In the Canadian province of New Brunswick, approximately five hundred people were diagnosed with a mysterious brain disorder that resembled prion disease[1]. Provincial Premier Susan Holt is asking the Public Health Agency of Canada to help investigate this mysterious brain disease[1]. A 2025 study offered possible explanations for the causes of the disease[1]. However, some patients rejected these findings[1]. The article also mentions the Alzheimer's clinical trial and the related lawsuit[1]. Another topic is brains in space in the context of scientific research[1].
