Fatal insomnia is an extremely rare neurodegenerative prion disease that results in trouble sleeping as its hallmark symptom. [2] The majority of cases are familial (fatal familial insomnia [FFI]), stemming from a mutation in the PRNP gene, with the remainder of cases occurring sporadically (sporadic fatal insomnia [sFI]).
The Creutzfeldt-Jakob Disease Surveillance System (CJDSS) is a unit of the Public Health Agency of Canada. It studies the various variants of Creutzfeldt-Jakob Disease , and at least as of 2017, assisted "with DNA sequencing , autopsy and case confirmation". [ 1 ]

In 2019, through routine case management between the New Brunswick Regional Health Authorities and the federal Ottawa-based Creutzfeldt-Jakob Disease Surveillance System (CJDSS), CJDSS had observed that a significant number of referrals from New Brunswick had "some common symptoms and similar potential diagnostic profiles".

vCJD is a separate condition from classic Creutzfeldt–Jakob disease (though both are caused by PrP prions). [9] Both classic and variant CJD are subtypes of Creutzfeldt–Jakob disease. There are three main categories of CJD disease: sporadic CJD, hereditary CJD, and acquired CJD, with variant CJD being in the acquired group along with ...

Prion diseases comprise Creutzfeldt–Jakob disease (CJD), Gerstmann–Sträussler–Scheinker syndrome, fatal familial insomnia and related disorders. [1] A specialist prion disease clinic was established by Professor John Collinge at St Mary's Hospital, London, in 1997. [2]
