A New Non-variant CJD

Via an unnamed source: the BBC reports the discovery of a new type of sporadic CJD (Creutzfeldt-Jakob disease).

Dr Pierluigi Gambetti, director of the US National Prion Disease Pathology Surveillance Center, in Ohio, said that he believed the newly discovered type had probably "been around for years, unnoticed".
He suggested one interesting common factor was that the patients came from families with a history of dementia, suggesting a genetic cause, but did not carry the gene traditionally associated with a small number of sporadic CJD cases.
