Dozens of people in New Brunswick have reported mysterious neurological symptoms over the past two years. People as young as 18 are experiencing full-blown dementia.

Featured in this episode: Leyland Cecco, the Guardian's Canadian correspondent; Stacie Quigley Cormier, step mother of Gabrielle Cormier who began experiencing dementia-type symptoms at the age of 20.
