Summary The Centers for Disease Control and Prevention (CDC) National Amyotrophic Lateral Sclerosis (ALS) Registry is the first national registry for a chronic neurologic disease in the U.S. and uses a combination of case finding methods including administrative healthcare data and patient self-registration. Analysis shows that the methods used by the National ALS Registry provide for an excellent methodological foundation for estimating ALS prevalence in a large country with fragmented healthcare, and can be used for tracking prevalence of other neurological diseases.
