Summary

"This trial is observing patients with bipolar depression who haven't responded to treatment, and they are being given ketamine intravenously. The study also includes using fMRI to understand the effects of ketamine

Who is the study for?
This trial is for individuals with bipolar depression who haven't improved with standard treatments. Participants will receive intravenous ketamine and undergo brain scans using fMRI. Specific eligibility details are not provided.
What is being tested?
The study observes the effects of IV ketamine on patients with treatment-resistant bipolar depression, while also monitoring changes in their brain activity through functional magnetic resonance imaging (fMRI).
What are the potential side effects?
Ketamine may cause side effects such as disorientation, nausea, increased blood pressure, mood swings, or dissociative experiences during infusion. The fMRI procedure is generally safe but can be uncomfortable due to loud noises and confined space.
