The Week - Having a dog or cat appears to slow cognitive decline in older people, according to a new study from the University of Maryland. Nearly 650 people 50 and over and in good health at the start participated in the study, with about a third owning a pet. They were given cognitive tests at intervals over 13 years, and while all experienced some degree of mental decline, the deterioration was generally slower in those who had pets. Researchers noted that pet ownership has already been associated with lower levels of stress, heart disease and, in the case of dogs, increased physical activity; it may also combat social isolation and loneliness, which have both been linked to cognitive decline. Their findings, the researchers said, suggest that efforts should be made to ensure older people are able to live with pets.
