A Multi-level Life-span Characterization of Adult-depression and Effects of Medication and Exercise
In Brief
A Phase 4 clinical trial evaluating Venlafaxine XR, Aerobic Exercise, and 1 other intervention for Depression and 4 related conditions. Completed, enrolled 31 participants across 1 site.
Detailed Summary
This pilot study aims to test a model that predicts that enhanced neurotransmitter gamma-aminobutyric acid (GABA) function in reward and affect-regulation central nervous system (CNS) circuits mediates the antidepressant effects of exercise. State-of-the-art magnetic resonance (MR) imaging, cognitive assessment, accelerometry, genetic, and inflammatory biomarkers will be acquired through the coordination of efforts from several established research programs at Western Psychiatric Institute and Clinic. This pilot study will be used as a platform for testing a causal/mediating role of GABA interneurons in reward processing and affect regulation in humans. This pilot study is not powered for testing a full causal model, but rather is intended to test overall feasibility of the intervention and acquisition of measures (see specific aim 1 below). This is a necessary prerequisite for designing a larger more definitive study of the model, which will be a component of a future grant application. Additionally, the data from this study will be used to test the clinical efficacy of exercise as an adjunctive treatment for late life depression (LLD; Specific Aim 2), as well as imaging, cognitive, and sleep aims (Specific Aims 3 and 4).

Timeline
Interventions
Lorazepam may be used in the study for patients who either are already on this drug or who need it for sleep and/or anxiety. Patients taking another benzodiazepine will be asked to convert from their current benzodiazepine to an equivalent dose of Lorazepam (2mg or less in 24 hours). This will be administered in pill form.
