People who develop depression, MCI after age 65 are more vulnerable for accelerated brain aging

People who develop depression and mild cognitive impairment (MCI) after age 65 are more likely to have biological and brain imaging markers that reflect a greater vulnerability for accelerated brain aging, according to a study conducted by researchers at the University of Pittsburgh School of Medicine. The findings were published online in Molecular Psychiatry.
