French-German Cohort Study to Determine Factors Associated With Weight Loss in Amyotrophic Lateral Sclerosis

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease. Studies have shown the importance of weight loss at the time of diagnosis and during the progression of the disease. However, the pathophysiological mechanisms behind weight loss remain unknown. Identifying these mechanisms could make it possible to propose an effective therapeutic strategy against weight loss for ALS patients, which could improve their survival and quality of life. In this context, the investigators are proposing an innovative multidisciplinary project aimed at structuring a large Franco-German cohort to identify the markers associated with weight loss in ALS. Participants will undergo high quality standard care for ALS patients. In addition, participants will be asked to respond different questionnaires and blood samples will be taken for analysis to identify biological markers.
