NCT07012993
The goal of this clinical trial is to evaluate an investigational ultralow dose PET imaging technique for Alzheimer's disease, mild cognitive impairment, other forms of dementia detection and monitoring. The main question it aims to answer is: Can the investigators optimize the timing, scan duration, and image reconstruction to reduce the radiation dose 10-100 fold of the current clinical standard? Participants will be injected with a radioactive tracer called 18F-Florbetapir or 18F-Flutemetamol and be imaged on a new type of high-sensitivity PET scanner for up to 3 hours
NCT06439992
The purpose of this research study is to determine the safety of a radiotracer 18F-Fluselenamyl using positron emission tomography (PET) imaging.
NCT04102514
The objective of this study is to compare the effectiveness of 2 intervention delivery strategies for increasing moderate physical activity (MPA), real-time group video conferencing (RGV) vs. enhanced usual care (EUC), in community dwelling adults with Alzheimer's diseases (AD) and their caregiver (dyads) over 18 mos. (6 mos. active, 6 mos. maintenance, 6 mos. no contact). The primary outcome is to compare total MPA (min/wk.), assessed using ActiGraph, in adults with AD from baseline to 6 mos. Secondary aims for the Adults with AD are to compare MPA (min/wk), sedentary time (min/wk.), percentage meeting 150 min/wk. goal, functional fitness, activities of daily living (basic/instrumental), quality of life, residential transitions, and cognitive function across 18 months between RGV and EUC. Secondary aims for the caregivers are to compare total MPA (min/wk.), sedentary time (min/wk.), functional fitness, quality of life, caregiver burden across 18 months between RGV and EUC. Additionally, as an exploratory aim, this study will evaluate the influence of process variables/participant characteristics on MPA in adults with AD and their caregiver across 6, 12 \& 18 mos.: age, sex, BMI, attendance (exercise/support sessions), use of recorded videos, PA self-monitoring, peer interactions during group sessions, caregiver support, type and quality of dyadic relationship, and number of caregivers.
