Filter by:The purpose of this study is to compare the response of veterans with PTSD without an optimal response to paroxetine to quetiapine augmentation versus placebo.
Background: - The treatment of addiction often hinges on preventing relapse into drug-using behaviors, which occurs at high rates even after prolonged abstinence. Some methadone patients continue to abuse cocaine and heroin during treatment, even with extensive psychosocial services. More research is needed to look at the results from earlier studies of continued drug use during methadone treatment, focusing on the results of fixed vs. flexible doses of methadone to reduce the likelihood of continued drug use and the role of monetary vouchers as an incentive to continue abstinence from illicit substances. Objectives: - To determine if the combination of flexible methadone dosing and voucher-based contingency management can improve rates of abstinence from heroin and cocaine. Eligibility: - Individuals between 18 and 65 years of age or older who are dependent on opioids (cocaine and/or heroin). Design: - The study will last 40 weeks. After the initial screening, participants will receive daily methadone and weekly drug counseling sessions that will continue throughout the study. - After 6 weeks of methadone treatment, participants who continue to use heroin and cocaine will be randomized to one of four groups for 16 weeks of study. Each group will receive a flexible or fixed dose of methadone, and one of two contingency management conditions. - Flexible-dose participants will receive individualized dose increases, based on drug use and withdrawal. Fixed-dose participants will be set at a specific dose of methadone that will not be changed. - The two contingency management conditions will be monetary vouchers given for regular cocaine-negative urine samples, or vouchers independent of urine cocaine screen results. - After the study phase, participants will have 10 weeks of standard individual counseling and stable doses of methadone. Urine samples will continue to be collected, but no vouchers will be given. - At the end of the study, participants will have the choice of transferring to a community clinic or undergoing a 10-week taper from methadone.
The purpose of this study is to determine whether Imagery Rehearsal Therapy(IRT) is effective in the reduction of the number of nightmares and the nightmare distress in a population of patients with psychiatric disorders.
Recent studies show that 25 – 30% of depressed patients never fully recover, resulting in a treatment-resistant condition. Thus, depression is a major cause of human suffering. We are interested in finding new ways of identifying and alleviating treatment-resistant depression, and we believe that recent advances in brain imaging can contribute to achieving that goal. In this project, we will use a novel compound ([N-methyl-11C]mirtazapine) that we invented for examining the neurochemistry of brain receptors involved in antidepressant actions. Our compound, [N-methyl-11C]mirtazapine, is closely related to the clinically effective antidepressant drug mirtazapine (Remeron®). It labels several types of noradrenergic receptors that have often been implicated in “stress reactions” as well as depressive disorders. We believe that our compound can identify specific molecular brain dysfunctions that are causally related to treatment-resistant depression. The purpose of this study is to determine whether there is a reliable relationship between the level of mirtazapine in the bloodstream and the occupancy of neuroreceptors by mirtazapine in the brain. We will apply our standard procedures of PET brain scanning and region-of-interest data analysis, using healthy volunteers who will receive a daily dose of mirtazapine (double-blind design with placebo, 7.5 mg or 15 mg daily for 5 days). We believe that this project could provide a procedure for assessing brain function in treatment-resistant depression, with the aim of improving the guidelines for successful, evidence-based treatment of depression.
The objective of this study is to determine the effect of various mood stabilizers (MS) on the insulin resistance syndrome (IRS; also called the metabolic syndrome) alone and in patients treated with antipsychotic drugs (APDs). Patients will be switched from their current antipsychotic medication to aripiprazole (Abilify) or ziprasidone (Geodon) (unless clinically contraindicated) for comparison with metabolic levels during treatment with the former medication. The metabolic syndrome is an empirical concept based on extensive evidence that a constellation of 5 metabolic abnormalities, e.g. increased cholesterol, hypertension, low HDL, taken together, predict marked increases in the risk of CVD, stroke and some types of cancer.
Weight gain associated with antipsychotic medication use is a major side effect that limits the tolerability of these drugs. This often significant weight gain adversely affects health, increasing risks for developing cardiovascular disease, diabetes, sleep apnea, cancers of the colon, kidneys, uterus, endometrium and esophagus and osteoarthritis. Beasley and colleagues (1997) reported that 40.5% of olanzapine-treated patients gained more than 7% of baseline weight. Much of the olanzapine induced weight gain occurs early in treatment, and antipsychotic-naïve and young patients (Woods et al., 2002) are particularly vulnerable to this side effect. One of the most promising medications to aid weight loss in patients taking olanzapine is amantadine. Attempts at preventing weight gain are expected to be more successful than attempts to reverse it once it occurs. It is now common clinical practice to educate all patients beginning treatment with olanzapine, and other antipsychotics, about healthy eating and the need for exercise. However, despite this effort, weight gain in this population continues. Beginning a weight-stabilizing medication after a low threshold of weight gain has occurred may have significant impact on patients' health and their willingness to continue to take antipsychotics. We propose to investigate the efficacy of amantadine as a weight-stabilizing agent in a population of first-episode psychotic subjects just beginning treatment with antipsychotic agents. This population is generally young and medically healthy, without contraindications to amantadine. They are often of normal body mass index and without obesity-related medical problems. They have much to gain in preventing the weight gain which so often progresses steadily over the course of treatment, is difficult to reverse and results in significant morbidity and mortality. Additionally, the first episode psychotic population tends to take fewer concomitant psychiatric medications. This is important since these medications may cause weight gain (long term use of mirtazapine, lithium, depakote) or weight loss (short term use of SSRI's) which could confound the effectiveness of amantadine to combat weight gain.
The purpose of this study is to investigate the efficacy and safety of FK199B (Zolpidem MR Tablet) in patients with insomnia by a randomized, double-blind, group-comparison study using zolpidem (Myslee) as a comparative drug
RATIONALE: Photodynamic therapy uses a drug, such as HPPH, that is absorbed by tumor cells. The drug becomes active when it is exposed to light, and kills tumor cells. HPPH may be effective in killing precancerous cells and tumor cells. PURPOSE: This randomized phase II trial is studying how well photodynamic therapy with HPPH works in treating patients with precancerous esophageal conditions or stage 0 or stage I esophageal cancer.
This study is designed to examine the efficacy of a cognitive behavioral therapy (CBT) program for treating anxiety symptoms, social problems, and adaptive behavior deficits in children with autism spectrum disorders.
This study will compare two programs to see if they are helpful in preventing the use of substances in adolescents with attention deficit-hyperactivity disorder (ADHD), oppositional defiant disorder (ODD), or conduct disorder (CD). One of the programs involves working with adolescents and their parent(s) in their home. The other program involves working with adolescents and their parent(s) in an office setting.
