Filter by:The goal of this observational study is to learn about the pathophysiology characterization and evolutionary patterns of Alzheimer's disease (AD) in South China older adults. The primary purposes are as follows: 1. The prevalence and characteristics of AD in South China's aging population 2. Identify novel biomarkers and neuroimaging techniques for early detection and intervention of AD 3. Supporting and fertilizing novel approaches and techniques for early diagnosis and intervention of AD Participants will undergo cognitive assessments, blood sample collection, and genetic testing. Some will undergo CSF collection, stool sample collection, MRI scanning, Aβ PET scanning, and tau PET scanning.
[18F]Florbetazine ([18F]92) is a molecularly targeted imaging agent for Aβ protein with a novel diaryl-azine scaffold. It has shown specific binding affinity to Aβ aggregates in postmortem human AD brains and excellent brain pharmacokinetic properties with little non-specific retention in white matter in animal studies and a limited number of patients with Alzheimer's Disease (AD). The purpose of the current study is to examine the binding properties of [18F]Florbetazine in human subjects and to compare the cortical and white matter binding with [11C]PiB or [18F]Florbetapir in the same subjects. Imaging of the brain will be completed in healthy adult normal control participants and participants with cognitive impairment (including probable AD and dementia due to other conditions) to characterize [18F]Florbetazine uptake in the brain and its binding properties. [11C]PIB or [18F]Florbetapir PET imaging along with MRI will be completed in the same participants and the data will be compared with 18F-[18F]Florbetazine.
The study tests the effect of the ATNC MDD-V1 on Alzheimer patients' cognitive function. The ATNC MDD-V1 uses non-invasive stimulation of both magnetic and cognitive training.
The aim of this study is to assess the efficacy and safety of GSK4527226 in participants with early Alzheimer's Disease (AD) (including mild cognitive impairment [MCI] and mild dementia due to AD) of 2 dose levels of GSK4527226 compared to placebo.
The primary purpose of this study is to identify participants with or without symptoms of Alzheimer's Disease (AD) that are at high risk for brain amyloid pathology using blood-based biomarkers.
Developing and validating an early digitalized recognition device and multimodal warning model for Alzheimer's disease, and establishing a precision transcranial ultrasound stimulation intervention system.
- Phase 1A SAD: Five or more cohorts of 8 healthy volunteers (HVs) will receive a single IV bolus injection of study drug or placebo. The first 4 cohorts will be male only. The last cohort will be repeated with the max safe dose of the previous cohorts in healthy elderly subjects (male and female of non childbearing potential, > 50years) - Phase 1B MAD: Two or more cohorts of 8 male and female HVs will receive multiple (4) IV bolus injections of study drug or placebo every 72 hours.
The primary purpose of this study is to confirm the clinical efficacy and mechanism of action of GV-971, and identify incidence of known adverse reactions in long-term use and observe new adverse reactions, providing more guidance for clinical use.
The goal of this clinical trial is to test a mobile application amongst caregiver's supporting patients diagnosed with Alzheimer's Disease and Related Dementias (ADRD). The main question it aims to answer is: Will caregivers supporting patients diagnosed with ADRD utilize a mobile application to routinely report symptoms of the patients they care for?
Aim 2 will investigate the effect of 3 different light exposure lengths on sleep, mood and agitation in persons with Alzheimer's disease. Participants will be randomly assigned to one of three conditions of light exposure: 1) 2-h morning light exposure; 2) 4-h morning light exposure; and 3) all day light exposure.
