Description

Summary

This study tests the feasibility, acceptability, and efficacy of a multimodal intervention (walking, social engagement, and reminiscence), including the use of wearable digital biomarkers, for cognitively healthy and mildly cognitively impaired African Americans aged 65 and older.

Official Title

Efficacy of a Technology-Based Multimodal Brain Health Intervention for Older African Americans: The SHARP Study

Details

Cognitively healthy and mildly cognitively impaired participants engage in 16 weeks of triadic neighborhood walking using a group tablet device to access pre-programmed 1-mile routes. GPS (Global Positioning System)-triggered historical images of local Black culture and history along the route prompt conversational reminiscence about Portland, Oregon's historically Black neighborhoods. Digital biomarker technology (a continuously worn actigraph watch and an unobtrusive under-the-mattress sleep sensor) and weekly online surveys via a study Chromebook assess feasibility, acceptability, efficacy, and health outcomes. Intermittent discussions and check-ins with participants, and observational sessions will be used to elicit participant feedback.

Eligibility

You can join if…

Open to people ages 65-110

  1. Self-identified African American,
  2. Age > 65 years old
  3. Reside or resided for >10 years in Portland's historically Black neighborhoods (to be familiar with Memory Markers about this area),
  4. Able to ambulate independently.
  5. Meeting Cognition Criteria
  6. Participants with MCI (Mild Cognitive Impairment) will meet criteria consistent with the criteria outlined by the NIA-Alzheimer's Association workgroup
  7. Participants without cognitive impairment will have a Montreal Cognitive Assessment (MoCA) score > 24 (and not meet MCI criteria). Participants' cognitive function should allow them to get to and from walk locations independently or with minimal assistance.
  8. Cognitive function allows independent (or minimally assisted) travel to and from walk locations
  9. In-home reliable broadband internet (for weekly online surveys).
  10. Ability to read, speak, and understand English

You CAN'T join if...

  1. Self-reported or clinically diagnosed dementia
  2. Significant disease of the central nervous system
  3. Severely depressed (CES-D score > 16), significantly symptomatic psychiatric disorder
  4. Advanced cardiovascular disease that would make walking difficult, including history of congestive heart failure
  5. Unstable insulin-dependent diabetes mellitus, received diagnosis Type 1 Diabetes, started insulin within past 3 months, hospitalized for hypoglycemia within past 6 months.
