Abstract:

Cerebral small vessel disease (CSVD) is the most common vascular cause of cognitive impairment in the elderly. The lesion-symptom mapping studies found that the damage of strategically located white matter microstructure may be the potential pathogenesis of CSVD-related cognitive impairment, namely cortical-cortical or cortical-subcortical disconnection syndrome. Diffusion tensor imaging (DTI) provides a non-invasive fiber tracking method for the study of white matter microstructure damage. Therefore, this article reviews the study of disconnection syndrome in CSVD-related cognitive impairment and the correlation between fiber microstructure damage and different cognitive domain dysfunction in DTI studies.

Key words: Cerebral small vessel disease, Cognitive impairment, Disconnection syndrome, Microstructure damage, Diffusion tensor imaging
