A link between depression and dementia. An attempt to forget a miserable life? A post worth reading on the New York Times site:
A large body of research has linked late-life depression to social isolation, poorer health and an increased risk of death. Now, a new study finds that depression is associated with subsequent vascular dementia and Alzheimer’s disease, conditions poised to expand dramatically with the aging population.
The report, published on Wednesday in the British Journal of Psychiatry, is a meta-analysis of 23 previous studies that followed nearly 50,000 older adults over a median of five years. The researchers found that depressed older adults (defined as those over age 50) were more than twice as likely to develop vascular dementia and 65 percent more likely to develop Alzheimer’s disease than similarly aged people who weren’t depressed.
