Official title: LUMEN (Large Language Model for Understanding and Monitoring Elderly Neurocognition): A Clinical Feasibility Study With Nested Qualitative Evaluation for AI- Assisted Dementia Assessment
Run by Northumbria Healthcare NHS Foundation Trust · NCT07347431 · Data updated 2026-11-12
This will test LUMEN, an AI chat tool that guides caregivers to describe a loved one’s memory and thinking changes before memory clinic visits.

Is this trial a fit for you?
✓Likely a good fit
Ideal participants are adult caregivers (aged 18+) who can read basic English and accompany someone to a memory clinic, along with dementia clinicians who have at least two years of specialist dementia experience and responsibility for diagnosis.
✕Probably not a fit
People without a caregiver who can use the tool, those unable to read basic English, or patients whose needs are primarily determined by objective neurological testing rather than collateral history are unlikely to benefit directly from this project.

What this trial studies
This observational feasibility study will introduce LUMEN, a large language model–based conversational tool, into real-world memory clinic workflows to help structure caregiver collateral histories. Adult caregivers and dementia clinicians will use the prototype, complete guided conversations, and provide feedback through surveys and interviews as part of a nested qualitative evaluation. The project includes co-production workshops with community groups to address language, cultural inclusivity, and accessibility. Data collected will focus on usability, acceptability, workflow impact, and areas for improvement to inform future refinements and larger trials.
Why it matters
Potential benefit: If successful, LUMEN could produce clearer, more consistent caregiver reports that speed up clinic assessments and reduce family stress.
How similar studies have gone: Structured digital history-taking tools have shown promise in improving information quality, but applying large language models to caregiver collateral histories is relatively novel with limited prior clinical evidence.
