Blood Biomarker of Alzheimer's Disease (AD)
Alzheimer DiseaseCurrently, no cures or disease modifying therapies exist for Alzheimer's disease (AD). This is partially due to the inability to detect the disease before it has progressed to a stage where there are clinical manifestations. The identification and validation of high throughput biomarkers to measure disease progression (as well as identify pre-clinical disease onset) is critical to the development of disease-modifying or even preventative therapies. In this study, we are testing a blood biomarker for stratification of Alzheimer's disease patients and healthy volunteers. This study may lead to future blood tests that may help earlier diagnosis of Alzheimer's disease and detect the disease progression.

The multidisciplinary team is comprised of trained behavioral neurologists, social workers, advanced practice providers, primary medical team and nurse coordinators.
Evaluating the Relationship Between Tau PET Imaging and CSF Biomarkers of AD (Alzheimer Disease)...
Alzheimer DiseaseThe purpose of this research study is to evaluate a new radioactive compound used in positron emission tomography (PET) scans in identifying tau tangles (a certain protein that might be associated with Alzheimer's disease) in the brain, and if the amount of tau tangles in the brain has a relationship to cerebrospinal fluid (CSF) biomarkers and cognitive status. This study involves a PET scans using the radioactive compound, F 18 T807 for measurement of tau deposition. This radioactive compound is not approved by the United States Food and Drug Administration (FDA). An MRI will be conducted if one has not been completed completed within the past 12 months under a related research study. Participants will be asked about their medical history, family history, surgical history, and current medications. We will evaluate history of traumatic brain injury (TBI) using the Ohio State University Traumatic Brain Injury Identification (OSU TBI-ID) Method. This will take approximately 10 minutes. Participants will be asked to undergo a Mini Mental State Examination (MMSE), which will last approximately 5-10 minutes. Additionally, participants may be invited to undergo optional brain PET imaging with 2-deoxy-2-[18F]fluoro-D-glucose fludeoxyglucose (18F-FDG), for measurement of the cerebral metabolic rate of glucose consumption. At the time of the initial T807-PET study, participants will be asked if they are willing to undergo repeat T807-PET imaging at least 2 years after the initial study. This follow up study is optional, and participation in the study and initial T807-PET imaging will not be contingent on agreeing to the 2-year follow up study.
Synaptic Injury and Functional Connectivity in Alzheimer's Disease
Alzheimer DiseaseLate OnsetThe purpose of this study is to examine cross-sectional associations between CSF markers of synaptic injury (Ng and SNAP-25) and functional connectivity in default and semantic memory networks using 3T- fMRI in individuals with MCI (i.e. the earliest clinically detectable stage of cognitive impairment) due to AD or mild AD dementia (CDR 0.5-1; n=20) and cognitively normal controls (CDR 0; n=20).
Connected Solution of Assistance Dedicated to Caregivers and People With Alzheimer's Disease or...
Alzheimer DiseaseAlzheimer's disease and related diseases (ADRD) are a major public health issue. In France, nearly 900,000 people have ADRD, which represents about 70% of dementia cases, and the expected prevalence for 2020 is 1.2 million. Patients with ADRD have cognitive, behavioral and functional impairments that lead to progressive impairment of quality of life and autonomy. Maintaining them at home depends predominantly on their caregivers, mainly family, spouse or child. By definition, the caregiver is "the person who provides partial or total support to an elderly dependent person or a person with a disability in the vicinity of the victim for the activities of daily life". The investment of caregivers is therefore both human and financial, representing a greater or lesser burden. This burden can significantly affect their quality of life. Indeed, studies have shown that caregivers suffer from depletion, anxiety, depression and sleep disorders resulting in a deterioration of their health, leading them to greater care consumption. They would be more prone to cardiovascular diseases and cancer. A review of the literature from 2009 examined 66 studies evaluating the contribution of various technologies targeting demented patients and their caregivers. Of these, only 10 dealt with independence at home and the well-being of the patient and his / her caregiver. The main limitations of these studies are the small samples (ranging from 1 to 6 patients), the degree of cognitive degradation (mainly moderately severe) and the lack of standardized assessment. Although new technologies promise powerful home-based solutions, studies evaluating their efficacy for patients with ADRD and their caregivers remain scarce and fragile at the level of evidence due to methodological biases.
Trial to Reduce Antimicrobial Use In Nursing Home Residents With Alzheimer's Disease and Other Dementias...
DementiaInfection1 moreThis is a 52-month study (8 months preparation; 36 months to conduct the trial; 8 months data analyses and manuscript preparation) of a cluster randomized controlled trial (RCT) of an intervention to improve infection management for suspected UTIs and LRIs among residents with advanced dementia (N=480; N=240/arm) living in NHs (N=24; N=12/arm). The NH is the unit of randomization as the intervention must be delivered at the facility level to avoid contamination and because this is how it would be employed in the real-world. Analyses will be at the patient level.

Comparing Smartphone Technology and a Memory Strategy on Improving Prospective Memory in Alzheimer's...
Alzheimer DiseaseCognitive Impairment3 moreAlzheimer's disease is a debilitating condition for patients and their caregivers marked by hallmark cognitive symptoms (e.g., memory loss) as well as an impact on quality of life. Researchers and clinicians are learning that a specific type of memory, called prospective memory, may be particularly affected in mild Alzheimer's disease. Prospective memory is memory for future intentions, goals, and chores, and the loss of the neurocognitive processes supporting prospective memory may reduce independent functioning (e.g., medication adherence). The current study investigates a technology-based intervention to assist participants with their daily prospective memory tasks. Participants with mild cognitive impairment and mild Alzheimer's disease will be trained to use a smartphone for four weeks. Smartphone acceptability, usability, and overall user experience will be measured. Furthermore, participants will be tested on completion of daily prospective memory tasks. In one group, participants will train to use the smartphone personal assistant reminder system, which reminds participants of their goals, tasks, and chores at the appropriate time or location. In a comparison group, participants will also carry a smartphone but will train to use a memory strategy in which they verbalize external cues to remind them to perform their goals, tasks, and chores. The goal of this research is to inform whether smartphone technology or a memory strategy can be used to reduce memory burden and improve daily, independent functioning in participants with mild Alzheimer's disease.
Enriching Clinical Trials Requiring Amyloid Positivity With Practice Effects
Alzheimer DiseaseMild Cognitive ImpairmentThe primary objective of this study is to demonstrate that individuals with low short-term practice effects (STPE) on cognitive testing are more likely to be identified as "positive" on amyloid imaging than individuals with high STPE. STPE may also inform us about other AD-related biomarkers, including hippocampal volumes, functional connectivity, and APOE status. By realizing the aims of this pragmatic study, we hope to be able to offer more economical and efficient screening of potential participants for clinical trials, which would reduce participant burden and financial costs.
