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.
Study I7S-MC-HBEH (HBEH) is a multicenter, randomized (i.e. study in which people are assigned at random (by chance alone) to receive one of several clinical interventions), double-blind (i.e., neither the participant nor the person evaluating for the study knows what group the participant has been assigned to), parallel-group (i.e., a type of study where two groups of treatments, A and B, are given so that one group receives only A while another group receives only B.), placebo-controlled (i.e. one group will receive the study drug and the other will receive a substance that has no therapeutic effect, also known as placebo), fixed-dosage (i.e., the dosage will not change during the course of the study), Phase 2a study (i.e., a trial with the objective of assessing what dose is more effective in treating symptoms.) comparing various dosages of LY3154207 administered orally once a day with placebo over 12 weeks in subjects with mild-to-moderate Parkinson disease dementia (PDD).
The study includes a Screening Period (Visits 1 to 2) of a minimum of 7 days and up to 14 days, a 14-day Pretreatment Period (Visits 2 to 3), a 12-week Treatment Period (Visits 3 to 11), and a 14-day Safety Follow-Up Period (Visit 12).
Your participation will last about 17-18 weeks.
The purpose of this study is to find out how LY3154207 compares with placebo in treating memory and thinking problems in individuals with mild-to-moderate Parkinson's disease dementia.
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.
