A simple phrase like "I'm thirsty" is, for most people, a basic expression of need, a request for a glass of water. But for some elderly individuals living with cognitive impairment, the link between those words and the action of handing over a drink has already been severed, leaving only a look of confusion. According to the 2026 China Alzheimer's Disease Prevention and Treatment Blue Book, as the nation's population ages at an increasing rate, the prevalence and mortality rates of Alzheimer's disease (AD) in China are steadily climbing, making it a major illness that seriously endangers public health and hinders the sustainable development of society. Shanghai is one of the most rapidly aging cities in the country, and Putuo District has one of the highest proportions of elderly residents, with adults aged 60 and above accounting for 42.8% of its registered population. The pressure of dementia prevention and care is now radiating to the grassroots level of communities.
This strain is particularly evident in the dedicated cognitive impairment care unit at the Shanghai Longevity Home Taopu Jiucun Nursing Home in Taopu Town. Director Jiang Guilin reports that of the facility's 260 beds, 220 are currently occupied, with 32 residents living in the 46-bed cognitive impairment unit. Every resident undergoes a thorough assessment before admission and holds a professional diagnostic report, as their care needs are far more complex than those of typical elderly residents. Jiang notes that many of these residents struggle with communication, forcing caregivers to rely on close daily observation to deliver meticulous, personalized support.
This is a persistent race against the rapid decline of cognitive function. Psychologist Fu Guanglei has spent seven years providing mental health services for the elderly in Shanghai. He recalls one resident who cooperated well during training sessions, only to show a marked cognitive drop after returning from a three-month trip to Sanya. "We cannot reverse the disease; we can only try to slow the rate of decline," Fu explains. "But slowing it requires systematic, precise, and sustained training." While the progression of the illness is beyond human control, he believes volunteers can make a tangible difference in cognitive training and psychological support.
Beyond professional expertise, communities need more hands to fill the gaps. In 2022, Taopu Town established the Western Integrated Elderly Care Service Center (Taopu Town Elderly Cognitive Impairment Support Center) as a hub, connecting professional organizations and multiple volunteer teams to form a "1+X" community volunteer group that has since grown to over one hundred members. These volunteers undergo specialized dementia training and carry non-pharmacological intervention kits into nursing homes, elder care facilities, and adult day care centers to teach recognition skills, enhance communication, and assist with caregiving. The kits are designed across various cognitive domains, with each tool offering multiple levels of play, allowing users to tailor the difficulty to an individual's cognitive abilities and condition. After systematic training, volunteers can easily master the tools.
Volunteer Liu Xiaoxing's father passed away from a cerebral infarction several years ago after multiple hospitalizations. "If I had known these techniques back then, he could have been much more comfortable," Liu says, hoping his experience can help other families face fewer regrets. After participating in hands-on training, volunteer Zhang Xiaomei gained a deeper insight: "Seniors with cognitive impairment may not respond verbally right away, but interactive games often open the door to communication." Inside the nursing home, two grip balls slowly turn in an elderly resident's hands—a therapeutic exercise combining hand and brain, and part of the caregivers' daily practice of replacing commands with games.
An even longer battle unfolds in the home. Resident Nan Yan has been caring for her husband with cognitive impairment for four years. He calls for her constantly at night, leaving her with at most two to three hours of sleep. Nan herself suffers from Parkinson's disease, which is gradually worsening. The year before her husband's condition emerged, she had been hospitalized three times for heart issues and received four coronary stents. Doctors have urged her to prioritize her own health, but she faces a practical dilemma: "Someone has to do the housework. What else can I do? There's no one else." A turning point came when volunteers began visiting. Now her husband looks forward to their arrival each day. "It's like we communicate more, and he seems more cheerful," she says. The books and cards the volunteers bring have become a form of companionship Nan never imagined. However, the gap in professional intervention remains vast.
Wang Siyang, a trainer in non-pharmacological interventions for elderly cognitive decline, has calculated the math: a single home visit for cognitive training, including chatting with the senior and comforting family members, takes at least an hour and a half, with additional time needed afterward to write reports. A volunteer can serve only four families per day at most. Compounding the issue is that early symptoms of Alzheimer's are easily overlooked. "By the time the signs become impossible to hide, the disease is already severe," Wang says. Therefore, alongside intervention, public education is a crucial task—helping more people recognize the warning signals of cognitive impairment, learn how to communicate, and understand how to train. The vital value of volunteers lies in spreading this knowledge to more households.
When memory recedes, a family's life is irreversibly reshaped. In Taopu Town, efforts to build a dementia-friendly community are trying to catch these altered daily lives. The volunteers who race against time to visit homes may not be able to reverse the disease, but through repeated screenings, structured training sessions, and moments of companionship, they are carving out breathing room for families—and extending the warmth of urban governance to the finest grassroots detail.
