An article authored by a group at the University of Pittsburgh today published an article in the British Journal of Psychiatry confirming and extending our 2006 paper in the Archives of General Psychiatry showing that depression is related to an increased risk of developing dementia later in life. Our previous paper showed that having a diagnosis of depression increased someone’s risk of being diagnosed with Alzheimer’s disease. The new study includes studies we didn’t include and expands the analysis to include risk for vascular dementia, a type of dementia related to problems with the blood vessels in the brain.
A post on the New York Times blog “The New Old Age” puts the studies in context and explains what they mean — thanks to Judith Graham for her cogent explanation of the importance of the new study. She quotes me as well as co-author David Loewenstein on the meaning of the new study. You can read her article here.
You can find the abstract of the new study here. (You need a subscription to read the full article.)
Our original paper in the Archives is available in a slightly different version (but full text) here.
