Filter by:There is a need for caregiver-initiated and -implemented non-pharmacological interventions directly to and for the person with dementia, including environmental assessment and modification, as first-line treatments for behavioral and psychological symptoms of dementia (BPSD) in persons living with dementia (PLWD). Delivered via telehealth, Harmony at HOME (H@H) aims to train caregivers of persons with moderate to severe ADRD in the skills of assessing and modifying the home environment to promote "person-environment fit," a concept that posits that the ability to access features within a built environment (e.g. bathroom, stairs,) or that factors within the environment itself (lighting, noise level, temperature), especially when linked with individualized social support, contribute to or even shape behavior. In addition to the intervention, the first 10 caregiver participants to enroll will also be invited to participate in two focus groups that will be facilitated during and after the intervention. The first focus group focuses on experiences as a dementia caregiver in rural areas. The second focus group focuses on providing feedback regarding caregivers' perceptions, acceptability, and usefulness of the H@H intervention. These focus groups will be conducted as structured interviews with open-ended questions that encourage participants to share their experiences.
This cluster randomized pragmatic clinical trial will test the effectiveness and feasibility of embedding the Tele-Savvy intervention, a psychoeducational program for family and other informal caregivers of older adults living in the community with Alzheimer's disease and related dementia (ADRD), in two health care systems/clinical sites: UConn Health in Farmington, Connecticut, and Emory Healthcare in Atlanta, Georgia.
A Phase 2a Open-Label Preliminary Safety, Tolerability, and Biomarker Study of Oral Fasudil in Patients with the 4-Repeat Tauopathies of Progressive Supranuclear Palsy-Richardson Syndrome or Corticobasal Syndrome
This is a non-interventional observational study designed to systematically record the results of routine laryngeal examinations and specific characteristics of dysphagia in patients with multiple system atrophy (MSA), Parkinson's disease (PD) and progressive supranuclear palsy (PSP) and related 4repeat tauopathies. The results of a fiberoptic / flexible endoscopic evaluation of swallowing (FEES) while performing a structured task protocol will be recorded. If available, laryngeal electromyography (EMG) results will also be recorded. In addition to the examination results, demographic and disease-specific data are collected, and two questionnaires, the Swallowing Disturbance Questionnaire for Parkinson's Disease (SDQ-PD) and the swallowing specific Quality Of Life Questionnaire (SWALQOL), are administered.
Parkinson's disease (PD) is one of the most common neurodegenerative disorders. The diagnosis of PD is primarily based on clinical presentations while the pathology stage of a-synuclein containing Lewy body deposition has already advanced. In addition to PD, there is another group of patients presenting with parkinsonism features mixed with other neurodegenerative symptoms. Pathologically, patients with these PD-mimicking parkinsonism syndromes, such as progressive supranuclear palsy (PSP), corticobasal degeneration disorders (CBGD) and frontotemporal dementia (FTD) with/without parkinsonism, have 4 repeat paired helical filament forms of tau protein (4R PHF-tau) aggregations in the neurons. Patients with these tauopathy related parkinsonism-plus syndromes could initially present as PD symptoms but will have a more deliberating disease course and combine with other systems degeneration. These patients are often a substantial diagnostic challenge to clinicians. Therefore, there is an urgent need to develop reliable imaging and biofluid biomarkers for differentiating patients with PD and variable parkinsonism-plus syndromes. Recently, new generation of novel radiotracer 18F-PMPBB3 (APN-1607), which can be labeled with 4R PHF-tau without significant off-target binding, has been successfully developed. Therefore, this study will enroll 150 participants, including 30 healthy controls, 30 PD patients, and 60 patients with different parkinsonism-plus syndromes (including 10 patients with multiple system atrophy, 10 patients with progressive supranuclear palsy, 10 patients with cortical basal syndrome and 30 patients with frontotemporal dementia), and 30 patients with mild cognitive decline (MCI) or Alzheimer's disease (AD). All participants will receive complete neurological examination, 18F-PMPBB3 (APN-1607) PET, brain MRI scans, plasma markers for total/phosphorylated tau, a-synuclein and Ab42/Ab40 and genetic markers covering MAPT、SNCA、LRRK2、GBA and APOE genes. We aim to explore: 1. Whether 18F-PMPBB3 (APN-1607) can differentiate patients with tauopathy (PSP, CBGD, FTD, MCI and AD) and synucleinopathy (PD, MSA). 2. Whether the distribution of tau deposition detected by 18F-PMPBB3 (APN-1607) correlate to disease severity, progression, and prognosis in patients with tauopathy. 3. Whether the loading of tau deposition detected by 18F-PMPBB3 (APN-1607) correlate to plasma levels of total/phosphorylated tau. 4. Determine specific genetic susceptibility sub-groups are more vulnerable to tau deposition detected by 18F-PMPBB3 (APN-1607) in patients with tauopathy. The research results will help to understand the potential of 18F-PMPBB3 (APN-1607) as an imaging biomarker for diagnosis, severity and therapeutic assessment tool for patients with tauopathy.
