Inclusion Criteria - Patient with ALS, ALS-FTD or Similar Neurodegenerative Disease: * Clinical diagnosis of possible, laboratory-supported probable, probable or definite ALS according to modified eL Escorial criteria, suspected ALS according to original el Escorial criteria, or diagnosis of a similar neurodegenerative disorder. * Willing to provide consent, or assent, if physically unable to consent owing to disease-related muscle weakness.
