Research: Active Social Life Aids Memory
Harvard professor, Karen Ertel, the lead researcher in the study has been quoted as saying: "This adds to a body of literature that really is showing pretty strong support that social activity and engagement may have a protective effect on cognitive decline."
Of course, the study has much to say to RTs who may provide social stimulation for clients that may well help them with cognitive functioning.
The study was published in the American Journal of Public Health. Unfortunately, it is not yet available eletronically so I've only been able to read a newspaper account on the research (that appeared in today's Indianapolis Star). I'll see what I can do to find the origional reseach article when it becomes available.
