Many older adults experience changes in memory, thinking, and mood as they age. This study is exploring a promising at-home approach to support brain health using transcutaneous auricular vagus nerve stimulation (taVNS), noninvasive form of stimulation delivered through the ear. Participants use taVNS alongside computerized brain games and mindfulness exercises. By taking part, participants help our lab evaluate whether this program is practical and potentially beneficial, which helps to inform future research.
