Active clinical trials for "Dementia"

Pilot study to evaluate the feasibility of a pilot embedded pragmatic cluster randomized controlled trial to reduce the duration of antibiotic therapy and number of antibiotic prescriptions in nursing home residents with AD/ADRD.

PLUG Dementia Trial: Patients will be screened at Intermountain Medical Center and at Intermountain affiliated anticoagulation clinics in the Salt Lake City region. Patients with atrial fibrillation that undergo a standard of care, clinically approved, left atrial appendage closure will be considered for study. All patients will be followed for 24 months, and will be assessed at the 3-, 6-, 12-, 18- and 24-months post-left atrial appendage closure as well as other visits deemed necessary for clinical care. All subjects will undergo protocol-specified laboratory tests and will complete 6 standard, validated questionnaires at each follow-up visit, except at the 3-month visit when only one questionnaire will be administered. A subset of patients (n=20), will receive a cranial MRI at baseline and 24-month visit. MRI PLUG Dementia Sub-Study: In addition to the above, 20 of the 60 subjects who are selected for participation in this sub-study will receive a cranial MRI at baseline and at the 2-year (24 months) follow-up visit.

The purpose of this project is to study brain imaging of a substance called tau, which is found in brains of persons with Alzheimer's disease, using the Tau binder, 18F-THK-5351, for live imaging of tau in the brain. The main goal of this proposal is to study whether diabetes status (type 2 diabetes [referred to as diabetes] and pre-diabetes, compared with normal glucose tolerance [NGT]), is associated with increased tau accumulation in the brain, one of the culprits of Alzheimer's disease, in a community-based group of middle aged Caribbean-Hispanics with a mean age of 63 years. The investigators propose to conduct tau positron emission tomography (PET) imaging in 30 middle aged Hispanics.

This is a feasibility/pilot, prospective cohort study to determine how to implement and refine Outreach-ER intervention for a larger clinical study. A key feature of Outreach-ER is to reach out to people living with dementia (PLWD) and their families following an emergency room visit or hospitalization. The outcome of this study will help in the overall goal of studying the impact of Outreach-ER in a larger clinical study and focus on outcomes relevant to PLWD and their care partners.

The purpose of this research study is to evaluate tau distribution in the brain of subjects with: FTD caused by different genetic mutations, any mutation carriers (with or without symptoms), any non-mutation carrier, any sporadic FTD, normal controls.

The purpose of this study is to estimate how quickly cognitive status and functional status in older patients on hemodialysis declines.

Amyotrophic lateral sclerosis (ALS) with frontotemporal dementia (FTD) is a rare clinical entity, in which both disorders are variably associated in the same patient or within the family. This adult-onset disorder, which is rapidly fatal, occurs in some families with autosomal dominant (AD) transmission and age-dependant penetrance. Two studies have provided evidence for linkage of this condition to chromosomes 15 (in a single family) and 9 (in five families). However, none of these loci have been yet confirmed. Through a national network of 10 centres with specialists for FTD and/or ALS, we have identified 35 probands with ALS-FTD, including 13 with a family history consistent with AD inheritance. Mutations in the SOD1 and tau genes, respectively responsible for autosomal dominant forms of ALS and FTD, will be excluded by direct sequencing. We will then extend the pedigree of the 13 autosomal dominant families to all consenting first, second and eventually third degree relatives, using well defined criteria for FTD and ALS. The same strategy will be applied to newly identified families during the course of the project (at least, seven families with AD inheritance expected). Linkage studies will be performed in the 20 families using markers from the two candidate regions on chromosomes 9 and 15. Then, refinement of the candidate region will be obtained by analyzing the linked families with a high density of microsatellite markers. This should lead to the refinement of the candidate regions, allowing to search for mutations in candidate genes. Genes located within the critical regions will be prioritized for their analysis by sequencing, according to their expression in the nervous system and to their function. Once the responsible gene(s) will be identified, it will then possible to define its spectrum of mutations and to establish genotype/phenotype correlations. Alternatively, if none of the candidate regions is confirmed, a genome wide search will be performed, allowing to identify one or more loci for ALS-FTD. The same strategy would then be applied to identify the corresponding gene(s). This project should contribute for identifying the molecular basis of this devastating disorder with practical consequences for genetic counselling in ALS-FTD families, and with the perspective of elucidating the pathophysiology of this disorder.

The Cognitive Neuroscience Section of the National Institute of Neurological Disorders and Stroke proposes to continue its cross-sectional and longitudinal studies of cerebral metabolism in frontal lobe dementias and atypical basal ganglia disorders. These studies include repeated assessments of neuropsychological and brain anatomical and metabolic function in subjects with these important and possibly related brain disorders.

The growing number of persons with dementia (PWDs) calls for policy changes and service innovation. Recent case management (CM) research is recognized by its positive impacts on family caregivers (FCGs) of PWDs. However, research gaps are identified, including the paucity of theoretical based CM practice and a lack of mediator effects. Therefore, the original purpose of this five-year project was to implement a theoretical-based randomized controlled CM intervention for FCGs of early to moderate PWDs at home based on a stress model and tailor to needs prioritized by FCGs. This project was funded by the Minister of Scientific and Technology for the first two years and accomplished the first two aims: 1. First year: to develop and test the psychometric properties of related instruments and protocol (cross-sectional study); 2. Second year: to conduct a feasibility test for the CM intervention (a pilot RCT). The purpose of the current project is to achieve aim 3 (three years): to implement a 4-month CM intervention (the main RCT). In total, there will be 2 home visits, 2 phone calls to the dyads, and receiving telephone calls from the FCGs during the working hours. Investigator will collect 4-time point data at T0 for base line data, T1 (after the recruitment, 4 th month, the first follow up), T2 (after the recruitment, 6th month, the second follow up) and T3 (after the recruitment,12 th month). Investigator will recruit 76 dyads in three years (38 dyads for each group)(n = 152 in total). The primary outcomes are FCG QoL and PWD behavioral problems, while the secondary outcome is the percentages of PWD status (i.g. nursing home admission) and the frequency of PWD acute hospitalization. Investigator will also test of mediator effect of FCG self efficacy using statistical analysis method such as Hierarchical Linear Modeling (HLM).

We want to determine if patients with dementia show any kind of emotion while they look at a defined selection of photos. These are photos taken from a international image-platform and mixed with photos (biographic) that show personal objects, personal events, etc. While the photos will be presented each a few seconds the skin conductance and the heart rate will be measured. We want to find out if there is any emotion measurable while showing the photos.
