'The answer cannot be nothing': The battle over Canada's mystery brain disease

Five hundred people in a small Canadian province were diagnosed with a mystery brain disease. What would it mean for the patients if the disease was never real?

In early 2019, hospital officials in New Brunswick observed cases of Creutzfeldt-Jakob Disease (CJD), a lethal and potentially contagious brain condition. Dr Alier Marrero, a neurologist, noted a rising number of patients displaying symptoms similar to CJD, leading him to suspect an unknown neurological condition.

Over five years, the cluster grew to 500 cases. However, a recent study concluded that these patients might suffer from known medical or psychological conditions, labeling the phenomenon a "house of cards." Patients continue to dispute this diagnosis, citing environmental toxins as a potential causative factor.

Amidst the outcry, Dr Marrero garnered both respect and criticism; his dedication to patient care conflicting with accusations of misdiagnosis from mainstream medical experts. A looming provincial report may finally address the concerns of the thousands affected.
