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 aim of the study is to compare physical fitness, walking speed and hand reaction time measurements in older adults with different cognition levels according to the Montreal Cognitive Assessment Scale (MOCA).
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.
To date, the effects of pain on motor learning have not been thoroughly investigated, particularly in older adults. Broadly, the purpose of this research is to investigate the impact of acute pain on locomotor learning and its retention in older adults. The investigators hypothesize that acute pain impairs retention of locomotor learning in young and older adults and that in older adults, these deficits are worsened and are related to the degree of normal age-related cognitive decline.
This randomized controlled trial (RCT) is used to address the knowledge translation of primary care practitioners (PCPs) for the early identification of cognitive impairment. Cognitive impairment is experienced by people with many different underlying health problems, e.g., diabetes, cardiovascular problems, COVID-19, neurodegenerative diseases, and mental health problems. Older adults are more likely to have cognitive decline which may develop into Alzheimer's disease or dementia but 40% of dementia can be prevented by managing the risks. Cognitive impairment can demand vast societal resources, the burden is reported to be more among Hispanics and blacks. By 2029, all baby boomers will be over 65, comprising at least 20% of the U.S. population. So, it is critical for PCPs to effectively identify, prevent, and manage the hidden signs of cognitive impairment. People with early signs of cognitive impairment will have opportunities to benefit from suitable cognitive remediation to reverse it or prevent rapid progression. It is critically important for people who are socioeconomically disadvantaged, those who are black, indigenous, and people of color (BIPoC). These people are often served by safety-net hospitals, such as clinics of the Los Angeles County (LAC) Department of Health Services and the federally qualified health centers at the Community Clinics Association of LAC. Many PCPs in these clinics are often BIPoC. The intervention used in this RCT is called "Cognition ECHO" based on the proven model of ECHO (Extension of Healthcare Outcomes) for knowledge dissemination and translation. Cognition ECHO is a virtual activity incorporating a short didactic presentation and de-identified case discussion to solve real-world patient care challenges and ease direct knowledge translation. PCPs in the LAC will be randomized into Groups 1 and 2. Group 1 will attend the five Cognition ECHO for four months, Group 2 will be the control. Group 2 will attend Cognition ECHO starting on July 25, 2023, five times till November 7, 2023, when Group 1 is the follow-up. Most sessions are scheduled on the fourth Tuesday of the month with the addition of June 6 and November 7, 2023. Focusing on cognitive impairment and targeting PCPs at the LAC, the goal of this study is to evaluate if Cognition ECHO can improve PCPs' capacity to detect early cognitive impairment and manage it. It will result in opportunities to mitigate the risk factors of early cognitive impairment, especially for minority patients in LAC, and conduct efficacy studies in the future to address cognitive impairment focusing on BIPoC.
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.
