Published: Jan 02, 2013
Depression in a group of Medicare recipients ages 65 years and older appears to be associated with prevalent mild cognitive impairment and an increased risk of dementia, according to a report published Online First by Archives of Neurology, a JAMA Network publication. Depressive symptoms occur in 3 percent to 63 percent of patients with mild cognitive impairment (MCI) and some studies have shown an increased dementia risk in individuals with a history of depression. The mechanisms behind the association between depression and cognitive decline have not been made clear and different mechanisms have been proposed, according to the study background.
