Fan Favorite | Sudden Insanity

Following the epic crossover between MrBallen’s Medical Mysteries and Redacted: Declassified Mysteries, hosted by Luke Lamana, we’re revisiting some of our favorite episodes where the line between medical mystery and dark conspiracy becomes blurred. When an elderly man in New Brunswick, Canada, dies from what seems to be rapid-onset dementia, his doctor believes he had a rare condition called Creutzfeldt-Jakob Disease. But then, dozens of people around the area start experiencing the same awful symptoms, making the doctor fear he’s dealing with something entirely new… and completely terrifying.
