Sorry cat lovers, but dogs are elderly people's best friends when it comes to helping ward off dementia, according to a recent study.
The findings show that canine ownership can lower the risk of developing dementia by about 40 percent, but feline companions do not bestow similar benefits on their elderly owners.
The probability of developing dementia was particularly low for dog owners who had a regular exercise habit and were not socially isolated.
Researchers said dogs may have helped owners get exercise and connect with local residents during walks and other activities.
The Tokyo Metropolitan Institute for Geriatrics and Gerontology analyzed new cases of dementia among 11,194 elderly people in the capital based on their nursing care insurance data between 2016 and 2020.
The average age of the subjects was 74.2. When the study started, 959 people had dogs while 704 had cats.
Dog owners were 40 percent less likely to develop dementia in the following four years, compared with non-canine owners, according to the results of the study, which were released in October.
There were no significant differences between cat owners and non-feline owners.
