Sporadic Creutzfeldt-Jakob disease (sCJD) occurs frequently in the relatively older population, mainly in the groups of 60-69 and 70-79 year-old. Since 2006 when China performed national CJD surveillance, 14 young probable sCJD patients below 40 year-old were identified, counting for 1.93% of all probable sCJD cases. The clinical features of young probable sCJD cases, including the onset feature, the presence of sCJD-associated signs and the clinical duration, are indistinguishable from those

CSF RT-QuIC showed positive reactive curves in 9 cases, with short lag phases. PRNP sequencing did not find any mutation. Due to low rate of brain autopsy in China, performances of other CJD-associated examinations as much as possible are extremely important for the distinguish diagnosis of young probable sCJD patients.
