4RTNI-2: 4-Repeat Tauopathy Neuroimaging Initiative – Cycle 2
This is an observational study which aims to determine the natural history of insoluble tau deposition as measured by PET scans in Progressive Supranuclear Palsy (PSP) and Corticobasal Degeneration (CBD) patients as compared to age-matched normal elders, quantify the longitudinal changes in cerebrospinal fluid as compared with other fluid biomarkers of neurodegeneration, measure ocular neuronal injury markers over time and to determine the clinical, MRI and neuronal injury marker correlates of tau deposition measured by PET.
Participants and their caregivers are asked to come in for 3 visits every 6 months for baseline, 6-month and 12-month visits. A select group of participants (those diagnosed to have oligo variant PSP and healthy controls) will be asked to come back for a 24-month visit. Each visit will take 2-3 full days to complete and will involve the following assessments: MRI scan, PET scan, blood draw, clinical assessment, neuropsychological assessments, eye testing, study partner interview and an optional lumbar puncture.
