Active clinical trials for "Anxiety Disorders"

In the present study, we aimed to assess children's anxiety levels by using different dental anxiety scales and children's drawings evaluated according to two different scoring systems: Child Drawing: Hospital (CD: H) and Emotional indicators of Human Figure Drawings (HFD).

Today, there are many studies on wheelchair basketball players. However, these studies do not indicate the relationship between the quality of life, life satisfaction and anxiety levels of wheelchair basketball players, in the extent of the knowledge. As a result of this study, it is aimed to obtain information about the quality of life, life satisfaction and anxiety levels of wheelchair basketball players.

The goal of this proposed study is to identify a potential biobehavioral marker of CBT outcome in the most common child and adolescent anxiety disorders, including separation anxiety disorder (SAD), social phobia (SoP), and generalized anxiety disorder (GAD), and to replicate in a clinical sample the previous finding from animal and non-clinical human samples that a difference exists in extinction learning across development.

Alcohol dependence is among the most common and costly public health problems affecting the nation. Among individuals with alcohol use disorder (AUD), those with (vs. without) a co-occurring anxiety disorder (AnxD) are as much as twice as likely to relapse in the months following AUD treatment. Dysregulation of biological stress-mood systems predict and correlate with AUD relapse and AnxD symptomatology. In contrast, stress system re-regulation correlates with improved AUD treatment outcomes but has not been examined with respect to AUD recovery and relapse in co-occurring AUD+AnxD.

In this study, investigators wanted to investigate the effect of preoperative anxiety level on anesthesia preference of patient. Before surgery, patients will fill the forms of Pain catastrophising scale (PCS), Beck depression and Beck anxiety scale. After surgery, these forms will be evaluated according to the choice of anesthesia.

Anxiety is commonly considered as an epiphenomenon of the cognitive and emotional response to a threat. Anxiety is a consequence of the reciprocal interaction between stress and the neuroendocrine, autonomic and immune systems. A systematic and circumstantial assessment of anxiety in critically ill patients has never been done. Our hypothesis is that high levels of anxiety at ICU admission are associated with death or the occurrence of one or more organ failure during the first 7 days, and that anxiety should be considered as a "warning sign" in critically ill patients.

MRI has been recognized for many years as the safest and the most precise imaging method, particularly for children. However, the accuracy of MRI demands from the patient to avoid any movement while the examination is in process. This task is accomplished with difficulty by children and requires the assistance of an anesthetizing staff. In this research, our main goal is to investigate an introductory instruction as an assistive tool in performing MRI without the need in anesthesia.

Objective: Metabotropic glutamate receptors (mGluRs) are G-protein coupled receptors that respond to glutamate by activating proteins inside nerve cells that affect cell metabolism, thereby fine-tuning the signals sent between cells to maintain balance in neuronal activity. mGluR subtype 1 (mGluR1s) are located in several brain regions, including the cerebellum, hippocampus, olfactory bulb, and basal ganglia. mGluR1 activation stimulates phospholipase C, resulting in phosphoinositide hydrolysis and increased intracellular calcium levels. Successful development of a positron emission tomography (PET) ligand to image mGlurR1 would impact clinical management of brain disorders characterized by disruptions in glutamatergic transmission, including anxiety and stress disorders, drug addiction, epilepsy, Huntington s disease, and Parkinson s disease. However, detailed study of mGluR1s has heretofore been hindered by the lack of high affinity and selective ligands for this receptor subtype. The present protocol will evaluate the ability of a new PET ligand, [18F]FIMX, to image and quantify mGluR1 in the brain of healthy human volunteers. This protocol covers four phases: Phase 0: screening whole-body scan; Phase 1: kinetic brain imaging to quantify mGluR1 in brain relative to concurrent measurement of the parent radioligand in arterial plasma; Phase 2: if the tracer is successful in Phase 1, we will estimate radiation-absorbed doses of [18F]FIMX by performing whole body imaging; Phase 3: test-retest analysis of brain binding relative to concurrent measurement of the parent radioligand in arterial plasma. Study Population: Healthy adult female and male volunteers (n=22, ages 18 to 55) will undergo brain or whole-body imaging.. Design: This study will begin with a screening whole-body scan to confirm that the radioactivity has fairly broad distribution in several organs. For absolute quantification of mGluR1, 22 healthy controls will have brain PET imaging using [18F]FIMX and an arterial line. Up to 12 of them will have a test-retest scan. Eight additional subjects will have a whole body PET scan for dosimetry, which does not require an arterial line. <TAB> Outcome Measures To assess absolute quantitation of mGluR1 with [18F]FIMX, we will primarily use two outcome measures: the identifiability and time stability of distribution volume calculated with compartmental modeling. In test-retest study, we will calculate the retest variability. To assess whole-body biodistribution and dosimetry of [18F]FIMX we will use the organ time-activity curves....

Anxiety disorders are common and impairing. Although exposure therapy is one of the most effective treatments for anxiety, some individuals do not fully respond to treatment, and these individual differences are not well understood. Exposure therapy involves repeated, deliberate, safe engagement with a feared stimulus without the feared outcome occurring. This treatment is thought to work through a type of emotional learning called fear extinction. This study aims to look at links between fear extinction learning and exposure success, with the overall goal of better understanding who is likely to respond best to exposure therapy and why.

The aim of the study is to assess the remission rates in patients treated for generalized anxiety disorder in primary and specialized care. Factors that may influence remission such as disease history and severity of the anxiety disorder, the type of treatment, the presence of co-morbid depression or anxiety disorder as well as socio-demographic factors will also be evaluated. The study will also assess patient functioning and compare functioning in patients who do and do not achieve remission.
