Brief Summary

The objectives of the study are to; (1) estimate the change in disease -related cognitive decline over 1 year on a battery of cognitive tests administered to participants with early-stage symptomatic Behavioral Variant Frontotemporal Dementia (bvFTD) phenotypic variant; (2) identify the cognitive test or brief battery of cognitive tests which are the most sensitive to detect bvFTD progression; (3) determine the optimal schedule of administration of cognitive tests to detect bvFTD progression; (4) evaluate the relationship between cognitive tests and measures of behavior, function, caregiver's burden, quality of life (QOL); and (5) obtain blood samples for genetic and exploratory biomarkers correlations.
