SUMMARY

# Traumatic Brain Injury and Alzheimer's Disease Relationship ## Background and Rationale This comprehensive validation study investigates the causal relationship between traumatic brain injury and Alzheimer's disease development, addressing a critical gap in understanding neurodegenerative disease mechanisms. While epidemiological evidence suggests TBI increases AD risk, the underlying biological pathways remain poorly characterized. This research combines large-scale retrospective analysis wit

METHODOLOGY NOTES

**Phase 1: Retrospective Cohort Assembly and Data Mining (Months 1-6)** Analyze electronic health records from 3 major healthcare systems to identify 5,000 individuals with documented moderate-severe TBI (Glasgow Coma Scale ≤12) and 15,000 matched controls. Extract TBI characteristics (mechanism, severity, age at injury, rehabilitation records) and follow for minimum 10 years. Identify subsequent AD/dementia diagnoses using ICD codes, neuropsychological testing, and neuroimaging reports. Collect genetic data where available (APOE status) and medication histories. Apply exclusion criteria: pre-existing dementia, severe psychiatric illness, or other neurodegenerative diseases. **Phase 2: Prospective Biomarker Study (Months 7-18)** Recruit 300 participants: 100 with remote TBI (5-15 years post-injury), 100 with recent TBI (1-2 years), and 100 controls. Collect CSF via lumbar puncture for AD biomarkers (Aβ42, tau, p-tau181) using Lumipulse assays. Perform plasma analysis for emerging bi
