Active clinical trials for "Anxiety Disorders"

A randomized, blinded, placebo-controlled, direct-to-consumer study assessing the impact of health and wellness products on feelings of anxiety, stress and other health outcomes

The prevalence estimates for specific mental disorders and illicit drugs have been separately reported in U.S. government surveys. Less is known about the rates for specific comorbid conditions, e.g., schizophrenia and substance abuse, major depression and substance abuse, bipolar disorder and substance abuse, and anxiety disorder and substance abuse. The effects that different demographic characteristics (ethnic background, family medical history, age, living conditions [e.g., living with a single parent]) have on the prevalence of comorbid mental illness and substance abuse also have not been considered. More should be known about the duration of substance abuse in different mental illnesses among those undergoing treatment, and whether specific types of drugs are associated with specific mental illnesses. In this study, Advanced Clinical Laboratory Solutions, Inc. will investigate the prevalence rates for the specific comorbid conditions and demographic relationships described above. This multi-site, proof-of-concept cohort study will analyze urine or oral fluid samples from 1,000 subjects diagnosed with one of four mental illnesses (schizophrenia, major depression, bipolar disorder, or anxiety disorder) as determined by DSM-IV (The Fourth Edition of the Diagnostic and Statistical Manual of Mental Disorders). The samples will be analyzed for both prescription drug compliance and illicit substance abuse. Urine or oral fluid samples will be collected at three time points: 1) immediately after enrollment and obtaining informed consent, 2) randomly within 2 to 4 months of the study, and 3) at the end of the study (6 months).

Inflammatory Bowel Diseases (IBD) are life-long, incurable illnesses that can have a profound effect on the patients quality of life. Disease education is a corner stone of IBD care to enable patients to take up an active role in their disease management. While patient education is enshrined in the IBD standards, actual patient knowledge is often poor.3 Knowledge is not associated with the level of the patient's educational achievement, but member of patient organisations such as Crohn's and Colitis UK (CCUK) have significantly better knowledge than non-members. This may highlight the positive effects of education offered by CCUK, but it is also conceivable that patients with a greater interest in their disease are more like to join organisations like CCUK. Different sources of patient information may therefore influence what level of disease related knowledge a patient achieves. Apart from high quality clinical information provided by professional organisation (British Society of Gastroenterology, European Crohn's and Colitis Organisation), the National Health Service and charities (CORE, CCUK), there is also a host of unregulated information available. The emerging dominance of the internet for information gathering has provided easy access for patients to a host of websites providing information on IBD. A number of these provide alternative (not evidence based) views, which could have a potentially negative impact on patient's knowledge. Furthermore patients often share their stories on internet forums and it is likely that those stories share are more likely to represent the extreme ends of disease rather than those experienced by the majority. This could potentially cause anxiety in patients with IBD. The quality of information found on the internet varies widely and up to 50% of websites have been judged as poor. The vast majority of patients with IBD have access to the internet and more than half use to search for health related information.7 We have previously also demonstrated that patients with anxiety have better disease related knowledge of IBD.

Colonoscopy is an outpatient procedure performed frequently as a screening test for diagnosis and treatment of a wide range of gastrointestinal problems. It is often viewed as an invasive procedure with the potential for embarrassment, discomfort, and worry. Such fears can result in anxiety that may decrease the tolerance and cooperation of the patient, limit the success of the procedure, and increase the likelihood of complications. Therefore, colonoscopy is frequently performed under sedation. The anxiety level of the patient before the procedure may increase the requirement for sedation. It is important for the anesthesiologist to predict the effective dosages of sedation before the procedure to ensure rapid and comfortable sedation as well as prompt recovery and discharge of the patient. This prospective cohort study is planned to evaluate the effects of pre-procedural anxiety level on the dose of propofol needed for patient and surgeon satisfaction during colonoscopy.

This study will identify variations in genes that may be involved in the development of suicidal events or certain behaviors in youth who are exposed to antidepressant medications.

This study will look at similarities and differences in family processes and child temperament among children with and without symptoms of anxiety disorders.

Mothers usually have the primary role in bringing up children and developing health-related behaviors. The aim of this study was to determine the effect of mothers' dental anxiety and oral hygiene on the dental anxiety and periodontal health of their children. The study included 280 randomly selected children, aged 4-12 years, who came to the dentist for the first time and their mothers. Demographic and oral hygiene information of the mothers was collected through a questionaire. Dental anxiety of the mothers and children was assessed using the Modified Dental Anxiety Scale (MDAS) and the Venham Picture Test (VPT), respectively.

The study was conducted among a group of dental patients aged (6-8 years old) of both genders to assess the following variables in the needleless interparliamentary anesthesia (NUMBEE) compared to traditional local anesthesia: Pain perception. Pain related behaviors. Dental anxiety Anesthetic efficiency. Patient acceptance and preference

We elected to establish a pilot near-peer coaching program for URM students enrolled at the Medical College of Wisconsin MCAT program. We quantified baseline and specific time point test-anxieties using the validated Westside test anxiety scale. We asked about MCAT concerns and program impressions via a free response section and analyzed results with inductive analysis.

Background: Research has shown that anxiety affects more than feelings. It also affects behavior. Researchers want to learn how the brain and body respond to unexpected threats. They want to see if probable pleasant or unpleasant events change decisions. Objective: To better understand how changes in anxiety are associated with changes in decision-making. Eligibility: Adults aged 18-50 with generalized anxiety disorder, seasonal affective disorder, or panic disorder. Healthy volunteers are also needed. Design: Participants will be screened under protocol #01-M-0254. Participants will complete surveys about their anxiety, risk-taking, and curiosity. Participants will complete a computer task. They will be given different choices. They will make a choice. They will receive an unpleasant or pleasant stimulus based on their choice. They will repeat this task many times. Most participants will do the task in the clinic. The unpleasant stimulus will be electric shock and acoustic startle. They will receive electric shocks through electrodes placed on their arm or fingers. They may hear loud noises through headphones. Their eyeblinks will be recorded with electrodes placed under their eye. Their heart rate and skin conductance activity will be collected with electrodes as well. Some healthy volunteers will do the task during a functional magnetic resonance imaging scan. They will lie on a table that slides in and out of a scanner. A coil will be placed over their head. The unpleasant stimulus will be electric shock, given as stated above. The scanner will record their brain activity. Their breathing and pulse rate will be recorded as well. Participation will last for 3-4 hours.
