Mood disorders, such as depression and bipolar disorder, are difficult to treat. One reason is that there are no objective ways to measure how these disorders affect the body and respond to different treatments. In this study, researchers want to perform tests on people undergoing clinical care for mood disorders. The purpose is to understand the experience of receiving treatment for depression, bipolar disorder, and suicide risk. We also hope that this study will help us to predict which medications will improve thoughts of suicide. People 18 years or older who are receiving treatment for depression, bipolar disorder, or suicide risk may take part in this study. Participants must have also been enrolled in protocol 01-M-0254. This study will be conducted at the NIH Clinical Center in Bethesda, MD. The study typically lasts up to 12 weeks, but may last longer if a participant s treatment continues past that time. Participants will have weekly interviews and questionnaires while they are being treated for their mood disorder. Other tests are optional and include psychological testing, blood draws, sleep tests, and imaging scans. These will be done at the start and the end of research participation.

This study addresses a critical unmet need in the treatment of bipolar disorder by investigating whether Subcallosal Cingulate (SCC) Deep Brain Stimulation (DBS) can safely and effectively treat treatment-resistant bipolar depression without inducing manic switches. The researchers propose to accomplish this by incorporating monitoring of the SCC local field potentials (LFP) for depression tracking and amygdala LFP monitoring for mania prediction while treating Bipolar I patients with SCC DBS Stimulation. This approach could establish a new paradigm for personalized neuromodulation therapy that uses real-time neural monitoring to optimize outcomes while minimizing risks. By incorporating bilateral, dual-site LFP monitoring from both the SCC and amygdala, this research will allow the researchers to assess the therapeutic efficacy of continuous SCC-DBS and develop novel safety biomarkers that could transform the clinical management of DBS therapy in psychiatry. The findings will have immediate implications for clinical practice and will advance the study team's fundamental understanding of the neural circuits underlying mood regulation and dysregulation in bipolar disorder.

In the treatment of Major Depressive Disorder (MDD), ketamine can produce rapid but short-lasting improvements in mood. In order to develop a new generation of treatments with rapid and sustained efficacy, a better understanding of the mechanism of action is urgently needed. One candidate mechanism is the modulation of synaptic strength mediated by glutamatergic activity as ketamine has been suggested to increase synaptic strength. Although determining how ketamine impacts the glutamatergic system is essential to isolating its mechanism of action, the invasive nature of most assessment methods has limited our ability to do so in humans. The proposed research aims to determine if changes in glutamatergic activity, reflecting the modulation of synaptic strength, underlie the antidepressant effects of ketamine. In this project, the investigators will utilize a novel measure of glutamate imaging, GluCEST, to assess changes in glutamatergic activity to assess synaptic strength following ketamine administration. Ten individuals (aged 25-65) with a DSM-V diagnosis of MDD will undergo baseline GluCEST imaging prior to and following ketamine infusion. Both clinician-administered and subjective mood measures will be collected. It is predicted that ketamine will improve mood and increase glutamatergic activity and synaptic strength. Results from this project have the potential to identify the modifiable mechanisms by which rapid antidepressants work which could ultimately stimulate the development of novel interventions that work through the modulation of glutamatergic activity.
