Evaluating the Relationship Between Tau PET Imaging and CSF Biomarkers of AD in Humans
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The 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.
