Filter by:This study will assess the effects of VX-745 on markers of disease in the central nervous system of patients with MCI due to AD or with mild AD. The study will also evaluate the safety and tolerability of VX-745 in these patients during 6 weeks of dosing, as well as the plasma and cerebrospinal fluid concentrations of VX-745 during dosing.
This study will assess the effects of administration of VX-745 for 12 weeks on amyloid plaque burden in Alzheimer's disease (AD). Subjects who meet entry criteria will undergo 11C-PiB (Carbon-11-labeled Pittsburgh Compound B) positron emission tomography (PET) at baseline and after 45 days of dosing with VX-745. Cognitive testing will also be conducted at baseline and day 45.
The Imaging Dementia-Evidence for Amyloid Scanning (IDEAS) Study will establish an open-label, longitudinal cohort study to assess the impact of amyloid PET on patient outcomes. The study will be performed in accordance with the Center for Medicare & Medicaid Services (CMS) policy of Coverage with Evidence Development (CED) in Medicare beneficiaries who meet the Appropriate Use Criteria (AUC) for amyloid PET (Johnson et al. 2013). Our hypothesis is that amyloid PET will decrease uncertainty and increase confidence in the underlying cause of cognitive impairment, that this will translate into earlier counseling and interventions in these domains, and that these interventions will lead to improved outcomes.
This is a pilot study to test the efficacy of repetitive transcranial magnetic stimulation (rTMS) on cognitive improvement in individuals with mild cognitive impairment (MCI). The main objective of this study is to investigate the ability of rTMS to produce cognitive improvement in individuals with MCI. A secondary objective is to determine whether individuals with MCI following mild brain trauma respond differently to rTMS treatment compared to individuals with non-trauma related MCI. Participants will undergo both active and sham (placebo) rTMS treatment. Cognitive and psychological assessments will be administered before and after each week of rTMS therapy, for both active and sham conditions. Cognitive testing will include verbal, semantic, logic, visual, conceptual, and memory tasks.
Diabetes( mainly type II diabetes )lead to the central nervous system (CNS) function impairment, especially the mild cognitive impairment that increased the risk of progression to dementia.The primary objectives are defined according to a hierarchical design: i) to tailor and apply multi-parametric, functional MRI techniques to identify cerebral abnormalities (cerebral biomarkers) in type 2 diabetes mellitus and prodromal diabetes mellitus ; ii) to assess whether these cerebral biomarkers are associated with cognitive decrements;iii) to follow up with the putative prediabetic condition patients to verify whether they can transform into diabetes.
Post operative cognitive dysfunction (POCD) is recognized as a frequent complication after both cardiac and non cardiac surgery, affecting approximately 1/3 of the patients. The aim of this study is to examine the possible effect of the novel reversal agent sugammadex versus neostigmine/ atropine combination on cognitive function of adult patients after elective surgery during the early post operative period as well as at discharge.
The study involves a novel Virtual Reality Interface that offers full-body immersion "Alterniity AR" and more specifically computer exercises blended with game activities. It was hypothesized that "Alterniity AR" facilitated, game blended cognitive and/or physical exercise improves global cognition when compared to control groups; moreover, these improvements may be manifested by brain activity changes. The investigators explore here the impact of potential moderators on combined exercise-induced cognitive benefits, as well as, individual/separate training schemes. In addition, the proposed study will provide Alterniity AR" in a closed feedback loop with a direct, reliable, and non-invasive method for assessing changes in brain activity associated with elderly in risk of dementia. The paradigm for the current study will combine neurophysiological knowledge with mathematical signal processing and pattern recognition methods to temporally and spatially map brain function, connectivity and synchronization.
Healthy aging is associated with a decline in multiple cognitive domains, as well as motor control function. The long-term consequences of cognitive and functional impairment resulting from age-related cognitive decline are well documented in the scientific and clinical literature, with significant evidence of related problems with independent functional abilities. This study aims to understand how the experimental computer program can affect cognition and attention in participants with age-related cognitive decline.
The daily routine in clinical settings often showed cognitive impairments in patients with congestive heart failure, particularly in terms of executive functions, episodic memory, perceptual speed and attention. It is assumed that cognitive impairments in patients with congestive heart failure may lead to deficits in medication-adherence and self-care abilities, resulting in increased healthcare costs. Recent studies reported performance improvements after cognitive training that transferred to new, untrained tasks and abilities in healthy subjects across a wide range of ages. This study investigates the effects of cognitive training in patients with congestive heart failure.
Elderberries (Sambuci fructus) have been shown in a number of studies to have significant anti-inflammatory and antioxidant effects. Multiple human and animal studies have supported the anti-inflammatory and antioxidant effects of elderberry preparations and it has been used in natural medicine for hundreds of years. Studies examining factors that may decrease the risk of Alzheimer's disease have revealed that drinking juices with similar properties to elderberries is one of the most reliable way to decrease risk. As such the investigators wish to determine the effects of elderberry juice on cognitive decline in a group of subjects at high risk for Alzheimer's disease, those with mild cognitive impairment. Elderberry juice is a commercially available nutritional supplement and easily available to this population.
