A study conducted by the Tokyo Metropolitan Institute for Geriatrics and Gerontology reveals that elderly individuals who own dogs experience a 40% lower risk of developing dementia, while owning cats has a marginal effect.
The research, involving 11,194 participants aged 65 to 84, analyzed data collected between 2016 and 2020. The odds ratio for dementia risk was calculated at 0.6 for dog owners and 0.98 for cat owners, compared to 1 for those without pets.
Yu Taniguchi, a senior researcher, interprets the findings, noting that dog ownership facilitates daily exercise habits and social participation, leading to a reduced dementia risk. The study, published in Preventive Medicine Reports, emphasizes the positive impact of physical activity and social engagement through dog care in preventing dementia among older adults.
The Tokyo Metropolitan Institute of Gerontology’s research, involving 12,000 residents, underscores that dog ownership encourages leaving the house, increasing human-to-human interaction, and exercising the brain.
Even after adjusting for background factors, owning a dog exhibits a suppressive effect on dementia development over a four-year period. The study suggests that dog care contributes to maintaining physical activity and social participation, essential factors in preventing cognitive decline, especially during challenging times like the COVID-19 pandemic.
