Brain disorder with symptoms including hallucinations and memory loss has Canadian doctors baffled

Prion Diseases

A “cluster” of patients experiencing hallucinations and memory loss has doctors in northeast Canada concerned that they’re seeing a new kind of brain disease.

The Guardian reports that for over the course of more than a year, public health officials in New Brunswick have encountered 43 cases of suspected neurological disorders with no known cause. Officials have told the public not to panic over the smattering of cases, though politicians are pressuring the medical community for answers.

A leaked memo last week from province officials reportedly asked medical workers to report symptoms like those associated with the rare and deadly Creutzfeldt-Jakob disease, which is thought to be a prion disease. Johns Hopkins University defines a prion as “a type of protein that can trigger normal proteins in the brain to fold abnormally.”

Such diseases are said to affect humans and animals and can spread to people through infected meat products.

Neurologist Dr. Alier Marrero, who is leading the New Brunswick investigation, told The Guardian there is no reason so far to believe what his team is seeing now is a prion disease.

While researchers are exploring whether or not they’re looking at a neurological mystery, Marrero says some symptoms listed by patients early on were consistent with anxiety and depression. But further observation reportedly revealed cognitive decline, drooling and teeth chattering, with some patients experiencing hallucinatory sensations akin to bugs crawling on skin.

University of Alberta researcher Valerie Sim told The Guardian there isn’t yet enough information for medical experts to know what these recent cases indicate.
