Filter by:The goal of this pilot randomised clinical trial is to compare a 12-week Healthy Body & Mind Program to usual care in older adults living with cognitive decline and osteoarthritis. The main questions it aims to answer are: - Does the Healthy Body & Mind Program improve health-related quality of life in older adults living with cognitive decline and osteoarthritis (pre/post and intervention/control)? - Does the Healthy Body & Mind Program improve other health outcomes (cognition, pain, anxiety/depression, physical function) in older adults living with cognitive decline and osteoarthritis (pre/post and intervention/control)? Participants will complete a co-designed and multidisciplinary 12-week program that includes physical activity and lifestyle education (nutrition, social activity and managing anxiety/depression). Researchers will compare outcomes between the intervention group and a wait-list control to see if there are difference in outcome measures (quality of life, cognition, pain, anxiety/depression, physical function).
The goal of this prospective cohort study is to assess potential differences in sleep biomarkers in older adult patients undergoing major orthopedic surgery. The main questions it aims to answer are: 1. To define sleep/circadian biomarkers of delirium (sleep duration, regularity, stability and timing of rhythm) in a prospective observational study. 2. To determine if plasma Alzheimer's disease (AD) pathology/inflammatory burden interacts with or moderates the relationship between a sleep/circadian biomarker and post-operative delirium (POD) risk. 3. To determine whether sleep/circadian regulation interacts with the genetic risk of AD to influence POD/cognitive decline. Participants will be asked to: 1. Donate several blood samples both intraoperatively and postoperatively 2. Complete baseline and postoperative neurocognitive assessments 3. Wear an actigraphy data collection watch for the two weeks prior to their surgery
Randomized, placebo-controlled, double-blinded, parallel group clinical trial to investigate if 6 months of oral lithium tablets (S-lithium 0,5-1,0 mmol/l) will prevent cognitive decline after brain radiotherapy in pediatric brain tumor survivors. Primary outcome measure is Processing Speed Index (PSI) 2 years after start of study treatment.
This observational study will examine the association of chronic traumatic cerebrovascular injury and cardiovascular risk factors with TBI-related cognitive impairment and vascular dementia. Cerebrovascular, inflammatory, and neurodegenerative blood biomarkers as well as clinical and neuroimaging data
There is a major unmet need for timely, non-invasive, and low-burden evaluation of patients presenting with mild cognitive impairment (MCI) and dementia. MCI impacts 12-18% of people in the United States over age 60 years (Alzheimer's Association. Mild Cognitive Impairment (MCI) available at https://www.alz.org/alzheimers-dementia/what-is-dementia/related_conditions/mild-cognitive-im pairment. Accessed August 16, 2022). MCI does not substantially interfere with daily activities, although complex functional tasks may be performed less efficiently (Knopman DS, Petersen RC. Mild cognitive impairment and mild dementia: a clinical perspective. Mayo Clin Proc. 2014;89(10):1452-1459. doi:10.1016/j.mayocp.2014.06.019). Approximately 30% of MCI patients have Alzheimer's disease (AD) as a cause of their symptoms (Lopez,OL, Kuller LH, Becker JT, et al. Incidence of dementia in mild cognitive impairment in the cardiovascular health study cognition study. Arch Neurol. 2007;64(3):416-420.doi:10.1001/archneur.64.3.416)). In contrast, dementia is defined by chronic, acquired loss of two or more cognitive abilities caused by brain disease or injury, often associated with significant interference with the ability to function at work or at usual activities. (Knopman DS, Petersen RC. Mild cognitive impairment and mild dementia: a clinical perspective. Mayo Clin Proc. 2014;89(10):1452-1459. doi:10.1016/j.mayocp.2014.06.019). Approximately 60-80% of dementia patients have AD as a cause of their symptoms (Alzheimer's Association. Mild Cognitive Impairment (MCI) available at https://www.alz.org/alzheimers-dementia/what-is-dementia/related_conditions/mild-cognitive-im pairment. Accessed August 16, 2022).
