Filter by:This study is being done to research the usefulness of PET/CT imaging for measuring brain inflammation and its relation to Alzheimer's Disease. Additionally, researchers as looking to learn more about the side effects of a new radioactive tracer (radiotracer) C-11 ER176.
This study is being done to evaluate the safety and feasibility of using Dasatinib and Quercetin together in subjects with Mild Cognitive Impairment (MCI) or Alzheimer's disease.
The study is carried out as part of the GR2021 Priority project "Healthy Brains for life (Age 20-99): Digitally-enhanced personalized medicine study ANANEOS" and code numbered GR-00546 and it will look at the decentralized and remote assessment of the symptoms of preclinical stages in Alzheimer's disease and movement disorders, e.g. Parkinson's. For this study we are looking for participants aged over 45 without cognitive complaints or with subjective perception of cognitive decline or with mild cognitive complaints. Specific aims for the proposed study: a) to develop novel sensitive measures that can provide an early identification of those SCD and MCI individuals harboring AD pathology that are at high risk of cognitive worsening over time; b) to track pre-motor stages in Parkinson's disease and trials that enable active digital functional biomarkers; c) to track disease progression during pre-dementia and pre-motor stages in clinical practice and trials with measures that enable to capture subtle changes.
This study evaluates an educational brochure tailored to caregivers of people with Alzheimer's disease, Parkinson's disease dementia, Lewy body disease, frontotemporal dementia, and vascular disease dementia. The goal of the brochure is educating caregivers about the decreased ability to detect emotion and decreased empathy that can be seen in dementia, increasing caregiver competence in providing care, and teaching caregivers ways to manage over time that lessens burden and improves quality of life.
The aging of the United States (US) population will lead to a steep rise in Alzheimer disease (AD). There is an urgent need for novel therapies that may tackle this looming societal problem. People with Alzheimer disease have frequently evidence of vascular disease in the brain, and vascular disease can increase the risk of Alzheimer disease. Based on this finding, the investigators plan to expand the understanding of how vascular disease contributes to Alzheimer disease, hoping to identify novel target to modify the natural progression of the disease. The investigators will accomplish this goal by inviting 300 participants (with and without dementia) of the Northern Manhattan Study (NOMAS) to undergo a brain magnetic resonance imaging (MRI) and donate blood. Of the 300 participants enrolled, 60 participants will be randomly selected to undergo Aβ and tau positron emission tomography (PET) imaging. From the brain MRI, the investigators will obtain measurements of cerebrovascular disease and relate the to the risk of Alzheimer disease. With the blood, the investigators hope to identify measures of aging and inflammation that may predict changes noted in brain scan and identify people at a higher risk of dementia. The investigators will examine PET markers of inflammation and aging in the brain and how the markers relate to dementia.
The purpose of this open label study is to evaluate longer term tolerability and early efficacy of transcranial ultrasound in the treatment of patients with mild cognitive impairment or dementia.
Compensatory aids (e.g., alarms, calendars) play an important supporting role when completing everyday tasks (e.g., appointments, medication management), and there is a growing body of scientific work suggesting that compensatory training improves daily functioning. However, traditional paper-based calendars and to-do-lists have limitations related to accumulation of information, difficulty retrieving information, and remembering to complete activities. Such limitations may be overcome using a digital format through organized digital files, search functions, and alarms. This pilot project proposes to train older adults at risk for cognitive decline to use the Digital Memory Notebook (DMN), a tablet-based application (app), to support everyday functioning. The primary goal is to obtain preliminary evidence that a 6-week, individual and group-based DMN training intervention results in demonstrable changes in target behaviors (e.g., goal-directed DMN use to support everyday activities) among older adults with mild cognitive impairment (MCI) and subjective cognitive complaints (SCC). Participants will complete a curriculum involving 2-hour weekly sessions for 6-weeks. Each week will cover a specific function of the DMN and will include standardized goal-setting and weekly homework targets. Following the 6-week intervention, participants will continue to use the DMN app for 4-weeks to evaluate stability. Participants will complete a questionnaire packet 1 week prior to the 6-week intervention, 1 week after the 6-week intervention, and 5 weeks following the 6-week intervention. MCI and SCC participants will complete separate 6-week individual or group interventions spaced two months apart at UCD.
The recent development of a PET tracer,[18F]MK-6240(an[18F]tau imaging agent,CerveauTechnologies)that has high affinity for the human phosphorylated tau deposits in AD brain offers new opportunities to investigate tau pathology. The investigators will evaluate this imaging agent in individuals from families with a known Autosomal Dominant Alzheimer's Disease (ADAD) mutation. This study of tau PET using [18F]MK-6240 is performed in conjunction with DIAN and DIAN Extended Registry (DIAN-EXR).
Young-onset dementia (YOD) is a devastating condition, and it produces substantial psychosocial impacts on individual's functioning and family's care burden. Alzheimer's disease (AD) dementia is the most common type in YOD. Medication treatment Response was limited and unsatisfactory. In recent years, repetitive transcranial magnetic stimulation (rTMS) has been considered an alternative for the improvement of cognition in older patients with cognitive impairment. This study aims to examine the effects and potential mechanisms of theta-burst stimulation (TBS) on cognitive function in individuals with young-onset AD.
The investigators will conduct a study of brain positron emission tomography (PET) using 11C-PIB for the imaging of brain amyloid in 250 participants in the Multiethnic study of atherosclerosis (MESA) at Columbia University Irving Medical Center in New York City. Participants will be imaged only once with Pittsburgh Compound B (PIB) PET.
