White matter hyperintensities are associated with locus coeruleus atrophy and astrocytic β2‐adrenergic receptor expression

Abstract INTRODUCTION White matter hyperintensities (WMHs) are a robust marker of brain aging and dementia risk, typically attributed to vascular pathology. However, impaired astrocytic support may also contribute. The locus coeruleus (LC), which degenerates early in aging and Alzheimer's disease, provides widespread noradrenergic projections that ...
