Previous research has shown a link between depression and Alzheimer’s disease, but this is the first meta-analysis that specifically addresses the risk of Alzheimer’s disease and vascular dementia in older adults with late-life depression. The study is also the first to show that late-life depression increases the risk of vascular dementia and that the risk of vascular dementia is greater than the risk of Alzheimer’s disease for older adults with depression.
