Filter by:The purpose of this study is to characterize the behavior of cardiac patients with Mood Disorders and its clinical course, interpreting the results from a theoretical framework of Chaos Theory and Complexity Theory and Systems as well.
The purpose of this study is to determinate the effect of a pre-treatment with carvedilol, a alpha- and beta-adrenergic receptor blocker, on the pharmacodynamics and pharmacokinetics of 3,4-methylenedioxymethamphetamine (MDMA, "Ecstasy"). The investigators hypothesize that carvedilol will attenuate the cardiovascular and subjective response to MDMA.
The purpose of this study is to get a better understanding of the side effect burden and identify predictors of psychotic, mood and aggressive disorders in children and adolescents. The study's primary aim is to identify genetic risk factors for weight gain and metabolic abnormalities.
The purpose of this study is to determinate the effect of a pre-treatment with centrally acting alpha2-receptor agonist clonidine on the pharmacodynamics and pharmacokinetics of 3,4-methylenedioxymethamphetamine (MDMA, "Ecstasy"). The investigators hypothesize that clonidine will attenuate the subjective and cardiovascular response to MDMA.
The purpose of this study is to determinate the effect of a pre-treatment with the combined serotonin (5-HT) and norepinephrine (NE) transport blocker duloxetine on the pharmacodynamics and pharmacokinetics of 3,4-methylenedioxymethamphetamine (MDMA, "Ecstasy"). The investigators hypothesize that duloxetine will attenuate the subjective and cardiovascular response to MDMA.
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.
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.
The purpose of this project is to assess the effectiveness of a family-based therapy (Attachment based family therapy-ABFT) for Norwegian adolescents (13-17 years) referred to specialist mental heath clinics.
