"Online engagement may help to develop and maintain cognitive reserve, which can in turn compensate for brain aging and reduce the risk of dementia," said co-author Virginia W. Chang, MD, PhD, of New York University.

It's something to be aware of if members and residents seem to be losing cognition. They may be reluctant to acknowledge vision problems.
