SUMMARY

# Vascular Contributions to Alzheimer Disease and Mixed Pathology ## Background and Rationale Cerebral small vessel disease (CSVD) represents a critical yet understudied contributor to Alzheimer's disease (AD) pathogenesis and mixed dementia phenotypes. While amyloid and tau pathologies have dominated AD research, accumulating evidence suggests vascular dysfunction may precede and accelerate neurodegeneration. This comprehensive clinical study aims to validate the mechanistic role of CSVD in AD

METHODOLOGY NOTES

Phase 1 (Months 1-6): Recruit 300 participants aged 65-85 across three cognitive groups: cognitively normal (n=100), mild cognitive impairment (n=100), and mild-moderate dementia (n=100). Screen participants using comprehensive neuropsychological batteries including MMSE, MoCA, and domain-specific tests. Phase 2 (Months 7-18): Conduct baseline multimodal neuroimaging including 3T MRI with FLAIR, T2*, and DTI sequences to quantify CSVD markers, plus amyloid and tau PET imaging using 18F-florbetapir and 18F-flortaucipir tracers. Collect cerebrospinal fluid via lumbar puncture for Aβ42, total tau, and p-tau181 quantification using ELISA. Assess vascular risk factors including blood pressure monitoring, lipid profiles, and diabetes status. Phase 3 (Months 19-42): Perform longitudinal follow-up at 6-month intervals with cognitive assessments and annual neuroimaging. Employ mixed-effects modeling to analyze relationships between CSVD burden (Fazekas scale, lacune count) and biomarker traject
