Active clinical trials for "Anxiety Disorders"

70% of Europeans will be exposed to a potentially traumatic event (PTE). Following this experience, people are likely to develop various psychiatric disorders such as post-traumatic stress disorder (PTSD) or a major depressive episode (MDE). However, not all subjects have the same risk to develop a pathology, and resilience capacities, which depend on multiple factors are difficult to predict. Currently, there are no objective tools to stratify exposed subjects according to their risk of developing pathological responses to stress, which leads to difficulties in allocating means of prevention and treatment. Recently, new biological hypotheses explaining vulnerability/resilience to stress and depression, implicating the GPR56 and ELK1 genes, have been described. Previous studies have shown that evaluation of the vulnerability risk can be obtained from clinical, cognitive, biological or brain imaging variables, but no study has integrated these different approaches. Therefore, the project presented here aims at integrating behavioral, biological and neuroimaging data to predict the development of psychiatric disease. In this study, a prospective cohort of 255 violent trauma victims will be set up in 3 French cities for a period of 2 years. Eligible subjects will be included in the month following PTE and will be followed longitudinally for 12 months. Evaluations at 1, 3, 6 and 12 months will be performed, during which the subject will complete various clinical and cognitive tests. A blood sample will be collected at each visit to study biological processes including the regulation of genetic and epigenetic expression, in particular the expression of the GPR56 and ELK1 genes in the blood. For eligible subjects a brain MRI will be proposed at the first visit. We hypothesize that the genetic expression of ELK1 and GPR56 is predictive of the development of psychiatric pathologies at 6 and 12 months post-PTE. The ambition of this project is also to highlight the importance of a multimodal approach integrating a triad of markers (behavioral, biological and neuroimaging) to test this hypothesis.

The goal of this clinical trial is to assess whether the presence of a certified therapy dog during dental procedures that require an injection reduces anxiety and improves behavior in pediatric dental patients. The main questions it aims to answer are: Does the presence of a certified therapy dog during dental procedure requiring an injection reduce anxiety and improve behavior in pediatric dental patients? How do the parents of pediatric dental patients who participate in the study view the use of a certified therapy dog in their child's treatment? Does the presence of a certified therapy dog result in different concentrations of microbes in the treatment room? All participants will receive standard of care. Researchers will compare the group with a therapy dog present to a group who does not have a therapy dog present to see if heart rate, oxygen saturation, percentage of nitrous oxide administered, and Frankl scores differ between the groups.

This is a prevention intervention study that will examine the efficacy of a smartphone-based intervention in decreasing cancer risk by targeting mental health risk factors of anxiety and depression.

Obsessive-compulsive disorder (OCD) and anxiety disorders are common and debilitating conditions which are often chronic when treatment is not provided. International guidelines recommend cognitive behavioral therapy (CBT) as the first-line treatment, and research has shown that CBT can be delivered over a concentrated period of time. The Bergen 4-Day Treatment (B4DT) is an exposure-based treatment which is delivered over four consecutive days. B4DT has been shown to induce rapid and long-lasting remission in around 70% of patients. This provides a platform for studying psychological and neurobiological changes associated with treatment response and non-response. The present study will investigate longitudinal changes in psychological measures and DNA methylation in patients who receive the B4DT, as well as a subset will also undergo multimodal brain imaging.

The perioperative setting is a common site of pediatric anxiety and distress. Perioperative anxiety in pediatric patients can result in uncooperative behavior, poor postoperative outcomes, and trauma. Given the fast-paced nature of the perioperative environment, many anxiety measures are too time consuming for clinical implementation prior to surgery. Pediatric anesthesiologists need reliable and efficient assessment tools to quickly measure childhood distress to target prophylactic and therapeutic interventions.

This study is intended to help develop new MRI imaging techniques for studying mood and anxiety disorders. Researchers believe that depression and anxiety disorders may cause structural and functional changes in the brain. This study will optimize the way MRI scans are collected to look at brain structure and examine how the brain behaves while subjects perform particular tasks. Healthy normal subjects between 18 and 50 years of age who have never had a major psychiatric disorder and who have no first-degree relatives with mood disorders may be eligible for this study. Candidates are screened by phone with questions about their psychiatric and medical history, current emotional state and sleep pattern, and family history of psychiatric disorders. Candidates who pass the preliminary screening then undergo additional screening interviews and laboratory tests. Participants undergo magnetic resonance imaging (MRI) and neuropsychological testing, as follows: "<TAB>MRI scans: Subjects are asked to participate in an MRI study on one of several scanners to measure blood flow in the brain, concentrations of certain chemicals in the brain, or magnetic properties of the brain. MRI uses a strong magnet and radio waves to obtain pictures of the brain. The subject lies still on a narrow bed with a metal coil close to the head. For this study, subjects may be asked to wear a special coil on the neck to help measure blood flow. They may be asked to watch a screen presenting images or to do a task in which they respond to pictures or sounds and may be asked to return for additional scans. "<TAB>Neuropsychological testing: Subjects may undergo tests of cognitive performance. Often, people with mood disorders have subtle changes in performance on these tests that allow researchers to pinpoint where brain abnormalities occur. Before the tests can be used in patients, they must be validated by using healthy subjects. These tests are presented either orally, in written form, or on a computer.

