Inclusion criteria

Inclusion criteria: (1) Subjects aged 40-80; (2) Participants with cognitive impairment in memory or other cognitive domains for at least 3 months are diagnosed with mild cognitive impairment (cognitive impairment in one or more cognitive domains is insufficient to affect the independence of life) according to the Chinese Diagnosis and Treatment Guidelines for Cognitive Dysfunction Related to Cerebrovascular Diseases (2019); (3) Montreal Cognitive Assessment (MOCA) score<26 (does not meet the dementia diagnostic criteria of the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders); (4) Head computed tomography or magnetic resonance imaging shows recent subcortical infarctions, lacunar hyperintensities (WMHs), increased perivascular spaces, and microbleeds. According to the Chinese Guidelines for the Diagnosis and Treatment of Cognitive Dysfunction Related to Cerebrovascular Diseases (2019) and the Chinese Consensus on the Diagnosis and Treatment of Cerebrovascular Diseases (2015), there are 2 or more cases of extrabrainstem lacunar infarctions, with a Fazekas score of = 2 and a number of microbleeds = 3; (5) Participants who signed informed consent forms to participate in the trial.
