Dementia Researcher Vodcast

Welcome to the seventh season of the Dementia Researcher X ISTAART PIA Relay Podcast. Across six episodes, leading early career and senior researchers hand the mic from one ISTAART PIA to the next, giving you an honest, peer-to-peer tour of where dementia research is actually heading, from wearables and biomarkers to policy and trial design, in the run-up to AAIC.
Almost everyone born with Down syndrome overproduces the amyloid precursor protein from birth, which makes it one of the clearest natural windows we have into how Alzheimer's begins. Dr Patrick Lao, Assistant Professor at Columbia and Programmes Chair of the ISTAART Down Syndrome and Alzheimer's Disease PIA, comes from a medical physics background and uses multimodal neuroimaging to map the disease across its genetic and sporadic forms. With host Lillian Morgado, he explains amyloid and tau PET, Thal phases and Braak staging, and how chronological age can stand in for disease stage in this population, with a typical symptom onset around 54. They talk about why people with Down syndrome were long left out of anti-amyloid trials and how that is now changing, and the risk and resilience research asking why some people fall off the expected timeline. Patrick also previews the PIA's AAIC PIA Day session on returning results, plus the separate DSAD/ADAD conference coming to London next year.
Takeaways
Genetic forms of Alzheimer's, including Down syndrome, let researchers study the earliest disease pathways before symptoms appear.
In Down syndrome, chronological age can approximate disease stage, with symptoms typically expected around age 54.
Imaging shows where amyloid and tau sit in the brain, the spatial detail a blood test cannot give.
People with Down syndrome were historically excluded from anti-amyloid trials; that is shifting, with a lecanemab safety extension now underway.
Not everyone follows the population timeline, and risk and resilience work asks what pushes onset earlier or later.

Welcome to the seventh season of the Dementia Researcher X ISTAART PIA Relay Podcast. Across six episodes, leading early career and senior researchers hand the mic from one ISTAART PIA to the next, giving you an honest, peer-to-peer tour of where dementia research is actually heading, from wearables and biomarkers to policy and trial design, in the run-up to AAIC.
If we cured Alzheimer's tomorrow but did no work on cost, distribution or access, we would have cured it only for the richest people in the world. That line from Lillian Morgado sits at the centre of this episode. Lillian is a research coordinator at Georgia State University and Communications Chair of the ISTAART Health Policy PIA, working mainly in qualitative research and legal epidemiology. With host Dr Vanessa Young, she talks through what qualitative work actually involves, her research on caregivers and people with dementia in the justice system, and the question that opened up next: what happens to someone with no caregiver to advocate for them. They get into why AI and blood-based biomarkers are as much policy problems as scientific ones, how regulation differs across borders, and why policy is the bridge that decides whether science reaches the people it was meant for. Lillian also runs through the Health Policy PIA's busy week at AAIC, from PIA Day to a featured research session on dementia care across countries.
Takeaways
Policy is the bridge from the lab to the patient; without it, a breakthrough only reaches the few who can already afford care.
Qualitative interviews and coding surface the right questions before the big quantitative money goes in.
Caregivers matter enormously when someone with dementia meets the justice system, which raises the question of those who have none.
AI and blood-based biomarkers carry legal and access questions, and the rules differ between, say, the US and Europe under GDPR.
You do not join a PIA because you already belong; you belong because you get involved, and you need not be an expert to contribute.

Welcome to the seventh season of the Dementia Researcher X ISTAART PIA Relay Podcast. Across six episodes, leading early career and senior researchers hand the mic from one ISTAART PIA to the next, giving you an honest, peer-to-peer tour of where dementia research is actually heading, from wearables and biomarkers to policy and trial design, in the run-up to AAIC.
Sleep might be one of the earliest windows we have into brain health, and Dr Vanessa Young thinks the way we measure it is about to change. Fresh from finishing her PhD in May, Vanessa is a postdoc at the Glenn Biggs Institute and Communications Chair of the Technology and Dementia PIA. She studies sleep and the ageing brain, where the relationship seems to run both ways: as dementia develops, sleep gets worse, and poor sleep may feed back into the disease. With host Dr Carla Abdelnour, she gets into digital biomarkers, why wearables let you capture sleep continuously at home rather than in a one-off sleep study, and the move from wearables to "nearables", bed sensors and room radar that ask nothing of the participant at all. They also cover the analysis headache that comes with years of continuous data, the equity problem when a study needs home Wi-Fi, and what the PIA has planned for its full-day AAIC preconference on AI.
Takeaways
Sleep and dementia feed each other, so sleep is worth studying as somewhere we might actually step in and help.
Wearables capture sleep night after night at home, which reaches people who live nowhere near a big sleep centre.
The field is shifting from wearables to "nearables", sensors in the mattress or radar in the room, to cut participant burden and bias.
Years of continuous data brings its own problem: telling meaningful signal apart from background noise.
If a study needs Wi-Fi to send its data, it quietly excludes people, so digital equity has to be designed in.

Most people with dementia live, and many die, at home. The person who knows them best in those final months is often not a clinician but a home care worker coming through the door several times a day, doing some of the hardest work in the dementia pathway with little training and almost no research behind them. This episode asks what good home care actually looks like, why it is so hard to deliver, and what one study is doing about it.
Host Dr Alice Carstairs is joined by the PALLDEM Homecare team from the Cicely Saunders Institute at King's College London: Dr Lesley Williamson, who co-leads the study; research assistant Annika Dhawan, who runs the engagement work; and Dr Clare Ellis-Smith, who developed the IPOS Dem outcome measure. They are joined by lived experience expert Alan Richardson, who cared for his mother for 15 years, and Tony O'Flaherty, director at Home Instead Wandsworth, Lambeth and Dulwich.
Together they cover what IPOS Dem is, why home care gets so little attention, what it really takes to get a tool used on the ground, and why recognition for this workforce is overdue.

In this episode, Professor Louise Serpell brings together Dr Niranjan Bose from the Alzheimer's Disease Data Initiative, Jonathan Hoover from the AI company Prima Mente, and Dr Kexin Huang from Stanford University and Biomni AD. They discuss the Alzheimer’s Insights AI Prize and what agentic AI could mean for the future of dementia research.
We hear about the Alzheimer’s Disease Data Initiative and AD Workbench, and their role in making research data more accessible, usable and secure. The conversation also looks at how the Alzheimer’s Insights AI Prize could help researchers make better use of that data, turning complex resources into practical tools for discovery.
Kexin introduces Biomni AD, an AI research assistant designed to help scientists develop questions, bring data together and move from ideas to results more efficiently. Jonathan introduces Parthenon and Athena, a virtual wet lab system that helps researchers model cell states, test perturbations and plan experiments.
Together, the guests consider how AI can support researchers without replacing human judgement, and why confidence in using these tools is likely to become an important skill for dementia researchers.

In this episode:
AI can support researchers by helping with data, workflows and experimental planning, but it still needs human judgement, review and validation.
AD Workbench from Alzheimer's Disease Data Initiative is helping make dementia research data more accessible, usable and secure, giving researchers better ways to work across complex datasets.
Agentic AI could help researchers move more quickly from a research question to an analysis plan, useful evidence or a possible experiment.
Biomni AD, Parthenon and Athena show how AI tools are becoming more specialised, from research assistants to virtual wet lab systems.
AI literacy is likely to become an important skill for dementia researchers, including those without coding or data science backgrounds.
