Locus coeruleus (LC) neurodegeneration is associated with cognitive deterioration during the transition from normal cognition to mild cognitive impairment (MCI) and Alzheimer disease (AD). However, the extent to which LC degenerative processes differentiate cognitively normal, "resilient" subjects bearing a high AD pathological burden from those with MCI or AD remains unclear. We approached this problem by quantifying the number of LC neurons and the percentage of LC neurons bearing AT8 tau pathology, TDP-43 pathology, or a marker for DNA/RNA oxidative dama
