Filter by:This study will explore the effect of ECT treatments plus usual care (ECT+UC) in reducing severe agitation in patients with moderate to severe dementia including Alzheimer's Disease, Vascular dementia, Frontotemporal dementia, and Dementia with Lewy Bodies. The study will also determine the tolerability/safety outcomes of ECT+UC.
Recent clinical data showed that patients with Alzheimer Disease (AD) might present epilepsy at early stages of the disease (Cretin et al., 2016, Vossel et al., 2016). In mice models of Alzheimer disease, preclinical researchers observed an increase of epileptic events during Rapid Eye Movement (REM) sleep, which is very unusual. This study aims at testing if patients with AD present an exacerbation of epileptic events during REM sleep, which could constitute an early biomarker of the disease. Investigators will evaluate the incidence of epilepsy during each sleep stage in 40 patients with early or moderate forms of AD and in 40 healthy subjects. Investigators will also look for a link between epilepsy during sleep in AD participants and memory performances, brain damage (by using MRI scans) and in the case of patients, the phenotype of the Apolipoprotein E(ApoE) gene.
This is a phase 2A multi-center, randomized, double blind, placebo-controlled, parallel group study of varoglutamstat, with a stage gate to phase 2B. In phase 2A there will be adaptive dosing evaluation of three dose levels with exposure to varoglutamstat or placebo for a minimum of 24 weeks, with preliminary evaluation of both cognitive function and pharmacodynamic changes on EEG spectral analysis in approximately 180 participants. In the event that the stage gate for phase 2B is reached, then phase 2B will assesses efficacy and longer-term safety in a larger study group, i.e., 414.
TriAL21 study is an interventional, open, one arm, prospective, national and single center study. A total of 200 patients with Down syndrome, aged 35 years and over, without diagnosis of Alzheimer's disease will be enrolled into the study. Participating centre is Institut Jérôme Lejeune; outpatient's clinic dedicated to treating patients with cognitive deficiencies of genetic origin including patients with Down syndrome.
Aims 1. To determine whether the 4 Mountains test of allocentric (i.e. viewpoint-independent) spatial memory, and tests of memory for a recent experience (e.g. watching a brief video), to diagnose the early stages of Alzheimer's disease. 2. We operationalise this as the ability of these tests to predict whether or not an individual progresses from having some cognitive difficulties (diagnosed as 'mild cognitive impairment' MCI) to subsequently developing Alzheimer's disease up to two years later. 3. To assess whether the ability to diagnose early stages of Alzheimer's disease can be improved by combining the scores from different memory tests, from questionnaires assessing spatial and social aspects of everyday life. 4. To assess whether scores on the spatial memory test are correlated with patients' reports of their everyday spatial memory, using a newly-developed questionnaire. Outcome Measures Primary study objective: To determine the ability of allocentric spatial and episodic memory test performance to predict progression from mild cognitive impairment (MCI) to Alzheimer's disease. Secondary outcome measure 1. To assess to what extent social characteristics of everyday life may impact upon progression from mild cognitive impairment (MCI) to Alzheimer's disease. 2. To correlate allocentric spatial test performance with real-world spatial ability as assessed through a novel spatial questionnaire.
This is a single blind, intention-to-treat, randomized controlled trial design to evaluate the feasibility and efficacy of a 12-week, evidence-based, individualized MEMORI Corps program delivered by trained older volunteers (n=80) to community-living PWD/CG dyads (n=240). Eligible PWD/CG dyads will be randomized to receive 12-weeks intervention group (n=120), or 12-week augmented waitlist control group (n=120) followed by 12-weeks of intervention. Eligible volunteers will be randomized to 12 months of MEMORI Corps active duty (n=40) where the participants will be matched to three families over the course of a year, or a 12-month augmented waitlist control group (n=40) followed by opportunity to serve 12 months active duty in MEMORI Corps. Program goals are to address unmet respite care needs for family caregivers, provide persons with dementia meaningful evidence-based activity programming, as well as provide health benefits, meaningful productive engagement, and peer support opportunities for senior volunteers.
Currently, the main treatment method for Alzheimer's disease (AD) is chemotherapy. However, the effectiveness of drugs is moderate and there are several side effects. In this clinical trial, the investigators would like to activate the brain by the transcranial ultrasound stimulation (TUS). This is a feasibility study to evaluate the safety and initial effectiveness of TUS for the treatment of patients with mild AD.
The RAATE proposal is designed to determine the effects of physical activity on risk factors for Alzheimer's Disease in older African American adults. The study will compare a physical activity program to an active control group. There are three main objectives of the protocol: 1) to determine if a physical activity intervention tailored to older African American adults is effective in modifying cognitive function associated with Alzheimer's Disease, 2) to determine if a physical activity intervention tailored to older African American adults is effective in modifying brain function and structure associated with Alzheimer's Disease, and 3) to determine if a physical activity promotion intervention tailored to African American adults is effective at enhancing physiological parameters. The primary endpoints for the study are episodic memory and executive functioning. The secondary outcomes include anthropometry, blood pressure, brain activation, cerebral blood flow, volume of whole brain and white matter hyperintensities, cardiorespiratory fitness, objectively measured physical activity, circulating hormones, and telomere length.
Alzheimer's Disease (AD) is characterized by amyloid-β (Aβ) plaque buildup and phosphorylated tau (p-tau) in the brain, as well as widespread neurodegeneration. Amyloid-β and tau are proteins that build up in the brain that may contribute to memory problems. The evidence suggests that both amyloid and tau play a critical role in AD and interventions that reliably and safely decrease the intracerebral burden of amyloid or tau could potentially be of marked clinical importance. Currently, therapeutic options are very limited and while there are pharmacologic interventions that transiently improve cognitive function, there are no treatments that alter disease progression. The purpose of this study is to see if multiple daily sessions of non-invasive brain stimulation can affect brain activity to decrease the amount of amyloid and tau in people with AD as compared to Sham (placebo) stimulation. The type of brain stimulation that will be used is called transcranial alternating current stimulation (tACS). This study will investigate different doses of tACS (2-4 weeks) and assess safety. The hope is that tACS will decrease the amount of amyloid and tau and improve memory and thinking in people with AD.
Physical activity and Alzheimer's disease (PAAD-2) is a randomized control trial that will assess the effects of exercise on middle-aged (40-65 years) cognitively normal adults who have a heightened risk of Alzheimer's disease (AD) due to family history (FH+). The investigators will also assess the extent to which this effect is moderated by apolipoprotein epsilon-4 (APOE4) carrier status, and will gather critical new experimental evidence on the use of physical activity to improve cognitive performance by persons at the greatest risk of Alzheimer's disease.
