Continuation of The Kronos Early Estrogen Prevention Study (KEEPS)
Alzheimer DementiaThe purpose of this study is to investigate how blood flow to the brain affects cognition in women who are postmenopausal, and how the use of hormone therapy early in menopause might change brain function. The testing in this study will add to the knowledge about brain aging in women. Researchers will determine if blood flow to the brain, brain structure, and cognition differences among women who took hormones in the past as part of Kronos Early Estrogen Prevention Study (KEEPS; NCT00154180), are currently taking hormones, or never took menopausal hormones.
The Mechanism of MicroRNAs Network in Alzheimer's Disease
Alzheimer DiseaseMicroRNAs network, such as MicRNA107 et al, regulate the pathology of Alzheimer's disease and the clinical validation in diagnosis AD.
Autologous Human Adipose-Derived Mesenchymal Stem Cells in Alzheimer's Disease
Alzheimer DiseaseThis is a single patient emergency expanded access clinical study to assess the safety of administering autologous AdMSCs to an incurable Alzheimer disease patient. The study subject will be evaluated for disease-associated severity according to symptoms, cognitive function, memory, and quality of life.
A Study of Comparing Rates of Dementia and Alzheimer's Disease in Participants Initiating Methotrexate...
DementiaAlzheimer DiseaseThe purpose of the study is to compare the risk of dementia in participants diagnosed with rheumatoid arthritis (RA) exposed to anti-tumor necrosis factor (TNF) therapy versus those exposed to methotrexate.
Autobiographical Memory
Alzheimer's DiseaseAutobiographical Memory2 moreThis study aims at the assessment of eye movement during autobiographical retrieval (i.e., retrieval of personal memories) in patients with Alzheimer's Disease.
Metacognition in Semantic Dementia: Comparison With Alzheimer's Disease
Semantic DementiaAlzheimer Disease1 moreThis study aims at exploring patients' ability to monitor their own memory performance depending on their primary deficit and the type of memory involved in the criterion task. The goal is to evaluate if semantic dementia (SD) and Alzheimer's disease (AD) differently affect patients' awareness of their memory abilities.
Juice Plus Supplement Clinical Trial
Cognitive ImpairmentAlzheimer Disease2 moreThe study is designed to determine whether encapsulated fruit and vegetable juice concentrates can improve biological indicators of cognitive and multiple dimensions of memory and learning.
Engagement 2.0 Forms of Consent for Data (re-)Use
Alzheimer DiseaseEarly Onset1 moreThe objective of this qualitative study is to create a better understanding of patients' mental model of health data engagement interfaces and tools (such as Dynamic Consent). The researchers will focus especially on those people who - plausibly - require adjusted communication particularities and interaction modalities due to a cognitive impairment stemming from a neurodegenerative disease. Taking into account the specific characteristics of patients with dementia, the goal of this study is to investigate how to communicate according to patients' personal skills and capabilities and identify both the proper support mechanisms for engagement 2.0 consent as well as feedback mechanisms (return of research results). Through a focus group & interview setup, this study will discern design requirements and propose design recommendations for the (future) development of health data engagement interfaces.
Multi-modality MRI Study on Prediction for Mild Cognitive Impairment Conversion
Mild Cognitive ImpairmentAlzheimer's DiseaseThe purpose of this study is to find the characteristics of mild cognitive impairment (MCI) using technology of Multi-Modality MRI , including structural MRI, functional MRI and diffusion tensor imaging(DTI). Then analyze the difference between progressive MCI (MCIp) and stable MCI (MCIs) and further construct the predictable classifier from MCI to Alzheimer's disease (AD) based on Multi-Modality MRI characteristics of MCI patients.
Retinal Neurodegeneration in Type 2 Diabetes as Biomarker for Alzheimer´s Disease
Retinal NeurodegenerationAlzheimer´s Disease1 moreA clear association between type 2 diabetes (T2D) and Alzheimer's disease (AD) has been reported. This association is independent of vascular impairment, and therefore, it could be attributed to neurodegeneration triggered or accelerated by diabetes itself. At present there are no methods to identify T2D patients at risk for developing AD. The retina shares many features with the brain and, therefore, has been suggested as an easily accessible way of examining pathology in the brain. In fact, many patients with AD present retinal abnormalities. However, the diagnosis of diabetes, a condition frequently associated with retinal neurodegeneration, has not been considered. On this basis, the final aim of this proposal is to identify diabetic patients at risk for developing AD based on the assessment of retinal neurodegeneration by means of non-invasive tests. Specific aims: 1) To compare the prevalence of morphological and functional abnormalities related to retinal neurodegeneration among three groups of T2D patients: patients with AD, patients with Mild Cognitive Impairment (MCI) and patients without AD or MCI. 2) To assess whether the retinal neurodegenerative features are related to severity of AD. 3) To explore whether the combined retinal neurodegeneration in diabetic patients with AD has a different functional and/or morphological pattern in comparison with neurodegeneration secondary to diabetes alone. Methods: Case-control study. Retinal neurodegeneration will be assessed by mutifocal electroretinogram (mfERG) and spectral domain optical coherence tomography (SD-OCT). The potential confounders will be considered in data analyses. Feasibility: A unique multidisciplinary consortium has been created in order to warrant the feasibility of the project Expected impact: This innovative approach will fill a gap that currently exist in the health care system and will reduce the economic burden associated with T2D patients with AD. In addition, this project would be the backbone for future prospective studies.
