Filter by:To compare alternation of retinal microcirculation within the macula and optic disc in patients with dementia, mild cognitive impairment (MCI), and cognitively healthy subjects who had positive amyloid biomarkers (Aβ +) or not, using optical coherence tomography angiography (OCTA).
The purpose of this study aims to explore the surplus effect of arch support insole to a cognicise training program on lower-extremity function in community-dwelling older adults with mild cognitive impairment (MCI). In this randomized controlled intervention study, we will recruit 40 community-dwelling individuals aged ≥55 years with MCI. Experimental group (n=20) will receive cognicise training program with insole intervention (6 hours/day), while the control group (n=20) only undergo cognicise training. A 1-h training session will be given three times a week for 12 weeks for both groups. The outcomes include static standing balance, functional reach test, timed-up-and-go test, 10-m obstacle crossing, the Short Physical Performance Battery (SPPB), and gait assessment during single- and dual-task walking for 20 m at self-selected comfortable pace while performing serial subtractions (cognitive interference) or carrying a tray (motor interference). The results of the current study are expected to provide evidences in supporting the use of arch support insole among community-dwelling older adults with MCI. Interventions combing physical-cognitive training and insole for providing mechanical stability and somatosensory stimulation may serve as potential strategies for fall prevention.
This study aims to explore the effects of arch support insoles on balance and gait performance in older adults with mild cognitive impairment (MCI). We will recruit 40 female older adults with MCI. A randomized crossover trial will be used to determine the immediate effect of arch support insoles. All participants received one assessment session wearing and one session not wearing insole in a random order within 1-day. Then participants will be randomly allocated to experimental group (arch support insoles, n=20) or control group (no insoles, n=20) for at least 4-h every day for 1-month. Our primary outcomes include static standing balance, timed-up-and-go test, 10-m obstacle crossing, functional reach test, Short Physical Performance Battery (SPPB), and gait assessment during single- and dual-task walking for 20 m at self-selected comfortable pace while performing serial subtractions (cognitive interference) or carrying a tray (motor interference). Assessments will be conducted at baseline and after 2-wk and 4-wk of insole wear. Statistical analyses will be performed using SPSS 21.0 software. Two-way mixed ANOVA will be used to determine the immediate and short- and long-term effect of arch support insoles. The results of the current study are expected to provide evidences in supporting the use of arch support insoles for improving gait performance and postural stability for older adults with MCI which will contribute to balance and gait training as well as fall prevention.
Phase 1b study to assess the pharmacodynamics, safety, tolerability, and pharmacokinetics of NIO752 in patients with early Alzheimer's disease (AD)
The purpose of this study is to assess the safety and feasibility of administering standard of care monoclonal antibody (mAb) infusion therapy in combination with opening the blood-brain barrier with the Exablate Model 4000 Type 2 device in patients with mild Alzheimer's disease (AD) or mild cognitive impairment (MCI).
This is a multi-center longitudinal study that consists of five cohorts: cognitive normal aging (CN), Subjective cognitive impairment (SCI), mild cognitive impairment (MCI), Alzheimer's disease (AD) and vascular cognitive impairment (VCI). The goals of this study are as follow: 1.To establish longitudinal cohort study database containing comprehensive epidemiological data, neuropsychological test data, laboratory parameters, image data and biological samples. 2. To determine the risk factors of AD and other dementias. 3. To explore the conversion rates from CN to SCI, MCI or AD and the risk factors as well as biomarkers for the progression from CN to SCI, MCI or AD. 4. To explore and validate blood, CSF, urine, imaging and other biomarkers for the early detection and progression of AD.
The primary objective of this study is to investigate whether a tablet-based role-playing game is more effective than tablet-based word or image puzzles at improving executive functions in older adults with mild cognitive impairment. The secondary objective of this study is to investigate whether a tablet-based role-playing game will show higher levels of engagement (measured by time played) in older adults with mild cognitive impairment than tablet-based word or image puzzles.
Researchers at the University of North Carolina at Greensboro conduct a single-arm intervention trial to investigate the efficacy of a music-based group exercise program for community-dwelling older adults. Up to forty participants will be recruited to participate in a music-based light-to-moderate intensity group exercise program for 20 weeks (30 - 40 min/day, up to 6 days/week), which is designed for older adults with or without functional limitations to exercise with chairs for the improvement of aerobic capacity, upper and lower body strength, and balance control at a gradually increasing pace. During the exercise sessions, participants will be trained to move in time with music playlists in synchronous tempos. Primary outcomes are cognitive performance, mobility, and health-related quality of life measured before and after the intervention. Secondary outcomes are adherence to the exercise program as a potential mediator of the treatment.
The proposed research will use closed-loop transcranial magnetic stimulation (TMS) based on individualized brain networks to establish parameters that can reliably control brain states. This will be tested in healthy aging and mild cognitive impairment (MCI) cohorts. The investigators will study network activation and neural oscillatory mechanisms underlying the network that regulates working memory and then target this network using closed-loop TMS to the Prefrontal Cortex. Investigators will measure the impact of TMS on working memory performance and task-based neural activity. The project will use brain stimulation and network modeling techniques to enhance working memory in healthy older adults and MCI and will demonstrate the value of closed-loop, network-guided TMS for future clinical applications.
Dementia is associated with a variety of neurovascular and neurometabolic abnormalities. Traditional imaging techniques used to investigate such abnormalities, such as Positron Emission Tomography and functional Magnetic Resonance Imaging, are not always well tolerated, have expensive start up and running costs, and are limited with regards to the types of experiments that can be performed as they can be highly sensitive to movement, are noisy, and have physical restrictions. Near-infrared spectroscopy (NIRS) is a non-invasive neuroimaging technique which uses light in the near-infrared spectrum to detect relative changes in concentration of oxygenated and deoxygenated haemoglobin, and the oxidation state of Cytochrome C Oxidase. As such, NIRS can provide measures of brain oxygenation and metabolism. NIRS is less sensitive to movement, is well tolerated and has few contraindications. It is thus a promising candidate for use in clinics or in peoples' homes for monitoring dementia. In the present study, the investigators aim to use both dual-wavelength and broadband NIRS in a range of dementia subtypes, including Alzheimer's Disease and Dementia with Lewy Bodies, and severities, including Mild Cognitive Impairment, to identify how brain oxygenation and metabolism is altered in dementia and across various clinical subgroups. The investigators also aim to determine the relationship between brain oxygenation and metabolism in dementia, and use machine learning approaches to identify optical biomarkers for dementia.
