Filter by:This research study will evaluate a standalone software application and is designed to standardize and validate new neurocognitive screening testing for children aged 6 through 11, and adolescents and adults ages 12 through 75. The purpose of this study is to evaluate recently developed computerized tasks sensitive to changes in neurocognitive performance after a concussion. These tests were designed to help measure the effects of concussion on cognitive processes (e.g., memory, attention, brain speed) and visual functioning.
Individuals aged 55 and older may experience negative effects of cognitive decline. The proposed research seeks to evaluate the benefits of different types of interventions: reasoning training following transcranial direct current stimulation (tDCS) and reasoning training following sham transcranial direct current stimulation (tDCS) on frontal- lobe mediated cognitive measures of executive control in adults with memory complaints, in the absence of dementia.
This study is designed to test if megestrol acetate induces changes in declarative memory in healthy controls and if pre-administration of phenytoin can ameliorate any induced cognitive impairments.
Background: Mild Cognitive Impairment (MCI) is a risk factor for dementia and represents a critical window of opportunity to intervene and alter the trajectory of both cognitive and functional decline. Emerging life-logging technologies has shown a tremendous potential to increase autobiographical memory. Objective: The main goal of the present study is to develop a Cognitive Training program (CT) for MCI based on life-logging captured by a Wearable Camera (WeC) recording specific autobiographical episodes for stimulating posteriorly episodic memory. The challenge is to create an application to manage this large collection of images, which can be easily retrieved as events by users in a therapeutic context as a multimodal cognitive stimulation. The investigators will conduct a quasi-experimental design with non-equivalent control group, evaluating the effectiveness of the life-logging re-experiencing program immediately and 3-month follow-up period. Methodology: The design is a pretest, posttest and follow-up design, where 30 adults with MCI were sequentially allocated to one of two conditions: intervention or control group. All subjects wore a lifelogging WeC during two weeks, and subsequently they were generated several videos with the most relevant information of each event. Subjects in the Intervention Group will attend 1-hour individual training sessions 2 times per week for 14 8 weeks. Main outcomes measures will be cognitive, functional, emotional and quality of life measures, as well as biochemical measures (BDNF). Expected results: The investigators expect the outcomes to provide preliminary evidence that autobiographical experimentation CT programs can positively impact cognitive functioning and may represent an effective strategy to improve memory and functionality in those who begun to experience cognitive decline.
This study addresses an important public health concern; impoverished cognitive function associated with treatment of breast cancer. Due to increased awareness of breast cancer combined with advances in medical care, there are over 2.8 million women living with a history of breast cancer in the U.S. alone. Chemotherapy and adjuvant therapy to remove cancerous tissue can result in deficits in attention, speed of processing, memory, and quality of life. Physical activity has been associated with a number of health benefits for breast cancer survivors including improvements in cognitive function. However, most of the literature is cross-sectional and it is unclear whether acute (single) bouts of physical activity affect cognition and, if they do, how long this effect lasts. This study will be the first, to the investigators' knowledge, to examine the effects of an acute bout of aerobic exercise on cognitive functioning in breast cancer survivors. Specifically, the investigators will determine the effects of a 30-minute moderate intensity aerobic exercise session (treadmill walking) on immediate and one hour follow up changes in measures of processing speed, memory, and executive function. Additionally, accelerometer cut-points for physical activity intensities in breast cancer survivors will be assessed. Finally, the investigators will examine the association of cardiorespiratory fitness and physical activity with changes in cognitive function. Findings from this study will allow researchers to determine whether any acute effects of exercise on cognition are retained over time and therefore have real meaning in the context of one's daily life.
The purpose of this study is to determine whether Cymbalta (duloxetine) is effective to improve cognition in individuals with Mild Cognitive Impairment.
In the study, NextGen SE are on-hand a cohort comprising each 50 pediatric and 50 adult patients, and in which there are an unclear movement disorder or an unclear cognitive disorder, examines the following questions : Primary: - Number of diagnoses made by NGS Secondary: 1. restriction of the quality of life by unclear disease 2. Cost of not purposeful preliminary diagnostics ( beyond the minimal diagnostic data set ) 3. Impact of the diagnosis to therapy and follow-up examinations 4. Time to diagnosis
This study will provide cognitive screenings for seniors age 50 and older. It will also investigate the benefits of two different cognitive training programs for seniors who have lower baseline performance on memory and/or gist reasoning tests.
This study investigates the beneficial effects of prefrontal brain stimulation (with transcranial direct current stimulation [tDCS]) during working memory training in seniors with subjective memory impairments.The placebo-controlled double blinded study includes 50 elderly probands which were randomized into verum or sham tDCS.
The goal of this research study is to test the feasibility of an intervention programme to reduce cognitive impairment due to cancer treatment. The investigators want to find out how acceptable the intervention and procedures are for cancer patients.
