The Participant REgistry for Prevention-focused Aging/dementia REsearch (PREPARE) is a database of individuals with Mild Cognitive Impairment who are interested in participating in research on aging/Alzheimer's disease and related dementias conducted at the Medical University of South Carolina (MUSC). PREPARE will connect MUSC researchers with potential participants so they can provide information about studies for which they may be eligible. PREPARE will also collect survey data from people with Mild Cognitive Impairment and their study partners to better understand the impact of this condition on daily functioning.

The goal of this study is to determine which brain health interventions are most beneficial for different people with memory concerns. Participants will complete two at-home interventions that are paired with transcutaneous auricular vagus nerve stimulation (taVNS). The first is computerized brain games, and the other is mindfulness training (MIND). Participants will be randomly assigned to complete one program first and then switch to the other program.
