Loneliness is linked to dementia. A number of studies over the years have suggested that. Now, a team at Florida State University College of Medicine has combed through that information for the largest review of its kind. The conclusion is the same—that loneliness increases the risk of dementia by more than thirty percent. Authors of the study in Nature Mental Health say the results are not surprising given that loneliness is linked to poor health in general. This solid evidence provides the basis for future prevention and intervention against loneliness, as well as supporting the well-being and cognitive health of aging adults. One other observation from the study is that while loneliness is prevalent in the elderly, it affects people of all ages.
