Amyotrophic lateral sclerosis (ALS) is a progressive, degenerative neurological disease. 1 It is the most common form of motor neuron disease (MND), but still considered rare, with a global incidence of approximately 2/100,000 persons. 2 ALS onset typically occurs in later life, peaking between 50 and 75 years of age, affecting persons of both sexes and all ethnicities. 1 The consequences of ALS can be devastating for those affected and their families. Disease progression is rapid, with only half of patients living longer than three years following diagnosis. 3
