In the current study, we will examine how daily paced breathing affects plasma amyloid beta levels and the rate of learning in older adults. Healthy adults aged 50-70 who meet all eligibility criteria will be invited to this study. Participants will be randomly assigned to one of the two conditions: 1) Daily memory and attention training followed by a paced breathing protocol designed to increase relaxation or 2) Daily memory and attention training followed by a paced breathing protocol to increase alertness. Participants will be asked to complete pre and post intervention cognitive testing online, engage in 10 weeks of daily brain training (starting Week 2) and 9 weeks of paced breathing (starting Week 3) at home. They will also be asked to come in for lab visits on Weeks 2, 7 and 12 to provide blood and urine samples to assess amyloid beta levels and to complete magnetic resonance imaging scans to assess perivascular space volume.
Spousal caregivers of Alzheimer's Dementia (AD) patients have an elevated risk of developing AD in the future. Past studies have shown the presence of serum indicators correlated with gut biome dysfunction in AD patients. We hypothesize that the same gut biome dysfunction may be present in spousal caregivers of AD patients.
Modifying health behaviors like physical activity level, diet, stress, and mental activity level can lower risk for Alzheimer's disease, but many middle-aged and older adults find it difficult to sustain health behavior changes over the long term. This project will develop a new intervention that educates people about Alzheimer's disease risk factors and helps them understand how their personal health beliefs may prevent them from making long-lasting lifestyle changes. The goal is to help people sustain health behavior changes to prevent or delay the onset of Alzheimer's disease and related dementias.
The goal of this pilot study is to improve the STAR-Caregivers Virtual Training & Follow-up (STAR-VTF) intervention for Latino caregivers of people living with dementia. The main objectives are to: (1) culturally adapt STAR-VTF online training modules, (2) pilot test Latino caregivers' responses to the adapted online training modules, and (3) develop an online survey to collect caregiver outcomes in a future study. Participants will receive the STAR-VTF intervention and asked to complete online surveys and participate in an exit interview to provide feedback on their experience.
The goal of this cohort study is to estimate the incidence of AD in the first-degree relatives of patients with AD. The main questions it aims to answer are: - cognitive changes of subjects at high risk of AD as ageing; - environmental and behavioral factors affecting AD incidence.
The goal of this clinical trial is to test the effects of different types of exercise on brain health and Alzheimer's risk in older African Americans. Specifically, the main question[s] it aims to answer are: - What is the effect of a Cardio-Dance Fitness (CDF) vs. a Strength, Flexibility, and Balance (SFB) intervention on a cognitive marker of Alzheimer's risk, generalization? - What is the effect of the CDF vs. SFB intervention on a fMRI biomarker of Alzheimer's, neural flexibility, and do improvements in neural flexibility mediate improvements in generalization? - Do ABCA7 genotypic variations moderate the efficacy of the CDF vs. SFB intervention for reducing Alzheimer's risk? Participants will undergo-- at baseline and post-test-- health assessments, cognitive tests, and structural and functional magnetic resonance imaging (fMRI), and a blood-draw to assess Alzheimer's risk biomarker levels.
The purpose of this research study is to investigate the effect of a light treatment on sleep, memory and brain function. In people with mild cognitive impairment (MCI) and Alzheimer's disease, sleep-wake disturbance is evident in up to 60% of patients. This can be caused by disruption of circadian rhythms and may affect our health and well-being. Circadian rhythms are the natural cycle of physical, mental, and behavior changes that the body goes through in a 24-hour cycle. Circadian rhythms are mostly affected by light and darkness and are controlled by a small area in the middle of the brain. They can affect sleep, body temperature, hormones, appetite, and other body functions. The circadian system plays an important role in the body and can affect sleep and brain function. The results of the research would help develop light-delivery methods to improve sleep and memory in patients with mild cognitive impairment (MCI) and Alzheimer's disease who typically spend a significant amount of time indoors.
The goal of this clinical trial is to demonstrate potential improvements in clinical trial methods relating to dementia and cognitive decline. The main questions it aims to answer are: - Can an intervention's outcome be better assessed by a latent variable ("δ") integrating cognitive performance with functional status? - Can latent biomarkers of δ guide the selection of an intervention that will modulate dementia severity? - Can a latent variable, derived from information collected remotely from caregivers, preselect subjects most likely to respond to the intervention? - Is the effect of the intervention in fact medicated by changes in the targeted biomarker? In this case, the biomarker will be a latent variable derived from several proteins measured in blood (i.e., so-called "adipokines"). The intervention will be donepezil, a medication approved for the treatment of Alzheimer's Disease, but only recently associated with adipokine changes. Participants with cognitive impairment and their caregivers will be interviewed by telephone and those with cognitive impairment will be treated for six-months with donepezil. On the basis of the caregiver's report, the cognitively impaired subjects will be assigned to two groups based on a prediction of their response to donepezil. Researchers will compare those groups to see if dementia severity, as measured by δ, improves in predicted responders, and whether the change in the d-score is mediated by changes in adipokines.
The purpose of this study is to see whether an adapted questionnaire called the Care Partner Hospital Assessment Tool (CHAT) for care partners of hospitalized patients living with Alzheimer's disease and related dementias (ADRD) (CHAT-AD) can help people with dementia receive better care after they go home from the hospital. Participants will be a care partner ('family member or friend') who provides unpaid care to a hospitalized adult relative or partner to help them take care of themselves because of dementia. Participants can expect to be in this study for 14 days.
