17 Clinical Trials for Various Conditions
Adaptive reasoning and problem-solving are critical skills that allow for accurate decisions to be made based on varying levels of information. In many situations these decisions must be made and communicated under stressful, time-sensitive conditions. In such contexts, an ability to apply inductive and deductive reasoning to complex, ambiguous, and/or novel problems is critical. The objective of the INSIGHT project is to establish a comprehensive and rigorous brain training protocol to significantly improve adaptive reasoning and problem solving. We will examine a variety of interventions (cognitive training, physical fitness training, physiological stimulation, , and combinations thereof) to assess their ability to improve adaptive reasoning and problem solving abilities. Multimodal interventions are hypothesized to act synergistically to significantly enhance fluid intelligence (Gf) and underlying brain structure and function.
The aim of this study is to investigate the acute effects of ingestion of carbohydrates - with different glycemic profiles - on cognitive function among preadolescent children (i.e., 9-10 years).
The objective of this study is to use a randomized controlled design to determine whether cardiorespiratory fitness training improves neurocognitive function and academic performance during preadolescent development.
Exercise has been linked to cognitive health, but few older adults exercise at recommended levels. Cybercycling may provide additional cognitive benefits due to increased motivation to ride the interactive 3D tours. Participants will be randomly assigned to three months of either cybercycling or traditional stationary biking; and they will complete comprehensive evaluations before and after exercise. Older adults are expected to show significant neuropsychological, physiological and behavioral gains.
This study aims to examine the benefits to thinking processes of a low intensity, strengthening exercise program for older adults.
The goal of this study is to evaluate the effects of beef consumption on cognitive and brain health in healthy young adults. Specifically, we seek to evaluate the effects of beef consumption on measures of executive function, memory, psychological well-being, and sleep quality. Additionally, we will explore the effects of increased beef consumption on measures of brain health derived from structural and functional brain imaging. All participants will take part in a 12-week dietary intervention study. Throughout the intervention, participants will receive 5 portions of ready-to-eat beef in frozen packages each week. Each serving of ready-to-eat beef for the experimental group will weigh 5-ounces, while each serving of ready-to-eat beef for the comparison group will weigh 1-ounce. Study compliance will be evaluated through weekly surveys about beef consumption. In addition to completing the dietary intervention, participants will complete pre- and post-intervention assessments: * MRI scan, including structural and functional brain imaging * a comprehensive questionnaire battery evaluating cognitive and psychological measures * neuropsychological tasks * a blood draw
The purpose of this study is to examine the effects of modifiable lifestyle factors including exercise and healthy living on brain health. The investigators will compare 2 types of interventions, moderate aerobic walking vs. healthy living education, over 6 months to evaluate changes in brain health, cognition, and physical function in older adults with cognitive concerns.
The investigators propose to conduct a single-blind randomized clinical trial to test the efficacy of a computerized cognitive remediation intervention program on improving locomotion in sedentary seniors, a group at an especially high risk for disability. The hypothesis is that executive functions will respond to the cognitive remediation program and in turn enhance locomotion.
Since droxidopa has been approved in Japan for treating freezing of gait in Parkinson's disease patients, this is to confirm and further investigate the safety and efficacy using a similar dose. The possible beneficial effects on cognition in mildly cognitively impaired Parkinson's disease patients will also be tested, since this problem in Parkinson's disease may be associated with decreased brain synthesis of norepinephrine (a neurotransmitter associated with multiple brain functions). During this 11 week study, droxidopa will be slowly titrated up to 600 mg daily. Walking and freezing of gait will be evaluated and rated. Cognitive functions will be evaluated by a computer-based program.
RATIONALE: Radiation therapy uses high-energy x rays to kill tumor cells. Radiation therapy may cause skin reactions when patients are exposed to high-energy x rays. Studying the genetic pattern of patients before and after radiation therapy may help doctors prevent toxicity and plan the best treatment. PURPOSE: This clinical trial studies genetic susceptibility to radiation-induced skin reactions in racial/ethnic groups of patients with breast cancer.
The purpose of this study is to determine whether pediatric anesthesia is associated with long-term hippocampal dysfunction
This study is designed to assess the best method for caring for elders reported to Adult Protective Services (APS) for self-neglect. Specifically, this study will compare APS usual care coupled with interdisciplinary comprehensive geriatric care to APS usual care alone in improving the health and quality of live among elders with substantiated self-neglect.
The purpose of this study is to see if treatment with Ginkgo improves cognitive function in people with multiple sclerosis who have cognitive problems.
The purpose of this study is to examine the effect of aerobic fitness training on human cognition, brain structure, and brain function of older adults.
In this study the investigators will interrogate an existing data set to examine whether genetic variants contribute to an inverse association between weight status and cognitive function. Investigators hypothesize that body mass index (BMI) will be inversely related to a number of variables measuring cognitive function, and that that this inverse relation will be at least partially attributable to genetic variants which influence both BMI and cognition.
The goal of this basic experimental clinical trial is to understand the effect of multitasking practice on the structure of neural representations of tasks in the human lateral prefrontal cortex and control brain regions. The main question it aims to answer is: What changes in neural representational structure predict improvements in multitasking behavior due to multitasking practice? Healthy human participants will learn two independent tasks, each mapping a set of stimuli to motor responses based on different rules. Participants will be randomized to one of two interventions. Participants assigned to the multitask practice intervention (MPI) will practice multitasking the two tasks over multiple days. Those assigned to the single-task practice intervention (SPI) will instead practice each task separately while controlling for the total number of practice opportunities associated with each task across the interventions. Both before and after the practice, the ability of all participants to perform both tasks simultaneously will be behaviorally measured using a well-established psychological refractory period (PRP) paradigm, and their neural representations will be measured using functional MRI while they perform the two tasks. Researchers will then compare improvements in multitasking behavior across the two groups, as well as changes in neural representational geometry of the tasks in the lateral prefrontal cortex and control brain regions, and test whether multitasking training is associated with specific changes in neural representations in the lateral prefrontal cortex.
The purpose of this study is to investigate neurocognitive mechanisms underlying response to intervention aimed at enhancing, and remediating weaknesses in, numerical skills in children, including those with mathematical learning disabilities (MLD).
