Filter by: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).
The aim of the study is to determine the influence of supplementation of probiotic Lactobacillus Plantarum 299V vs. placebo of probiotic during antidepressant monotherapy with SSRI (Selective Serotonin Reuptake Inhibitor) in patients with major depression.
The Indian Ayurvedic herb Brahmi (Bacopa monniera) has been used to improve cognitive functions in Indian sub-continent for many years and previous intervention studies have shown positive effects of Brahmi on cognitive performance in adults. However, the studies are conducted on various fractions and extracts and there is high likelihood of variability of composition amongst the fractions/extracts tested in these studies. Furthermore, although the findings of the previous studies overlap to some extent, they are not consistent and there is a need to replicate these findings. Further, even though Brahmi has been studied for its chemical composition and its therapeutic benefits as a whole, there are still severe gaps with respect to the complete composition of the Brahmi plant or its extracts. No published data exist on the Pharmacokinetics (PK) properties of Brahmi components. Hitherto, the evidence and the mechanistic details are still speculative and the biological activity is still phenomenological. Because of this severe knowledge gap, this study will try to repeat the findings on cognitive performance and at the same time also explore the plasma levels of its components in order to initiate the understanding of ADME aspects and its linkages to the biological effect.
Attention biases in threat processing have been assigned a prominent role in the etiology and maintenance of anxiety disorders. Attention Bias Modification Treatment (ABMT) utilizes computer-based protocols to implicitly modify biased attentional patterns in anxious patients. This is a double-blind randomized controlled trial of ABMT for clinically anxious 10-18 year-olds. Participants will be assessed using clinical interviews and parent- and self-rated questionnaires before, in the middle and after twelve sessions of ABMT or control groups, and again at ten-week follow-up. Outcome measures will be anxiety symptoms and depression as measured by gold standard questionnaires as well as structured clinical interviews with youth and their parents. Attentional threat bias, Attentional control and interpretation of ambiguous information will also be measured to explore potential mediators of ABMT's effect on anxiety. The investigators expect the findings to inform pathways to treatments for anxious children and to provide initial information on mechanisms of ABMT efficacy.
This is a randomized clinical trial that aims to investigate the effect of therapeutic listening anxiety and preoperative fear of patients hospitalized for surgical treatment of colorectal cancer. Physiological variables will be evaluated (heart rate, blood pressure and respiratory rate), cortisol and salivary amylase and anxiety scores by State-Trait Anxiety Inventory and fear for Surgery Fear Questionnaire. The data of the variables will be compared at two different times (before and after the intervention).
Symptoms of anxiety and depression are common in adolescents and young adults with chronic illnesses and are associated with decreased adherence to medical regimens. However, many young patients go untreated for anxiety and depression. The purpose of this study is to evaluate an online cognitive behavioral therapy (CBT) program in young adults with chronic illness. Prior research has shown online CBT to be effective in multiple other populations, but to the investigators' knowledge, this is the first study to examine web-based CBT for young adults with chronic illnesses.
This research is designed to determine the effectiveness of attention bias modification for socially anxious children and adolescents. Over the course of 3 years, 50 youth will be enrolled in the trial.
This trial examines the effectiveness of training pediatric primary care providers (nurse practitioners, doctors) to use of strategies that enhance family/youth empowerment and engagement during office visits for children with mild to moderate problems with anxiety. Children coming for routine care at one clinic are screened for anxiety symptoms and seen by either a specially trained provider or one of the clinic's other regular staff members.
The present study aims to test the implementation and sustainability of (a) a Computer-Assisted Cognitive-Behavioral Treatment (CACBT) for youth anxiety and (b) the BASC-2 TRS to identify anxious youth in the school setting using a cohort-sequential design (i.e., three years at 20 schools over the span of five years). 'Camp Cope-A-Lot (Computer-assisted CBT program)'
A single blinded controlled trial to determine if an intervention of listening to nursery songs with integrated heart beat sounds results in changes in anxiety level in infants and young children less than four years of age in an emergent setting.
