Assessing Anterior Cingulate Brain Activity in People With Late-Life Depression
Recruitment status was Recruiting
This study will examine differences in activity of the anterior cingulate cortex, a brain area involved in emotion and cognitive regulation, between older adults with and without depression.

Elderly participants who have never experienced depression
Older adults with depression often also suffer from executive dysfunction—problems with planning, impulse control, and reasoning. Executive dysfunction in older adults predicts poor or delayed response to antidepressant treatment and has been associated with early relapse and recurrence of late-life major depression. Functional magnetic resonance imaging (fMRI) is a scan that can measure the activity of someone's brain while that person performs tasks. So far, no fMRI studies investigating cerebral activation patterns in late-life depression have been published. In this study, people will undergo fMRI while they are performing an executive function task. Older adults with late-life depression and older adults without depression will be tested and compared in order to identify the areas and patterns of brain activity underlying executive dysfunction in late-life depression.
Participation in this study will consist of one study visit, during which participants will undergo an fMRI scan that will last 60 to 90 minutes. While being scanned, participants will perform cognitive tasks that involve pressing buttons in response to words viewed on a screen.
