Neurologic Stem Cell Treatment Study
This is a human clinical study involving the isolation of autologous bone marrow derived stem cells (BMSC) and transfer to the vascular system and inferior 1/3 of the nasal passages in order to determine if such a treatment will provide improvement in neurologic function for patients with certain neurologic conditions. …
A Study That Collects Participant Data and Biospecimens to Analyze Pathogenic Exosomes That Mediate Increased Vascular Dementia Risk in Individuals With Herpes Zoster.
The purpose of this observational research study is to study if patients with herpes zoster, also known as Shingles, have a higher risk of vascular dysfunction (problems with blood vessels, including stroke) and vascular dementia (problems with mental decline as a result of decreased blood flow to the brain) compared …
Molecular Neuroimaging of Neuroinflammation in Neurodegenerative Dementias
Neuroinflammation is increasingly implicated as a potential critical pathogenic mechanism in a variety of neurologic and psychiatric disorders. This study will use hybrid PET/MRI imaging to evaluate neuroinflammation and its relationship to cerebral perfusion in frontotemporal dementia (FTD). Patients with FTD will be recruited from the Cognitive Neurology and Aging …
Retinal Vessel Leakage in Cerebral Small Vessel Disease
The goal of this observational study is to learn about leakage from retinal vessels in cerebral small vessel disease. The main questions it aims to answer are: Does retinal vessel leakage occur in cerebral small vessel disease? If it does, is the severity of retinal vessel leakage similar to the …
Identification of Neuroinflammation and Neuroimaging Biomarkers Through Data Driven Artificial Intelligence Techniques for Unraveling the Heterogeneity of Aged Subjects at Risk of Dementia and to Better Inform Prevention Strategies
SCD and MCI are very heterogeneous conditions, which can be prodromal to different types of dementia. The application of data driven clustering methods on neuroimaging and inflammatory data aims at identifying the features characterizing subgroups of subjects at high risk of developing overt dementia. This approach promises to develop tailored …
SV2A & TSPO PET Imaging Measures to Reveal Mechanisms of HIV Neuropathogenesis During Antiretroviral Therapy
The purpose of this study is to longitudinally characterize and evaluate changes in synaptic density in the brain using novel positron-emission tomography (PET) scans; magnetic resonance imaging (MRI), and clinical laboratory markers associated with HIV-related injury in the central nervous system. This study will test hypotheses relating to the presence …
Global Collaborative Research on Establishing a Korean Cognitive Aging Cohort
The goal of this observational study is to learn how daily emotional stress affects cognitive function and inflammation in community-dwelling older adults aged 60 and older in Seoul, Republic of Korea. The main questions it aims to answer are: Does daily psychological stress measured in real-time affect short-term and long-term …
A Natural History Study of Preclinical Genetic Creutzfeldt-Jakob Disease (CJD)
Creutzfeldt-Jakob Disease (CJD) is the most common prion disease in humans causing a rapidly progressive neurological decline and dementia and is invariably fatal. The familial forms (genetic CJD, gCJD) are caused by mutations in the PRNP gene encoding for the prion protein (PrP). In Israel, there is a large cluster …
A Multimodal Approach for Clinical Diagnosis and Treatment of Primary Progressive Aphasia, MAINSTREAM ID:3430931
Primary Progressive Aphasia (PPA) is a syndrome due to different neurodegenerative disorders selectively disrupting language functions. PPA specialist care is underdeveloped. There are very few specialists (neurologists, psychiatrists, neuropsychologists and speech therapists) and few hospitals- or community-based services dedicated to diagnosis and continuing care. Currently, healthcare systems struggle to provide …
Semantic Rehabilitation for Patients With Primary Progressive Semantic Aphasia
This project aims to measure the effect of a semantic rehabilitation protocol for patients with primary progressive semantic aphasia and using the SCED methodology.
