Individuals with dementia and their families are especially vulnerable during a disaster as it limits caregivers' ability to continue with care due to disaster related stress and reduced access to resources and support. The COVID-19 pandemic showed the extreme vulnerability of persons with dementia (PWD) and their caregivers as they struggled to access support and resources due to the threat of COVID-19 infection; such impact was exacerbated in rural areas where caregivers are geographically isolated and disaster management resources are scarce. With the number of federally declared disasters increasing dramatically over the past 50 years, active public health efforts are needed to support caregivers in developing emergency caregiving plans usable in disasters such as pandemics and extreme weather emergencies. The long-term goal of this project is to enhance emergency preparedness and support networks of caregivers of PWD to increase their resilience and minimize distress by implementing an intervention program, Disaster PrepWise (DPW). In the DPW program, a trained Medical Reserve Corp (MRC) volunteer will provide step-by-step guidance to caregivers to jointly develop emergency preparedness plans and personal support networks. The objectives of this proposed study are to 1) test the impact of DPW on caregiver outcomes (i.e., resilience, stress) and perceptions that may mediate the association between DPW and outcomes (caregiver self-efficacy, preparedness, social support); and 2) evaluate implementation strategies in a real-world setting to optimize future dissemination. We will conduct a randomized control trial of 200 caregivers of persons with dementia involving two arms: DPW intervention group and an information-only control group (print information on disaster preparedness). Assessments will occur before randomization (baseline), and 3 and 6 months after the baseline. This study is innovative in its use of a highly personalized disaster preparedness program with built-in assistance to support caregivers; the support will be provided through an existing national-level public health infrastructure (MRC) that has a great potential to reach older adults and caregivers in rural areas. The knowledge and data obtained through this study will lay the foundation for a future larger-scale multi-state pragmatic trial to assess dissemination potentials.
The overall aim of this study is to pilot test Promoting Positive Care Interactions (PPCI) with the goal of establishing a feasible and culturally responsive approach to optimize care interactions between staff (nursing, activity, housekeeping, and dining service staff) and residents with ADRD in assisted living facilities (ALFs), and further improve select resident, staff, and facility outcomes. PPCI is a non- pharmacological four-step approach consisting of (1) stakeholder engagement in developing facility specific goals; (2) environment and policy assessments; (3) flexible staff education; and (4) ongoing mentorship, motivation, and support (in-person visits and text messages) for staff to optimize care interactions.
The purpose of this study is to adapt, pilot test, and evaluate the feasibility, acceptability, and preliminary effectiveness of DIGNITY (Decision-making In aGing and demeNtIa for auTonomY) for Preference-Based Care in Nursing Homes as a new evidence-based intervention to support nursing home staff to safely honor care and activity preferences of residents' living with dementia in rural, typically under resourced nursing home communities.
The goal of this double-blinded placebo-controlled randomized trial is to determine the optimal dose of nicotinamide riboside (NR), in individuals with Alzheimer's disease (AD). The main questions the N-DOSE AD trial aims to answer are: What dose of nicotinamide riboside (NR) is required to achieve maximal cerebral nicotinamide adenine dinucleotide (NAD) increase, measured by 31P-magnetic resonance spectroscopy (MRS) or cerebrospinal fluid (CSF) metabolomics)? What dose of nicotinamide riboside (NR) is required to achieve maximal alteration in the cerebral metabolism patterns, measured by fluorodeoxyglucose-positron emission tomography (FDG-PET)? What dose of nicotinamide riboside (NR) will have optimal effect in the absence of unacceptable toxicity? Participants will be asked to do participate in: Clinical examinations Cognitive assessments Lumbar puncture Magnetic resonance imaging - positron emission tomography (MRI-PET) scannings Biosampling They'll be given placebo, 1000 mg NR or escalating doses of NR (1000 mg - 2000 mg - 3000 mg) over 12 weeks.
The purpose of this study is to assess the feasibility, acceptability, and fidelity of implementation of the Mindfulness Based Dementia Care (MBDC) program to reduce depressive symptoms in care partners (CPs) of people living with dementia (PLWD).
Since its launch in 2004, the overarching aim of the Alzheimer's Disease Neuroimaging Initiative (ADNI) Study has been to validate biomarkers for Alzheimer's disease (AD) clinical trials. ADNI4 continues the previously funded ADNI1, ADNI-GO, ADNI2, and ADNI3 studies that have combined public/private collaborations between academia and industry to determine the relationships between the clinical, cognitive, imaging, genetic and biochemical biomarker characteristics of the entire spectrum of AD.
The goal of this clinical trial is to study the effects of dronabinol in US Veterans with agitation related to moderate to severe dementia. The main goals of the study are: - To evaluate the efficacy of dronabinol for the treatment of agitation in moderate to severe dementia compared to placebo - To evaluate the safety of dronabinol in the treatment of agitation in moderate to severe dementia compared to placebo Fifty (50) subjects will be given either dronabinol or placebo for 8 weeks. All subjects will then undergo a "washout" phase for 3 weeks, followed by the crossover intervention (i.e. subjects who received placebo during the first phase will receive dronabinol during the second phase, and vice versa). Thus, all participants will be taking dronabinol at some point during the study. During the study, subjects will undergo evaluations for: - Agitation - Cognitive changes - Physical changes (i.e. labs, ekg, physical exam)
Our study intends to offer 'real world' evidence of a viable, sustainable means to mobilize primary care via a comprehensive strategy for detecting cognitive impairment and dementias, advancing next steps for referral, and participating in the care planning and management of affected patients and caregivers. We will conduct a clinic-randomized, pragmatic trial testing the effectiveness and fidelity of our NIH Toolbox-derived paradigm to improve early detection and management of cognitive impairment/dementia in primary care settings serving health disparate patient populations.
Recent ground-breaking research has shown that clearance of toxic neuro-metabolites from the brain including the proteins β-Amyloid (Aβ) and tau that form dementia causing plaques and tangles is markedly impaired when sleep is disturbed. This suggests that dementia risk may be increased in people with sleep disorders such as obstructive sleep apnea (OSA). Longitudinal studies have linked OSA with a 70-85% increased risk for mild cognitive impairment and dementia. Despite this strong link, little is known about the OSA-specific mechanistic underpinnings. It is not fully understood as to how sleep disturbance in OSA inhibit brain glymphatic clearance. However, it is known that OSA inhibits slow wave sleep, profoundly activates sympathetic activity, and elevates blood pressure - particularly during sleep. These disturbances have, in turn, been shown to independently inhibit glymphatic function. Previous studies have attempted to sample human cerebrospinal fluid (CSF) involved in glymphatic clearance for dementia biomarkers during sleep. However, these studies were severely limited by the need for invasive CSF sampling. To address this problem, a set of newly available, highly sensitive blood based SIMOA assays will be used to study glymphatic function in people treated for severe OSA who undergo CPAP withdrawal. Furthermore, novel methods will be utilized to capture changes in slow wave sleep, blood pressure and brain blood flow together with sleep-wake changes in blood levels of excreted neuro-metabolites to define the pathophysiological mechanisms that inhibit brain cleaning in OSA.
