Filter by:This trial aims to Study the efficacy of DBT skills for impulsive aggression and executive dysfunctions in drug naïve children who are presented with impulsive aggression and ADHD and attending Child and adolescent clinic at Alexandria university hospitals using weekly group therapy for 8 month and testing pre and posttreatment biomarkers of aggression.
This project explores the association between learning and cognitive flexibility by testing whether a cognitive behavioral intervention designed to improve flexibility in ASD changes learning and associated neural activation using model-based functional magnetic resonance imaging (m-fMRI). The study proposes that variability in learning mechanisms is associated with behavioral flexibility and explains differences in adaptive and treatment outcomes. The study employs a longitudinal case-controlled design in 60 14-18 year old youth with ASD at 3 time-points 8 months apart, each including m-fMRI during learning and behavioral measurement of executive and adaptive function. Aim 1 tests the hypothesis that individual variation in learning biases and their neural correlates predicts behavioral flexibility and is stable over time. Aim 2 tests plasticity of learning mechanisms induced by a cognitive-behavioral intervention for flexibility. Aim 3 tests hypothesis about intervention-induced plasticity of neural functional connectivity.
The aim of this project is to elucidate whether impairments of cognitive control, performance-monitoring, and value-based decision-making and dysfunctional interactions between underlying brain systems are mediating mechanisms and vulnerability factors for daily self-control failures and addictive disorders.
In this project, the investigators will extend prior results of parent-reported executive function growth and symptom reduction in children receiving home-based treatment with the Collaborative Problem Solving treatment approach (CPS), with a particular focus on examining children who have attention deficit hyperactivity disorder (ADHD). The investigators will examine executive functioning (EF) of children who are receiving CPS, measuring EF with parent-report and objective computer-based tasks, at two timepoints: at the start of treatment and approximately four months later, and will collect symptoms at these plus three additional timepoints: at discharge, 6-months after discharge, and 12-months after discharge.
Main objective: to evaluate the executive functioning of the HIV exposed uninfected children (HEU) versus children from the same socio-economic and cultural environment, not infected or affected by HIV. Secondary objective (s): to evaluate Intellectual Quotient, Child development, Behavior, Language and investigate link between executive functioning disorders, exposure to ARVs, HIV and family environment.
Brief Overview: Children and adolescents diagnosed with cancer will experience problems with learning, memory and attention during and after completing their cancer therapy. There are many factors that contribute to this problem, but investigators have recently identified that chemotherapy agents used in treating Acute Lymphoblastic Leukemia (ALL) may disrupt normal brain development. A novel device has been developed that may help correct this disruption. Direct Current Stimulation (DCS) uses a very low level of constant electrical current to stimulate specific parts of the brain. It has been used in patients with stroke to great benefit. Our study at St. Jude Children's Research Hospital is designed to see if this technique will benefit survivors of childhood cancer. Specifically, investigators wish to see if stimulating one part of the brain gives a greater benefit than stimulating another part of the brain. Primary Objective Evaluate the feasibility of conducting repeated on-site Transcranial Direct Current Stimulation (tDCS) in children who are long-term survivors of Secondary Objectives - To estimate the potential efficacy for powering a future larger study using tDCS to improve cognitive performance in children by suppressing over connected neural hubs in long-term survivors of childhood ALL. - To compare the performance of anodal stimulation of the frontal lobe to cathodal suppression of the superior temporal lobe on cognitive performance.
Explanation of the study: As the older adult population continues to rise, so will normal cognitive aging. This increase raises concern for maintaining cognitive function and possibly delaying the onset of disorders such as dementia. Cognitive training (CT) is one potential solution which may be done using computer programs, pencil-and-paper problem solving activities, or everyday tasks. Traditional, skilled occupational therapy (OT) is not reimbursed for this type of preventative or maintenance services. CT may be a fundable answer for older adults to maintain or even improve cognitive function. The purpose is to determine if computerized CT, utilizing a specific program (RehaCom), improves executive functioning in the older adult with mild cognitive impairment, as compared to pencil-and-paper CT. How study is performed: Participants who meet the inclusion criteria will complete a 9-question demographic survey and pre-test standardized cognitive tests. The experimental group will complete RehaCom computer training and the control group will complete paper-and-pencil based training. All trainings will take place at Mercy LIFE and will be conducted by trained OT students. Subjects will complete a total of 480 minutes of training over a 12-week period, within 30 to 60 minutes sessions. After the 480 minutes of training, subjects will complete the cognitive post-tests. How data is collected, de-identified and analyzed: Participants who enroll will be assigned a code number linked to their first and last name. This coding will de-identify participants before analyzing or reporting. All signed forms, data collected, and data identified will be kept in a locked cabinet in the researcher's office. All stored files will be shredded one year after the study. Interventions/tests/medications: Computerized CT: RehaCom is a computer program that was designed to assist cognitive rehabilitation. The program targets attention, concentration, memory, perception, and problem-solving, with trainings lasting for a total of 480 minutes over 12 weeks. Pencil-and-paper CT: Various pencil-and-paper exercises to improve attention, concentration, memory, language, and orientation will be used. Such exercises may include word puzzles, calculation or number puzzles, and map reading, for a total of 480 minutes of training over 12 weeks. Potential risks: Risks of feeling segregated are minimal, as all members have been offered the opportunity to use the site's computer room. Risks may include cognitive fatigue (in both groups) or overstimulation during computer use. Breaks will be given at any sign of these symptoms. There is a small possibility that the participant may become too overwhelmed or stressed with the cognitive training. Upon notice of these symptoms, activities will cease immediately. Potential and expected benefits: Participants may gain a greater insight into cognitive abilities and improvement of executive functioning skills. Increased knowledge on effects of using cognitive software in a community-based setting may also occur. Mercy LIFE will receive the benefit of continued use of the RehaCom software and laptop as the equipment will be left at the site. Additionally, these findings may help other community-based sites incorporate specific cognitive training for other older adults.
Brain scans can help identify changes that appear to increase risk for cognitive decline and dementia. Some of these brain changes are thought to reflect actual damage to the small blood vessels that support normal brain function. This clinical trial will determine whether an omega 3 polyunsaturated fatty acid (PUFA) therapy can promote brain health by supporting the small blood vessels in the brain over 3 years in older adults at high risk for cognitive decline and dementia of Alzheimer's type.
