The Swedish BioFINDER 2 Study
DementiaAlzheimer Disease10 moreThe Swedish BioFINDER 2 study is a new study that will launch in 2017 and extends the previous cohorts of BioFINDER 1 study (www.biofinder.se). BioFINDER 1 is used e.g. to characterize the role of beta-amyloid pathology in early diagnosis of Alzheimer's disease (AD) using amyloid-PET (18F-Flutemetamol) and Aβ analysis in cerebrospinal fluid samples. The BioFINDER 1 study has resulted in more than 40 publications during the last three years, many in high impact journals, and some the of the results have already had important implications for the diagnostic work-up patients with AD in the clinical routine practice. The original BioFINDER 1 cohort started to include participants in 2008. Since then there has been a rapid development of biochemical and neuroimaging technologies which enable novel ways to the study biological processes involved in Alzheimer's disease in living people. There has also been a growing interest in the earliest stages of AD and other neurodegenerative diseases. With the advent of new tau-PET tracers there is now an opportunity to elucidate the role of tau pathology in the pathogenesis of AD and other tauopathies. The Swedish BioFINDER 2 study has been designed to complement the BioFINDER 1 study and to e.g. address issues regarding the role of tau pathology in different dementias and in preclinical stages of different dementia diseases. Further, the clinical assessments and MRI methods have been further optimized compared to BioFINDER 1.
GENetic Fronto Temporal Dementia Initiative in Lille
Frontotemporal DementiaGENFI Lille is a French cohort that belongs to the international initiative GENFI2, a five year longitudinal biomarker cohort study of genetic FTD and its associated disorders (including MND/ALS) investigating members of families with a known mutation in GRN or MAPT or an expansion in C9orf72 (including those affected with the disorder as well as at-risk members of families).
Longitudinal Multi-Modality Imaging in Progressive Apraxia of Speech
PPANon-fluent Aphasia3 moreThe study is designed to determine the relationship between structural and functional changes in the brain on imaging and progression of speech and language, neurological and neuropsychological features in patients with neurodegenerative apraxia of speech (AOS).
First-in-Human Evaluation of an Astrocytic Glutamate Transporter (EAAT2) PET Tracer in Dementia...
Alzheimer DiseaseFrontotemporal Dementia1 moreThis is a first in human study that will assess the safety and diagnostic performance of [18F]RP-115 (fluorine-18 labeled RP115), a positron emission tomography (PET) agent. This agent has the potential to identify the early changes that occur in the brains of patients with Alzheimer's disease (AD) and frontotemporal dementia (FTD).
Tau PET Imaging in Atypical Dementias
Primary Progressive Aphasia With Suspected Alzheimer's DiseaseThe goal of this study is to demonstrate the feasibility of mapping tau pathology in subjects with Primary Progressive Aphasia, using PET protocol with F-AV-1451 (trade name AV-1451) and to systematically document the extent and location of tau pathology in PPA patients in vivo using the same techniques.
HDtDCS in Logopenic Variant PPA: Effects on Language and Neural Mechanisms
Primary Progressive AphasiaThis study aims to evaluate the effectiveness of a therapy called High-Definition Transcranial Direct Current Stimulation (HD-tDCS) for the treatment of the language deficits experienced by people with a type of Primary Progressive Aphasia. This study uses a combination of brain imaging, language assessment, language training sessions, and HD-tDCS therapy as well as placebo therapy sessions.
Transmagnetic Stimulation Pilot in Primary Progressive Aphasia
Primary Progressive AphasiaFrontotemporal degeneration (FTD) is a non-Alzheimer's dementia that is the 2nd most common cause of dementia in the United States. FTD may present with focal language symptoms that are clinically described as primary progressive aphasia (PPA). There are two types of PPA associated with FTD-semantic variant primary progressive aphasia (SV-PPA) and nonfluent/agrammatic variant primary progressive aphasia (NFV-PPA). Both diseases are progressive neurodegenerative disease processes that compromise dominant hemisphere large scale brain network function, ultimately resulting in mutism. There are currently no FDA-approved treatments for PPA and management is mostly supportive. In combination with resting state functional MRI (rs-fMRI), transcranial magnetic stimulation (TMS) with intermittent theta burst stimulation (iTBS) offers a non-invasive alternative to pharmacotherapy in persons with PPA. In our prior studies of Alzheimer's disease (AD) and Lewy body Dementia (LBD) subjects, investigators have determined that the anterior temporal pole (area TGd and TGv) is an area that is commonly dysfunctional in dementia. The investigators have already embarked upon an fMRI guided study of iTBS in early stage Alzheimer's disease where subjects received a series of 5 treatments to distinct brain regions inclusive of area TGd. The investigators propose a case study of 3 PPA studies where rs-fMRI is applied to the large-scale language networks.
The Care Ecosystem Consortium Effectiveness Study
DementiaDementia4 moreThe 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.
Palmitoylethanolamide Combined With Luteoline in Frontotemporal Dementia Patients. A Randomized...
Frontotemporal DementiaFrontotemporal dementia (FTD) is a devastating neurodegenerative disorder. It is the second most frequent cause of presenile neurodegenerative dementia in those less than 65 years of age. Currently, there is no effective pharmacological treatment to slow down the progression of FTD. Recently, it has been proposed that neuroinflammation could be involved in specific forms of FTD and that novel drugs targeting neuroinflammation could potentially be useful in FTD treatment. An available form of ultra-micronized PEA combined with luteoline (PEA-LUT) has gained attention for its proven anti-inflammatory and neuroprotective properties reported in neurodegenerative conditions related to FTD, such as Amyotrophic Lateral Sclerosis. The administration of PEA-LUT treatment may have a clinical impact in behavioural variant FTD (bv-FTD) patients. In particular, PEA-LUT treatment could be able to reduce behavioural disturbances, the more disabling symptoms in bv-FTD, with a related improvement of daily living activities of affected people. Moreover, a multimodal approach (cognitive/neurophysiological) can be used to assess the brain correlates related to the clinical improvement associated with PEA-LUT treatment, thus making remarkable strides in understanding how FTD affects the brain. Potentially the proposed project could provide a valid treatment for cognitive and behavioural dysfunction in FTD patients, with consistent impact for the National Health Systems and minimum cost for the patients.