This study is a multicenter, double blind, randomized, placebo-controlled study to evaluate the safety, tolerability and immunogenicity of different doses, regimens and combinations of Tau targeted vaccines in participants with early Alzheimer's Disease.
Background and objects Amyloid plaques and tau protein are the landmarks of neurodegeneration in Alzheimer's disease (AD). On the other hand, it is reported that cerebral ischemia may induce amyloid plaques and tau protein accumulation. However, it was difficult to in vivo disentangle the complex and dynamic interactions between AD pathophysiology and cerebral vascular injury during the post-stroke cognitive impairment development in the past. With the advent of novel radiotracers specific to cerebral amyloid plaques and tau protein, we aim to conduct a prospective multimodal neuroimaging cohort study to investigate the contribution of vascular injury, amyloid plaque and tau protein to cognitive impairment. Subjects and methods The prospective project plans to recruit patients with vascular cognitive impairment (VCI) (Group A, n=80), Alzheimer's disease/mild cognitive impairment (MCI) (Group B, n = 120), fronto-temporal dementia (FTD) (Group C, n =30), and progressive supranuclear palsy (PSP) (Group E, n = 80). In addition, another 30 healthy people will be recruited as the control group (Group D, n=30). [18F]AV45 and [18F]MNI-958(PMPBB3) PET will be done for imaging cerebral amyloid plaque and tau protein distribution, brain MRI for obtaining structural and functional information, and neuropsychological tests for cognitive performance. Cognitive evaluation will be repeated 18 months after recruitment. In addition, APOE genotyping will be performed as well. By obtaining the neuroimaging information, such as severity of white matter change and infarction, cortical and hippocampal atrophy, and SUVRs of [18F]AV-45 and [18F]MNI-958(PMPBB3) PET, the study will be able to investigate the composite influence of cerebrovascular disease and neurodegenerative pathology on the trajectory of cognitive impairment. Group comparisons will be performed using the Chi-square test, independent t test, Mann-Whitney U test, ANOVA test, and multiple linear regression, where appropriate. Anticipation In this project, we will be able to explore the distribution patterns of amyloid plaque and tau protein among dementia patients with different etiologies, and also evaluate their influence on cognition
Alzheimer's disease (AD) is the most common cause of dementia and currently has no disease modifying treatments or simple accurate diagnostic tests. The goal of this project is to study how tau (a protein thought to cause AD) is made, transported and cleared in the human body. Better understanding of these processes may lead to improved understanding of AD, earlier diagnosis and a way to evaluate treatment.
This is an expanded access program (EAP) for eligible participants. This program is designed to provide access to ABBV-8E12 prior to approval by the local regulatory agency. Availability will depend on territory eligibility. Participating sites will be added as they apply for and are approved for the EAP. A medical doctor must decide whether the potential benefit outweighs the risk of receiving an investigational therapy based on the individual patient's medical history and program eligibility criteria.
