Abstract

Background: Demonstrate a theoretical and empirical justification for including potentially protective factors in Sporadic Creutzfeldt-Jakob case-controlled studies alongside the almost exclusively studied risk-enhancing factors. Methods: Synthesize existing sCJD and Alzheimer's disease (AD) research to suggest the plausibility of shared neuroprotective factors. A fixed effects longitudinal analysis of 26 countries across 10 time periods examines whether factors identified to protect against AD are associated with population-level sCJD incidence rates. Results: Increased consumption of beans and nuts, both of which are thought to protect against AD risk, is associated with lower population level sCJD incidence. Conclusion: This study suggests that factors that protect against other neurodegenerative diseases might offer protection from sCJD. The low marginal burden of including protective factors in sCJD questionnaires offers a chance to better understand sCJD at little additional cost.
