Filter by:This study is a feasibility randomised controlled trial (RCT) for an evidence-based intervention for people with moderate to severe dementia. The psychosocial intervention is adapted from Cognitive Stimulation Therapy (CST) and developed within the Medical Research Council (MRC) framework.
There are an increasing number of people in the U.S. with Alzheimer's disease and other dementias. Traumatic brain injuries (TBIs) are also common among both civilians and military personnel, and TBIs increase a person's risk for dementia. Providing care for a person with dementia is stressful. Dementia caregivers can experience difficulties including stress, depression, and reduced quality of life. Coordinated dementia care is known to benefit people with dementia and their caregivers. However, many caregivers do not have access to these supportive programs. Our project studies the benefits of telehealth as a new way for caregivers to receive coordinated dementia care services. We will offer 75 caregivers a 12-month caregiver support program delivered using telehealth (for example phones, tablets, computers). Caregivers of both Alzheimer's disease and TBI-related dementia will be included, and the program will be evaluated for effectiveness in both groups as well as in a control group. The information from our study will help improve quality of life for caregivers and individuals with dementia, including military members and Veterans. Our results will also help both civilian and military health professionals develop effective programs to support families living with dementia. Policy makers and organizational leaders can use the information to fund programs that best help families and communities facing dementia and TBI dementia.
These caregivers are a vulnerable group due to their physical isolation and well-documented rural disparities in health care access and quality. Many rural dementia caregivers experience serious health consequences due to caregiving responsibilities that can limit their ability to maintain their caregiving role. Thus, there is a pressing need for effective, scalable, and accessible programs to support rural dementia caregivers. Online programs offer a convenient and readily translatable option for program delivery because they can be accessed by caregivers in the home and at the convenience of the user. Building Better Caregivers is an online 6-week, interactive, small-group self-management, social support, and skills-building workshop developed for caregivers of individuals with Alzheimer's disease or related dementia. The investigators will conduct a hybrid effectiveness-implementation randomized controlled trial that will enroll and randomize 640 rural dementia caregivers into two groups: the intervention (workshop) group and the attention control group. Caregivers will be recruited throughout the United States. Primary outcomes will be caregiver stress and depression symptoms. The investigators hypothesize that stress scores and depression symptoms will be significantly improved at 12 months in the intervention group versus control group. The investigators will also identify key strengths (facilitators) and weaknesses (barriers) of workshop implementation. The investigators will use the RE-AIM implementation framework and a mixed methods approach to identify implementation characteristics pertinent to both caregivers and rural community organizations. If the Building Better Caregivers workshop is proven to be effective, this research has the potential to open new research horizons, particularly on how to reach and effectively support isolated dementia caregivers in rural areas with an intervention that is scalable, even in low-resourced settings. If the workshop can achieve its goals with rural dementia caregivers, some of those most isolated, it would also be expected to be scalable in other low-resourced settings (e.g., in urban or suburban environments).
There are very few effective interventions that promote functional independence in people with Alzheimer's disease (AD) and related dementias. This R21 project is the first step in the long-term goal of developing an effective, enjoyable, portable, and inexpensive non-immersive virtual reality (VR) training intervention for improving the performance of everyday tasks. The investigators' VR training approach is built upon the results of past studies that show 1) when people with AD repeatedly practice daily tasks they subsequently perform them more completely and without error; and 2) healthy people are able to transfer skills learned in VR-contexts to tasks in the real world. This R21 study will obtain preliminary data to inform a future randomized clinical trial through three aims: Aim 1) To test the hypothesis that individuals with mild-moderate AD will show improved performance on an everyday task after repeatedly practicing the task in a non-immersive VR setting; Aim 2) To explore usability and acceptability of the VR training as well as associations between individual differences variables (e.g., cognitive abilities, demographics) and training effects. To test Aim 1, 40 participants with mild to moderate AD will be recruited to complete daily VR Training sessions for one week. VR Training will include repeated practice of a single, everyday task in a non-immersive VR-context (VR Breakfast or VR Lunch; counterbalanced across participants). The primary outcome measure is performance of the real-life version of the trained task, which will be collected before and at two time points after training, compared to performance of an untrained, control task of comparable difficulty, and scored from video by coders blinded to training task/condition. To evaluate Aim 2, all participants and an informant will complete interviews and questionnaires and participants will complete tests of cognitive abilities. Usability and acceptability of the VR training will be evaluated and associations between participant variables and VR Training results will be explored. If the proposed hypothesis is supported and results show that training effects generalize from virtual to real tasks in the study sample, then VR training of custom and individualized tasks will be investigated in a future randomized, controlled clinical trial for maintaining and improving functional abilities in people with mild to moderate AD.
