Background: More than 12,000 people have taken part in research at the Experimental Therapeutics & Pathophysiology Branch at the National Institute of Mental Health Intramural Program. This has led to advances in the treatment of depression, bipolar disorder, and suicide risk. Researchers want to follow up with this group to see if they continue to have mental health symptoms and receive psychiatric treatments. Objective: To learn the long-term impact of depression, bipolar disorder, and suicide risk. Eligibility: Adults ages 18 and older who signed consent for Protocol 01-M-0254 over a year ago. Design: This study has 2 phases: an online phase and a telephone phase. It has no in-person or face-to-face contact. In Phase 1, participants will fill out online surveys. They will access the surveys through the study website. The questions will focus on their current thoughts and feelings. The surveys will also ask about their current treatments for their mental health symptoms. At the end of the surveys, they will be asked if they would like to take part in Phase 2. If so, they will mark yes. Phase 2 includes a phone interview. They will be contacted by email to schedule the interview. In Phase 2, participants will be asked more in-depth questions about how they are feeling. They will also be asked which psychiatric medicines and treatments they have used since they left NIH. In both phases, participants can skip any questions they do not want to answer. The online surveys will take 30 minutes to complete. The phone interview will last 1-4 hours. The information that participants give in this study may be linked to their other NIH research records.

The present study is an open trial of ketogenic diets for adolescents and young adults (ages 12-21 yrs) in the depressive or mixed phases of bipolar disorder (BD). The investigators aim to determine whether combining standard of care pharmacological treatment for bipolar spectrum disorders with a 16-week ketogenic diet is well-tolerated and associated with improvements in depression, inflammatory and metabolic indicators, and executive functioning over the study period. The experimental treatment in this study is a 16-week full ketogenic diet. Four study sites (UCLA, U Cincinnati, U Colorado and U Pittsburgh) will recruit 80 total youth (20 each) from bipolar specialty clinics. All youth eligible for the ketogenic therapy will be provided with the ketogenic diet and standard of care pharmacological treatment. During the diet therapy youth will be seen by a study child/adolescent psychiatrist at least once a month (and more frequently when needed), with the psychiatrist recommending and providing side effects monitoring and pharmacotherapy as clinically indicated. The youth and caregivers will also meet with an expert dietitian who will coach all youth on maintaining the ketogenic diet (low carbs, high fats, medium protein) and making sure the child is tolerating the diet and getting enough liquid and nutrients, following the practice guidelines of the International Ketogenic Diet Study Group for treating youth. All youth and involved caregivers will also be provided will at least one motivational enhancement session to support them in goal setting and completion of the study elements. Throughout the study the investigators will assess metabolic (e.g., blood ketones, HOMA-IR) and inflammatory indicators (e.g., C-reactive protein), both for safety reasons and to assess correlates of symptomatic change. Independent evaluators will assess youth every month regarding their symptoms (depression, mania, anxiety, psychosis), psychosocial functioning, and quality of life. The investigators anticipate that the pilot will transpire over 24 months and be an important step toward establishing feasibility and acceptability of ketogenic therapy for this population, not only in terms of diet administration and compliance but also for obtaining symptomatic, metabolic and inflammatory measurements.
