Presumption of service connection for amyotrophic lateral sclerosis. Final rule
Abstract:
This document adopts as a final rule the interim final rule amending the Department of Veterans Affairs (VA) adjudication regulations to establish a presumption of service connection for amyotrophic lateral sclerosis (ALS) for any veteran who develops the disease at any time after separation from service. This amendment implements the decision by the Secretary of Veterans Affairs to establish such a presumption based on a November 2006 report by the National Academy of Sciences Institute of Medicine on the association between active service and ALS.
