Filter by:Anesthesia and perioperative Neurocognitive Disorders in the Elderly patients undergoing hip fracture Surgery platform trial (ANDES platform trial): A pragmatic multi-arm, adaptive, open label, multicenter randomized controlled platform trial to assess the effect of different enhance anesthesia technique in perioperative neurocognitive function, as compared to standard anesthesia care in the elderly patients undergoing hip fracture
The purpose of this study is to explore the effect of a dual-task training intervention on cognitive function,physical function, depression symptoms and quality of life in middle-aged and elderly people with cognitive impairment. A Randomized experimental research design is conduced to recruited 196 middle-aged and elderly people: potentially reversible or reversible cognitive decline to attend this study. All participants are randomly allocated into dual-task training, walking training alone, and cognitive training alone and the waiting list control group. The measurements include: demographic and disease data, frailty symptoms (The FRAIL Scale ,Time up and go test ,Sit-to-stand test), cognitive function (Montreal Cognitive Assessment Scale Chinese version), depressive symptoms (Chinese version of Clinical Depression Symptom Assessment Scale) and life Quality (Taiwan's simplified version of the World Health Organization Quality of Life Questionnaire). The results of the study will use Generalized Liner Models and Pearson's product difference correlation analysis to confirm the impact of dual task training intervention on physical function, cognitive function, and depressive symptoms in middle-aged and elderly people with cognitive impairment effect on quality of life.
Up to 25% of intensive care unit (ICU) survivors experience cognitive impairment comparable in severity to mild Alzheimer's disease and related dementias after hospital discharge. Older ICU survivors (ages 60 and older) are at highest risk for delirium and subsequent cognitive impairment, which contribute to higher risk for cognitive decline related to Alzheimer's disease and related dementias. Sleep and activity are essential for recovery from critical illness, yet ICU survivors experience both sleep deficiency and profound inactivity. About 75-80% of ICU patients experience circadian dysrhythmia, which contributes to cognitive decline and increases likelihood of developing Alzheimer's disease and related dementias. The scientific premises of the proposed study are: 1) a combined sleep promotion and cognitive training intervention will have synergistic effects to mitigate the risk of cognitive impairment and development of Alzheimer's disease and related dementias in older ICU survivors; and 2) chronotherapeutic timing of interventions (i.e., adjusting timing of interventions according to circadian rhythm) may improve intervention efficacy.
The goal of this clinical trial is to learn about and describe how pianistic training influences the development of Alzheimer's disease. The key question is: Can pianistic practice influence the development of Alzheimer's disease? Participants will receive piano lessons for 4 weeks (20 sessions) and we will evaluate the evolution of the different parameters described by the tests carried out.
Detecting memory problems early is crucial for treating conditions like Mild Cognitive Impairment (MCI), which often leads to dementia. Currently, doctors use tests in clinics to check for these issues. However, there's a growing need for better methods to monitor our cognitive skills over time. Computer games emerge as a cost-effective solution for assessing the brain functions of older adults. In our study, we are investigating the potential of computer games to reflect the cognitive skills of older adults. We developed the VibrantMinds platform, featuring five games: Whack-a-Mole, Bejeweled, Mahjong Solitaire, Word Search, and Memory Game. We have evaluated these games for ease of use, enjoyment, and their impact on brain functions. Now, our goal is to determine whether these games can offer valuable insights into the cognitive skills of older adults. We are collecting demographic data, game-playing data, and cognitive test results. Our analysis will determine the correlation between game data, cognitive test outcomes, and demographic information. Additionally, we will assess both the perceived and observed engagement of older adults as they play the games.
Dementia is the most common disease in older individuals and this century's biggest healthcare challenge. Many patients who visit the memory clinic with memory complaints do not have dementia but instead are diagnosed with mild cognitive impairment (MCI) or subjective cognitive decline (SCD). MCI or SCD may be a pre-dementia stage. Many patients with MCI or SCD often leave their consultation with unanswered questions, and unsure what they, themselves can do to reduce dementia risk. Patients with MCI and SCD have a heightened risk of developing dementia. Therefore, this group would possibly benefit most from preventive strategies. Around 40% of dementia cases is attributable to modifiable factors. Thus, managing a healthy lifestyle may reduce dementia risk. To answer the information request many patients have when leaving the memory clinic and to fill the knowledge gap an online tool has been developed. The goal of this mixed-method feasibility study is to investigate the usability, feasibility, patient experience, and effectiveness of the personalized, multi-domain online website in older adults with MCI or SCD. The main questions it aims to answer are: - Is the new website being used by the target population? - How does the target population experience the use of the website? - What is the effect of using the website? Participants will have access to the website and are free to use the website in any way they want.
