Filter by:The goal of this study is to test the efficacy of a mealtime intervention in respite care centers for people with dementia and their caregivers. Mealtimes become more challenging as dementia progresses causing nutritional and behavioral issues in the affected individuals. Using a train-the-trainer program built on the Partners at Meals model, volunteers in respite centers partner with caregivers and develop a mealtime plan that builds on the strengths of the person with dementia, and develop a supportive environment for change. A tele-health component is involved in the communication between the respite center volunteers/staff and families. Recruitment is limited to people attending the particular respite centers.
To evaluate the superiority of brexpiprazole 1 mg or 2 mg over placebo after a 10-week treatment regimen for agitation associated with dementia of the Alzheimer's type in patients who require medication, and to investigate the safety of brexpiprazole and identify the optimum dose.
Carrying the APOE ɛ4 allele is the strongest genetic risk factor for developing Alzheimer's disease. The goal of this project is to identify whether carrying the APOE ɛ4 allele is associated with reduced delivery of DHA to the brain. This information will help us identify the target population that could benefit from DHA supplementation to prevent cognitive decline.
To investigate the treatment effect of theta-burst transcranial magnetic stimulation on Alzheimer patients, and the underlying neural mechanism by MRI.
This placebo-controlled, double blind study evaluates the treatment effects of adding a multi-pathway botanical dietary supplement (ReBuilder) to the standard treatment regimens of subjects diagnosed with mild or moderate stage Alzheimer's Disease. The objective of the study is to determine if mild and moderate AD patients exhibit improved or stabilized cognitive function when this supplement is added to maximum tolerated doses of their standard treatments.
Preclinical models suggest that riluzole, the active metabolite of BHV-4157, may protect from AD-related pathology and cognitive dysfunction. Titrated dose of BHV-4157 to 280 mg, or placebo, were administered orally once daily. Duration of treatment is 48 weeks in double-blind phase. There is also a screening period of up to 42 days; and a 4-week post-treatment observation period. Eligible participants who completed the double-blind treatment phase had the opportunity to receive open-label troriluzole for up to 48 weeks in an open-label extension (OLE) phase.
Alzheimer's disease and related dementia (ADRD) is one of the most challenging chronic health conditions in the United States and considerable disparities exist in the diagnosis and prevalence of ADRD among communities of color. Research suggests that ADRD caregiver interventions have demonstrated efficacy, however, it remains unknown whether existing ADRD caregiver interventions are useful or accessible to African American ADRD caregivers in community settings. The primary goal of the proposed project is to develop an in-home psychoeducational intervention (The Senior Companion Program Plus, or SCP Plus) that is accessible, sustainable, and affordable for African American ADRD caregivers. The SCP Plus will focus on African American ADRD caregivers who are particularly affected by poverty, discrimination, and barriers to health care services and supports. A recent pilot study has established the feasibility and utility of SCP Plus. With the assistance of 6 student research assistants over the course of the project, we will implement the SCP Plus at sites in Texas, Louisiana, and Arkansas, recruiting approximately 114 participants. The participants will be randomized with 57 caregivers receiving the SCP Plus and 57 caregivers receiving services as usual with the Senior Companion Program. A weekly, 60 minute psychoeducational module will be delivered face-to-face across 9 weeks and will focus on education about ADRD, behavior management, communication skills, and aspects of providing care that enhance meaning such as spirituality. In order to provide an accessible and cost effective intervention that is potentially sustainable, senior companions will be trained to provide the intervention in the homes of the African American ADRD caregivers. Specific Aim 1. Determine whether SCP Plus reduces level of burden and stress among African American caregivers over a 3- and 6-month period when compared to a usual care control group. Specific Aim 2. Ascertain if SCP Plus improves coping skills among African American caregivers over a 3- and 6-month period when compared to a usual care control group. Specific Aim 3. Examine whether SCP Plus improves the level of satisfaction with support social among African American caregivers over a 3- and 6- month period when compared to a usual care control group. Specific Aim 4. Explore and interpret the statistical results obtained in the first quantitative phase to help explain why participants who scored in the lower and upper quartiles on caregiver burden/stress were impacted or not by the usefulness of the intervention. Successful design, delivery, and evaluation of the SCP Plus will lead to a cost effective, sustainable, and accessible intervention that can be implemented in other Senior Companion programs across the country, thus maximizing its impact as a community-based program to address the needs of African American ADRD caregivers.
The goal of this project is to determine whether low doses of ionizing radiation (LDIR) from repeat CT scanning improves function, cognition and/or behavior in severe AD.
Active treatment extension study of the 331-14-213 trial, to assess the long-term safety and tolerability of oral brexpiprazole as treatment in adult participants with agitation associated with dementia of the Alzheimer's type (AAD).
This research project will address a desperate need for evidence on how diet could be used to treat and improve symptoms of Alzheimer's disease (AD). It has been estimated that 36 million people have dementia worldwide, and in older people Alzheimer's disease accounts for 60-70% of all dementia. Research supports the hypothesis that modifiable lifestyle-related factors are associated with cognitive decline, which opens new avenues for prevention or modification of disease. The concept that inspires this proposal 'Ageing-Gut-Brain Interactions study' is that the gut microbiota impact upon the gut-brain axis and thereby on behaviour, including challenging behaviours often associated with dementia. In the absence of available cures for Alzheimer's disease, diet is an important modifiable component but knowledge about the role of diet in clinical symptoms of dementia is currently very limited. A recent study from Ireland from the European Union funded Nu-Age cohort reported that the gut microbiota profile in the elderly was different between community-living and institutionalized individuals, with specific microbiome profiles correlating with frailty and poor health. Changes in dietary composition and diversity were considered the main drivers of the shifts in gut bacteria profile. In this multi-disciplinary research study, the investigators will assess the gut microbiota composition in people with Alzheimer's dementia with and without challenging behaviours; test the feasibility of recruitment; and provide initial data to support a future grant application involving a dietary intervention study in patients with Alzheimer's disease. The investigators will test the hypothesis that the gut-brain axis promotes behavioural changes in Alzheimer's dementia and is responsive to changes in gut microbiota profile, by comparing the gut microbiota profile between three participant groups (1) Alzheimer's dementia with challenging behaviour, (2) Alzheimer's dementia without challenging behaviour, and (3) a control group of healthy age-matched elderly. The investigators will also carry out a survey of care homes to assess willingness to participate in a future dietary supplementation study.
