“It’s not always easy to enter the emotional state of those with dementia,” says Poh Yun Ru, a young designer at the National University of Singapore’s Design Incubation Centre. And she would know. Poh’s own grandmother suffers from dementia, a first-hand experience that helped inspire Poh’s award-winning cognitive therapy tool, Rewind.
Dementia encompasses a set of cognitive disorders that progressively impair memory, thinking, and—of particular importance to Poh—the ability to perform simple, everyday activities. It is often characterized by problems with problem solving, as well as profound changes in patients’ behavior and emotions. According to to data of the World Health Organization (WHO), more than 55 million people worldwide suffer from it. That number is only expected to increase as living standards rise worldwide and people live longer – making age-related conditions such as dementia more common and more prevalent. The result is a significant public health challenge, with dementia’s impact extending beyond individuals and affecting their families, who must grapple with the emotional and practical challenges of supporting loved ones.
Enter Rewind, which uses visual aids, motion tracking tools and sensory cues to stimulate memory so dementia patients can relearn how to carry out day-to-day tasks such as making tea, watering plants, flipping pancakes and walking their dogs. Patients use the motion tracking tool while watching video of the action or gesture, which creates “multi-sensory stimulation” and prompts “meaningful memories” that help dementia sufferers re-engage with their environments and regain autonomy in their routines.
Recognizing that the mass market would be unlikely to produce therapy tools for a relatively niche population, Yun Ru developed Rewind with help from doctors, healthcare workers and dementia patients themselves.
“It’s really encouraging to see how Rewind not only promotes engagement among the elderly, but also stimulates them to connect their memories with the therapy activities,” she tells Quartz. “I really enjoy learning and seeing the world from new perspectives and creating something that becomes relevant and meaningful to the community. Knowing that the design has impacted the lives of even a small group of people is truly rewarding and keeps me going.”
