Filter by:This research is being done to develop a unique matching process for caregivers of persons living with dementia, such as Alzheimer's disease, Lewy body dementia, frontotemporal degeneration, or other dementia syndromes. Dementia caregivers often assume greater caregiving burden than do non-dementia caregivers, and the caregiving duration tends to be longer. Many caregivers do not have the adequate support they need. Peer-to-peer support has been shown to improve quality of life, more engagement with services, improve caregiver health, and reduce hospitalizations in the person they are caring for. This study will help determine whether caregivers of persons with dementia would find a technology-based caregiver matching program valuable for the purpose of emotional support.
This is an international multi-centre cohort study of first and second degree family members of individuals who carry Frontotemporal Dementia (FTD) mutations in MAPT, GRN or C9ORF72 repeat expansions for youths between the ages 9-17.
This phase 2 is a randomized, double-blind, placebo controlled, 12 weeks study with daily oral administration of AZ-3102 aiming to evaluate the safety and pharmacokinetic (PK) profile in GM2 Gangliosidosis and Niemann-Pick type C disease (NP-C) patients. If approved by the country health authorities, a double-blind extension period will be proposed to the patients who complete the 12-week study.
The primary goal of this study is to test the hypothesis that oral nabilone treatment will reduce agitation compared with placebo in patients with Frontotemporal Dementia (both behavioural variant frontotemporal dementia and primary progressive aphasia). The study population is defined as patients with probable Frontotemporal Dementia that meet the International Psychogeriatric Association criteria for agitation in cognitive disorders.
Difficulties with speech and language are the first and most notable symptoms of primary progressive aphasia (PPA). While there is evidence that demonstrates positive effects of speech-language treatment for individuals with PPA who only speak one language (monolinguals), there is a significant need for investigating the effects of treatment that is optimized for bilingual speakers with PPA. This stage 2 efficacy clinical trial seeks to establish the effects of culturally and linguistically tailored speech-language interventions administered to bilingual individuals with PPA. The overall aim of the intervention component of this study is to establish the relationships between the bilingual experience (e.g., how often each language is used, how "strong" each language is) and treatment response of bilinguals with PPA. Specifically, the investigators will evaluate the benefits of tailored speech-language intervention administered in both languages to bilingual individuals with PPA (60 individuals will be recruited). The investigators will conduct an assessment before treatment, after treatment and at two follow-ups (6 and 12-months post-treatment) in both languages. When possible, a structural scan of the brain (magnetic resonance image) will be collected before treatment in order to identify if brain regions implicated in bilingualism are associated with response to treatment. In addition to the intervention described herein, 30 bilingual individuals with PPA will be recruited to complete behavioral cognitive-linguistic testing and will not receive intervention. Results will provide important knowledge about the neural mechanisms of language re-learning and will address how specific characteristics of bilingualism influence cognitive reserve and linguistic resilience in PPA.
Primary Progressive Aphasia (PPA) is a syndrome due to different neurodegenerative disorders selectively disrupting language functions. PPA specialist care is underdeveloped. There are very few specialists (neurologists, psychiatrists, neuropsychologists and speech therapists) and few hospitals- or community-based services dedicated to diagnosis and continuing care. Currently, healthcare systems struggle to provide adequate coverage of diagnostic services, and care is too often fragmented, uncoordinated, and unresponsive to the needs of people with PPA and their families. Recently attention has been gained by digital-health technologies, such immunoassay analyzer and high-field MRI, the most promising approaches to increase our understanding of neurodegeneration, and by new non-invasive brain stimulation techniques such as transcranial direct current stimulation (tDCS) that allow a personalized treatment approach. Our goal is to develop a new treatment approach in PPA in which the regional secondary care centers participating in this project should be the hub of a regional network. The MAINSTREAM (WP2- Efficacy of personalized training in the early stage of PPA) looks forward to introduce and evaluate therapeutic innovation such as tDCS coupled with language therapy in rehabilitation settings (WP2 Early Treatment). This objective will be pursued by conducting a randomized controlled pilot study in order to evaluate the efficacy of a combined treatment of Active (anodal) tDCS and individualized language training compared to Placebo tDCS combined with individualized language training in a subgroup of mild PPA defined using the Progressive Aphasia Severity Scale (PASS) (Sapolsky D, Domoto-Reilly K, Dickerson BCJA. Use of the Progressive Aphasia Severity Scale (PASS) in Monitoring Speech and Language Status in PPA. (2014) 28(8-9):993-1003).
