Filter by:This study will evaluate the ability of sounds played during slow wave sleep using a phase locked loop algorithm to enhance slow wave sleep and memory in cognitively healthy older adults and in those with amnestic mild cognitive impairment.
This protocol describes a study to validate Neurotrack's visual paired comparison task, aimed at early detection and monitoring of memory impairment. The investigators will determine whether the novel task developed by Neurotrack is associated with markers of brain pathology associated with very early Alzheimer's disease. The elderly subjects studied will be cognitively normal (CN) or have amnestic mild cognitive impairment (aMCI). For the current study, the primary brain pathology parameters will be derived from MRI scans. Data from this study will be correlated with data from a parallel study designed to validate a larger group of new cognitive tasks by correlating test performance with a broader array of biomarkers of Alzheimer's disease.
The project is designed to generate critical information to design and justify a robust trial on lithium prevention of the onset of Alzheimer's disease (AD). Lithium exerts and inhibitory effect on Glycogen synthase kinase 3 (GSK-3) a brain biomarker of neuroprotection. The study consists of 3 phases: 1. Phase 1 investigates rats to establish a reliable method to measure brain biomarker activity levels from blood biomarker activity. 2. Phase 2 will determine whether the GSK3 enzyme activity is significantly different in subjects with MCI compared to normal individuals. 3. Phase 3 investigates patients with MCI taking lithium to establish the minimum lithium dose required to inhibit the activity of GSK-3.
As cancer mortality rates improve in Asia, there is an increasing focus on patient-reported outcomes and survivorship issues. In view of the numerous medication and psychosocial issues that are commonly faced by early-stage breast cancer survivors, it deems important to develop and conduct specific interventional programs to mitigate these problems. In the literature, it is well recognized that psychosocial interventions are effective to manage emotional distress and quality of life, with the evidence clearly clustered in studies on female patients with breast cancer. One meta-analysis suggested that psycho-oncologic interventions including individual psychotherapy, group psychotherapy, psychoeducation, relaxing training can produce positive effects on emotional distress, anxiety and depression, and health-related QOL. The investigators hypothesize that a significant reduction in anxiety, improvement of cognition and improvement of health-related quality of life among those who receive psycho-education, in comparison to those in the usual care. Hence, this randomized trial is designed to assess the effectiveness of a psycho-educational group (PEG) intervention on supportive care and survivorship issues, which include anxiety, depression, cognitive function, toxicities management of cancer- or treatment- related physical symptoms, and health-related quality of life in early-stage breast cancer patients.
The purpose of this work is to determine whether preoperative cognitive screening of patients over the age of 65 can be used as predictor of postoperative outcomes in patients undergoing lower extremity surgical procedures. This work is important as it may aid patients, families and physicians about the appropriateness of the surgical procedure and in providing resources to patients who are at the highest risk of adverse outcomes.
Patients with cognitive impairments following a stroke are often denied access to inpatient rehabilitation, despite evidence of its benefits for them. Patients with cognitive impairment who are admitted to inpatient stroke rehabilitation often receive services based on outdated impairment-reduction models, rather than recommended function-based approaches. These two issues, reduced access to rehabilitation and the knowledge-to-practice gap, both stem from a reported lack of skills and knowledge on the part of some stroke rehabilitation teams to foster recovery in people with cognitive impairments. To address these issues, the investigators will implement and evaluate a multi-faceted, supported, integrated knowledge translation initiative, targeted specifically at the inter-professional application of the Cognitive Orientation to daily Occupational Performance (CO-OP), called CO-OP KT. CO-OP is a contemporary, effective, cognitive strategy-based treatment approach. CO-OP KT is a combination of the CO-OP Approach with multi-faceted knowledge translation support. Clinical staff at participating institutions will receive CO-OP KT training. The long-term objective of CO-OP KT is to optimize functional outcomes for individuals with stroke and cognitive impairments. Three specific research questions have been posed, one of which is the focus of this registration. That sub study relates to patient outcomes following the CO-OP KT training initiative and it will be addressed using a non-randomized design with historical controls. Patient participants who enroll in the project prior to implementing the CO-OP KT training will belong to the historical control group. Patient participants who enroll in the project after the CO-OP KT training will belong to the CO-OP KT Exposure group.
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.
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.
