Amyotrophic lateral sclerosis (ALS) is a rare, progressive, and fatal neuromuscular disease for which there is currently no known cure. It typically manifests in mid-to-late adulthood and progresses rapidly with a median survival time of two to five years, though it can sometimes progress faster. It's currently diagnosed through a long process that can often take well over a year. We learn about a new technique developed at the nonprofit Brain Chemistry Labs in Jackson, Wyoming that can diagnose ALS with a simple blood test with 97% accuracy.