The goal of this clinical trial (Balanced-2 study) is to compare light to deep general anesthesia using widely available brain monitors, to see if 'light' anesthesia could reduce rates of delirium, cognitive decline, and disability in older adults undergoing major surgery. Delirium is the most common serious surgical complication, occurring in an estimated one in four older adults undergoing major surgery. Delirium causes significant distress to patients and family, and is associated with prolonged hospital stay, physical disability, progression to dementia-like illnesses, and discharge to long-term care. Between 10 - 30% of adults aged 70 years and above have surgery every year, and preserving brain health and wellbeing is an important priority during this time. Older adults (aged ≥65 years, or Indigenous, Pasific patients aged ≥55 years) undergoing major surgery with general anesthesia (excluding heart and brain surgery) and able to provide consent will be able to participate. Participants will be randomized to two groups - a lighter general anesthesia group and a deeper general anesthesia group using processed electroencephalography (a brain monitor that provides information on depth of anesthesia using brain waves). The anesthesiologist will titrate anesthetic drugs according to the brain monitor. Participants will be followed up to determine if they experience delirium after surgery, and longer term impact of delirium such as cognitive and physical decline will also be measured. If found to be effect, this simple, cheap, and widely available treatment could reduce disability, preserve brain health and wellbeing of many older adults undergoing surgery worldwide, and save millions in healthcare dollars.
The goal of clinical trial is to learn about how blood pressure fluctuations affect cognitive performance (thinking abilities) and brain blood flow in persons with Parkinson's disease with and without orthostatic hypotension (low blood pressure when standing). The main questions it aims to answer are: - Is there a certain level of blood pressure that correlates with change in cognitive performance while upright? - Is there a certain level of change in brain blood flow that correlates with change in cognitive performance when upright? - How does cognitive performance differ between persons with Parkinson's disease that have orthostatic hypotension and those without orthostatic hypotension? - How does cognitive performance differ between the supine (laying down) and upright positions? - How do blood pressure and brain blood predict changes in cognitive performance over two years? Participants in this study will undergo the following procedures: - Complete a screening visit with questionnaires, medical history, physical exam, and head-up tilt-table test. - Attend one baseline study visit, during which they will undergo a battery of computerized cognitive tests repeated twice: once while laying down and once while upright on a tilt table. Simultaneously, during the experiments we will measure blood pressure using a wrist-worn device and inflatable arm cuff and will measure brain blood flow using functional near-infrared spectroscopy (fNIRS), a non-invasive device that uses light sensors to detect changes in brain blood flow. - Attend one two-year follow-up visit, during which they will repeat a battery of computerized cognitive tests repeated twice: once while laying down and once while upright on a tilt table. During this visit, like before, we will measure blood pressure using a wrist-worn device and inflatable arm cuff and will measure brain blood flow using functional near-infrared spectroscopy (fNIRS). Researchers will compare participants with Parkinson's disease with and without orthostatic hypotension in the laying down and upright positions to see if there are changes in thinking abilities between these groups.
The current project is dedicated to creating a comprehensive cognitive and neural assessment platform and corresponding norms tailored specifically to the older adults in Macau.
Older veterans with a history of mild brain trauma exhibit early cognitive challenges, especially in driving-related tasks. This is attributed to alterations in the brain's excitatory/inhibitory (E/I) balance. This pilot project investigates this phenomenon by leveraging electroencephalography (EEG) to measure parietal lobe alpha rhythms during visual attention tasks. The hypothesis is that targeted visual attention training can modulate these alpha rhythms, improving instrumental activities in daily life. However, outcomes from such training vary, possibly due to individual differences in cortical inhibitory functions. This study will assess the relationship between EEG measures of E/I balance pre- and post-visual attention training and its effects on processing speeds in aging veterans. Our findings aim to provide a foundation for customized therapies and interventions for veterans with and without a history of brain trauma.
