Clinical Trial Summary

This multi-modal methods study will investigate neurophysiological, endocrinological, cognitive, psycho-social-emotional markers of disease, and targets for integrative health treatments in mood disorders.

Clinical Trial Description

It is estimated that 16.2 million adults in the USA suffer at least one depressive episode any given year. Mood disorders are associated with decreased quality of life, attention, memory, and executive function deficits, and increased health care cost. Despite successful medication and psychotherapies, mood disorders rarely respond completely to common treatment options. MBI's offer a low-cost, non-pharmacological alternative with accruing efficacy. Developing robust and specific non-pharmacologic intervention programs, on par with pharmacological clinical outcomes without harmful side-effects is a crucial unmet clinical need and a research priority for the NCCIH. Understanding the mechanistic pathways of these interventions is key to their clinical development and implementation for treating depression in primary care. Mindfulness-Based Interventions (MBIs) show similar clinical efficacy for mood disorders as pharmacology, and co-morbid symptoms of depression and anxiety. There is substantial consistent and replicated empirical evidence across multiple clinical sites highlighting the clinical efficacy of MBI in decreasing risk of depressive relapse ascertained from randomized RCTs comparing MBI with treatment as usual. Meta-analysis including 183 patients with Multiple Sclerosis showed efficacy in psychosocial outcomes, quality of life, anxiety, depression, and select physical symptoms including fatigue, pain, and vestibular symptoms. The clinical efficacy of MBIs appears to extend mood disorders, as a systematic review including 13 studies in fibromyalgia, chronic fatigue, and irritable bowel syndrome showed significant effect sizes, reported as standardized mean difference (SMD), compared to control conditions in reducing depression (SMD= -.23), anxiety (SMD= -.20), symptom severity (SMD= -.40), and pain (SMD= -.21). Cognitively, MBIs appear to enhance executive control and self-regulatory processing, that has a beneficial effect upon emotion regulation, pain perception, and has shown to reduce rumination in depression. This overarching study aims to identify key phenotypic markers and treatment targets of mood disorders, and further understand MBI mechanism in its treatment. ;
