Who could benefit from this research
✓Could help
Ideal candidates are people living with Alzheimer's disease or related dementias and their primary caregivers who are willing to try a tablet-based program.
✕Less likely to help
People who cannot use or tolerate a tablet, have severe sensory or cognitive impairments preventing interaction, or who prefer only human-to-human engagement may not benefit.
What this research studies
You would use an iPad app where a human-looking pre-scripted avatar narrates six 22-minute audiovisual episodes designed to be stimulating and comforting. The app records your video and audio responses and uses the iPad's TrueDepth camera to capture engagement cues. LifeBio will collect feedback from people with dementia and their caregivers to refine the prototype. Brown University's geriatrics team will run a small fidelity trial with 35 patient-caregiver pairs to see how the app is used and received.
Why it matters
Potential benefit: If successful, the app could lower loneliness and challenging behaviors in people with Alzheimer's and reduce caregiver burden.
How similar studies have gone: Other digital and reminiscence therapies have shown some benefit at reducing agitation and loneliness, but autonomous avatar-based systems like this are relatively new and less proven.
