Active clinical trials for "Anxiety Disorders"

Pharmacological interventions to aid behavior management's techniques are commonly used in pediatric dentistry. The aim of the medicaments is to control behavior and allow safe completion of a dental procedure. Homeopathic remedy is safe and can be effective to control behavior and decrease anxiety in children during dental treatment. Aim: 1. To explore the efficacy of homeopathic drugs in decreasing children's dental anxiety before dental treatment. 2. To assess the effectiveness of homeopathic remedy in facilitating dental treatment for anxious children. Methods: prospective, double-blind study. Thirty healthy children (5-12 years-old) will receive homeopathic remedy\placebo before dental treatment. Anxiety reduction will be measured using: saliva cortisol levels, saliva α-amylase levels, facial image scale (FIS), and Houpt behavior scale. Expected results: the homeopathic remedy will reduce anxiety and increase child cooperation during dental treatment.

The purpose of this study is to evaluate the potential efficacy of JNJ-42165279 in treating anxiety disorders through evaluation of brain activation patterns using imaging technology in healthy volunteers.

This research study aims to test the feasibility and effectiveness of using the Mayo Clinic Anxiety Coach smartphone app as an addition to traditional therapy for the treatment of anxiety disorders in youth, particularly those youth who may have limited access to mental health treatment in the traditional clinical setting.

Objective: The overall aim of this protocol is to examine the effect of pharmacological manipulations of affective and cognitive processes on anxiety and task performance. Ultimately, the goal is 1) to provide insight into the relative influence of cognitive and affective states on anxiety, 2) generate theoretical models that can be applied to a better understanding of the interaction between cognition and emotion, 3) develop a better screening approach to candidate anxiolytics, and 4) help formulate novel therapeutic interventions for clinical anxiety. Excessive or inappropriately sustained anxiety and fear lead to the most common group of psychiatric disorders. A number of theoretical models have been proposed to understand the mechanisms engaged in these maladaptive behaviors. Most recent emphasis has focused on the synergistic contribution of cognitive and emotional processes. Our laboratory has been instrumental in delineating aspects of behavioral and neural processes that are associated with fear and anxiety, using psychophysiological and neuroimaging measures of fear and anxiety. Evidence shows that levels of anxiety modulate cognitive performance, such as working memory or perceptual discrimination, and that, conversely, cognitive engagement influences severity of experimentally induced anxiety. The exact contribution of emotional processes vs. cognitive processes to the experience of anxiety is not clear, similarly to the neural mechanisms underlying these interactions. In this protocol, we propose to manipulate pharmacologically separately cognitive and emotional processes to dissociate their contribution to fear/anxiety, while using state-of-the-art measures of anxiety derived from translational work. Indeed, we already developed integrative experimental models of fear and anxiety via the manipulation of predictable and unpredictable shock, respectively. We already employed successfully these models to measure anxiolytic and anxiogenic effects of various compounds such as alprazolam, citalopram, hydrocortisone, and oxytocin in healthy participants. We propose in a first step (step-1) to start with a simple proof-of-concept study, using two pharmacological compounds in a double-blind randomized parallel design, each preferentially acting respectively on the cognitive (methylphenidate) or affective (propranolol) domain, and using a single cognitive process (working memory). In a second step (step-2), we propose to extend this work to the fMRI to examine the cognitive correlates of the effects seen in the step-1 behavioral study, specifically with methylphenidate. Whereas the comparison among three drugs is planned for the electrophysiology study, we plan to study only the drug that improves cognition in the fMRI. The reason we will focus on methylphenidate in step 2 is that our overall goal is to study the effect of improving cognitive functions on anxiety using neuroimaging. To reach this goal, we plan to use different approaches to boost cognitive functions in the coming years, including psychopharmacology, direct current stimulation, mindfulness. Methylphenidate is our first psychopharmacological study towards this objective. Future work will also expand to other compounds and cognitive processes, as well as vary the strategy to induce anxiety. Presently, anxiety will be induced using the threat of shock, while participants perform the task. We will examine in step-1 whether 1) the reduction of induced-anxiety with propranolol improves cognitive performance, and 2) the facilitation of cognitive performance with methylphenidate reduces induced-anxiety. In step-2, we will identify the neural mechanisms underlying the effects of methylphenidate, the drug having beneficial effects on cognitive function. Study population: Medically and psychiatrically healthy adult males and females, aged 18 to 50 years. Design: The study is a double-blind design. For step-1, three groups of healthy participants will come for one experimental session. During this session, they will be asked to perform a working memory task under the threat of shock, i.e., while anticipating unpleasant electric shocks. Each group will receive one drug challenge, either placebo, propranolol (40 g) or methylphenidate (20 mg). For step-2, the study tasks will be conducted in a 3T fMRI scanner. In this step, only methylphenidate and placebo will be compared. Two groups will come for one experimental session, one will receive placebo and the other one will receive methylphenidate (20 mg). In a follow-up study for the step-2 fMRI the two groups will come for one experimental fMRI session one will receive methylphenidate (60 mg). Outcome measures: In step-1, the primary outcome measures are the startle reflex and performance on the working memory task. In step-2, the primary outcome measures are the startle reflex and the cerebral fMRI blood-oxygen-level ...

