Filter by:About one-third of depressed patients will not get better after multiple antidepressant treatments. This situation put a high burden on patients with depression due to worsening quality of life and increasing health care costs. Difficult-to-treat depression might be even worse among Veterans given that the frequency of depressive symptoms is 2 to 5 times higher than among the general US population. A breakthrough discovery happened in recent years when investigators found that one infusion from an old anesthetic named ketamine showed high efficacy and rapid antidepressant effect (sometimes within hours) but lasted only up to a week. The investigators propose to study if multiple infusions of ketamine can provide greater and longer antidepressant effects than one infusion. If that is the case, multiple infusions could be an alternative to relieve depressive symptoms that do not response to multiple antidepressant drugs.
This study evaluates the efficacy of vitamin D replacement therapy in reducing depressive symptoms in patients with chronic liver disease and vitamin D deficiency. Patients with normal vitamin D levels will be monitored as controls, and they will not receive any intervention.
Patients whose kidneys fail generally require dialysis treatments to sustain life. The ability of patients to make major adjustments in their lives for dialysis is hampered by depression that affects almost one-quarter of such individuals. There are no studies that have adequately tested whether treatment of depression is effective in dialysis patients and if there is any difference between the response to the two most commonly available forms of treatment, psychotherapy and anti-depressant drug therapy. To fill this important gap in the investigators knowledge, the investigators propose to undertake (1) a randomized controlled clinical trial of 200 patients to test whether an engagement interview will result in a higher proportion of dialysis patients accepting treatment for depression; and (2) a randomized controlled clinical trial of 120 patients to determine whether there is any difference in the likelihood of improvement of depressive symptoms with psychotherapy or drug therapy among dialysis patients with depression. Patients in these studies will be enrolled from among individuals receiving care in 50 dialysis facilities in three metropolitan areas - Seattle, Dallas, and Albuquerque. The research proposal has been developed with the support of patients, caregivers, and stakeholders to ensure that the findings from the study are relevant to them and can be readily implemented in day-to-day clinical practice. Hence, the engagement interview and psychotherapy will be delivered in a dialysis facility to ease the burden on patients, and the dose of the study drug will be changed in partnership with the study participants. In addition to depressive symptoms, the effect of treatment on other meaningful outcomes such as fatigue and sleep will be determined. The two forms of treatment for depression being tested in this clinical trial are very different from each other and patients differ with regards to the treatment option preferable and/or available to them. Successful completion of the clinical trial will provide patients, caregivers, and other stakeholders with the information that they would need when faced with a diagnosis of depression in patients undergoing hemodialysis. This will allow patients to select evidence-based treatments to improve outcomes that are relevant to them.
The investigators hypothesize that the administration of two widely available, naturally occurring dietary supplements, 5 hydroxytryptophan and creatine monohydrate, will reduce the severity of depression in individuals exposed to chronic hypoxia by living at altitude. The purpose of this study is to determine if 8 weeks of dietary augmentation with oral 5 g creatine daily and 100 mg 5-HTP twice daily reduces hypoxia-related depressive symptoms measured by the 17-item Hamilton Depression Rating Scale (HAM-D) in women with SSRI or SNRI-resistant depression.
This study is intended to compare the acceptability and feasibility and explore outcomes related to two different formats of a parenting program for mothers with postpartum depressive symptoms. One version will be a traditional, in-person group format, while the other will be a social media group format. The investigators will also explore the differences in outcomes of both formats, looking at depressive symptoms, parenting sense of competency, and parenting interactions with children.
The investigators will determine whether an acute dose of nicotine, in the form of the nicotine lozenge, impacts brain and behavioral measures of mood and reward responsiveness in individuals with major depressive disorder.
The purpose of this study is to determine whether gamma-Hydroxybutyrate (GHB) has prosocial and prosexual effects in healthy male participants, and to characterize these putative effects via behavioral tests, functional magnetic resonance imaging (fMRI), electroencephalography (EEG), and neuroendocrine parameters. The investigators predict that GHB in fact has prosocial and prosexual effects which can be neurobiologically characterized using the assessed methods. Such effects would be of high interest for the treatment of mental disorders which involve impairments of social interaction and sexual function such as major depression or autism.
The purpose of this study is to provide knowledge regarding the effect of early intervention and prevention on the development of anxiety and depression in children. The focus of the intervention is to reduce symptoms of anxiety and depression and help children develop skills to enhance self-esteem in order to improve life quality. Gender and ethnicity will be studied as moderating factors. Primary care givers will be trained in the use of evidence based methods for children with internalizing difficulties. Children in need will be identified and receive improved services, based on international standards. Active collaboration will be established nationally between three Centers for child and adolescent mental health (RKBU/RBUP) and internationally with Philip C. Kendall at the Temple University in Philadelphia and Kevin Stark at University of Texas at Austin. Primary aims are to examine if an indicated group and school based program, Coping Kids, is more effective than treatment as usual (TAU) in reducing high levels of symptoms of both anxiety and depression among 8-12 year old schoolchildren, and if the the effects are stable over 12 months.
The purpose of this study is to determine whether auricular acupuncture (AA) according to the NADA protocol and progressive muscle relaxation (PMR) differ in their effectiveness of treating people with anxiety disorders or major depressive disorder. We hypothesized, that both treatments show significant effects in alleviating the examined items (tension, anxiety, anger/aggression and state ofr mood) and that there is no significant difference between these two treatments.
