Families are increasingly turning to sensor-based devices to help manage the risks and daily challenges of dementia care. Jyoti and Bharat Patel are testing several such technologies in their home, including sensors embedded in socks, a bed fitted with monitoring equipment and motion detectors placed around rooms.
Proponents say these devices can give carers earlier warning of problems such as falls, wandering or changes in sleep patterns, potentially reducing emergency hospital visits and allowing people with dementia to remain at home longer. Sock sensors and other wearable trackers record movement and gait; smart beds can monitor sleep, breathing and restless activity; and passive motion sensors map activity in different parts of a house.
But advocates and clinicians also warn that technology is not a cure-all. Questions remain about accuracy, the risk of false alerts, data privacy and the costs of installation and ongoing monitoring. Families must weigh the potential benefits of greater safety and independence against concerns about constant surveillance and the technical support needed to keep systems running reliably.
Researchers, care providers and technology companies are testing these tools in pilot projects and studies to determine which combinations of devices are most effective and acceptable to users. For many carers, these innovations are being considered as part of a broader package of support that includes professional care, community services and practical adaptations to the home.
As the market for dementia-related technologies grows, experts urge careful evaluation, clear standards for safety and data protection, and guidance for families on integrating devices into day-to-day care without compromising dignity or autonomy. For the Patels and others trialling such systems, the hope is that appropriately used technology can ease some of the burdens of caregiving while enabling better, more timely responses to changing needs.
