Summary

This study tests if a non-invasive device that stimulates the vagus nerve can improve blood flow in the brain and thinking skills in people who had a stroke 6-12 months ago. Forty participants aged 50-60 with mild cognitive issues will receive the stimulation. Researchers will measure changes in brain blood flow and scores on a thinking test.
