Depression Clinical Trials in Pittsburgh, PA

Late-Life Depression (LLD), or depression in older adults, often presents with motivational deficits, deficits in performance in cognitive domains including processing speed and executive dysfunction, and mobility impairments. This triad of findings implicate dopaminergic dysfunction as a core pathophysiologic feature in depression, and may contribute to cognitive decline and motor disability. Normal aging results in brain-wide dopamine declines, decreased D1/D2 receptor density, and loss of dopamine transporters. Although brain changes associated with depression and aging converge on dopamine circuits, the specific disturbances in LLD and how responsive the system is to modulation remain unclear. In this study, investigators are testing integrative model that aging, in concert with pro-inflammatory shifts, decreases dopamine signaling. These signally changes affects behaviors supported by these circuits, in the context of age-associated cortical atrophy and ischemic microvascular changes, resulting in variable LLD phenotypes. Investigators propose a primary pathway where dopaminergic dysfunction in depressed elders contributes to slowed processing speed and mobility impairments that increase the effort cost associated with voluntary behavior. The central hypothesis of this study is that late-life depression is characterized by dysfunction in the dopamine system and, by enhancing dopamine functioning in the brain. By improving cognitive and motor slowing, administration of carbidopa/levodopa (L-DOPA) will improve depressive symptoms. Read Less

The investigators will administer theta burst stimulation (TBS) in efforts to observe a decrease in severity of reported depression symptoms. A subset of participants will receive positive affect training during this intervention. Read Less

This protocol will test the effectiveness of an intervention, iCHART (integrated Care to Help At-Risk Teens) and facilitate recruitment for other studies in the larger ETUDES Center grant, which are focused on treatment development for target risk factors for suicidal behavior, specifically, sleep, anhedonia, and stress related to cybervictimization. This study will recruit 900 adolescents which will be enrolled in a randomized controlled trial to test iCHART and will be randomized to iCHART or treatment as usual (TAU). Based on previous work, the investigators hypothesize that iCHART, compared to TAU, will decrease suicidal-related events by 50%, and the effects will be mediated by increases in referrals, treatment engagement, and safety planning. The investigators will use implementation science methods to assess contextual factors (i.e., barriers and facilitators) and implementation outcomes specifically, acceptability, feasibility, appropriateness, and cost for our predictive algorithm and iCHART to inform future implementation efforts and promote health equity.
