VPSPr was first reported in 2008 and further defined in 2010 (6-8) as a sporadic prion disease distinct from sCJD
. Since then, 37 cases have been reported, consistent with a prevalence rate of 1%-2% for all sporadic prion diseases (8).
Previous electroencephalography showed no relevant findings, but new analysis of a previous MRI demonstrated hyperintensity in cortex and caudate at DWI, suggestive of sCJD
Thus, he was diagnosed with probable sCJD
. His remains were cremated, and his ashes taken to Mexico by family preventing final genetic testing to be performed.
The median survival in sCJD
is 5 months, with 90% of patients dying within 1 year [1, 4, 10, 14-16].
This case highlights an unusual presentation of sCJD
characterised by a rapidly progressive impairment of consciousness and seizure activity on EEG, leading to a diagnosis of NCSE.
Over the past 2 decades, this conversion property of [PrP.sup.Sc] has been exploited to develop sensitive biofluid diagnostics for both vCJD (3) and sCJD
The possibility of foodborne and iatrogenic prion transmission, as well as the steady prevalence of sCJD
, is a potential concern for human public health, while regional expansion of CWD and occurrence of atypical animal prion diseases pose serious problems for animal health [28-31].
Aqui reportamos el caso de una mujer de 56 anos de edad, original de Puerto Rico con sospecha de CJD esporadico (sCJD
He was diagnosed as having probable sCJD
according to the "Updated clinical diagnostic criteria for sCJD
Brain homogenates from subjects affected by FFI, which contained a [PrP.sup.Sc] fragment after PK digestion ([PrP.sup.res]) of 19kDa, and from subjects with sporadic CJD (sCJD
) or a genetic CJD (gCJD) subtype linked to the E200K-129M haplotype (CJDE200K129M), which contained a [PrP.sup.res] fragment with a relative molecular mass of 21 kDa, were inoculated to syngenic mice.

The disease course of sCJD
is rapidly progressive and lasts on average 4 to 6 months.
