Smart Homes and AI for Dementia Care: Balancing Benefits, Risks, and Real-World Access

This episode examines how artificial intelligence and smart-home technology could support people living with dementia and ease the burden on family caregivers. It traces the scope of dementia in the U.S., describes current smart-home research like Penn Nursing’s Sense for Safety project, and discusses ethical risks, data bias, privacy, and access. While AI promises proactive support—such as fall prevention and medication adherence—experts stress that technology cannot replace human care and must be studied rigorously for safety and fairness.

Introduction: The Death Trap at Home and the AI Promise

The podcast begins by framing the home as a potential danger for older adults, especially those with dementia. It surveys the rising prevalence of dementia in the United States, with projections suggesting rising diagnoses through 2060, and highlights the heavy, often unpaid caregiving burden borne by families, including time and financial costs. The episode contrasts fictional depictions of smart homes with the real-world progress toward AI-enabled safety at home, emphasizing that aging in place remains the preferred option for many seniors.

Real-World AI for Aging in Place: Sense for Safety

The discussion shifts to Penn AI Tech and Sense for Safety, a project designed to prevent falls and monitor cognitive and functional decline using privacy-preserving sensors and AI. The approach relies on depth sensors that extract silhouettes rather than identifiable video, enabling gait analysis, balance assessment, and early detection of changes. In a study of 75 older adults with mild cognitive impairment living alone in senior communities, researchers paired AI observations with quarterly clinician visits and found good concordance between AI-mediated and human assessments. The aim is to intervene proactively with tailored exercises and home modifications while reducing costs and caregiver strain. A representative from the project, George Demiris, stresses that more data improves the algorithm’s ability to predict fall risk and guide interventions.

"the more data the algorithm receives, the better it becomes at continuously calculating the individual's fall risk." - George Demiris

Ethics, Bias, and the Human Element

The episode then foregrounds ethical considerations, including data bias, privacy, and informed consent. Tiffany J. Bright discusses how training data for AI tools like chatbots for dementia patients can reflect biases in who is represented, raising concerns about accuracy and equity and the need for transparency and robust consent processes as dementia progresses. Access and equity are highlighted as critical, with the risk that early technologies may be accessible mainly to patients near major centers, leaving rural or non-English-speaking groups behind. The panel argues that successful AI for dementia must involve clinicians, social scientists, ethicists, and patients in its design and evaluation, rather than being driven solely by technologists.

Balancing Innovation with Care: Practical Paths Forward

Despite the promise, experts caution that AI cannot replace hands-on caregiving or the irreplaceable human connection in daily living tasks like eating, bathing, and dressing. The conversation emphasizes aging in place as a preferred goal for many seniors, but stresses a need for rigorous testing, ethical governance, and inclusive access to ensure these tools benefit a broad population. The panel also notes that tools should provide peace of mind while preserving dignity, and they advocate for a measured, patient-centered approach to deploying AI in home care.

"AI is great, but it's not for everything. And so I would say to a caregiver, you know, if this tool gives you peace of mind, right, and then it still honors the dignity and respect of your loved one, then I think it's worth exploring." - Tiffany J. Bright
