Creutzfeldt–Jakob disease (CJD), also known as subacute spongiform encephalopathy or neurocognitive disorder due to prion disease, is a fatal neurodegenerative disease. [ 4 ] [ 1 ] Early symptoms include memory problems, behavioral changes, poor coordination, and visual disturbances. [ 4 ]
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 ]
Disease Type Treatment stage [clarification needed] CFR Notes Reference(s) Transmissible spongiform encephalopathy: Prion: No treatment and no cure [1]: 100% [2]: Includes Creutzfeldt–Jakob disease and all its variants, fatal insomnia, kuru, Gerstmann–Sträussler–Scheinker syndrome, Variably protease-sensitive prionopathy and others.
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 ...
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]).

Electroencephalogram (EEG) is used to distinguish kuru from Creutzfeldt–Jakob disease, a similar encephalopathy (any disease that affects the structure of the brain). [28] EEGs search for electrical activity in the person's brain and measure the frequency of each wave to determine if there is an issue with the brain's activity. [ 29 ]
Real-time quaking-induced conversion (RT-QuIC) is a highly sensitive assay for prion detection. [1] It is nearly 100% specific for the diagnosis of Creutzfeldt-Jakob disease . [ 2 ]
