Abstract: White matter lesions, leukoaraiosis on structural magnetic resonance imaging, isan important type of cerebral small-vessel disease. Plenty of studies have shown that cognitiveimpairment is closely associated with white matter lesions. Diffusion tensor imaging, whichcan detect microstructural changes in pathological processes, has become an important tool inthe assessment of cognitive impairment after stroke. In this paper the association between mildcognitive impairment after stroke and white matter lesions in recent years was reviewed.
