This multicenter study will enroll 300 members of familial Frontotemporal Dementia (FTD) families across 8 experienced FTD research centers with a known mutation in MAPT, PGRN, or C9ORF72 (100 mutation carriers with mild dementia or minimally symptomatic yet non-demented, 100 asymptomatic mutation carriers, and 100 clinically normal relatives who are non-mutation carriers) to obtain annual assessments including T1-MRI, FLAIR, diffusion tensor imaging (DTI), ASL perfusion (ASLp), intrinsic connectivity functional MRI (icfMRI), MR spectroscopy (MRS), CSF, blood, and behavioral, neuropsychological and functional assessment, for a total of three assessments per participant.
A primary goal of this study is to identify the most robust and reliable methods to track disease progression in familial FTD so that disease-modifying therapeutic trials can be designed appropriately.
