Quality improvement in neurology: Amyotrophic lateral sclerosis quality measures Report of the Quality Measurement and Reporting Subcommittee of the American Academy of Neurology

Amyotrophic lateral sclerosis (ALS) is a lethal, progressive neurodegenerative disease characterized by loss of motor neurons.¹ Patients with ALS lose function in the limbs, speech, swallowing, and breathing muscles. The cause of the disease is still not known for most patients. Approximately 25,000 people in the United States have ALS, and 5,000 people are diagnosed with ALS annually in the United States.¹ Most patients die from respiratory failure 2 to 5 years after onset of symptoms. Cognitive dysfunction is seen in 20 to 50% of patients.² The disease burden for patients and caregivers is enormous. The average cost of care has been estimated at $50,000 per patient per year.<sup>3
