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.\n\nPeople 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.\n\nThis 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.\n\nParticipants 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.

Stated willingness to comply with all study procedures and availability for the duration of the study.\n3. 18 to 70 years of age.\n4. All participants must have undergone a screening assessment under protocol 01-M-0254.\n5. Participants must fulfill DSM-IV or DSM-5 criteria for MDD, single episode or recurrent without psychotic features, based on clinical assessment and confirmed by a structured diagnostic interview (SCID-P).

Participants must have an initial score of \\>= 20 on the MADRS and a YMRS score of \\\u003C12 within one week of study entry and upon entry into Phase II.\n7. Ability to take intravenous medication and be willing to adhere to the (2R,6R)-HNK regimen.\n8. Participants must have a current or past history of lack of response to at least one adequate antidepressant trial (may be from the same chemical class), with at least one in the current major depressive episode, operationally defined using the modified Antidepressant Treatment History Form (ATHF); non-response to an adequate trial of ECT or TMS would count as an adequate antidepressant trial.\n9.

They will stay off of the drugs for up to 2 weeks prior to starting the study medication and procedures. They will have a physical exam with blood tests. They will have tests of their heart function, mood, and thinking. They will answer questions about their symptoms. They may choose to have imaging scans and scans of their brain activity.\n\nHNK is given through a tube attached to a needle inserted into a vein. Participants will receive infusions on this schedule:\n\nThey will receive 4 infusions over 2 weeks. They will stay in the clinical center overnight after each infusion or for the duration of the study.\n\nThey will receive no drugs for 2 to 3 weeks.\n\nThey will have 4 more infusions over 2 weeks, with overnight stays after each or for the duration of the study.\n\nOne set of 4 infusions will be the HNK.
