Filter by:The purpose of this research study is to determine the safety of a radiotracer 18F-Fluselenamyl using positron emission tomography (PET) imaging. The investigators will first complete whole-body PET dosimetry studies in healthy adult normal volunteers to calculate the actual radiation dose of each human organ and determine the allowable dose for a human subject when receiving a single dose for a PET scan. Second, imaging of the brain and neck will be completed in a wide range of ages of healthy adult normal control participants and participants with mild cognitive impairment, both male and females to characterize 18F-Fluselenamyl uptake in the brain, its binding to beta-amyloid plaques, and radiolabeled metabolite will be completed. Amyloid is a protein related to dementia of Alzheimer's disease. 11C-PIB PET imaging along with MRI will also be completed in the same participants and the data will be compared with 18F-Fluselenmayl. 11C-PIB and 18F-Fluselenamyl both bind to beta-amyloid plaques. Finally, a comparison of the normal control participants to patients with Alzheimer's disease will be completed.
This study will look at the effects of lemborexant on Alzheimer's disease biomarkers found in the cerebrospinal fluid (CSF) and blood in individuals who are poor sleepers
Gamma brain activity is crucial for cognitive function and intra-brain communication. Gamma frequency stimulation via transcranial alternating current stimulation(tACS) might alleviate memory deficits on both animal models of Alzheimer's disease (AD) and clinical trial. The study aims to assess the safety and efficacy of tACS on cognitive function and modulating neurophysiology in patients with AD.
This trial will assess feasibility of a non-pharmacological intervention for persons living with Alzheimer's disease and related dementias (ADRD) to improve behavioral and psychiatric symptoms of dementia and functional performance. Using a two-arm, prospective randomized controlled trial, 38 dyads (person with ADRD and caregiver) will complete an 8-week telehealth occupational therapy intervention provided via Zoom with caregivers and persons with dementia or receive an active control with 8 telehealth sessions to discuss publicly available caregiver education with a non-clinical research assistant.
The purpose of this study is to pilot test the feasibility, acceptability, and preliminary efficacy of a clinically useful, inclusive dementia-enhanced training and tool for use by home hospice clinicians to improve care and support for Black and White patients with dementia and their family caregivers. The investigators expect family caregivers of clinicians in the intervention group will report less caregiver burden (primary outcome) than caregivers of clinicians in the control group. The investigators expect that, compared to clinicians in the control group (usual care), clinicians in the intervention group (receive the training and use the tool) will demonstrate more knowledge of dementia-related caregiving issues (secondary outcomes). In exploratory analyses, the investigators expect family caregivers will report greater self-efficacy and preparedness, and that patients of clinicians in the intervention group will experience fewer live discharges than family caregivers of patients of clinicians in the control group.
The purpose of this study is to know the effectiveness of an adapted therapeutic exercise program and its comparison with non-invasive neuromodulation through the NESA device, and both treatments with a control group, to improve sleep disturbances and cognitive function in patients with dementia, and improves the quality of life of their caregivers.
The goal of this study is to observe the outcomes of a semantic recognition task in Alzheimer Disease and discuss what this might add to clinical practice.
The overall objective of this project is to characterize the spatiotemporal dynamics of brain oscillations underpinning autobiographical memory (ABM) and the modulation of the memory network using non-invasive brain stimulation.
This study will compare smartphone usage data between three groups of patients diagnosed with either a memory complaint, mild cognitive decline, or Alzheimer's disease.
The DPPOS AD/ADRD project will address the overarching question: What are the determinants and the nature of cognitive impairment among persons with pre-diabetes (PreD) and type 2 diabetes (T2D), who are a high-risk group for cognitive impairment and represent a large fraction of the United States (US) population? This U19 proposal addresses the National Alzheimer's Project Act goal to "prevent, halt, or reverse AD" in the high-risk group of persons with pre-diabetes and type 2 diabetes, who represent over half of the population aged 60 years and older in the US.
