Summary
Carotid artery stenting (CAS) significantly improves cognitive functions, including psychomotor speed, memory, and executive function, in patients with carotid atherosclerosis over a 12-month period.
Area of Science:
- Neurology
- Vascular Surgery
- Cognitive Neuroscience
Background:
- Carotid artery revascularization reduces stroke risk and enhances cognitive function.
- Carotid artery stenting (CAS) is a common procedure for treating carotid atherosclerosis.
- The impact of CAS on specific cognitive domains requires further investigation.
Purpose of the Study:
- To evaluate cognitive function changes in patients following CAS.
- To test the hypothesis that CAS improves psychomotor speed, visuospatial episodic memory, executive function, and verbal fluency.
- To track these cognitive changes over a 12-month follow-up period.
Main Methods:
- A cohort of 47 patients undergoing CAS was assessed.
- Cognitive functions were evaluated using a battery of psychological tests (DS, ROCF, WCST, LVF) pre-procedure and at 12 months post-procedure.
- Sociodemographic and clinical data were collected via questionnaire.
Main Results:
- Significant improvements were observed in psychomotor speed, visuospatial episodic memory, and executive function one year after CAS.
- No significant changes or decline were noted in verbal fluency.
- Cognitive benefits were observed in patients with carotid atherosclerosis treated with CAS.
Conclusions:
- Carotid artery stenting demonstrates a positive effect on cognitive functioning in patients with carotid atherosclerosis.
- The procedure enhances both basic and complex cognitive abilities.
- CAS is a viable option for improving cognitive outcomes in this patient population.
