Depression Linked to, but Not Precedent of, Mild Cognitive Impairment

​More than 2,000 community-dwelling Medicare beneficiaries age 65 or older were assessed for mild cognitive impairment and progression to dementia in conjunction with late-life depression. The study, results of which were published online December 31, 2012, in JAMA Neurology (formerly Archives of Neurology), found that participants with depression had a higher risk of having been diagnosed previously with mild cognitive impairment and that participants with mild cognitive impairment and depression were likelier to progress to dementia.
