PITTSBURGH - Pitt researchers say older adults with major depression have double the risk of developing dementa as those who've never had a mood disorder. The scientists say blood tests, PET scans and MRIs suggest that the brains of people with depression and mild memory loss age more quickly which puts them at risk for developing dementia.
Researchers say if they can understand what happens in the brain when this occurs, they may be able to develop ways to slow or stop the impairment from progressing to dementia.
