Epileptic Activity in Patients With Alzheimer's Disease and Lewy Body Dementia
Alzheimer DiseaseLewy Body Disease1 moreIn the current study, the investigators will examine the extent of subclinical epileptic activity in patients with Alzheimer's disease and patients with Lewy body dementia as compared to healthy elderly controls. The participants will wear a new device called "ear-EEG", which makes it possible to record EEG for longer periods of time while at home. Furthermore, the investigators want to investigate whether there is an association between subclinical epileptic activity and the cerebral blood flow as measured with functional MRI.
Epigenetic Biomarkers for Alzheimer's Disease
Alzheimer DiseaseAlzheimer's disease (AD) is a neurodegenerative disorder with no know cure. The pathogenesis of late onset AD (LOAD) is complex and multifactorial in nature, with multiple susceptibility genes and environmental factors at interplay. The objective of this study is to improve our understanding of the risk factors of LOAD by conducting an epigenome wide study within patients of LOAD contrasted against their cognitively normal siblings.
Study of Tau Imaging With the Use of [18F]MK-6240 Tracer
Alzheimer DiseaseThe recent development of a PET tracer,[18F]MK-6240(an[18F]tau imaging agent,CerveauTechnologies)that has high affinity for the human phosphorylated tau deposits in AD brain offers new opportunities to investigate tau pathology. The investigators will evaluate this imaging agent in individuals from families with a known Autosomal Dominant Alzheimer's Disease (ADAD) mutation. This study of tau PET using [18F]MK-6240 is performed in conjunction with DIAN and DIAN Extended Registry (DIAN-EXR).
Contributions of mTBI to Neurodegeneration Due to Chronic Traumatic Encephalopathy (CTE) and Alzheimer's...
Mild Traumatic Brain InjuryModerate Traumatic Brain Injury1 moreThis is a research study that aims to examine whether Veterans with mild Traumatic Brain Injuries are at risk for dementia by studying their memory, brain wave activity, brain structure and proteins that can be elevated after brain injury and in dementia.
Tau PET/CT Imaging in the Mismatch Prospective Cohort Study (MPC-TAU)
Alzheimer's DiseaseTo collect Tau PET/CT imaging in older adults diagnosed with Mild Cognitive Impairment (MCI) or Alzheimer's Disease (AD) in the Mismatch Prospective Cohort Study (MPC-Tau) study to determine relationship to clinical, cognitive, and other biomarker data. Findings from this study will likely provide insight into the phenotypic variability of Alzheimer's Disease and other related pathologies.
China Longitudinal Aging and Cognitive Impairment Study
AgingMild Cognitive Impairment2 moreThis is a multi-center longitudinal study that consists of five cohorts: cognitive normal aging (CN), Subjective cognitive impairment (SCI), mild cognitive impairment (MCI), Alzheimer's disease (AD) and vascular cognitive impairment (VCI). The goals of this study are as follow: 1.To establish longitudinal cohort study database containing comprehensive epidemiological data, neuropsychological test data, laboratory parameters, image data and biological samples. 2. To determine the risk factors of AD and other dementias. 3. To explore the conversion rates from CN to SCI, MCI or AD and the risk factors as well as biomarkers for the progression from CN to SCI, MCI or AD. 4. To explore and validate blood, CSF, urine, imaging and other biomarkers for the early detection and progression of AD.
A Diagnostic Test for Dementia With Lewy Bodies
MCI-ADEarly Stage Alzheimer's Disease2 moreThe Syn-D Study will be evaluating α-synuclein in patients with suspected MCI-AD and MCI-DLB. Using a simple diagnostic test will improve clinical accuracy in diagnosing, earlier diagnosis, and distinguish between neurodegenerative diseases.
Cohort of Patients With Alzheimer's Disease and Their Families.
Alzheimer DiseaseThis is the pilot phase of a longitudinal observational cohort study. The study includes family clusters comprised of a patient with Alzheimer's disease, an informal caregiver and at least one first-degree relative of the patient. The family clusters will be followed-up in expert memory centers and online in order to study risk and prognostic factors (including blood-based biomarkers) in the first-degree relatives and patients, respectively, as well as caregiver health, difficulties and needs. This pilot study is performed to assess the feasibility of conducting a larger-scale study.
Prevalence of Dementia and Delirium in Outpatient Clinics (DESTAN Trial)
Delirium in Old AgeDelirium Superimposed on Dementia1 moreThe aim of this study is to assess the prevalence and etiologic risk factors of delirium in outpatient geriatric patients and also hospitalized patients.
Arizona Alzheimer's Disease Research Center (ADRC)
Alzheimer DiseaseThe Arizona Alzheimer's Disease Research Center (ADRC) is the National Institute on Aging's (NIA's) first statewide AD Center (ADC), the only ADC in the Southwestern United States, and a leading example of statewide collaboration in biomedical research. It capitalizes on Arizona's strengths in brain imaging, genomics, computer science and biomathematics, the basic, cognitive and behavioral neurosciences, clinical, and neuropathological studies of AD, the discovery and evaluation of investigational treatments, and the study of normal cognitive aging.
