We are recruiting individuals between the ages of 6 months and 85 years of age that have Down syndrome along with their mothers and siblings.
Each participant will provide a blood sample during for research purposes aimed at identifying novel biomarkers for health.
We will also gather some basic health information about senses, habits, exercise level and smoking/vaping exposures.
Loss of smell may affect over 20% of the population, specifically among older age groups and can result in significant health impacts. Smell loss can substantially affect an individual's overall well-being and quality of life. The purpose of this study is to evaluate the impacts of smell loss on neurologic disease (such as Alzheimer's and dementia) and on the risk of death over a 10-year period. We hypothesize that decreased sense of smell is associated with development of neurodegenerative disease and mortality. Participants in this study will fill out an electronic questionnaire (about 30 minutes long) at study entry, and a shortened electronic questionnaire (about 15 minutes long) every year after that for 10 years. No in-person visits are needed.
Alcohol Use Disorder (AUD) is a risk factor for Alzheimer's Disease (AD), but more research is needed to identify the potential mechanisms underlying this risk. The present study will use fMRI to examine brain network profiles in mid-life AUD. The goal is to develop techniques to assess risk for Alzheimer's Disease and related dementias. Participation includes cognitive testing and MRI scanning.
Candidates for this study may or may not report disturbances in odor perception as their primary reason for seeking treatment at MUSC. This study is designed to collect long term, observational data from patients who are being treated with routine clinical care in health clinics at MUSC. Data from clinical questionnaires will be de-identified and stored in a database.
The purpose of this study is to use neuroimaging to understand how networks in the brain change over time. Although the single most significant risk factor for developing Alzheimer's disease (AD) is age, the neurobiological processes underlying the transition from normal aging to AD are not well understood. Our group of researchers has developed ways to use MRI to detect small changes in certain parts of the brain. We will use neuroimaging to understand how the connections in the brain change over time in healthy aging. The goal is to discover which brain changes are present in healthy aging so that future studies can assess the risk for developing Alzheimer's Disease.
Participants will have two study visits (about 2 years apart) where they will undergo tests to assess mental function, fill out questionnaires, and undergo a blood draw, brain MRI and PET scan. At the second visit, participants will not repeat the blood draw and a PET scan.
Participants are required to have a Co-Participant accompany them for the first portion of each visit. This individual must be a reliable informant that has contact with the participant at least once per week.
This study will use neuroimaging to understand how the connections in the brain change in Alzheimer's Disease. Changes will also be examined in individuals with mild cognitive impairment and healthy aging. The goal is to discover which brain changes are present in healthy aging and MCI so that future studies can assess the risk for developing Alzheimer's Disease. The study involves blood draw, cognitive testing, MRI, PET scanning, and a 1-year follow-up visit to repeat cognitive testing and MRI scanning.
Alzheimer's disease and the isolation it produces imposes a heavy burden on informal caregivers (CG) of Veterans who are persons with dementia (PWD), who carry greater burden than those caring for persons with other chronic diseases. This feasibilty study will test a mobile application (APP) on a mini-iPad designed for caregivers of community-dwelling Veterans who are PWD in comparison with Web-based informational materials. Building on story-telling interventions effective in other chronic diseases, this feasibilty study proposes Story-Call as a newly-developed mobile application that records, archives, and presents 30/60-second videos by caregivers and professionals, who share brief stories about how they have handled common dementia home-care situations, such as "She wants to go home!" A qualitative component will categorize themes from stories and in 2 phases collect: 1) perceptions from follow-up phone interviews with CG participants; and 2) focus groups with Advisory Group and VA stakeholders as a process evaluation of APP appeal, use, impact, and cultural tailoring. The expected outcomes will examine if CGs find that the APP-recorded stories decrease perceived CG burden and increase social support as efficacy, while confirming feasibility in recruitment, acceptability, practicality, increased adaptation to dementia care, and use of community resources for future scaling up and testing.
