Abstract: Cerebral infarction affects both cerebral autoregulation and cerebral perfusion. This review articlesummarizes the published evidence of cerebral autoregulation impairment and cerebral blood flowalteration after cerebral infarction, including cerebrovascular small vessel disease leading to animpairment of vasoreactivity, blood flow velocities and cerebral blood flow associated positivelywith systemic blood pressure, perfusion declined on the infarcted side and lower blood pressureresulting in hypoperfusion in distal area of the narrowing main cerebral artery. The question shouldbe thought by physicians about what is the 'best blood pressure range' in patients with cerebralinfarction and it will be benefit for optimal recovery.

Key words: Brain infarction; Blood pressure; Perfusion
