Amyotrophic lateral sclerosis (ALS) is an adult-onset disease characterized by progressive motor neuron degeneration that results in muscle atrophy, spasticity, hyperreflexia, paralysis, and eventually death.¹ The average patient lifespan ranges from 3 to 5 years after diagnosis.² Numerous potential factors may contribute to disease, including genetics,³ exposure to environmental toxins,⁴ and trauma to the central nervous system (CNS),^5,6 but in the sporadic form of ALS, a single cause of disease has yet to be identified. Instead, sporadic ALS may result from multiple factors that each increase disease susceptibility.⁷
