Survival in Incident Cases with Frontotemporal Lobar Degeneration: A Registry-Based Study.

Population-based registries represent a unique sample to estimate survival. The aim of the present study was to assess survival rates and predictors of outcome in incidental frontotemporal lobar degeneration (FTLD). Incident cases with FTLD, included between January 1, 2017 to December 31, 2017, have been followed for five years. Median survival was 8.16 years from disease onset and 5.38 years from diagnosis. Survival rates did not differ between phenotypes. Shorter disease duration from onset to diagnosis was associated with poorer outcome (p = 0.01). FTLD is a relatively homogeneous disease in terms of survival. Future multinational population-based studies are needed to confirm these findings. [ABSTRACT FROM AUTHOR]
