investigating the diagnosis crisis in America—what it means to live without a diagnosis and how both medical and patient communities are working to improve the diagnostic process. The National Institute of Health’s Undiagnosed Diseases Network, a series of clinics of last resort where physicians work tirelessly to solve some of medicine’s most confounding cases, is at the forefront of change, showing what’s possible when healthcare providers and scientists are freed from the bureaucracy of a system beholden to insurance companies, and encouraged to work together with the aim of solving some of medicine’s most perplexing mysteries.

A correct diagnosis is more than a label; it’s a lifeline that opens doors to treatment options, financial support, and an understanding community. Weaving the profound, maddening, and uplifting stories of patients seeking answers to unexplainable symptoms, the doctors trying to help them, and the latest research on diagnosis, The Elusive Body illuminates the diagnostic journey, revealing why diagnoses matter and how they have the power to transform lives, the medical system, and even society, one case at a time.
