Alzheimer's &Dementia, Volume 22, Issue 6, June 2026.Abstract INTRODUCTION Locus coeruleus (LC) structural integrity declines early in sporadic and autosomal dominant Alzheimer's disease (AD). We examined LC–entorhinal cortex (LC‐EC) tract integrity and its association with amyloid and tau pathology and memory in autosomal dominant AD (ADAD).
