SUMMARY

# Pre-Symptomatic Detection and Intervention Timing in Genetic Prion Disease ## Background and Rationale This longitudinal validation study addresses the critical challenge of early detection and therapeutic intervention in genetic prion diseases, including familial Creutzfeldt-Jakob disease (CJD), Gerstmann-Straussler-Scheinker syndrome (GSS), and fatal familial insomnia (FFI). Carriers of pathogenic PRNP mutations face nearly inevitable disease development, but the extended asymptomatic period

METHODOLOGY NOTES

Phase 1 (Months 1-6): Recruit 300 asymptomatic PRNP mutation carriers, 150 healthy controls, and 100 symptomatic prion disease patients through genetic counseling centers and neurology clinics. Obtain informed consent and establish baseline measurements including comprehensive neurological examination, cognitive testing battery (MMSE, MoCA, detailed neuropsychological assessment), and genetic confirmation. Phase 2 (Months 6-12): Implement standardized biomarker collection protocols. Obtain lumbar puncture for CSF analysis (PrPSc by RT-QuIC, NfL, tau, p-tau181, inflammatory cytokines) and blood samples for plasma biomarkers using ultrasensitive immunoassays. Perform multimodal neuroimaging including 3T MRI (T1-weighted, FLAIR, DTI), functional MRI during cognitive tasks, and PET imaging with [11C]PIB and experimental prion tracers. Phase 3 (Years 1-10): Conduct longitudinal follow-up with biomarker collection every 6 months, neuroimaging annually, and continuous digital monitoring via s
