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.
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.
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.
Severe mood dysregulation (SMD) is a very common syndrome in children. Its symptoms include very severe irritability, including persistent anger and frequent outbursts, as well as distractibility, hyperactivity, and other symptoms of attention deficit hyperactivity disorder (ADHD). Many children with SMD receive the diagnosis of bipolar disorder (BD) in the community, although they do not have clear manic episodes (with symptoms such as extreme happiness and decreased need for sleep). Because SMD has not been studied in depth, we do not know which medications are most helpful to those with SMD. This study will evaluate the effectiveness of the stimulant medication methylphenidate (MPH, more commonly known as Ritalin ) when combined (or not combined) with the antidepressant citalopram (Celexa ) in treating symptoms of SMD in children and adolescents. This study will provide information about how to treat SMD in youth. This study will include approximately 80 patients between 7 and 17 years of age with SMD. The patient s symptoms must have started before age 12. The study will consist of four phases carried out over 4 to 5 months. During Phase 1, the patient will undergo blood and urine tests, and will gradually taper off his or her medication. The duration of this phase depends on the patient s medication before starting the study. In Phase 2, the patient remains off all medication for 1 week. In Phase 3, the patient will be treated with MPH for 2 weeks, and then will be randomly assigned to receive either MPH plus citalopram or MPH plus a placebo for a further 8 weeks. In Phase 4, the researchers will evaluate the effectiveness of the medications taken, and begin an open treatment phase using medications that they deem appropriate for that patient (this may include MPH with citalopram and/or other medication combinations). 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. ...
There is growing evidence that neuropeptides act as neuronal messengers in the brain and have diverse functions that may include the regulation of mood and behavior. For example, neuropeptide Y (NPY) is thought to play a role in the adaptive stress response. The therapeutic application of neuropeptides for psychiatric disorders has been limited by difficult and unreliable penetration of the blood-brain barrier (BBB). However, recent data suggest that intranasal administration may provide a means of effectively delivering some of these neuropeptides to the brain. Thus far it is unclear if this is the case for NPY. The aims of this project are: 1. To evaluate, in 15 healthy male volunteers aged 25-45, the effect of intranasal NPY administration (0, 50 and 100 nmol) on its levels in cerebrospinal fluid (CSF), measured by means of lumbar puncture using an intraspinal catheter between L4 and L5, and in plasma, measured using an intravenous catheter in the forearm. One of the three treatments will be administered to each participant in a double-blind fashion. The 0 nmol condition will serve as the placebo control. 2. To test the effect of intranasal NPY administration on mood and anxiety.
This study will evaluate a possible tool for predicting future effectiveness of bright light in treating seasonal affective disorder, winter subtype, and will examine secondary effects of bright light on cardiovascular risk factors.
