Carotid artery stenting (CAS) may improve cognitive and memory functions. Neuropsychological tests showed enhanced performance in some areas post-procedure, suggesting potential benefits for brain perfusion.

Area of Science:

  • Neurology
  • Cardiovascular Medicine
  • Cognitive Science

Background:

  • Carotid artery stenting (CAS) is a procedure to open blocked carotid arteries.
  • Potential effects of CAS on cognitive function require further investigation.

Purpose of the Study:

  • To evaluate changes in cognitive performance following CAS.
  • To assess the impact of CAS on memory and executive functions.

Main Methods:

  • Ten patients underwent neuropsychological testing before and after CAS.
  • Tests included the Mini Mental State Examination (MMSE) and CERAD subtests.
  • A proximal protection device was used to minimize thromboembolic events.

Main Results:

  • No patients exhibited depression or dementia.

  • Improved performance was noted in the Number Connection Test (NCT) and delayed recall.
  • No significant changes were observed in other cognitive tests like verbal fluency or word list memory.

    • Conclusions:

    • CAS may lead to improvements in cognitive and memory performance.
    • Enhanced brain perfusion could be a contributing factor.
    • Further research with extended follow-up and advanced imaging is recommended.
