Filter by:The proposed study is designed to evaluate the performance of the ALTOIDA™ System as a tool to assist physicians in diagnosing Alzheimer's Disease (AD) in real-world clinical settings. The design of this study is guided by two overriding factors: 1) to optimize the performance of the ALTOIDA™ Neuro Motor Index (NMI) prognosis classifiers, the subjects making up the training sets must be well characterized as to their clinical diagnosis, and 2) all ALTOIDA™ tests must be performed and reproduced in real-world clinical settings. Although there is already a large body of peer-reviewed scientific literature demonstrating that certain digital biomarker patterns are associated with certain neurologic conditions, the utilization of such tools for the evaluation of neurologic disorders is still considered an emerging science and therefore in the investigational stage. Although this protocol will report on brain patterns of certain neurologic conditions such as cognitive impairment and Alzheimer's disease, based on patterns published in peer-reviewed journals, such findings are not considered stand alone or diagnostic per se and should always be considered by the primary physician in conjunction with the patient's clinical condition. These data should only be used as additional information to add to the primary physician's diagnostic impression.
Data on prevention of perioperative neurocognitive disorders (pNCDs) are limited. The purpose of this monocentric parallel - grouped observational registry is to collect study data from studies with pNCDs as primary or secondary endpoint to estimate prevalence and incidence of pNCDs.
This study is to compare the safety and effects of donepezil (Aricept) for patients reporting cognitive or memory issues after receiving chemotherapy for breast cancer. Patients will receive either donepezil or placebo for 24 weeks. The primary objective is to see if memory improves with the use of donepezil during the study.
Phase III randomized controlled trial designed to test the effects of a 3-year intervention of the MIND diet (Mediterranean-DASH Intervention for Neurodegenerative Delay) on cognitive decline and brain neurodegeneration among 600 individuals 65+ years without cognitive impairment who are overweight and have suboptimal diets.
Cognitive rehabilitation is defined as a systematic functionally oriented intervention of therapeutic cognitive activities based on the assessment and understanding of patient's brain behavior deficits. This project focuses on restoring cognitive functions in order to understand the underlying deficits in the patient's brain by developing integrated cognitive rehabilitation scenarios in virtual reality that combine memory, attention and problem solving training with context specific motor movements.
This study evaluates the effects of physical exercise on cognition, functional status, brain atrophy and blood flow, and cerebrospinal fluid biomarkers of Alzheimer's disease in adults with a mild memory impairment. Half of participants will participate in a stretching-balance-range of motion exercise program, while the other half will participate in a moderate/high aerobic training program.
The proposed study aims to use 11C-acetate position emission tomography/computed tomography (PET/CT) to preliminarily test and validate methods for imaging astrocyte activation as an early indicator of neuroinflammation in Alzheimer's disease (AD). 11C-Acetate PET/CT has been shown to quantify astrocyte activation in vivo, but no reports have evaluated its potential in AD. The investigators propose to test 11C-Acetate PET/CT as a marker for astrocyte activation associated with pathologic amyloid deposition in AD. The investigators will compare binding between subjects with early stage AD and healthy controls. Further, the investigators will investigate the correlation between amyloid and acetate binding. If the investigators find increased astrocyte activation in response to cerebral amyloid by showing a group difference in brain acetate uptake between disease and controls or a strong correlation between acetate and amyloid PET/CT binding. Validating neuroinflammation markers in AD ultimately may guide therapeutic modulation of beneficial and damaging neuroinflammation to slow disease progression, as well as providing new insights into AD pathophysiology.
The proposed SYNERGIC trial is uniquely designed to evaluate the effect of aerobic and progressive resistance training exercises, combined with cognitive training and Vitamin D3 supplementation, in cognition and mobility in older adults with Mild Cognitive Impairment (MCI).
According to several reports, the oxidative stress and the nutrition could have an impact in the Alzheimer disease. The association of these two parameters measurements and the cognitive impairment decline could help in a predictive diagnosis of cognitive decline evolution in patients presenting cognitive disorders. This is a monocentric prospective "routine care" clinical trial on patients showing cognitive troubles especially memory complaints. The objective is to demonstrate a correlation between oxydative stress and nutrition biomarkers and the clinical evolution of patients complaining of cognitive impairments. The neuropsychologic data collection (the mini mental Status Examination (MMSE), the clock test, the Grober-Buschke test (FCSR-IR), the executive function evaluated by the Trail making test, and the medical imaging (by magnetic resonance imaging (MRI) or tomography in case of MRI contraindication) will be realized during the study inclusion phase in the usual intake of patients. Whole blood samples for the oxydative and nutrition biomarkers measurements will be taken at the study inclusion day during the stay at the Day hospital dedicated to the routine intake of patients issued from the memory consultation. In this study, the principal evaluation criteria will be the MMSE score evolution during the 60 months of the patients follow-up, measured during the routine visits scheduled approximately every 6 months, according to the french national authority for health recommendations. It will allow evaluating the correlation between the cognitive decline evolution measured by MMSE during the Alzheimer disease or related diseases method during the 2 years follow-up, and the oxydative stress blood markers.
This is a human clinical study involving the isolation of autologous bone marrow derived stem cells (BMSC) and transfer to the vascular system and inferior 1/3 of the nasal passages in order to determine if such a treatment will provide improvement in neurologic function for patients with certain neurologic conditions. http://mdstemcells.com/nest/
