Some people might not mind spending time alone, but new research with data from 18 countries suggests that older people who struggle with loneliness — rather than strictly being alone — may experience a faster mental and physical decline.
The study, led by the University of California, Davis, used advanced statistical modeling to chart loneliness and social isolation as older adults move through stages of cognitive impairment and mortality. The results suggest that loneliness plays a much stronger role in cognitive impairment and shorter life spans than social isolation on its own.
Depression may shape how much children pay attention to emotional expressions – sad or happy faces – and those changes appear to depend on whether the child has a family history of depression, according to a first-of-its-kind study from Binghamton University, State University of New York.
