Depression, diabetes linked to increased dementia risk
Depression and type 2 diabetes were each associated with an increased risk for dementia. The risk was even greater among individuals diagnosed with both depression and diabetes, according to work led by University of Washington School of Medicine researchers. The findings appeared April 15 in JAMA Psychiatry.
Investigators examined the risk for dementia among individuals with depression, type 2 diabetes or both compared with individuals with neither condition in a group of more than 2.4 million Danish citizens, who were 50 and older and free from dementia from 2007 through 2013.
Dr. Wayne Katon, a noted researcher on the associations between depression and chronic disease, was the lead author of the study, which was published posthumously. He was a UW professor of psychiatry until his death March 1, 2015 at age 64.
