Filter by:This cross-over pilot study aims to study the acceptability of two methods of non-invasive brain stimulation for the treatment of Parkinson's disease mild cognitive impairment (PD-MCI) - repetitive transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation (tDCS) targeted at the left dorsolateral prefrontal cortex (DLPFC). Twenty participants will undergo both interventions in a cross-over design. They sequentially undergo four consecutive phases (4 weeks each), 1) no-intervention baseline, 2) rTMS ór tDCS, 3) no-intervention, 4) second intervention. The primary outcome measure will be acceptability of the interventions, and secondary outcomes include feasibility, cognitive function, neuropsychiatric symptoms, motor function. We will use MRI to explore personalized targeting.
This study aims to (1) develop and assess the feasibility of a fi-VRCT program based on IADL for older adults with MCI, (2) implement and evaluate the effectiveness of the fi-VRCT program based on IADL in older adults with MCI, and (3) investigate the potential mechanism of the fi-VRCT program based on IADL for older adults with MCI and refine this intervention accordingly.
Using simultaneous multimodal neuroimaging (FDG-PET, fMRI, EEG), this research project will aim to further investigate in vivo brain insulin signalling by exploring the effects of acute INI administration on neurometabolic and neurovascular coupling, and on cortical electrical activity, both in individuals with normal cognitive function and those affected by Mild cognitive Impairment and Alzheimer's Disease .
Alzheimer's disease (AD) is a neurodegenerative disorder characterized by progressive cognitive dysfunction and behavioral impairment. It is currently the most common type of dementia in the old age. At present, the clinical treatment of Alzheimer's disease is expensive and has side effects, so it is very important to explore new methods of treatment for AD. Investigators designed a prospective, randomized, double-blinded and placebo-controlled trial to investigate the effect of transcranial alternating current stimulation (tACS) on cognitive function in AD patients and to assess the biological effectiveness of the treatment.
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.
To determine the relationship between the effects of different frequencies and duration of Tai Chi Chuan in dose parameters to improve cognitive function in elderly persons with mild cognitive impairment.
To determine the impact of Tai Chi Chuan with different exercise volume on cognitive function in elderly patients with mild cognitive impairment.
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.
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.
