RESUMO
Cerebral small vessel disease is a group of diseases mainly affecting intracranial small artery and arteriole.The main characteristic changes of cerebral small vessel disease on MRI are diffuse white matter hyperintensities,lacunar infarcts,cerebral microbleeds,and enlarged perivascular spaces.These changes may be correlated with cognitive impairment.At present,many scales are available and can be used to evaluate cerebral small vessel disease caused cognitive inpairment.
