A prospective study for impact of the carotid artery stenting on cognitive function in patients with extracranial carotid artery stenosis. - A prospective study for impact of the carotid artery stenting on cognitive function in patients with extracranial carotid artery stenosis.

Post-CAS cognitive function varied between patients and between categories of neuropsychological tests. Although there was no significant overall improvement in working memory scores after CAS, post-CAS working memory scores changed in negative correlation with changes in FC of the DMN between the precentral/superior frontal gyrus and middle frontal gyrus. In addition, FC of the DMN between the preoperative precentral/superior frontal gyrus and medial frontal gyrus correlated positively with the post-CAS improvement in working memory.
