Filter by:This is a comparative, double-blind, randomized controlled clinical trial for people with Amnestic Mild Cognitive Impairment. The investigators will compare the effects of two non-invasive neuromodulation techniques (Repetitive Transcranial Magnetic Stimulation and Transcranial Direct Current Stimulation) combined with cognitive stimulation. These non-invasive neuromodulating techniques will be applied as a treatment alternative to be able to compare non-invasive techniques with cognitive stimulation CS alone, taking into account clinical and neuropsychological evaluations in addition to: 1) the known clinical risk factors (physical activity, comorbidities treatment, etc.) that allow the investigators to characterize the participants; 2) characterize the participants with genetic biomarkers using the APOE4, CR1, COMT, TREM2 and ABCA7 genotype; 3) document the biological effects related to neurogenesis from olfactory epithelial neural progenitor cells and solubles factors of serum; 4) use hippocampal volume, cortical thickness of the medial temporal cortex and parietal cortex by means of structural magnetic resonance imaging and the default mode network by means of functional magnetic resonance imaging at rest as a biomarker of response to treatment and 5) associate the response to treatment with changes in Motor Evoked Potential (MEP) amplitude and latency in order to generate a response-to-treatment biomarker with neuromodulators in Mild Cognitive Impairment (MCI) and changes in electroencephalogram.
This study will evaluate the effects of a form of non-invasive brain stimulation on brain functioning and memory in cognitively intact older adults (healthy controls, HC) and in those with mild cognitive impairment (MCI).
The aging of the global population presents significant social and health challenges. In Aragón, 15% of the population is between 65 and 79 years old, and the over-aging index is 16.6%, higher than the national average. This aging necessitates promoting healthy aging and maintaining functional capacity in advanced ages. Currently, 15% of the Aragonese population is potentially dependent, a figure that rises to 26% among those over 85 years old. The decline in functional capacity is due to auditory, visual, joint, and proprioceptive issues, resulting in increased vulnerability to falls, which are a significant cause of death among the elderly. The frailty syndrome, although common with aging, is not inevitable and is characterized by the loss of functional capacity and increased risk of falls and hospitalization. To assess this capacity in frail individuals, specific tools like the Mini-Motor Test, the Morton Mobility Index, and the Elderly Mobility Scale exist. The BESTest, developed in 2009, evaluates balance but is time-consuming to administer, leading to the creation of a shorter version, the Mini BESTest. However, both can be limiting for frail individuals. To address these limitations, the Frail'BESTest was developed, evaluating six balance subsystems and being suitable for frail individuals, making it a valid and sensitive tool in clinical practice. This research project aims to develop tools that identify balance problems in frail individuals with mild cognitive impairment, allowing for specific interventions to reduce the risk of falls.
The study aims to determine the effects of brain training games on cognitive function and Quality of life among older adults with MCI.
The purpose of this study is to test the Green Activity Program that was designed with Hispanic/Latino people living with memory challenges and their study partners to see if it can be done and if they enjoy the program. "Green activities" are nature activities that the person enjoys and can be done with other people or pets. For example, dog walking, hiking, outdoor yoga, and gardening are all green activities. The purpose of the program is to help people living with memory challenges participate in nature activities they enjoy. The goal of the program is to help people stay active and improve their health and well-being.
This is a proof of concept observational study is to determine if there is correlation between Aβ plaques and vascular findings in the Retina versus brain ARIA.
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.
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.
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.
