Multicenter Longitudinal Imaging in ALS for Disease Biomarker Development
This is a multi-site study of ALS participants and healthy controls who will undergo brain and cervical spine MRIs and NfL blood testing at up-to 4 time points over the course of a year. The primary goal is to identify objective biomarkers of disease progression that are biologically relevant, linearly progressive, and sensitive to change.
⁃ For participants with ALS:
• \< 36 months since onset of symptoms
• Definite, probable, lab supported-probable or possible ALS by El Escorial criteria OR definite, probable or possible ALS per Awaji-Shima Criteria
• Forced vital capacity within the last 90 days ≥ 60% of the predicted value
• Able to consent for themselves
• Able to read and speak English
• Clear of any contraindications for MRI
