This is an observational study called CRiALS, which means researchers will be carefully watching and collecting information from people to better understand Amyotrophic Lateral Sclerosis (ALS) and related brain diseases. The study aims to learn more about how ALS develops, find ways to measure the disease (biomarkers), and understand its full progression from early stages to later stages. There are no specific drugs or interventions being tested in this study. You may be able to join if you are at least 18 years old and have ALS or a related neurodegenerative disease, are an unaffected family member of someone with familial ALS (ALS that runs in families), or are a healthy control. The main goal for this study is to recruit participants, and this is measured annually. The current recruitment status is unclear.
