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.
A pilot study of mapping the peripheral plasma micro-RNA and proteomics patterns in depressive patients, treated with SSRI medications. It is an observational clinical bio-markers laboratory controlled research with no device. The research includes two groups; one for patients diagnosed of having depression, and will get a standard SSRI medication regimen. Second group is for control subjects without depression. An option for a third group is planned to include first degree relatives of the depressed patients. After giving their informed consents, subjects and patients will go through standard clinical psychiatric interview, and routine clinical lab tests. Clinical standard, specific depression and anxiety questionnaires will be held at four follow-up meetings: at start; after 2 weeks; 4 weeks; and 10 weeks. Subjects and patients will be asked to give blood samples at these points of time for the lab processing: Complete plasma proteomics and specific micro-RNA levels.
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.
The study aims to evaluate: - the frequency of subsyndromal symptoms or disorders observed during interepisode phases in bipolar patients, particularly after a depressive episode in which these subsyndromal disorders are the most frequent - the functional impact of these disorders, factors or symptom thresholds associated with functional remission, and factors associated with symptomatic remission over a sufficient follow-up (12 months).
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.
In the current study, the investigators propose to measure the five domains of social cognition identified by the National Institute of Mental Health (NIMH) as relevant to individuals with psychosis (i.e., theory of mind, attribution style, emotion recognition, social perception, and social knowledge). The investigators will also explore the association between different domains of social cognition and outcomes relevant to psychotic disorder (e.g., symptomatology, social functioning, and vocational functioning).
