CAPTURE ALS is a long-term data and biorepository platform that will facilitate future ALS research. CAPTURE ALS will provide the standardized systems and tools necessary to collect, store, and analyze vast amounts of multimodal information about ALS. These multimodal datasets and biosamples will be made available for use by researchers or industry across Canada and around the world in accordance with the CAPTURE ALS Data Sharing Policy to advance research on ALS.

In this observational study, participants with ALS and related disorders will be followed longitudinally over the course of a year to examine disease progression. Participants with ALS or a related disorder will have up to 5 in-person visits at screening, 0, 4, 8 and 12 months. Healthy controls are included as comparisons and will have 3 in-person visits at screening, 0 and 8 months. At each visit after screening, patients and healthy controls will undergo an MRI, neurocognitive and speech testing, clinical evaluations specific to ALS (ALSFRS-R, FVC, neurological exam, which are not completed by controls), answer questionnaires about their health and have biospecimens, including blood, saliva and optionally cerebrospinal fluid, collected.

Inclusion Criteria:

1. Has ALS, classified as definite, probable, laboratory-supported probable, or possible ALS according to the revised El Escorial criteria or a related neurodegenerative disorder including ALS-FTD, PLS, PMA or asymptomatic individuals with a known ALS mutation (as previously confirmed during regular clinical care)
2. Be of the age of majority in their province of residence/treatment
3. Have the cognitive capacity to provide informed consent

[HEALTHY CONTROLS]

Inclusion Criteria:

1. Be between the ages of 40-80 unless age matched to a patient (+/-3 years) who is already enrolled
2. Be the age of majority in their province of residence/treatment
3. Have the cognitive capacity to provide informed consent
4. Have proficiency in English of French to understand study instructions and respond to questionnaires

Exclusion Criteria:

1. A history of a neurological disease, including Central Nervous System disease (e.g., stroke, head injury, epilepsy) or Peripheral Nervous System disease (neuropathy, myopathy)
2. A history of psychiatric disease (e.g. depression, bipolar disease) that is clinically diagnosed and/or with the current use of psychiatric medications (e.g. antidepressants) for an indication of a psychiatric disease.
3. Subjects ineligible for an MRI due to a pacemaker or other contraindication according to local MRI policies of the study centre.
4. Significant claustrophobia that would prohibit an MRI (subjects will be required to lie in an MRI scanner for approximately one hour).

People living with ALS and related motor neuron diseases including ALS-Frontotemporal Dementia (ALS-FTD), Primary Lateral Sclerosis (PLS), Progressive Muscular Atrophy (PMA) and asymptomatic individuals with a known ALS mutation
