Correspondence between white matter hyperintensities and regional grey matter volumes in Alzheimer's disease.

Objective: White matter hyperintensities (WMH) are the most common neuroimaging manifestation of cerebral small vessel disease, and is frequently observed in Alzheimer's disease (AD). This study aimed to investigate the relationship between WMH and cognition and to verify the mediation of grey matter atrophy in this relationship.

Methods: The diffusion tensor imaging (DTI) technique analyses white matter fiber tract to assess white matter integrity.
