Pets May Slow Dementia Progress in Older Adults Living Alone, Study Reveals
Scientific research has shed light on a remarkable correlation: owning a pet may help slow the progression of dementia in individuals over 50 living alone.
Pets provide companionship, reducing feelings of loneliness in older adults.
Reducing Loneliness and Dementia Risk with Pets
Led by researchers at Sun Yat-sen University in China, the recent study, published in the Journal of the American Medical Association (JAMA), found that pet ownership can significantly slow the rate of cognitive decline in older adults living alone, particularly in verbal memory and fluency. This is a critical finding considering that, globally, the number of people with dementia is expected to rise from 57 million in 2019 to 153 million by 2050.
This increase in dementia cases poses a significant burden on healthcare systems and caregivers, making preventive strategies more crucial than ever.

Understanding the Study
The study used data from the English Longitudinal Study of Ageing, which included over 7,900 participants aged 50 and older. It was found that about 35% of these participants owned pets, and 27% lived alone. In this group, those who owned pets showed a slower progression of dementia symptoms, particularly in areas related to verbal memory and fluency.
Professor Ciyong Lu, a leading author of the study, emphasized the importance of these findings, suggesting that pet ownership might be a viable intervention for reducing cognitive decline in this demographic.
“Pet ownership offset the associations between living alone and declining rates [of] verbal memory and verbal fluency,” Lu told Fox News.
Caring for pets encourages a routine, adding structure to daily life in older age.
Pets and Cognitive Health
The role of pets in improving cognitive health is multifaceted. Other studies have shown that pets can reduce feelings of loneliness and isolation, which are known risk factors for cognitive decline. This effect is particularly significant for those who may not have regular interactions with other people.
The companionship provided by pets can lead to increased physical activity, such as dog walking, which studies show is beneficial for brain health. Socialization opportunities also increase when pet owners interact with others in their community.
“Research indicates that having long-term, high-quality relationships, whether that’s with family, friends, or romantic relationships, is not only important for happiness, but for promoting good brain health and reducing the risk for dementia,” Dr. Leah Croll, assistant professor of neurology at the Lewis Katz School of Medicine at Temple University told ABC News.
Pets offer emotional support, helping to reduce depression and anxiety in the elderly.
Limitations and Future Research Directions
While the findings are promising, the studies acknowledge certain limitations. For instance, the type of pet owned was not differentiated, and the continuous ownership of pets during the study period was not confirmed. Future research is needed to explore these aspects further and to determine whether specific types of pets or the duration of pet ownership have differential impacts on cognitive health.
Implications for Public Health and Individual Well-being
Pet ownership not only enhances the emotional well-being of individuals but also appears to offer tangible benefits in slowing the progression of cognitive decline, particularly in areas of verbal memory and fluency.
The correlation between pet ownership and slower cognitive decline offers a potentially significant public health intervention. As the incidence of dementia rises globally, understanding and utilizing such non-pharmacological interventions could play a crucial role in improving the quality of life for older adults living alone.