Except for exaggerated situations in which aspiration risk seems obvious (or absent), the choice of a rapid sequence induction protocol for general anesthesia is often made under uncertainty, according to the individual assessment of the balance between the aspiration risk on one hand and the anaphylaxis risk induced by short-acting curares on the other hand. The impact of anxiety and impulsivity on the choice of induction protocols under uncertainty has never been studied before. In order to investigate this issue, an online anonymous survey has been designed and will be sent to the anesthesiologists of the Bourgogne Franche-Comté and Grand Est regions in France. The primary objective of this study is to assess the impact of trait-anxiety using the STAI-Y2 form on the decision-making process of anesthesiologists during the choice of an induction protocol for patients at risk of aspiration. The secondary objectives are to characterize decision-making profiles, to measure the implicit dimension of anxiety using an Implicit association test, to study the impact of impulsivity on decision-making processes under uncertainty using the short version of UPPS-P scale and to study the role of socio-demographic data and professional history in these decisions.

The goal of this observational study is to learn more about the relation between anxiety (assessed by GAD-7 questionnaire) and the nausea and vomiting in pregnancy (objectively measured by PUQE score). Participants will answer 2 questionnaires: (GAD-7) for anxiety; and (PUQE score) for nausea and vomiting.

The purpose of this protocol is to allow for the careful screening of patients and healthy volunteers for participation in research protocols in the Experimental Therapeutics and Pathophysiology Lab (ETPB) at the National Institute of Mental Health (NIMH) and for the collection of natural history data. In addition the protocol will allow clinicians to gain more experience in the use of a variety of polysomnographic and high-density EEG recordings. Subjects in this protocol will undergo an evaluation which may include: a psychiatric interview; a diagnostic interview; rating scales; a medical history; a physical exam; brain magnetic resonance imaging (MRI); electroencephalography (EEG); electrocardiography (EKG), magnetoencephalography (MEG); blood, saliva and urine laboratory evaluation; and a request for medical records. Subjects may also be asked to complete questionnaires about attitudes towards research and motivation for research participation. The data collected may also be linked with data from other mood and anxiety disorder protocols (e.g., brain imaging, DNA, psychophysiology tests, treatment studies, etc) for the purposes of better understanding the diagnosis, pathophysiology, and treatment response of patients with mood disorders. Parents of minors will be interviewed. Upon conclusion of the screening process, subjects will either be offered participation in a research protocol and will sign the appropriate informed consent, or will be considered not appropriate for participation in research and will be referred back into the community. The current protocol thus serves as an entry point for individuals with mood or anxiety disorders or healthy volunteers to enter NIMH IRB approved ETPB protocols....

Suicide is a major public health problem. About 9,000 suicides per year are retrieved by year in France. Between 15,000 and 20,0000 suicide attempts give rise to contact with the healthcare system. Among young people aged 15 to 24 years old, suicide is the second main cause of death. In this way, suicide among adolescents is a major public health priority, due to its seriousness, its frequency, and its potentially preventable nature. The severity of suicide risk can be assessed by different scales, and the Columbia-Suicide Severity Rating Scale (C-SSRS) is the most widely used in the international literature for adolescents, assessing four dimensions: suicidal ideation, severity of ideation, suicidal behavior and lethality. The measurement of the seriousness of the suicide risk is therefore defined as the measurement of the importance of the direct and indirect negative consequences associated with this risk. It can be catch up in the four factors mentioned above. Anxiety is one of the central pillars influencing the suicidal risk of adolescents. Very few studies have identified operationalizable and generalizable risk factors for anxiety. However, in adolescents, one of the risk factors for anxiety seems particularly important, because it is a factor that is both generic (i.e., it can be found in different profiles of adolescents), related to the projection in the future (which characterizes this population), and relatively specific to this age group, while being operational through validated questionnaires. This important risk factor is the eco-anxiety, which corresponds to anxiety related to climate change. The theme of climate change is certainly a central social issue, but also an important public health issue. First, climate change raises direct risks to human health, and indirectly some risks for mental health. For instance, the direct consequences of a drought or natural disaster can cause material hardship that impacts indirectly mental health (Thoma et al., 2021). Secondly, climate change can also raise direct risk for mental health, and especially the eco-anxiety which is not the consequence of a direct risk from the environment on an individual, but rather constitutes mental distress related to the fear of such changes. Eco-anxiety can be identified and measured in a valid and reliable way thanks to a scale used in the international literature, the "Climate Anxiety Scale" (CAS), which was validated in 2020 with 22 items with 4 factors by Clayton and Karazsia (Clayton and Karazsia, 2020), and translated and validated in French in 2022 by Mouguiama-Daouda (Mouguiama-Daouda et al., 2022), retaining as the most appropriate model the version with the first 13 items. This scale is suitable for adolescents from the age of 12 years old. This 13-item scale is composed of two subscales that assess cognitive and emotional difficulties in response to climate change and functional impairment. Two subscales are added to this 13-item scale (and thus are part of the 22-item CAS also validated), which assess 1) direct or indirect personal experience of climate change, and 2) behavioral commitment and the tendency to deploy adaptive behavioral responses to climate change. The literature reports a correlation between eco-anxiety and depression (Mouguiama-Daouda et al., 2022). Indeed, depressive symptoms can influence how people worry about climate change. The correlation between eco-anxiety and anxiety is variable in the literature and has been studied using questionnaires focusing on generalized anxiety (Mouguiama-Daouda et al., 2022). Higher suicide rates have certainly been shown in populations affected by climate change (Dumont et al., 2020), related to the direct consequences of climate change, e.g., due to pollution, increased temperature or drought. However, to the knowledge of the investigators and despite the major public health impact in adolescents, no study has investigated the relationships between eco-anxiety and the severity of suicide risk. This study therefore seeks to examine the association between eco-anxiety in adolescents, assessed using the French version of the CAS, and the severity of suicide risk, assessed using the French version of the C-SSRS. We hypothesize that there would be a relationship between eco-anxiety and the severity of suicide risk in adolescents. Such results would allow both to refine the understanding of the risk of suicide, in its relationship with a central theme of society and public health, and to better identify and prevent behaviors at risk of suicide among adolescents.
