Filter by:The purpose of this study is to determine whether a newly developed, brief cognitive behavioral intervention, relative to supportive counseling, is effective in reducing acute stress disorder (ASD) and preventing post traumatic stress disorder (PTSD) and depression.
The investigators have developed an intervention called Behavioral Treatment of Smoking Cessation in SPMI (BTSCS), an innovative intervention that supplements pharmacotherapy and education with contingency management and a multifaceted behavioral group treatment program that lasts for three months (24 group meetings). BTSCS is designed to address the cognitive, motivational, and social support problems characteristic of people with SPMI. The investigators propose to conduct a randomized trial for persons with SPMI that compares (1) BTSCS: a 6-month manualized smoking cessation program adapted from an effective substance abuse treatment program for this population to (2) StSST: a standard manualized smoking cessation program which reflects current best practices.
Depression and bipolar disorder (mania and depression) may be related to problems with nerve cells not being regenerated as fast as normal and are accompanied by cognitive difficulties including memory, attention and planning problems. There is thus a need for better, more efficient treatments with effects on cognitive function. Erythropoietin (Epo) is involved in brain repair and may be a candidate for future treatment strategies. The investigators have demonstrated that a single dose of Epo improves mood and reduces the processing of negative emotional information in healthy volunteers similar to effects seen with antidepressants. With the current study the investigators aim to build upon this discovery by investigating whether repeated Epo administration has antidepressant effects and is able to reverse cognitive difficulties in patients with depression or bipolar disorder. It is hypothesized that Epo will improve mood in treatment-resistant depression and improve cognitive function in this group and in patients with bipolar disorder in remission. If the study reveals beneficial effects of Epo, this would highlight Epo as a candidate compound for future treatment of depression and bipolar disorder, with the potential to directly promote brain repair mechanisms.
The objectives of this study are to evaluate the efficacy and safety of quetiapine extended release tablet versus placebo as adjunct to selective serotonin reuptake inhibitors/serotonin/norepinephrine reuptake inhibitors (SSRI/SNRI) in the augmentation treatment of patient with primary anxiety disorders or mood disorders with co-morbid anxiety symptoms.
The purpose of this study is to help us understand how depression changes brain activity and how this relates to mood, anxiety, and cognitive functions like memory. We also hope to develop a brain imaging test that will predict either before or within two weeks of starting a medicine whether the treatment will work.
MDMA (3,4-Methylenedioxymethamphetamine, "Ecstasy") produces tachycardia, hypertension, hyperthermia, and other acute adverse effects. Ecstasy use has also been associated with rare cardio- and cerebrovascular complications. The role of beta-blockers in the treatment of cardiovascular and adverse effects of MDMA is unknown.
MDMA releases dopamine, serotonin, and norepinephrine in the brain. Serotonin uptake inhibitors have been shown to interact with 3,4-Methylenedioxymethamphetamine (MDMA) and to decrease its psychoactive and cardiovascular stimulant effects. This finding indicates that MDMA acts in part by releasing serotonin through the serotonin uptake site. However, in vitro studies show that MDMA binds more potently to the norepinephrine uptake site that to the the serotonin or dopamine uptake transporter. In addition, norepinephrine uptake site blockers such antidepressant drugs attenuate some of the behavioral effects of MDMA in animals. These preclinical data indicate that norepinephrine may also contribute to the response to MDMA in humans. To test this hypothesis this study evaluates the interacting effects of the selective norepinephrine transporter inhibitor reboxetine on the subjective and cardiovascular stimulant effects of MDMA in healthy volunteers.
The purpose of this research study is to see how certain hormones cause changes in mood and thinking in some depressed patients and to determine the effectiveness of mifepristone in treating some forms of depression. This study is conducted in conjunction with an observational study "Clinical and Biological Characteristics of Psychotic Depression".
This is a randomized, controlled clinical trial of inactivated negative ion generation or light-emitting photodiode therapy for Seasonal Affective Disorder (SAD, winter depression), for subjects with a DSM IV diagnosis of Major Depression, with Seasonal Pattern, Winter type, to examine efficacy of treatments for this condition. The trial has a 1 week baseline phase and a 4 week treatment phase.
Pediatric Bipolar Disorder (BD) is uncommon in children. Its symptoms include periods of manic behavior (being overly happy or giddy, feeling grandiose, feeling a decreased need for sleep, having too much energy, moving more than usual, talking fast, having speeded-up thoughts and other symptoms). Sometimes there also is depression (extreme feelings of sadness or irritability, not taking pleasure in things, even ones that used to be enjoyable, feeling worthless or guilty, sleeping too much or having trouble getting to or staying asleep, feeling slowed down or restless, having wishes to be dead or suicidal ideas, and other symptoms). Pediatric BD is often difficult to treat; children may respond only partially to the medications now available or have too many side effects to tolerate them. Riluzole is a medication that is thought to work on a brain chemical called glutamate that may be involved in symptoms of depression and BD. Previous research studies have shown that riluzole may help adults with BD who have depression and adults who have depression, anxiety disorders, or obsessive-compulsive disorders. Riluzole may also be helpful for children with obsessive-compulsive disorder. However, it has never been given to children with BD. This study will evaluate the effectiveness of riluzole in 80 patients between 9 and 17 years of age who have BD and symptoms of anxiety. Participants must have tried at least two other medications that have not been effective. The study will consist of four phases carried out over 4 to 5 months. Most children will be inpatients at the Pediatric Behavioral Health Unit for at least part of the study. In Phase 1, each patient will undergo blood and urine tests, and will gradually taper off his or her medication. The duration of this phase depends on the medication that the patient was receiving before starting the study. In Phase 2, the patient will remain off all medication for 1 week. Throughout this time, patients will be monitored carefully and medication will be restarted if needed. In Phase 3, which lasts 8 weeks, patients will be assigned randomly to receive only riluzole or only a placebo. Those who receive riluzole will have the dose adjusted as needed. Patients and families will be informed of which drug they were on at the end of this phase. Patients who improved on riluzole may continue to receive it from NIH for 1 month and will then be prepared for discharge from the study. Patients who received placebo and improved, and those who received riluzole but did not improve, will be treated with standard medications as appropriate and prepared for discharge from the study. Phase 4 is for patients who received placebo and did not improve. They will be given the chance to try riluzole for 8 weeks and, if it is effective, continue it for an additional 4 weeks while they prepare to be discharged from the study. Patients will not be able to receive riluzole at the National Institutes of Health after the completion of the study. However, the child's doctor may be able to prescribe riluzole as an off-label use. Most patients will be admitted to the Pediatric Behavioral Health Unit at the National Institutes of Health Clinical Center during the medication withdrawal part of the study (Phases 1 and 2). From Phase 3 on, a patient may participate as an inpatient, outpatient, or in day treatment, depending on what is in his or her best interests. All participants in this study will be invited to also enroll in the National Institute of Mental Health protocol 00-M-0198, The Phenomenology and Neurophysiology of Affective Dysregulation In Children And Adolescents With Bipolar Disorder. Some research tests for that protocol will be done during the medication-free period of this protocol.
