Active clinical trials for "Memory Disorders"

Older women with cardiovascular disease (CVD) are at greater risk for memory loss, an important public health issue due to the negative effects to quality of life and health care costs. This research will be the first to examine the independent and combined effects of a lifestyle physical activity intervention and cognitive training on memory performance and memory-related serum biomarkers in this vulnerable population. The investigators will incorporate a practical lifestyle approach that can be delivered in the home and community settings to prevent or delay memory loss in older women with CVD.

The Alzheimer's disease or related disorders (ADRD) are among the most disabling diseases because of their main features such as cognitive impairment, loss of functional autonomy and behavioural disorders. In absence of current curative treatment, the identification of the predictive risk factors of progression of the disease, evaluated through its main symptoms, represents a major stake of public health. The Investigators aim at developing a regional database, which includes the patient medical records on a prospective basis, in collaboration with the medical and administrative staff and with the University hospital computer science departments. The main objective is to study the predictive factors associated with change in functional autonomy level, measured every 6 to 12 months in centres across Region Auvergne Rhone-Alpes in France. The real-life study population will consist in about 5400 patients with ADRD. The inclusion period will be of 3 years, the length of follow-up of each patient will be of 10 years max for a total study length of 13 years.

The goal of this clinical trial is to test 6 months of aerobic exercise in older adults who are 65 years or older and have mild cognitive impairment (MCI) or probable/possible mild Alzheimer's Disease. The main questions it aims to answer are: test the effects of aerobic exercise on aerobic fitness, white matter hyperintensity (WMH) volume, and patient-centered outcomes; identify the best exercise to improve aerobic fitness and reduce non-responses over 6 months; and examines the mechanisms of aerobic exercise's action on memory in older adults with early AD. Participants will receive 6 months of supervised exercise, undergo cognitive data collection and exercise testing 5 times over a year span, have an MRI brain scan 3 times over a one-year span, and have monthly follow-up discussions on health and wellness.

Many post COVID-19 patients suffer from cognitive deficits, even after 1 year after hospitalization. These complaints have a huge impact on psychological well-being and quality of life. In rehabilitation programs in the Netherlands, most interventions are based on physical therapy or learning how to cope with fatigue and low levels of energy. In former studies computerized training of cognition in other populations has been proven to be effective. Knowledge on the effect of computerized training on attention and working memory in patients suffering from COVID-19 is urgently needed, and may contribute to more evidence-based rehabilitation programs for these patients. Therefore the effectiveness of computerized training of attention and working memory in post COVID-19 patients with cognitive complaints will be studied in this study.

The proposed project is a fully embedded pragmatic trial (R01), following an R61 pilot collaboration with Lutheran Social Service of Minnesota (LSS-MN). For this project: a) the training program for Senior Companions that was developed in the R61 Phase will now be delivered as part of a routine onboarding process provided by LSS-MN to all senior support volunteers in half of their program regions across Minnesota; LSS-MN will offer the PorchLight Project program to all regions and volunteers in the state during the final months of the proposed NIA project, consistent with quality improvement approaches; and b) LSS-MN will administer regular surveys to volunteers, clients, and their proxies (e.g., family caregivers) as part of ongoing tracking and quality improvement efforts. The University of Minnesota investigators will not collect data nor administer training, as these activities will be fully integrated into the workflow of LSS-MN. UNIVERSITY OF MINNESOTA INVOLVEMENT: The University of Minnesota and collaborating investigators outside of LSS-MN will only 1) assist in survey item selection, 2) randomize the LSS-MN regions for the initial phases of the real-world trial for evaluation purposes, 3) analyze the de-identified data shared by LSS-MN, and 4) disseminate the project results in scientific, practice, and policy outlets/contexts.

This is an extension trial of a prior trial (NCT02213458). Both persons with dementia (PWD) and their caregivers were enrolled as dyads. The purpose of this randomized clinical trial is to evaluate the benefits of a program that supports model care for PWD and their caregivers. Whereas the prior trial only delivered care and examined outcomes up to 12-months, this trial extends care and outcome measurement for 5 years or until death, and includes all dyads where the caregiver reported high caregiver burden (Zarit-12 greater than or equal to 17) at pre-randomization baseline for the original trial. Participants were recruited from California, Nebraska and Iowa. Participants determined to be eligible were consented and randomized into one of two groups. Two thirds of dyads were enrolled into Navigated Care that provided them with phone-based assistance in meeting important benchmarks in their care, for example completion of legal and financial planning and strategies for minimizing caregiver burden. One third of dyads were enrolled to a control group, entitled Survey of Care. Outcomes were unchanged from the original trial except for the addition of time to long term care placement and are detailed below.

The ability to find one's way in the world is known as wayfinding. Many older adults who live in senior communities, such as independent living and assisted living residences, find wayfinding very challenging. Often times, these communities are not designed in a way that helps people find their way very easily. When people cannot find their way, they can get lost, be dependent upon others for getting out and about, or even be afraid to leave their rooms. The purpose of this study is to find out if distinctive signs and decorative elements, along with a special type of education called Spaced-Retrieval education, help residents in these communities find their way more effectively. Twelve senior communities will be assigned by chance to one of three conditions, including: 1) control - no change (the community stays the same); 2) signs and decorative elements enhanced; and 3) signs, decorative elements, and special education added. After agreeing to be in the study, the participants will be asked to find their way to certain places in their community four times over a year. Some people will be asked to participate in educational sessions on wayfinding. In addition, some people will be asked to wear a location tracker, (like a fitness tracker), for four weeks during the year. How well people find their way, along with how much they travel about within the communities, will be compared between the three groups. It is hypothesized that those in the communities with special signs and decorative elements will find their way more effectively than those in the control communities. It is also hypothesized that participants in the communities with the special education intervention will find their way better than those without the education. Finally, it is hypothesized that participants in the communities with signs and cues and education will travel about further distances than those in the control communities. The results of the study can help people who have a tendency to get lost find their way more effectively in their community, and this could result in more independence.

Hippocampus and medial temporal lobe (MTL)-dependent memory is impacted by a wide range of psychiatric and neurologic conditions. These cognitive limitations often result in limited functional abilities for patients. Currently available pharmacologic and behavioral treatments are somewhat controversial and have minimal evidence-based effectiveness. Recently, deep brain stimulation was used to modulate MTL activity and subsequently improve memory performance. However, such implantable devices require neurosurgery with major associated health risk. At present, there are no publications reporting non-invasive neurostimulation targeting MTL regions to improve memory. The central hypothesis of this project is that non-invasive, low intensity focused ultrasound pulsation (LIFUP) can selectively increase regional MTL activity and thus be used as a cognitive neural prosthetic capable of improving memory performance. The aims of this study focus on whether LIFUP can increased blood oxygen level dependent (BOLD) activation in the entorhinal cortex and functionally associated regions, whether this increased activation is greater using short train or long train LIFUP parameters, and whether this LIFUP-induced activation, when applied during learning, results in improved memory.

The proposed project aims to systematically examine the feasibility of remote, caregiver-led tACS for older adults who are vulnerable to memory decline.

The purpose of this study is to test the effect of a cocoa-derived dietary flavanol on brain structures and cognitive outcomes in a 12-week randomized controlled trial of 146 healthy participants, age 50-69, who will receive this cocoa derivative or a placebo. Th investigators will also examine the role of inflammation in this relationship.
