Filter by:The goal of this study is to develop new methods of administering antidepressant medications that will result in improved drug/placebo separation in randomized controlled trials (RCTs) for Major Depressive Disorder (MDD) and enhanced medication response in open clinical treatment. The highly intensive, weekly visit schedule followed in most antidepressant RCTs radically differs from how antidepressant medications are prescribed in standard clinical practice and is believed to be a major reason why the majority of studies submitted to the Food and Drug Administration (FDA) fail to show a significant difference between medication and placebo. Moreover, a "one size fits all" approach to psychopharmacologic management (i.e., weekly visits for all patients) does not take into account differences between patients that may predispose some individuals to respond positively to frequent follow-up visits, while others may respond negatively or not at all. Clinic visits comprise multiple components that may be therapeutic for depression, including activating patients' behavior, exposing them to medical procedures, permitting social interactions with research staff, and providing supportive meetings with clinicians. Two independent meta-analyses have associated more frequent study visits with increased antidepressant and placebo response as well as decreased separation between medication and placebo. Despite the high costs and potential disadvantages of weekly follow-up visits for patients receiving antidepressant medication, this clinical management strategy has not been studied prospectively to date. It is unknown whether weekly follow-up visits are needed to ensure treatment compliance and patient safety in clinical trials and to what degree contacts with clinicians influence medication and placebo response.
The purpose of this study is to determine whether upregulating the left amygdala during positive autobiographical memory recall via real time functional magnetic resonance imaging neurofeedback will lead to an improvement in clinician administered ratings of depressive symptoms. The investigators predict that patients with major depressive disorder receiving left amygdala neurofeedback will increase their amygdala response during positive autobiographical memory recall compared to those receiving control feedback from a region not involved in emotional processing and that this ability will be associated with clinically significant improvement.
This study will test the use of ketamine for treatment of depression in adolescents that have not responded to other treatments. We will also examine neurobiological mechanisms of treatment.
In this study, we test whether a two-week 8-session neutral attention bias modification (ABM) training and a two-week 4-session positive ABM could reduce depressive symptoms relative to placebo controls in adolescents with major depressive disorder at posttraining and follow-ups during one year.
Parent Child Interaction Therapy Emotion Development (PCIT-ED) will be conducted with a sample of preschoolers who exhibit symptoms of depression compared to a wait list (WL) control after which participants will receive the active treatment. PCIT-ED is an expansion of PCIT, a well-known, widely used and proven effective treatment for preschool disruptive disorders. To address early disturbances of mood and affect, a novel ED module was added based on empirical data in emotion development. The ED module targets parent emotion learning skills with the goal of training the parent to serve as a more effective emotion teacher and coach to the child. The goal of the ED module is to enhance the child's capacity for emotion recognition and regulation or "emotional competence." In order to test the efficacy of PCIT-ED, to estimate accurate effect sizes and to investigate mediators and moderators of treatment response participants will complete comprehensive pre-, interval, and post-assessments. Preschoolers over 3 will be offered the option of enrolling in an add-on electroencephalography and magnetic resonance imagery study, to investigate neural changes associated with PCIT-ED. Compared to those randomized to the WL, preschoolers who undergo PCIT-ED will show significantly increased rates of remission, greater reductions in MDD symptoms, and decreases in impairment; and will show significantly greater increases in emotional competence measured by the ability to accurately identify emotions in themselves and others and the ability to effectively regulate intense emotions. Compared to those on the WL, parents who undergo PCIT-ED will show significantly greater increases in emotion skill learning and reductions in MDD symptoms and parenting stress.
The purpose of this study is to evaluate the efficacy and safety of NRX-1074 following a single intravenous dose in subjects with major depressive disorder.
The purpose of the study is to evaluate effect of JNJ-42847922 on sleep latency (latency to persistent sleep) in participants with major depressive disorder who are stably treated with selective serotonin reuptake inhibitor/serotonin-norepinephrine reuptake inhibitor who suffer from insomnia (inability to fall asleep).
1. To determine the influencing factors of modified electroconvulsive therapy (MECT); 2. To determine the influencing factors and reversibility of the cognitive impairment caused by MECT; 3. To determine the duration of efficacy of MECT and its affecting factors.
The investigators have observed in an open trial that a single session of whole body hyperthermia (WBH) induced rapid antidepressant effects that persisted for at least a week in patients with major depression (MDD) severe enough to warrant inpatient hospitalization. In addition to reducing depression, the single session of WBH induced a prolonged reduction in mean core body temperature, consistent with basic science data from our group suggesting that hyperthermia activates a skin-to-brain pathway that have been shown in animals to be important for mood and body temperature regulation. Consistent with this known anatomy in our preliminary study in depressed patients, reductions in core body temperature were highly correlated with reductions in depressive symptoms over the same time period (one week post WBH). Moreover, patients with higher mean core body temperature prior to treatment had enhanced antidepressant effects. Because increased body temperature is an outcome of poor functioning in the skin-to-brain pathway activated by WBH our data suggests that WBH may actually sensitize this pathway in ways that promote changes in brain functioning known to promote emotional well-being. The results of our first open trial have encouraged us to conduct a larger, more rigorous placebo-controlled, double blind study of WBH for MDD, which is currently underway at the University of Arizona Medical School. Missing from our assessments in this ongoing double-blind study is any measure of the impact of WBH on brain function. The current proposal addresses ths gap in our investigative portfolio by proposing to conduct a second, randomized trial of active vs. sham WBH that will examine the impact of WBH on measures of brain function known from prior studies to be important for both depression and its treatment.
In this Phase 4 trial we will study the safety, tolerability and efficacy of mixed salts amphetamine (MSA), trade name Adderall, augmentation of antidepressant therapy for Major Depressive Disorder (MDD) in depressed outpatient adults who are taking an antidepressant but have not had complete resolution of their symptoms.
