This research study evaluates the effects of anFDA-approved medication Gabapentin in individuals with Bipolar Disorder who smoke marijuana. Participants in the study will will be assigned to take either Gabapentin or a matched placebo. Study medication will be taken for 17 days. There will be 5 study visits, with 2 MRI brain imaging scans completed. Questionnaires and clinical interview measures will be completed at study visits along with consistent assessment of potential side effects from study medication.

Patients with cardiovascular disease (CVD) are at increased risk of depression following hospital discharge. Unfortunately, most depressed CVD patients do not receive appropriate care for their depression, often because they are unable to, or are fearful of traveling to providers for the regimen of 8-12 weekly visits of therapy such as Behavioral Activation (BA). This study will compare the effectiveness of BA for depression, delivered via Telehealth, to standard post-CVD hospital discharge best practices. It is predicted that patients who receive BA will have better mental health outcomes and will be less likely to be re-hospitalized compared to patients who receive standard post-discharge care.

Depression is a very common disorder that is most often chronic or recurrent in nature. Many subjects do not respond adequately to an initial antidepressant treatment trial. Subjects who do not respond adequately to multiple therapeutic interventions are considered to have treatment-resistant depression (TRD). Among the treatment options for subjects with TRD is Vagus Nerve Stimulation (VNS) Therapy.This blinded, randomized, multicenter controlled study is intended to collect evidence that VNS Therapy as an adjunctive therapy improves health outcomes for patients with TRD.

This is an open-label study designed to investigate the feasibility and tolerability of a novel TMS treatment protocol to treat depression in women with post-partum depression. It is known that TMS can effectively treat depression. The FDA approved protocol lasts 6 weeks and is not feasible for many women with post-partum depression. In this study we are investigating 2 accelerated treatment delivery schedules: One in which patients receive treatments on 6 days over 3 weeks and one in which treatments are delivered on 5 days within 8. We are investigating the feasibility, tolerability, and credibility of both schedules which may be more acceptable for this population. We further hope to characterize the anti-depressant effect and durability of this protocol in order to design a larger trial.

Aerobic exercise training has positive effects on depression severity and mood in individuals with depression. The effects of single sessions of aerobic exercise may also provide some short-term benefits in depression. It is believed that a reduction in depression severity may be facilitated by changes in the nervous system, however this has yet to be examined. Although aerobic exercise has beneficial effects for those with depression it is unclear as to why this may occur. Therefore the goal of our project is to better understand the effect of a single session of aerobic exercise on the nervous system, physiology, and mood in depression.
