Filter by:Background: Arterial disease of the legs causes symptoms such as pain when walking and may ultimately lead to a leg amputation. Many older people with arterial disease of the legs also have problems with their thinking and memory. Blood flow in the brain may be altered in these people and may be a cause for memory and thinking problems. Aim: The aim of this project is to investigate whether people with arterial disease of the legs have altered blood flow in the brain causing problems with memory and thinking. Research plan: Twenty people with arterial disease of the legs causing pain while walking and twenty healthy people will have a series of non-invasive assessments. Arterial disease in the legs will be measured using ankle blood pressures before and after walking. Blood flow in the brain will be measured using ultrasound whilst performing memory and thinking tests. Results will be compared between the people with arterial disease in the legs and the healthy people to see if there are any differences in blood flow to the brain and memory and thinking. Benefits to society: This project will help determine if there is a link between arterial disease of the legs and memory and thinking problems caused by altered blood flow in the brain. It will enable future research in people with cognitive impairment caused by altered blood supply to the brain and to prevent confusion and further memory and thinking problems in people undergoing surgery for arterial disease of the legs.
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.
Computer games are increasingly utilized as tools for studying cognitive skills, aging, individual differences, and development. They offer a unique advantage by presenting challenges that more closely mirror the complexities and demands of everyday tasks compared to traditional laboratory experiments, clinical tests, and standardized assessments. Our team took an innovative step in this direction by developing a suite of tablet-based games, titled VibrantMinds. These games, varying in type, are designed to measure diverse cognitive indicators, acting as proxies for assessments typically conducted using paper-and-pencil tests in clinical settings. VibrantMinds games have been specifically crafted to be user-friendly and engaging for older adults, including those with dementia. Our studies have shown that these individuals not only find the games accessible but also exhibit measurable improvement in gameplay, suggesting potential benefits for cognitive skill training. Building on this foundation, we are now poised to conduct an in-depth investigation into the actual effectiveness of serious computer games (SCGs) for cognitive enhancement and their application in real-world settings for older adults. This next phase of research will leverage the VibrantMinds platform to carry out studies aimed at validating software-defined indicators of cognitive function and measuring the impact of game-based interventions on cognitive abilities, health-related quality of life, and other significant real-life outcomes. The anticipated results promise to expand our understanding of the potential for new technologies in cognitive assessment and intervention. Moreover, by employing machine learning analysis of the data collected through VibrantMinds, we aim to develop a taxonomy that correlates game complexity and player performance with conventional clinical instruments for assessing cognitive status and functioning.
To assess the effect of Dexmedetomidine on serum Tau-217 protein and its relation to the incidence and severity of postoperative cognitive dysfunction in elderly patients undergoing major surgery under general anesthesia.
Depressed mood is the main symptom of depression, but other symptoms like cognitive impairment, anhedonia or sleep disorders may also contribute to patients suffering and are difficult to treat. rTMS is a relatively novel treatment option, whose therapeutic potential is still investigated and optimized. The aim of this study is to assess the effect of rTMS applied over two stimulation sites on cognitive impairment, anhedonia and sleep disorders in depression.
This study is the academic study and continuation and further development of a prior project under the leadership of Professor LeBlanc. Patients undergoing allogenic stem cell transplantation are followed up in the outpatient clinic. Here, patients are offered participation the fatigue study measuring both fatigue and cognitive impairment systematically by international standard. Previous study by Boberg et al suggested distinct mRNA and proteomic profiles segregating fatigued from non-fatigued patients as well as patients with or without cognitive impairment. A larger well-defined patient cohort is necessary to confirm these results. Investigators aim to identify specific sets of proteins in the CSF that can serve as potential biomarkers of cognitive dysfunction and/or fatigue. This will be performed with two methods: - by using mass spectrometry-based proteomics approaches - Olink technology PET examinations will be performed on both fatigued and non-fatigued. We will utilize the second generation TSPO radioligand [ 11C]PBR28 as well as the SV2A radioligand [ 11C]UCB-J, both showing high signal-to-noise ratio and adequate test-retest properties.
The goal of this placebo-controlled double-blind Phase 2 clinical trial is to test in people with early Alzheimer's Disease. The main questions it aims to answer are: - Does treatment with fasudil, a ROCK-inhibitor, lead to significant improvement in working memory (based on computer-based working memory composite scores) compared to placebo in individuals with early Alzheimer's disease (AD) over 12 months? - What is the effect of fasudil treatment for 12 months on other cognitive functions, brain metabolism measured by Fluorodeoxyglucose Positron Emission Tomography (FDG-PET), and other relevant clinical functions and biomarkers in individuals with early Alzheimer's disease (AD)? - Treatment will be escalated to a maintenance dose of 120 mg total daily dose for up to 50 weeks, with regular clinic visits for efficacy and safety evaluations. - Assessments will include cognitive tests, FDG-PET scans, and biomarker analyses, with follow-up by the Data and Safety Monitoring Board for ongoing safety review. The study will compare participants receiving fasudil with those receiving placebo to see if fasudil treatment leads to improvements in cognitive functions, brain metabolism measured by FDG-PET.
The purpose of this study is to assess the feasibility, acceptability, and fidelity of an 8-week intervention where peer coaches will deliver depression care to adults 60 years of age or older who have depression and subjective cognitive decline.
The purpose of this research study is to investigate the relationship between light and circadian rhythms. Twenty healthy older adults will be recruited to participate in a randomized, cross-over study, where an active lighting intervention designed to maintain entrainment and a control intervention designed not to entrain will be tested.
This is to find out the effectiveness of cognitive and physical function training for patients with mild cognitive impairment. It is for the prevention and treatment of dementia in the future. randomized, Pilot Study.
