Natural History of Depression, Bipolar Disorder and Suicide Risk

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.

Precision Subclassification of Mental Health in Diabetes: Digital Twins for Precision Mental Health to Track Subgroups

Mental conditions and disorders (e.g. distress, depressive, anxiety, and eating disorders) are more prevalent in people with diabetes (PWD) and associated with reduced quality of life and impaired glycaemic outcomes. Evidence supports a complex network between psychosocial factors and glycaemic control that can be highly variable between persons. It is assumed that subgroups exist that show different trajectories of glycaemia and mental health. Belonging to a particular subgroup may be linked with a higher risk of developing mental health problems compared to others. This suggests that it is possible to treat individuals in different subgroups in a manner that optimizes their treatment and can improve health outcomes. Accurate characterisation can inform more individualized care. This calls for a more personalised approach considering the idiosyncrasies of different subgroups. Over 3 years, the investigators have established the basis of a precision mental health approach for diabetes using n-of-1 analyses. By utilizing combined ecological momentary assessment (EMA: repeated daily sampling of psychosocial factors in everyday life) and continuous glucose monitoring (CGM), intensive longitudinal data per person could be collected. This enables the analysis of individual associations between glycaemic parameters and psychosocial variables and identification of individual sources of diabetes distress in each person. The objective of the present study is to use of the n-of-1 approach to identify subgroups of PWD who share common characteristics in the associations between glucose and psychosocial variables. The identified subgroups shall be used to develop a digital twin for precision mental health in diabetes. The digital twin serves as representation of a real person, allowing to make simulations and predictions of the course of mental health and glycaemia. These predictions can inform diabetes care and lead to more precise, personalised treatment decisions. To achieve this, a longitudinal panel including over 1,400 PWD who continuously complete EMA and questionnaire surveys and measure glucose levels using CGM was developed. Over 1000 clinical interviews to diagnose mental disorders have been conducted to identify major mental health conditions and map mental outcomes. To identify subgroups and develop the digital twin, the sampling will be expanded aiming at a total of 1,809 PWD. Incidence and remission of mental disorders will be determined via repeated interviews. The complex networks between clinical, metabolic, and psychosocial data will be analysed using machine learning, leading to new insights with the potential to shape future guidelines. These results will be used by the digital twin to predict courses of glycaemic control and mental health, translating the individual evidence into direct treatment suggestions.

Mental Health Mission Mood Disorder Cohort Study

The current study aims to understand why some people with depression respond to treatment and others do not, using markers of clinical symptoms, both clinician reported outcome measures and patient reported outcome measures, demographic information, cognitive function, genetic sequence information (genomic), chemical measures of metabolism (metabolomic), protein makeup (proteomic) and the body's natural defence system (immune/inflammatory markers) together with collections of cells that will facilitate new research to drive improvements in diagnosis and treatment of mood disorders that may be proving difficult to treat. This will allow future clinical trials within the NHS, academia and industry to drive forward new approaches and treatments. Participants who provide consent for re-contact for future treatment trials and other research studies have the potential to benefit from this with participation in experimental studies and clinical trials associated with improved patient outcomes. Overall, the cohort will generally support greater access to research opportunities for a wider population of people.

Optimal Electrical Stimulus During Electroconvulsive Therapy

Synopsis Aim: The purpose of the study is to determine the stimulus of electrical current during electroconvulsive therapy (ECT) that produces the optimal balance between antidepressant effect and memory disturbance. Specifically, this study aims to compare the 0.5 ms and 1.0 ms pulse width stimuli. Design: National, register-based randomized trial, unmasked with two treatment arms. Primary objective: To test the hypothesis that a 1.0 ms pulse width stimulus produces a higher remission rate (\< 11 on the MADRS-S) than a 0.5ms pulse width stimulus. Secondary objectives include testing for differences in: self-rated global health measured with the EQ5D-VAS subjective memory worsening (increase of 2 on the memory item of the CPRS) antidepressive response (decrease of 50% on the MADRS-S) number of ECTs in the treatment series readmission and suicide rate within 6 months Study population: patients with unipolar or bipolar depression. Sample size: 800 patients, 400 patients in each arm. Inclusion criteria: At least 18 years of age at the time of inclusion Diagnostic criteria fulfilled for unipolar, or bipolar depressive episode according to ICD-10.

BioClock: Bright Light Therapy for Depressive Disorders

Bright Light Therapy (BLT) is a proven treatment for depression in seasonal and non-seasonal depressive disorders, as well as bipolar disorder. To make BLT more effective and practical in clinical settings and tailor it to individual needs, it is necessary to optimize the treatment approach, understand how the treatment works, and identify patient characteristics that predict response. This clinical trial has three main goals: * Optimize the administration of BLT for patients with depressive episodes. * Gain a deeper understanding of the treatment mechanisms. * Determine which patients benefit the most from the treatment. The specific objectives are as follows: * Investigate whether additional treatments and interventions related to lifestyle and the biological clock can enhance the effects of BLT. * Examine how BLT influences the body's internal clock and sleep quality, and how these factors contribute to the outcomes. * Identify patient characteristics and behaviours that can predict treatment outcomes. * Develop a brain model to better understand the impact of BLT on the brain. In this study, patients will receive BLT with a light intensity of 10,000 lux for 30 minutes each morning over 5 consecutive days. The treatment duration will range from one to three weeks, depending on the improvement of depressive symptoms. Participants will be randomly assigned to one of three groups: * Home - Patients will receive BLT at home, following the standard guidelines for light therapy in the Netherlands. * LightCafé, fixed time: Patients will receive BLT in a café-like setting called the LightCafé, where the focus is not only on symptom improvement but also lifestyle enhancements and fostering social connections. The treatment time will be the same every day. * LightCafé, varying time: Patients will also receive BLT at the LightCafé, with treatment timing varying each day. Additionally, this group will wear glasses in the evening that filter blue light. The study includes a baseline phase of up to two weeks, a treatment phase of up to three weeks, and a three-month follow-up phase. Patients will wear a motion watch to assess sleep-wake behaviour and physical activity during the day. Additionally, they will wear a broach that measures their personal light exposure throughout the day. Eight one-minute questionnaires per day will be sent to the participants' smartphones to assess vitality, sleep, and mood during the treatment. Predictors of treatment response, such as clinical characteristics, sleep measures, circadian parameters, and light-related behaviours, will be evaluated at baseline. In a small group of patients, salivary melatonin curves will be assessed before and after treatment. MRI scans will provide insights into functional and structural brain changes following light therapy treatment.

Ketogenic Diet for Depression

Globally, it's estimated that around 300 million people are affected by depressive illness, and even with access to modern mental health care, long-term recovery is uncommon. Recently, there has been increasing interest in a promising intervention: the ketogenic diet. This diet restricts carbohydrate intake, promoting the breakdown of fats into circulating ketone bodies, which can act as an additional energy source for the brain, potentially reducing its reliance on glucose. While various sources of evidence suggest the potential benefits of the ketogenic diet for individuals with depression, robust clinical studies on its efficacy in depressed patients are lacking. Our goal is to conduct an eight-week, assessor-blinded, randomized controlled trial to investigate the therapeutic effects of a very low-carbohydrate, high-fat ketogenic diet compared to an active comparator diet in individuals with depression.
