Filter by:The purpose of this study is to identify evidence-based guidelines for treating major depressive disorder to full remission in Taiwanese major depressive disorder (MDD) patients. To achieve this goal, the investigators aim to: (1) evaluate the risks and benefits of adjunctive pharmacotherapies for cognitive and metabolic consequences in MDD, and (2) clarify the shared biological mechanisms between mood, immune and metabolism homeostasis
Considering the potential modulatory effects of Salvia divinorum, Lycium, Chenpi and Dihuang supplementation on mood, this study is a clinical study of Soline® (product mixed with Salvia divinorum, Lycium, Chenpi and Dihuang ) supplementation to investigate the effect of attenuating the occurrence of depression. The study will enroll 100 patients who meet the inclusion and exclusion criteria. The trial will be concluded when a total of evaluable 80 patients (40 patients in each treatment group).
We propose to study approach/avoidance behavior as measured by the Approach Avoidance task in 20 epilepsy patients undergoing implementation of depth electrodes for seizure monitoring in the Epilepsy Monitoring Unit at MGH. We will also study the effects of VC/VS electrical stimulation on approach-avoidance conflict in 20 adult patients who have undergone DBS implantation for severe MDD and/or OCD. There are 100-200 patients in the world with DBS electrodes in the VC/VS, and our research team cares for more than any other institution. Both participant groups will be assessed with respect to reward-aversion decision conflict using the task. The task will be performed with concurrent EEG recordings in DBS patients, and with continuous recording through our invasive neurophysiology rig in EMU subjects.
Primary Outcome Measures: Evaluate the changes in neuroimaging and biochemistry measures with ketamine treatment. Secondary Outcome Measures: Evaluate the effects of ketamine on depression symptoms, manic symptoms, global change in psychiatric symptoms, and suicidal ideation.
The purpose of this study is to see how an insulin sensitizing medication, Pioglitazone, can cause changes in mood in some depressed patients. Study participants receive assessment of their cognitive and metabolic functioning. If they meet criteria, they will be asked to take either Pioglitazone or a placebo for a 90-day trial. Participants will undergo an Oral Glucose Tolerance Test to measure fasting insulin and glucose levels, as well as routine blood testing. The investigators hope to quantify the role of Pioglitazone in patients with mood disorders and compare the values to those previously obtained in a healthy age-matched control population. The investigators also hope to examine the association between IR and cognitive performance and clinical course of depression in patients with mood disorders.
The goal of this project is to study the course and outcome of illness in individuals who present with a first episode of depression or mania, or who have a recurrent disorder but have never received treatment. We plan to examine psychological, physical, social and environmental factors that may affect long-term outcome in these disorders
Subjects with major depression will be evaluated and intensively characterized through questionnaires, computerized cognitive evaluation and laboratory investigations. Magnetic resonance imaging will be used to document baseline white matter structure. subjects will then receive desvenlafaxine which will be adjusted as clinically indicated. After 16 weeks the evaluations will be repeated.
This study aims to identify a novel enhancement strategy for residual symptoms of major depressive disorder (MDD) Dopamine (DA) has been viewed as a "pleasure neurotransmitter" for over 30 years. Yet recent data from animal and human studies suggest that dopamine has greater effects on "wanting" than on "liking." Therefore, the investigators of this study have hypothesized that amphetamine/d-amphetamine (AMPH), a medication which increases dopamine transmission in the reward centers of the brain, may have a more powerful antidepressant effect in combination with well-being therapy (WBT), a specific type of cognitive-behavioral therapy, which helps individuals with depression to increase their contact with natural rewards and decrease reward-interfering thoughts. The investigators will test their hypothesis by randomizing 40 individuals with residual symptoms of depression, already taking an antidepressant that affects serotonin (e.g. Prozac, Paxil), to 8 weeks of treatment with either WBT in combination with AMPH, or WBT with pill placebo. The effectiveness of each treatment will be measured using a reliable scale, called the Hamilton Depression Rating Scale. The investigators have also hypothesized that people assigned to the stimulant/WBT group will have greater improvements in functioning, well-being, and positive affectivity than those the people assigned to the WBT/placebo group.
Study hypothesis: psychotherapy and SSRI treatment effect in different brain way: psychotherapy in "up to down" way and SSRI in "down to up" way. The investigators will explore this hypothesis in major depressive disorder outpatients with Magnetic Resonance Imaging analysis in this study. Patients in different groups will be treated by psychotherapy or SSRI treatment. They will all be checked with Magnetic Resonance Imaging pro and after 12 weeks of treatment.
Recently, interest has emerged in the use of ketamine as an antidepressant. Recent placebo-controlled clinical trials administering a single dose and an open label trial giving repeated doses shown that ketamine is markedly superior to placebo at reducing depression, including in treatment-resistant patients, and that its antidepressant effects have a very rapid onset. This clinical study consists of two phases. In Phase I, participants who satisfy inclusion criteria will receive ketamine at variable doses (0.1mg/kg-0.5mg/kg) or a placebo (saline, or 0.01mg/kg midazolam) once a week over up to 6 weeks. If participants qualify for Phase II, they will receive repeated sessions of ketamine at variable doses over three weeks. During both phases, mood, psychiatric, and neuropsychological outcomes will be measured.
