Brief Summary:

Recently two staging systems have been proposed for amyotrophic lateral sclerosis (ALS), based on clinical milestones The King's college clinical staging system (1) and ALS Milano-Torino Staging (ALS-MITOS) (2). Further research to validate and develop an accurate staging system in different populations will improve our understanding of its pathogenesis, disease activity and progression.

General objective : To validate the two previously proposed staging system and to test the interest of considering Neurofilament biomarkers in these systems.

Specific objectives: 1) To validate the two classification systems in an independent cohort of patients with ALS followed-up in the ALS expert center of Limoges (France) 2) To assess the interest of Nf biomarkers to predict neurological decline


Condition or disease
Amyotrophic Lateral Sclerosis

Detailed Description:

Amyotrophic lateral sclerosis (ALS) is a rare, fatal neurodegenerative disease of the human motor system. Recently two new staging systems have been proposed for ALS, based on clinical milestones related also to the spreading pattern of the disease (1,2). Furthermore, biomarker development is still an essential component of future therapeutic development in ALS. Thus, it is also important to acknowledge the value of biomarker research in supporting or revealing fundamental pathophysiological mechanisms in ALS.

The proposed staging systems: have been recently tested in two independent cohorts (3,4) with results that were not fully consistent (ii) did not considered the potential value of biomarkers.

Primary Outcome Measures :
  1. To validate the two previously proposed staging system and to develop an accurate staging system in ALS considering Neurofilament (Nf) biomarkers. [ Time Frame: 2 years ]
    To validate the two previously proposed staging system and to develop an accurate staging system in ALS considering Neurofilament (Nf) biomarkers


Biospecimen Retention:   Samples Without DNA
Blood samples will be collected from ALS incident cases. Neurofilaments levels will be determined in the plasma using ELISA Method