Frontotemporal dementia (FTD), the most common dementia in individuals younger than 60 years of age, has no disease-modifying treatment. Neuroimaging studies have revealed salience and default mode network dysfunction, frontotemporal atrophy and hypometabolism as pathophysiological hallmarks of behavioral variant FTD (bvFTD). A key brain structure affected by bvFTD is the subgenual cingulate (SGC), which serves as a hub for multi-axonal projections to and from the ventromedial prefrontal, dorsal anterior cingulate, orbitofrontal, and dorsolateral frontal cortices, and limbic structures. The disruption of these SGC projections in bvFTD result in the core clinical features of apathy, disinhibition, loss of empathy, compulsivity, hyperorality and loss of executive function. The central goal of this proposal is to use deep brain stimulation (DBS) for modulation of the SGC downstream projections to treat bvFTD. Investigators hypothesize that SGC DBS will drive activity in the dysfunctional networks, reverse hypometabolism, and potentially improve symptoms. To determine the physiologic effects and mechanisms of SGC DBS, investigators will assess cerebral metabolism by FDG-PET, connectivity by rsfMRI and MEG, atrophy by volumetric MRI, and neurodegenerative and neuroinflammatory biomarkers. The safety and preliminary efficacy data obtained in these patients will inform the possible future role of DBS in apathetic bvFTD.
This study will evaluate evidence-based treatments for adults with mild Primary Progressive Aphasia (PPA). The aim of the study is to help identify efficacious communication and quality of life interventions for those with PPA and their care-partners. Participants with a diagnosis of PPA and their actively-engaged care partners will be involved in the study for 12 months. Each participant will receive a iPad equipped with the necessary applications and features for the study. Participants will complete evaluations, speech therapy sessions with a speech and language therapist, and sessions with a licensed social worker or related clinician. They will have access to Communication Bridge, a personalized web application to practice home exercises that reinforce treatment strategies. There are no costs to participate in this study.
This is an OLE study conducted to evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and clinical effects of WVE-004 in adult patients with ALS, FTD, or mixed ALS/FTD phenotype with a documented mutation in the C9orf72 gene. To participate in the study, patients must have successfully completed Phase 1b/2a WVE-004-001 study.
The Care Ecosystem is an accessible, remotely delivered team-based dementia care model, designed to add value for patients, providers and payers in complex organizational and reimbursement structures. Care is delivered via the phone and web by unlicensed Care Team Navigators, who are trained and supervised by a team of dementia specialists with nursing, social work, and pharmacy expertise. The evidence base to date suggests that the Care Ecosystem improves outcomes important to people with dementia, caregivers, and payers when delivered in a controlled research environment, including reduced emergency department visits, higher quality of life for patients, lower caregiver depression, and reduced potentially inappropriate medication use (Possin et al., 2019; Liu et al., 2022). The investigators propose a rapid pragmatic trial in 6 health systems currently offering the Care Ecosystem program in geographically and culturally diverse populations. The investigators will leverage technology, delivering care via the phone and web and using electronic health records to monitor quality improvements and evaluate outcomes while maximizing external validity. The investigators will evaluate the effectiveness of the Care Ecosystem on outcomes important to patients, caregivers, healthcare providers, and health systems during the pandemic. By evaluating the real-world effectiveness in diverse health systems that are already providing this model of care, this project will bridge the science-practice gap in dementia care during an unprecedented time of heightened strain on family caregivers, healthcare providers and health systems.