In a society with increased life expectancy, the economic, social and personal burden of dementia increases. Dementia is often caused by a combination of neurovascular and neurodegenerative diseases. Impaired brain clearance is suggested to be closely related to dementia development, as waste products (e.g. amyloid beta) accumulate in the brain, leading to neurodegeneration. Cerebral small vessel disease (SVD) is the most common neurovascular disease that even contributes to about 45% of dementia pathophysiology in patients with a diagnosis of Alzheimer's dementia. White matter hyperintensities of presumed vascular origin (WMH) are the key brain MRI manifestation of cerebral SVD. There is evidence that the currently known and MRI-visible WMH are landmarks of an already progressed stage of the underlying pathology. The pathophysiology of WMH has been attributed to multiple underlying mechanisms, such as hypoperfusion, defective cerebrovascular reactivity and blood-brain barrier dysfunction. Furthermore, different anatomical locations and different types of WMH are related to different underlying pathological changes. Using ultra-high field 7T MR imaging techniques WMH lesions can be detected with a higher sensitivity and resolution than on 3T MRI. The hypothesis is that different pathological mechanisms of cerebral SVD lead to variations in WMH shape. Moreover, the brain clearance ('glymphatic') system of the brain appears to be tightly connected to dementia pathology. Thus, novel markers of glymphatic activity could aid to describe and understand the pathology.
Older South Asian family caregivers experience elevated psychological stress and limited physical activity (PA) due to caregiving responsibilities and additional factors such as lack of access to services, cultural/linguistic barriers, stigma and discrimination. South Asian family caregivers are especially underserved and are a growing ethnic group in the US. Both PA and cognitive training (CT) have shown to improve cognitive function in older adults who experience cognitive function decline because of psychological stress. However, there are no studies using this approach for this population. We propose a randomized control trial pilot study to address this gap. Driven by a Community Advisory Committee (CAC) we will develop this 12-week mindful walking intervention using a participatory research methodology in partnership with UIC's Cognition Behavior and Mindfulness Clinic that combines the PA of walking and the CT through mindfulness. We will recruit fifty participants and will randomly and equally assign 25 people to the intervention and 25 people to the control group. The intervention will include: 1) a mindful walking training followed by 2) a prescribed mindful walking regimen, 3) self-reporting of adherence to regimen by the participants using activity logbooks and use of a user-friendly PA tracker (Fitbit) for daily step count, and 4) personalized text messages with reminders and motivational messages for participants to do the mindful walking as prescribed including a weekly check-in call or text message for accountability. The primary aim of the proposed pilot study is to evaluate the feasibility and acceptability of the protocol and intervention implementation. A secondary aim will evaluate the intervention to examine preliminary efficacy in reduction of psychological stress, improvement in cognitive function, increase in physical activity, and increased self-efficacy (self-efficacy for coping with stress, self-efficacy for physical activity, and overall self-efficacy). The findings of this pilot project will provide evidence-based data to support a larger scale study proposal for future funding such as the National Institute on Disability, Independent Living, and Rehabilitation Research (NIDILRR) field initiative award, or the National Institute of Health (NIH) Research Project Grant (R21 NIH Exploratory/Developmental Research Grant Award) award, especially National Institute on Aging (NIA) grants.
The current study is a mechanistic study to evaluate working memory gains from application of transcranial direct current stimulation (tDCS) in older adults with mild cognitive impairments (MCI) compared to cognitively healthy control
The potential impact of various dietary ingredients to improve cognitive function, mood, well-being, and overall levels of affects are largely undetermined. The purpose of this study is to determine the effects of a combination of two dietary supplements, Scutellaria baicalensis and Acacia catech, on cognitive function, well-being, mood, cognitive interferences, and inflammation.
This study aims to investigate the effect of computerized vestibular function assessment and interactive training system, combined with cognitive/motor dual-task for the elderly with dizziness. The investigators will compare the movement abilities among older adults with different cognitive level, and further establish an assessment module that can evaluate participants' dual-task performance in both vestibular and cognitive tasks. Finally, leveraging the advantages of sensor detection technology and computerized feedback, an appropriate dual-task rehabilitation approach for vestibular function and cognition will be developed.
