| Outline of Final Research Achievements |
The cognitive impairment was analyzed in 105 patients (mean age: 70.6 years) with asymptomatic carotid artery stenosis (mean rate: 81.8%). The WAIS-R2 subtests and JART did not reveal the cognitive impairment in these patients, however the discrepancy analysis between the RBANS and the WAIS-R subtests/JART clearly demonstrated the significant decline in at least one RBANS domain (immediate memory, visuospatial/construction, language, attention, delayed memory and total score) in more than 90% of the patients. Sixty of these 105 patients underwent carotid artery stenting. The postoperative RBANS scores improved in all domains in all 60 patients. The analysis of the Fazekas classification suggested that the deep white matter lesions would be the important factor to predict the postoperative improvement of the impaired cognitive function.
