Objective To study the incidence rate of depression state in asymptomatic cerebral infarction (ACI) and the correlation between them.

Results KNT could alleviate volume of cerebral infarct caused by focal cerebral ischemia in a dose- dependent manner and improve neurological symptoms.

IV fibrinolysis can be considered in patients with rapidly improving symptoms, mild stroke deficits, major surgery within the past 3 months, and recent myocardial infarction.
