Active clinical trials for "Alzheimer Disease"

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.

This study will address the effectiveness of Family-centered Function Focused Care (Fam-FFC). Fam-FFC is a theoretically-based approach to care in which family caregivers partner with nurses to prevent functional decline and other complications related to hospitalization in older adults with Alzheimer's disease and related dementias. A systematic care pathway promotes information-sharing and decision-making that promotes physical activity, function, and cognitive stimulation during the hospitalization and immediate post-acute period. Our goal in this work is to establish a practical and effective way to optimize function and physical activity; decrease neuropsychiatric symptoms, delirium, and depression; prevent avoidable post-acute care dependency; and prevent unnecessary rehospitalizations and long-stay nursing home admissions, while mitigating family caregiver strain and burden.

Cerebral accumulation of tau and beta-amyloid are major factors of Alzheimer's disease pathology. A novel Positron Emission Tomography (PET) tracer (18-F-AV-1451) now offers the ability to study tau protein deposition in vivo in subjects, in which information on cerebral amyloid deposition has already been gathered. This enables to study effects of tau deposition on neuronal integrity, their relation to effects of beta-amyloid deposition and how this contributes to cognitive impairment or well-being in the elderly.

The overall aim of this study is to investigate how home dwelling people with early-stage dementia cope with their disease, explored through their participation in a 12-week health promotion course, through 3 sub-studies; 1) The users' experience in gaining information about dementia and meeting others in the same situation, 2) observation of the group interactions and support processes, and 3) investigate the effect of the 12-week health promotion course for people with early stage dementia on their cognitive function, psychosocial function and health behaviour.

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.

The purpose of the proposed study is to determine the feasibility of brief brain stimulation, using a device called Low Intensity Focused Ultrasound Pulsation (LIFUP), for persons with mild cognitive impairment (MCI) or mild (early-stage) Alzheimer's disease (AD). As a secondary aim, the investigators will explore whether this brief intervention is associated with improvements in cognitive functioning immediately and one week following the intervention. Subjects will be randomly assigned to one of two experimental groups: either the LIFUP administration will be designed to increase the activity of neurons in a certain part of the brain or decrease the activity of neurons. The investigators will study up to 8 subjects with MCI or mild AD. Initially, subjects will undergo a screening assessment with a study physician to determine medical and psychiatric history, establish AD diagnosis, and undergo a blood draw, if standard recent labs for dementia and EKG are unavailable. Subjects that meet criteria and agree to participate in the study will undergo a follow-up visit. In the baseline measurement visit, participants will first undergo neuropsychological testing. Participants will be randomly assigned to one of two LIFUP pulsing paradigms. Participants will then be administered four successive LIFUP treatments while the participants are in a functional magnetic resonance imaging (MRI). Sixty minutes following the administration, participants will undergo a second neuropsychological test. A final follow-up assessment will be administered at one week.

A study of the effects of Bacillus Calmette-Guérin (BCG) immunization on cerebrospinal fluid and blood-based biomarkers in older with mild cognitive impairment and mild-to-moderate to Alzheimer's disease.

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

The main purpose of this study is to evaluate the safety and tolerability of LY3372993 in participants with AD, non-Japanese, and Japanese healthy participants who are of first-generation Japanese origin. The study will also investigate how much LY3372993 gets into the bloodstream and will test the effects of LY3372993. The study will be conducted in two parts. The part A includes participants with AD and part B includes healthy participants. Participation could last up to about 61 weeks and may include up to 31 visits to the study center.

This is a randomized, pragmatic clinical trial to evaluate the effectiveness of a collaborative care-coordination program embedded in a health plan for people living with Alzheimer's disease and related dementias (ADRD) and their care partners versus usual care. The study population will include community-dwelling Medicare Advantage members living with ADRD and their care partners. Outcomes will be healthcare utilization outcomes of individuals with ADRD and include emergency department visits, outpatient visits, avoidable emergency department visits, and admission to long-term care facilities.