This randomized pilot clinical trial studies the feasibility of a pre-operative and/or post-operative scripted sexual health informational intervention and how well it works in improving sexual function in patients with gynecologic cancer. Discussing sexual outcomes and counseling options with patients may help improve sexual outcomes and/or anxiety after primary gynecologic cancer treatment.

The purpose of this study is to determine whether Guided Imagery and Progressive Muscle relaxation are effective as stress reducing techniques in parents of hospitalized children with cancer.

Dental anxiety is a significant barrier to the acceptance of regular dental care, and has many negative consequences. A study by Dailey et al. (2002) found that providing the dentist with information of the high level of a patient's dental anxiety prior to treatment using the Modified Dental Anxiety Scale (MDAS, Humphris et al., 1995), lead to a significant reduction in state anxiety from pre- to post- dental consultation compared to a control group. The current study aimed to replicate the study by Dailey et al. (2002), and to further explore whether the reduction in state anxiety associated with the MDAS could be explained by a change in dentist behaviour on receiving it, or a change in patient expectancy about the treatment session, or both. The design was a randomised control trial involving three groups, which aimed to manipulate possible changes in dentist behaviour and patient expectancy. In Group 1, the MDAS was left at reception, as expected by the patient. In Group 2, the dentist received the MDAS, although the patient did not expect this. In Group 3 the dentist received the MDAS and the patient did expect this. The sample (N=182) was taken from two dental access centres, and included participants obtaining a score of 19 or above, or 5 on any one item of the MDAS. Pre- and post-dental consultation measures of state anxiety were taken using the six-item short-form of the state scale of the Spielberger State-Trait Anxiety Inventory (STAI-S, Marteau & Bekker, 1992).

Background: - Baclofen is a drug used to control muscle stiffness in people with neurological diseases. Some studies suggest that baclofen may reduce alcohol craving and use. It helps to reduce anxiety in alcoholics, which in turn can help to reduce cravings. Researchers want to see if baclofen can be a safe and effective treatment for alcoholics who have high anxiety levels. Objectives: - To see if baclofen is safe and helpful for people who have alcoholism and high anxiety levels. Eligibility: Individuals between 21 and 65 years of age who have been diagnosed with alcoholism and anxiety issues. Participants must not be taking anti-anxiety medication. Design: Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. Tests of alcohol dependency and anxiety levels will also be given. Participants will be divided into two groups. One group will take baclofen. The other group will have a placebo. About 1 week after the screening visit, participants will have a study visit. They will answer questions about their behavior and mood. They will then start to take either baclofen or a placebo. Participants will take the study drug three times a day, every day. After 1 week on the study drug, participants will have an overnight stay at the National Institutes of Health. They will have blood tests and answer questions about mood and behavior. They will also have tests that involve choosing to drink alcohol and answering more questions about cravings. Participants will stop taking their study drug over a 3-day period. A final follow-up visit will be required 1 week after the overnight study visit. Participants will receive information about other alcohol abuse treatment programs.
