Filter by:This study aims to investigate and compare the intervention effects of acupressure,aromatherapy,combining acupressure and aromatherapy in elderly with mild cognitive impairment. The investigators hypothesize that (1) Combined intervention can induce greater improvements in the outcome measures than single mode of intervention; (2) the improvement in cognitive functions and other outcomes may differ between the groups.
Abstract Method: Participants with a diagnosis of stroke and have cognitive impairment (a score of 3 or more on the Executive Interview, 14-item version) will be randomly assigned to the intervention group and the attention control group at a 1:1 ratio. Each session will be around 45 minutes and will be delivered 1 to 2 sessions per week for 12 to 15 sessions. Outcome measures including the Participation Measure- 3 Domains, 4 Dimensions (PM-3D4D), Canadian Occupational Performance Measure(COPM), Activity Measure for Post-Acute Care (AMPAC) Outpatient Short Forms, Wisconsin Card Sorting Task (WCST), Stroop Test, Montreal Cognitive Assessment (MoCA), Trail-Making Test (TMT A and B), The National Institutes of Health Stroke scale (NIHSS), modified Rankin Scale (MRS), Euro-QoL-5-Dimension (EQ-5D) and Participation Strategies Self Efficacy Scale (PS-SES) will be administered at baseline (T1), post-intervention (T2), 3-month follow-up (T3), 6-month follow-up (T4), and 12-month follow-up (T5). Of the recruited participants, 50 will recieve the fMRI tests (including the resting-state scan, the fMRI scan with Stroop Test and TMT tasks, and the anatomical structure scan) at baseline, post-intervention, and 6month follow-up.Data will be analyzed using multiple linear regression models and mixed-effects regression models.
The purpose of this study is to evaluate whether a short interactive video game device is associated with performance on standard measures of attention and problem solving in patients with systemic lupus erythematosus(SLE). The study is also designed to see if playing the video game for four weeks improves attention and problem solving in patients with SLE.
Pulmonary rehabilitation program with aerobic and strengthening trainings for 3 months will be applied to the candidates for lung transplantation. The program will be designed to be 2 days supervised weekly and 3 day home program. After completion of the program, patients will be divided into two groups according to their cognitive status (Group 1: those with poor cognition; Group 2: those with good cognition). The PR gains of the groups will be compared.
WHO: 40 participants with a confirmed diagnosis of Multiple Sclerosis (MS) able to engage in moderate physical activity. WHY: The purpose of this study is to evaluate two computerized brain training tools, which include light physical activity, to see if they can help improve cognitive functions, such as memory and attention, for patients with MS. WHAT: Complete a set of tests (physical and cognitive) at baseline, wear a Fitbit Flex device at home for the duration of the study, 3 supervised sessions for 4 weeks at UCSF, one visit for physical and cognitive tests at one week after the final supervised session, and one final visit 6 months after the final supervised session. WHERE: 20 participants at the UCSF Weill Institute for Neurosciences (675 Nelson Rising Lane, San Francisco, CA); 20 participants at Lausanne University Hospital (Rue du Bugnon 46, 1005 Lausanne, Switzerland)
To evaluate the effectiveness of using clinical precision medicine to develop lifecourse interventions for Alzheimer's disease (AD) prevention and treatment. Anthropometrics, blood biomarkers (including genetics), and cognition will measured longitudinally to assess the comparative effectiveness of clinical care.
This research project will test two new computerized technologies in the detection of brain changes related to Mild Cognitive Impairment (MCI) and dementia due to Alzheimer's disease. These technologies are: 1. Computerized cognitive battery: Cognigram (CG) Computerized assessments have multiple advantages for the early detection of subtle changes in cognition in older adults. One of their main advantages is their higher precision when measuring accuracy and speed of responses, compared to pencil-and-paper tests. They also allow a greater reliability in measures, as tests are given in a standardized format without the interference of an evaluator. Finally, by including automatized instructions and reports, they are suitable for off-site or long-distance use. The present study aims to validate the Cognigram™ (CG) computerized cognitive tool, in a prospective and longitudinal fashion, determining if changes in the CG scores over 3, 6, 9, and 12 months, can predict progression to dementia at 1-year, 2-years, and 3-years, for patients with Mild Cognitive Impairment (MCI). 2. The NeuroCatch™ Platform (NCP) Event-related potentials (ERP) are non-invasive, low-cost, electrophysiological methods that allow recording of the electrical activity of the brain in vivo through an Electroencephalogram (EGG). They are free from cultural and educational influence and can provide insights into the cognitive processes. ERP could enable to detect brain changes and determine the prognosis of MCI subjects. The NCP, an investigational medical device system developed by NeuroCatch Inc., consists of an EEG software and hardware that captures brain health information. It offers a quick (i.e., 10 minutes for EEG preparation and 6 minutes for each task of EEG recording), simple (i.e., includes only 8 electrodes), and easy-to-use solution (i.e., includes a computerized software that automatically analyzes data and outputs graphs in less than 1 minute) for the acquisition of EEG and ERP.
This study aims to explore the determinants of cognitive impairment among Indonesian geriatrics in an Old Age Home.
The Etude Study is a multi-center, four-arm prospective dose-adjusting study designed to assess the tolerability, safety and efficacy of non-invasive sensory stimulation for patients with cognitive impairment.
The overarching purpose of this study is to develop a technique that is capable of identifying neurophysiological biomarkers sensitive enough to detect preclinical dementia by integrating Transcranial Magnetic Stimulation (TMS) and Functional Magnetic Resonance Imaging (fMRI). More specifically, this project has two specific aims: - 1. To characterize cortical excitability and its relation to cognitive function using single-pulse TMS paradigm in Mild Cognitive Impairment (MCI) and healthy older adults. - 2. To delineate cortical plasticity and its association to cognitive function using repetitive TMS paradigm and resting-state fMRI in MCI and healthy older adults. Techniques to artificially and precisely stimulate brain tissue are increasingly recognized as valuable tools both in clinical practice and in cognitive neuroscience studies among healthy individuals. Transcranial magnetic stimulation (TMS) is a non-invasive approach to stimulate the brain. Importantly, unlike other invasive brain stimulation techniques (e.g., surgical deep brain stimulation), no surgery, anesthesia, or sedation is involved. Instead, TMS involves placing a magnetic coil on the surface of the head. This coil then generates a magnetic field that is about the same strength as the magnetic field used by MRI machines, and when this magnetic field rapidly alternates, the neurons under the coil are excited. Extensive guidelines have been published by experts in the field to ensure safe use, and the thousands of patients & research participants who have received TMS in compliance with these guidelines demonstrate the safety of this practice. Depending on the method of use, TMS is very versatile -- it can be used to study research questions pertaining to the neural circuitry of the brain, it can be used as a diagnostic device, and it can be used therapeutically to treat various neurological conditions. In this study, the investigators intend to further study the potential for diagnostic applications of TMS. More specifically, TMS and brain imaging techniques will be used in combination in order to more sensitively diagnose dementia - perhaps even before symptoms emerge. Right now, there is no reliable method for doing so and it is difficult to distinguish between the forgetfulness of healthy aging and the early signs of disease. Our approach may provide a more sensitive diagnostic tool, which is likely to improve clinical outcomes.
