Scientists have pointed to the role of social isolation in old age

A study by the University of St. Andrews has shown that social isolation accelerates cognitive decline in old age. This discovery revealed that even in the absence of feelings of loneliness, people who are socially isolated face a more rapid decline in mental abilities. This was reported on December 16 by Medical Xpress magazine.

Unlike loneliness, which is subjectively felt by people, social isolation is measured objectively through such parameters as sociability, participation in public organizations and religious events.

Researchers from the University of St. Andrews, the Max Planck Institute and Emory University analyzed data from more than 30,000 people and 137,653 cognitive function tests conducted from 2004 to 2018. The findings showed that reducing social isolation has a positive effect on the cognitive functions of all groups, regardless of gender, race, ethnicity, and educational level.

Before the coronavirus pandemic, about a quarter of people over the age of 65 considered themselves socially isolated. This has raised some concerns about the health consequences, and loneliness has been recognized as a serious public health problem in high-income countries.

"During the holidays, many of us think a lot about how important it is to be surrounded by family and friends. From pagan winter holidays to classic Christmas tales, we are reminded that social interaction is good for our mental health," said the study's lead author, Dr. Joe Hale from the University of St. Andrews.

According to him, the study demonstrates the importance of social interaction for cognitive health. The specialist stressed that creating conditions for regular social interaction for the elderly, including those who do not have family or friends nearby, should become a priority in the field of public health.
