Brain Insulin Resistance in Mood Disorders
Major Depressive DisorderBipolar Disorder2 moreThe overarching aim of the study is to determine the role of insulin signaling on the neurobiological substrates subserving anhedonia within individuals with mood disorders (i.e., Bipolar Disorder (BD) and Major Depressive Disorder (MDD)). Specific aims include: Molecular: Assessment of components of the insulin cascade, as well as of anhedonia and reward-related processes, using a proteomics and gene expression approach; Physiology: Measurement of peripheral sensitivity to insulin and metabolic correlates, including body mass index and dyslipidemia; Neural Circuits: Evaluation of the insulin sensitivity of prefrontal (e.g. prefrontal cortex) and striatal (e.g. nucleus accumbens, ventral tegmental area) networks in the resting-state and during an effort-based decision making test, using acutely administered intranasal insulin and functional magnetic resonance imaging (fMRI); Behavioral: Measurement of willingness to make effort for rewards, as well as of other components of reward response and anhedonia, using validated behavioral tasks and clinical scales (e.g. Snaith-Hamilton Pleasure Scale - SHPS). This initiative represents a proof-of-concept study that insulin is important to anhedonia, neurocognitive functioning, and behavioural deficits in MDD, representing a novel and safe therapeutic avenue.
Effects of an ER Beta Agonist (Lilly Compound LY500307) on Estradiol-Withdrawal-Induced Mood Symptoms...
Perimenopause-Related DepressionBackground: Some women who had depression in the perimenopause may have mood symptoms again if they stop estrogen therapy. Estrogen acts in the brain and other tissues by binding to at least three types of estrogen receptors. One of these receptors, estrogen receptor beta may affect anxiety and depression. The drug LY500307 acts only on this receptor. In this study, researchers will initially give you estrogen and then suddenly stop estrogen after three weeks. Then they will study how LY500307 affects mood symptoms. Objectives: To study how withdrawing estradiol affects mood. To test the safety and side effects of LY500307. Eligibility: Healthy women ages 45-65 who had depression related to perimenopause in recent years and whose mood systems got better with estradiol Design: -Participants will be screened with: Medical history Physical exam Blood tests Psychiatric interview Gynecological exam Participants able to get pregnant must use effective barrier birth control throughout the study. During the first 3 weeks, participants will wear an estrogen patch. It is 1x2 inches and will be replaced every 3 days. For the next 3 weeks, participants will take 3 study capsules every morning. They will not know if they get the study drug or placebo. Some participants will also take a progesterone-like drug for 1 week at the end of the medication phase of the study. Participants will have 9 one-hour study visits. They will have blood samples and vital signs taken. They will answer questions about mood and behavior symptoms. Participants will keep a daily log of these symptoms. Participants will have 2 transvaginal ultrasounds. A probe is temporarily placed 2-3 inches into the vaginal canal and sound waves are used to create pictures of the lining of the uturus. Participants will have a final visit 4 weeks after stopping the study drug. They will answer questions about mood and side effects.
Efficacy of Light Therapy Device LUMINETTE® in Major Depressive Disorder
Major Depressive DisorderUnipolar DepressionThis study evaluates the addition of light therapy with LUMINETTE device to usual treatment (antidepressant drug and psychotherapy) in the treatment of Major Depressive Disorder (MDD). Half of the participants will receive active light therapy with LUMINETTE device while the other half will receive placebo light therapy with LUMINETTE placebo device.
Xenon Inhalation Therapy for Major Depressive Disorder and Bipolar Disorder
Major Depressive DisorderBipolar DepressionThe investigators will test the hypothesis that inhaled xenon will produce a rapid improvement in depressive symptoms in patients suffering from treatment-resistant depression. Specifically, the investigators will conduct a parallel randomized, double-blind crossover study that will compare the effects of xenon-oxygen (35:65 ratio by volume) added to treatment as usual (X-TAU group) to the effects of nitrogen-oxygen (35:65 ratio by volume) added to treatment as usual (N-TAU group). A total of 20 severely depressed patients, 10 with major depressive disorder (MDD) and 10 with Bipolar Depression (BP), will be exposed in random order to N-TAU and X-TAU in a double-blind protocol.
Mindfulness and Relaxation Interventions in Individual Psychotherapies for Children and Adolescents...
Hyperkinetic DisorderDepressive Disorder1 moreThe study 'Mindfulness and Relaxation interventions in Individual Training Psychotherapies for Children and Adolescents' (MARS-CA) aims to examine the effects of short session-introducing interventions with mindfulness elements (SIIME) on juvenile patients' psychopathological symptomatology and therapeutic alliance at the beginning of the first 24 therapy sessions.
RCT Comparing EMDR and CBT for Treatment of Resistant Depression
Eye Movement Desensitization and ReprocessingCognitive Behavioral Therapy5 moreDepression is one of the most common invalidating mental disorders, ranked by World Health Organization as the single largest contributor to global disability. Current recommended treatments for depression include antidepressant medication and according to guidelines, Cognitive Behavioral Therapy (CBT) and Interpersonal Therapy (IPT). Despite encouraging preliminary results (e.g., Matthijssen et al., 2020), Eye Movement Desensitization and Reprocessing (EMDR) therapy is not yet recognized as an effective therapy for depression by APA and NICE. The project aims to conduct a large multisite study that addresses the shortcomings of previous efficacy research on EMDR for depression. The primary aim is to evaluate the effectiveness of EMDR therapy in reducing depressive symptoms in adults with major depression as compared to CBT. Secondary aims of the study are the effectiveness of EMDR, as compared to CBT and TAU, in improving anxiety, and other symptoms. It is hypothesized that EMDR is not inferior to CBT.
Feasibility of a Group Blended Transdiagnostic CBT Protocol for Emotional Disorders
Anxiety DisordersDepressive DisorderThe aim of this study is to analyze the feasibility of a blended transdiagnostic group protocol for the treatment of depression and anxiety disorders (emotional disorders) in a one-group clinical trial.
The BIomarker Guided Study for Depression
Major Depressive DisorderThe diagnosis of major depression relies on patient reports, and two patients with the same diagnosis might share only one symptom. Thus, a single mechanism is unlikely to underlie a broad descriptive diagnosis such as major depression. Our approach is anchored by a neural circuit taxonomy that proposes distinct biotypes of depression derived from functional magnetic resonance imaging (fMRI) (Williams et al., 2016). In this study, we aim to target a putative type of major depression that arises from dysfunction in cognitive control neural circuitry with a drug called guanfacine.
A Randomized Controlled Study of Digitalized Cognitive Behavioral Intervention for Antenatal Depression...
DepressionAntenatal DepressionThe main objective of the current research project is to evaluate the effectiveness of the digitalized cognitive behavioral therapy program including telephone coaching for antenatal depressive symptoms. The participants are screened from the general population of pregnant women, as a part of the routine maternity health care check-ups. Mothers with depressive symptoms will be randomized into intervention group receiving guided digitalized treatment program or control group receiving education material about depression in digital form.
Scopolamine in Bipolar Depression
Bipolar Disorder DepressionThis is a single-site, randomised, double-blind, placebo-controlled, parallel, phase IIb clinical trial. The primary objective of the SCOPE-BD study is to investigate the efficacy and safety of IV Scopolamine, compared to placebo, in reducing severity of depression in individuals with bipolar disorder who are experiencing a depressive episode of at least moderate severity
