BID LTM Digital Intervention in Aging
- Conditions
- Long-Term MemoryInhibitory Control
- Registration Number
- NCT06916221
- Lead Sponsor
- University of California, San Francisco
- Brief Summary
Healthy aging is typically accompanied by diminished capability for learning and retrieval of high-fidelity long-term memory (LTM). The decline in these faculties is accelerated and becomes significant deficits in LTM and cognitive control functions at the level or a diagnosis of Mild Cognitive Impairment (MCI). Training with the navigation game, relative to training with control games, is expected to improve LTM performance for older adult participants.
Researchers will compare two different digital interventions to assess whether they may be helpful in improving cognitive function.
Participants will conduct study activities remotely (e.g., at-home):
1. Baseline Assessment. Complete a series of cognitive assessments and surveys.
2. Intervention. Engage in a digital intervention for up to 8 weeks.
3. Post Intervention Assessment. Complete the same cognitive assessments and surveys as the Baseline Assessment.
4. Follow-Up Assessment. Six months after the intervention ends, participants will complete the same cognitive assessments and surveys as the Baseline Assessment.
- Detailed Description
Older adult participants consent and enroll in the LTM Digital Intervention, which is a randomized control trial (RCT) administered on the Neuroscape Nexus web-based research platform. Enrolled participants are randomly assigned to either of two arms that will play memory-based games.
Participants are provided by the study team with an Apple iPad 10th Generation (2024) at their home address, which will enable them to complete all study tasks at home via Nexus. All required applications will be pre-loaded on the device.
Participants will receive notifications and reminders to complete study tasks by email, through in-app reminders, or SMS. They can view their task list and progress in their personal dashboard in Nexus.
Study procedures include a series of surveys and brief tests of memory and attention as Baseline Tests, which make take up to 120 minutes and can be completed across more than one session.
Participants will engage with their assigned training application to complete 45 minutes of training, several days a week for up to 8 weeks for a total of 1000 minutes of training. Participants will be randomly assigned to one of two intervention apps, which encourage long-term memory.
Once their assigned training regimen is complete, participants will again fulfill a series of surveys and brief tests of memory and attention as Post-Training Tests, which make take up to 120 minutes and can be completed across more than one session.
Six months after completion of all Post-Training Tests, participants will be fulfill a third series of surveys and brief tests of memory and attention as Follow-Up Tests, which make take up to 120 minutes and can be completed across more than one session.