Difficulty completing everyday tasks is a primary reason for the high cost of care, loss of caregiver paid hours, and general caregiver burden associated with dementia. Electronic reminder applications hold promise as a low-cost solution to improve daily functioning, promote aging in place, and reduce caregiver burden and cost of care, particularly as older adults become more computer literate. There are many electronic reminders available for healthy individuals, but few have been developed to target the specific cognitive difficulties that impede completion of everyday tasks in people with dementia (i.e., premature decay of task goals, decreased motivation to perform tasks, distractibility, semantic knowledge degradation, etc.). Furthermore, there is a dearth of feasibility research on the fundamental efficacy and usability of reminder applications for people with dementia. This R21 proposal addresses these gaps with a feasibility study of the SmartPrompt, an enhanced electronic reminder aid designed for people with dementia that is used with an inexpensive smartphone. A diverse sample of older adults with mild dementia (N = 40) and their caregivers (N =40) will be trained to use the SmartPrompt and then asked to use the application to perform a target task (hydration, meals, or medication) twice per day in their homes for two weeks. Aim 1 will test the hypothesis that the SmartPrompt is effective at promoting everyday task completion (i.e., efficacy) relative to a one- week control period without the SmartPrompt. Using a single-group crossover design, efficacy outcomes will be obtained during the SmartPrompt and Control Conditions and will include participant and caregiver reports of task completion, caregiver report of burden, and participant report of frustration Aim 2 will investigate whether the SmartPrompt will be perceived favorably by participants and caregivers and the extent to which technical support is needed for its use (i.e., usability). Usability measures will be obtained from caregivers (report of technical problems, questionnaire), participants (questionnaire), the study team (training time, technical support required), and the smartphone (i.e., measures of smartphone use, response times to prompts). A third exploratory aim is to examine participant and caregiver features that are associated with efficacy and usability outcomes, including participant cognitive profile, participant/caregiver demographics, computer proficiency and self-efficacy, desire to change, etc. Results will be used to inform 1) a working model of barriers and facilitators for the use and efficacy of prompting applications that may be tested in future studies and 2) SmartPrompt design modifications for a future Phase II clinical trial.
This international study evaluates the impact of home-based caregiver-delivered music and reading interventions for people with dementia. The project aims to address the need for improved informal dementia care by training family caregivers to utilise a music or reading intervention with the person they are caring for. The interventions aim to decrease behavioural and psychological symptoms of dementia as well as improve quality of life and well being of both people living with dementia and their caregivers. Participants will be allocated into a music intervention group, a reading intervention group or standard care group. In addition, the researchers will seek to determine the cost-effectiveness of using the music intervention.
Agitation and aggression impose a tremendous burden on the individuals living with dementia, their families, caregivers, and healthcare systems. Neuropsychiatric symptoms of dementia (NPS) affect up to 80% of patients with Alzheimer's dementia (AD). The mechanisms of agitation in AD are poorly understood and the current interventions are only modestly effective while having serious adverse effects. In this study, the investigators propose to assess the mechanisms and treatment of neuropsychiatric symptoms in AD with the use of non-invasive, brain stimulation approaches. By applying magnetic stimulation to the surface of the head (transcranial magnetic stimulation - TMS) combined with electroencephalography (EEG), the investigators will be able to study the mechanisms of agitation and advance our understanding of AD. Further, the investigators will evaluate if transcranial direct current stimulation (tDCS) is effective to treat agitation dementia.
The purpose of the study is to evaluate the use of autologous Bone Marrow Derived Stem Cells (BMSC) as a means to improve cognitive impairment as occurs in Alzheimer's Disease and other dementias and to improve behavior and socialization issues which occur in adult Autism Spectrum Disorder. The use of Near Infrared Light, in conjunction with the use of BMSC, will also be assessed.
The Mexican American population in the U.S. is rapidly growing and aging. This project seeks to determine the prevalence and outcomes of cognitive impairment and dementia in Mexican Americans. It also seeks solutions to help patients with cognitive impairment and dementia and their caregivers get the resources they need.
To document effectiveness, safety, and tolerability of donepezil in patients with mixed AD/VaD, and to further document the effectiveness, safety, and tolerability of donepezil in patients with VaD. The effects of donepezil on executive functioning, behavior, general cognition, ADLs and global functioning will be assessed.
