Emotional Cognition: Establishing Constructs and Neural-Behavioral Mechanisms in Older Adults With Depression

Active Not RecruitingN/A

Sponsor: University of Texas Southwestern Medical Center

Conditions: Major Depressive Disorder (MDD), Healthy Adult Volunteer

Interventions: Hot Cognitive Task, Cold cognitive tasks, Structural magnetic resonance imaging (sMRI), Magnetoencephalography imaging (MEG), four self-report forms per the requirement of the NIH Common Data Elements project

Countries: United States

This is a cross-sectional pilot study designed to establish hot and cold cognitive functions and underlying neurocircuitry in older adults with MDD. The investigators will study 120 participants aged 21-80 years old with MDD. All participants will undergo clinical and neurocognitive assessment, and Magnetoencephalography (MEG)/Magnetic resonance imaging (MRI) procedures at one time point. The investigators will also enroll 120 demographically matched comparable, never-depressed healthy participants (controls) to establish cognitive benchmarks. Healthy controls will complete clinical and neurocognitive measures at one time point. To attain a balanced sample of adults across the lifespan, the investigators will enroll participants such that each age epoch (e.g., 21-30, 31-40, etc.) has a total of ten subjects (n=10) in both the healthy control cohort and depressed cohort.
