In sporadic cases, the misfolding of the prion protein is a process that is hypothesized to occur as a result of the effects of aging on cellular machinery, explaining why the disease often appears later in life. [4] [33] An EU study determined that "87% of cases were sporadic, 8% genetic, 5% iatrogenic and less than 1% variant." [34]
