Anterior Circulation Intra- and extracranial Artery Stenosis and Cognitive Impairment

Anterior circulation intra- and extracranial artery stenosis is one of the risk factors for ischemic stroke. Recent research had proven that anterior circulation intra- and extracranial artery stenosis might cause cognitive function decline through a variety of mechanism. Its treatment methods included drug therapy, interventional therapy and surgical treatment.This paper reviewed the mechanism of cognitive impairment caused by anterior circulation intra- and extracranial artery stenosis, and its clinical manifestation and treatment, so as to provide reference for clinical work.
