Though exceedingly rare, some people diagnosed with amyotrophic lateral sclerosis (ALS) partially or fully recover from the lethal neurodegenerative disease.

To that end, researchers launched a study of ALS recovery patients and found certain genetic factors that appear to protect against the disease's typical assault on motor neurons.
