Changes to Average Survival of Patients With Amyotrophic Lateral Sclerosis (1995-2018): Results From the Piemonte and Valle d'Aosta Registry.

Background And Objectives: The average survival of patients with amyotrophic lateral sclerosis (ALS) ranges from 2 to 5 years from symptom onset. However, it remains unclear whether this estimate has improved over time. The objective of this study was to analyze the survival trend of a large population-based cohort of patients with ALS over a 24-year period.

Brain Metabolic Features of FUS-ALS: A 2-[F]FDG-PET Study.

Objective: We aimed at evaluating the brain metabolic features of fused in sarcoma amyotrophic lateral sclerosis (FUS-ALS) compared with sporadic ALS (sALS), using 2-[fluorine-18] fluoro-2-deoxy-D-glucose positron emission tomography (2-[F]FDG-PET).

Methods: We employed the 2-sample t-test model of SPM12, implemented in MATLAB, to compare 12 FUS-ALS cases with 40 healthy controls (HC) and 48 sALS, randomly collected from the series of patients who underwent brain 2-[F]FDG-PET at the ALS Center of Turin (Italy) at diagnosis from 2009 to 2019. In the comparisons between cases and HC, we included age at PET and sex as covariates.
