White matter hyperintensity, parent artery steno‐occlusion, and neurological deterioration in anterior circulation single subcortical infarction patients

The evidence for the association between white matter hyperintensity (WMH) severity and neurological deterioration (ND) in patients with single subcortical infarction (SSI) remains unclear and whether the association between them is modified by anterior circulation parent artery steno-occlusion (PAS) is unknown. Herein, we aimed to prospectively investigate the internal relevance.
