Study on the Relationship Between Peripheral Blood miRNA and Risk and Severity of Alzheimer's Disease
Alzheimer's Disease, AD is a type of neurofibrillary tangles formed by the deposition of beta amyloid proteins within the nervous system cells and excessive phosphorylation of extracellular Tau proteins, NFTs are the main pathological features of central nervous system degeneration, also known as senile dementia. In addition, synaptic plasticity damage …
ADRC Clinical Cohort (Alzheimer's Disease)
The purpose of the study is to establish a clinical cohort for the Duke/UNC Alzheimer's Disease Research Center (ADRC). The cohort will be composed of subjects ages 25 to 44 at enrollment with normal cognition and subjects ages 45 to 80 at enrollment with normal cognition, mild cognitive impairment, or …
Prospective Cohort Study of Patients with Early Alzheimer's Disease Treated with Lecanemab
As the population increases and aging intensifies, cognitive disorders represented by Alzheimer's disease (AD) not only pose a severe threat to public health but also bring significant social and economic burdens. Previously, treatment options for Alzheimer's disease were very limited, mainly providing symptomatic relief with few available medications. Lecanemab, an …
A Longitudinal Study to Explore the Impact of Gut Microbiome on Brain Health in Alzheimer's Disease
Gut microbiota dysfunction is associated with Alzheimer's disease (AD). However, the potential modulatory mechanism remains unclear. Previous studies have shown that gut-derived metabolites short-chain fatty acids (SCFAs) may be the key mediators between gut microbiota and brain, participating in the modulatory pathway "gut microbiota-SCFAs-brain networks". In this project, high-throughput targeted …
Diagnostic Evaluation of Dementia with Lewy Bodies Using a Multimodal Approach
Dementia with Lewy body disease (DLB) is the second leading cause of degenerative cognitive disorder after Alzheimer's disease (AD). Its variable clinical expression makes diagnosis difficult. To date, there is no validated DLB diagnostic biomarker, despite several biomarkers in development (EEG, MRI, biology). Studies have shown that an improvement in …
Longitudinal Study for the Characterization of the Phases of Subjective Perception of Cognitive Decline and Mild Cognitive Impairment of Alzheimer's Disease.
Alzheimer's disease (AD) is the leading cause of dementia and its prevalence is estimated to exceed 100 million affects by 2050, becoming the main public health problem worldwide. AD is considered a clinicopathological entity characterized by a progressive cognitive impairment with affectation of memory and other cognitive domains, which underlies …
Distinguishing Between Alzheimer's Disease, Lewy Body Dementia, and Parkinson's Disease
The study is designed to characterize the clinical, neuropsychological, polysomnographic, and neuroimaging findings among subjects with Alzheimer's disease, Lewy Body dementia, and Parkinsons' Disease.
Autoimmune Features of Neurodegenerative Disorders
This study is being conducted to better understand the role of inflammation in Parkinson's disease (PD) and Alzheimer's disease (AD). The investigators plan to recruit 30 PD, 30 AD/Amnestic Mild Cognitive Impairment (aMCI), and 60 age matched healthy controls in this study to study the role of immune response in …
HOme-based Brain Monitoring With a GARment-EEG to Study Cognitive Decline in the Aging Population
This study will investigate the validity of the HOGAR EEG/PSG monitoring kit designed by Bitbrain as a tool for characterizing and assessing cognitive function in older adults, as well as for detecting and predicting cognitive decline. The kit consists of two EEG headbands and a mobile computing device that allows …
Tau Pet Imaging in the Aging Brain Cohort Dedicated to Diversity Study
We will conduct a Tau PET scan in cognitively normal older adults, enrolled in the Aging Brain Cohort Dedicated to Diversity Study (ABCD2-Tau) study at the University of Pennsylvania's Penn Memory Center/Alzheimer's Disease Core Center (PMC/ADC).Study duration will generally be a one-day study visit for PET imaging, but all subjects …
