New research over a 28-year follow-up period finds significant evidence that frequent social contact at the age of 60 can lower the risk of developing dementia later on.
The link between having a rich social life and brain health has received much attention in the scientific community.
Some studies have suggested that levels of social interaction can predict cognitive decline and even dementia, while others have shown that group socializing can prevent the harmful effects of aging on memory.
New research examines the link between social contact and dementia in more depth. Andrew Sommerlad, Ph.D., from the Division of Psychiatry at University College London (UCL), in the United Kingdom, is the first and corresponding author of the new study.
