Filter by:Alzheimer's Disease (AD) is the most common form of dementia and may contribute to 60-70 % of all cases. An early, accurate diagnosis of AD will become increasingly important with disease-modifying therapies. Different types of fluid and neuroimaging biomarkers are available for the early detection of AD. However, implementation of routine use of these biomarkers in clinical settings is held back due to the risk of overdiagnosis, increased cost and invasiveness of the assessment method. Therefore, novel biomarkers are needed beyond the amyloid and tau pathologies for the early diagnosis of AD. Neuropsychological paper and pencil tests can detect AD and discriminate between different clinical stages. Since medial temporal lobe structures, including the hippocampus and entorhinal cortex (EC), are involved in spatial navigation and degenerate in the earliest stages of AD, spatial navigation can be considered as an early cognitive biomarker of the disease. Nonetheless, the measurement of spatial navigation needs further improvement since the current paper and pencil tests lack ecological validity. Therefore, the test environment should be set up in immersive Virtual Reality (iVR). Dr. Andrea Castegnaro (Space and Memory Lab of University College of London) developed the Allocentric Spatial Update Task (ALLO task), which is an iVR task measuring egocentric and allocentric spatial abilities. Therefore, the main objective of this study is to evaluate whether allocentric and egocentric spatial navigation, measured by the ALLO iVR task can be considered a cognitive biomarker for the early detection of AD. In addition, the investigators want to report on the neuronal correlates of both spatial navigation strategies. Through the Department of Neurology of the University Hospital of Ghent, which has a large cognitive disorders clinic, patients with mild cognitive impairment and mild Alzheimer's dementia will be recruited. Participants will undergo standard clinical assessment, including a neuropsychological examination, Magnetic Resonance Imaging, a 18F-fluorodeoxyglucose PET and a Lumbar Puncture. In addition, participants will also be asked to undergo Tau PET imaging, Amyloid PET imaging and complete the ALLO iVR task. Healthy controls will also be recruited and have to undergo the same investigations, except for the amyloid PET and lumbar puncture.
This study aims to assess the feasibility and efficacy of a 10-weekly multi-domain VRCT program on the cognitive function (i.e. attention, memory, and executive functioning) of older adults with MCI.
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.
This project aims to understand the feasibility, acceptability and real-world evidence of a novel UK-based remote brain health clinic for patients with mild cognitive impairment (MCI). A timely and accurate diagnosis of dementia is a priority in the UK and MCI is indicative of future risk of cognitive decline. An accurate etiological diagnosis of MCI (MCI-subtyping - distinguishing those who are likely to go on to develop dementia and those who are not) is vital for treatment planning. Whilst the assessment of molecular biological markers (biomarkers) for etiological diagnosis of MCI and Alzheimer's disease (AD) is increasingly recommended and employed internationally, the uptake is low in UK memory clinics. The Brain Health Clinic (BHC) has been specifically designed as a state-of-the-art diagnostic centre for those with MCI. Procedures will include a range of clinical and biomarker assessments, with molecular biomarkers based on lumbar puncture and cerebrospinal fluid (CSF) analysis. Additionally, the clinic will employ remote neuropsychiatric assessments using digital and telephonic methods. This allows for regular contact, whilst adhering to changes in clinical practice and national guidance due to the COVID-19 pandemic. Our overarching objectives are to first establish the acceptability and feasibility of the remote Brain Health Clinic and its novel clinical and biomarker assessment programme. Then secondly establish the impact of care under the Brain Health Clinic on i) care management decisions (e.g. follow-up and treatment planning); ii) time to etiological diagnosis of MCI (MCI-subtyping); and iii) time to diagnosis of dementia and severity of dementia at the time of diagnosis.

This study aims to evaluate the effectiveness and cost-effectiveness of CST-ES, the Spanish adaptation of Cognitive Stimulation Therapy (CST), to improve cognition and quality of life in people with mild to moderate dementia. The evaluation will be conducted as a pragmatic multicenter randomized controlled clinical trial. Participants will be randomized to receive 7 weeks of CST-ES followed by 24 weeks of maintenance CST-ES (intervention group) or to continue their usual treatment (control group).
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.
