Filter by:This study focuses on treating adolescents with depression. The study has two main purposes. The first is to compare a new form of therapy for depression called Behavioral Activation (BA) to the antidepressant medication fluoxetine. BA therapy helps depressed people get more involved in activities they find enjoyable, which can reduce symptoms of depression. Research shows that both BA and fluoxetine work to reduce depressive symptoms in adolescents. However, unlike previous research, this study examines how well the two treatment options work in comparison to each other. Participants in the study are randomized to receive treatment with either BA or fluoxetine for 18 weeks. The second aim of the study is to examine the brain functions of adolescents in both treatment groups. Participants undergo functional Magnetic Resonance Imaging (fMRI) scans before and after treatment. The data from these scans will be used to compare the brains of participants in the BA condition with those in the fluoxetine condition. Also, the scans may show possible differences between participants' brains before and after treatment. These data may help scientists determine the ideal form of depression treatment for different types of people.
The investigators are doing a research study to find out if riluzole, when taken along with a standard antidepressant (sertraline) can help people with major depression. This research study will compare riluzole + sertraline to placebo + sertraline. The investigators hypothesize that adding riluzole will lead to a better antidepressant response, in less time, then sertraline alone.
The purpose of this study is to assess the efficacy and safety of olanzapine and fluoxetine compared to placebo and fluoxetine as treatment for treatment-resistant depression (TRD) in Chinese participants.
The investigators are conducting this study to test the usefulness of a new type of analysis of electroencephalographic (EEG) recordings called brain network activation or BNA. BNA allows to identify patterns of activation in brain networks and to track their changes over time. The investigators want to examine the possible role of brain network activation (BNA) in the diagnosis of mood disorders and predicting improvement over time. The procedure conducted with patients diagnosed with a mood disorder will be compared to people who do not have a mood disorder.
Depression is common in patients with cancer. Current medications for depression, while effective, take several weeks to take effect. Ketamine has emerged as a drug with promise for cancer patients. In two reported cases, a single dose of ketamine induced rapid and moderately sustained symptom reduction in depression and anxiety with no adverse side effects. Benefit was seen in as little as 1 hour and sustained up to 30 days. This study is a randomized, double-blind, placebo-controlled investigation testing whether a single dose of ketamine improves depression and anxiety relative to placebo in patients with cancer.
In recent years, there has been growing evidence that antidepressants are only marginally effective compared to placebo for mild to moderate depression. In other words, although many people improve when they take antidepressant medications, almost as many get better with placebo pills. One possible solution to this problem would be to give patients a trail of a placebo prior to giving them an antidepressant, however there are ethical issues with doing this deceptively. New evidence from other placebo-responsive disorders such as irritable bowel syndrome shows that people may benefit from placebos even if they know they are taking them. This study aims to determine whether giving placebos without deception to people with major depressive disorder followed by the option to switch to an antidepressant is an effective strategy. There will be 3 groups of subjects. The first group is a standard treatment arm and will receive duloxetine, an antidepressant. The second will be given a placebo with the option to switch to duloxetine if they do not improve. The third group will receive supportive clinical visits the option to switch to duloxetine if they do not improve. This design will allow us to determine whether a sequenced treatment of a placebo without deception and then the option to switch to an antidepressant is a viable strategy. It will also help us to determine to what degree the benefit comes from the ritual of receiving and taking the placebo tablet versus the benefit of visits with a doctor alone. The primary hypothesis is that there will be a less than 5% difference between response rates after 12 weeks in the sequenced placebo-then-antidepressant treatment group (both subjects who have remained on placebo as well as those who have switched to the antidepressant will be considered as one group) compared to the immediate antidepressant therapy group.
This is an ancillary study to a clinical trial that is being conducted at Massachusetts General Hospital. Investigators at MGH are conducting a clinical trial to test the efficacy of ziprasidone together with escitalopram for treatment-resistant depression (NCT00633399). This observational study will involve magnetic resonance scans to examine brain chemistry (neurotransmitter levels), brain activity, and functional connections between brain regions before and after participating in the trial. The neurotransmitters of interest are glutamate, glutamine, and GABA. Comparisons will be made between individuals who receive ziprasidone and individuals who receive an inactive placebo. Differences between participants who respond to standard antidepressants and those who require additional medication will also be examined. All participants will have a baseline magnetic resonance scan before starting medication. The second scan will be after 8 weeks of escitalopram treatment for those who respond or following 8 weeks of escitalopram plus ziaprasidone or placebo (16 weeks after starting) for those who do not respond to escitalopram alone. Participants will complete standard rating scales for depression at each visit.
The investigators are doing this study to find out if they can use electroencephalographic (EEG) recordings, which measure brain waves, to predict response to antidepressant treatments, as well as to distinguish patients who have depression from those who do not. In particular the investigators want to test the usefulness of a new type of analysis of EEG recordings called brain network activation or BNA. BNA allows to identify patterns of activation in brain networks and to track their changes over time.
The purpose of this study is to evaluate the safety and efficacy of filorexant (MK-6096) versus placebo as adjunctive treatment for major depressive disorder (MDD), in participants who are partial responders to antidepressant monotherapy with one of identified selective serotonin reuptake inhibitors (SSRIs) or serotonin norepinephrine reuptake inhibitors (SNRIs), or bupropion. The primary hypothesis of the study is that filorexant is superior to placebo as augmentation therapy with respect to change from baseline to Week 6 in the Montgomery Asberg Depression Rating Scale (MADRS) total score.
This study examines whether depression in people with borderline personality disorder is different than depression in people without borderline personality disorder. Unlike people who have depression alone (i.e. without borderline personality disorder), people with borderline personality disorder have depressions that often do not improve with medications. This makes treating depression much more challenging in someone with borderline personality disorder than without borderline personality disorder. Borderline personality disorderis associated with difficulty in understanding and communicating feelings. Impaired emotion processing may reflect dysfunction of an area of the brain, the anterior cingulate. Depression is associated with changes in anterior cingulate activity. The investigators believe that when borderline personality disorder is present with depression, brain activity changes in the anterior cingulate will not be the same as in depressed patients without borderline personality disorder. An electroencephalogram records brain electrical activity. In this study, the investigators will measure electroencephalogram indices reflecting anterior cingulate activity. HYPOTHESIS: In this study, the investigators predict that when borderline personality is present with depression, electroencephalogram indices of anterior cingulate activity will be different from when depression is present alone (without borderline personality). This could help to explain why people with borderline personality have depressions that are harder to treat than depressions in people without borderline personality. The investigators also predict that electroencephalogram indices of the anterior cingulate will reflect emotional processing ability, as measured by validated questionnaires.
