Filter by:Suicide attempts are a serious concern worldwide. Currently, existing drugs take about three weeks to show effect on suicidal thoughts and drives. Recent evidence suggests that intravenous Ketamine exerts a rapid effect in suicidal patients, even after a single injection. We aim to examine whether oral Ketamine is a safe and effective treatment in suicidal patients. Following a suicide attempt, patients will be randomized into a group that will be given Ketamine for 21 days and one that will receive placebo, and assessed using questionnaires and brain scans. We expect early improvements in suicide scales in the Ketamine group. As a secondary goal, this study will use IV ketamine in order to access the extent to which the experience of the embodied self mediate different levels of "embodied emotion". A better understanding of these relations will assist in unveiling the cognitive mechanism underlying the therapeutic effect of ketamine
Major depressive disorder (MDD) is one of the most common psychiatric disorders, with high recurrence rate, suicide rate and disability rate. It's reported that the global burden caused by MDD will be up to the second rank among all the disease burdens by 2020. China is also confronted with the daunting challenges against MDD. It's assessed that the monthly incidence of MDD is 6.1%, non-hospitalizing rate reaches up to 92% and the non-treatment rate is approximate 95%. However, to date, the pathogenesis of MDD is obscure and the current therapies don't work well. Therefore, it's urgent and critical to elucidate the pathogenesis of MDD, to develop early diagnostic criteria and effective intervention in MDD. Considering the diversity of weights on genetic factor and environmental factor in MDD, in this project, the investigators aim firstly to explore the effect of "genetic-environmental interaction"on the pathogeny of MDD for classifying MDD into "genetic type", "environmental type" and "others" based on a case-control study. We next conduct the neurobiological, neurocognitive and psycho-behavioral assessments among MDD, schizophrenia and healthy groups to screen the salient endophenotypes for establishing the diagnostic models of MDD . The investigators further analyse the changes of these indicators after 8 weeks'medication to select the potential predictors for therapeutic evaluations and interventional options in MDD patients. Finally, the investigators continue a 2-year follow-up study to test and verify the predictors of prognosis in MDD patients.

This research study will examine if a targeted computerized cognitive remediation (CCR) training program is better for treating geriatric depression than general computer activity. We will also examine whether this intervention is related to improvement in cognitive and depressive symptoms. Elderly patients with depression, who have, and who have not been treated with antidepressant medication for their illness, will be recruited to participate in either a 30 hour cognitive remediation program or general computer activity designed to be both challenging and interesting. They will be asked to complete between 1 and 3 hours of remediation per day over 4 weeks. While undergoing the cognitive remediation participants will be asked questions to assess their symptoms of, as well as the severity of, their depression weekly. This will inform researchers about whether or not the CCR is helping to improve depressive symptoms. At the end of the CCR study, participants will be given a battery of cognitive tests design to tell investigators whether or not the CCR improved their thinking in a variety of different ways including improving attention, memory, and organization. Investigators will also determine whether changes in participants' thinking are related to changes in their mood or other depressive symptoms. It is hoped that information gained from this study will help investigators to better understand the brain processes associated with depression, recovery from depression, and will help inform the development of future alternative treatments for this illness.
Cognitive Behavioral Therapy for Insomnia (CBT-I) has been proven as an effective intervention for the non-pharmacological treatment of insomnia. This study hypothesizes app programs of smart phone would enhance the compliance and performance of behavioral intervention of CBT-I. During a 3-year study period, 3 app modules, including electronic sleep diary along with message reminder system, social persuasion system and Tai-Chi practice system will be tested subsequently for their efficacy.
A multicenter, 10-week study to evaluate the efficacy and safety of Sustained-Release Desvenlafaxine Hydrochloride versus Sustained-Release venlafaxine Hydrochloride in adult with major depressive disorder.
To examine the efficacy and safety of treatment with desvenlafaxine for vascular depression. Primary efficacy, as it pertains to depressive symptoms, will be assessed by overall change in symptom severity score from baseline to 12-weeks, measured by the Geriatric Depression Scale. The primary efficacy measure of cognition will be the Montreal Cognitive Assessment and analysis of change between baseline and 12-week scores. To evaluate the effectiveness of desvenlafaxine as a first-line treatment for vascular depression in a sub-group of patients who have experienced a TIA greater than 6 weeks prior to baseline. Mean differences between baseline and 12-week efficacy measures will be examined within the sub-group.
OBJECTIVE: Evaluate the effectiveness of quality of life score, a cognitive-behavioral intervention by psychologists in the field of primary care in anxiety-depressive patients, mild to moderate, compared with usual care. DESIGN: Clinical trial, multicenter, prospective, and randomized into two parallel groups. SCOPE AND SUBJECTS: We included a random sample of 246 patients anxious-depressive, mild / moderate, belonging to the target population of 41 doctors from several health centers. INTERVENTION: In the 246 patients randomly assigned to the intervention group, with a standardized program of cognitive behavioral therapy applied by psychologists, by the usual treatment or control group, which will be standard care. MEASUREMENTS: The main result will be changes in general health scores of the SF-36. It will also measure the change in frequency and intensity of anxiety-depressive symptoms on the scales HARS, HDRS, STAI and BDI at baseline and at 2, 6 and 12 months. In addition, also collected for drug use and health services. ANALYSIS: Analyses were performed by intention to treat, comparing the change obtained in both groups at the end of the 12 month follow up. Estimates of the effect attributable to the intervention by the difference in those changes, adjusting in addition to the baseline, the possible confounding covariates or effect modifiers of the intervention, using longitudinal mixed-effects models.
The mechanisms of oxidative stress and inflammation involved in mood disorders are factors of chronicity and severity. These mechanisms induce a phenomenon of accelerated cellular senescence and are reflected by alterations in systemic gene expression detectable in leukocytes in peripheral blood. The genetic markers of these mechanisms are clinically significant markers. The identification of new genetic markers will make it possible to improve evaluations of the severity and somatic consequences of depressive syndromes.
The purpose of this study is to determine whether combination of antidepressant drugs plus interpersonal psychotherapy is superior to antidepressant drugs alone in treatment resistant depression.
