Amyotrophic lateral sclerosis (ALS) is a disease that results in the progressive deterioration and loss of function of the motor neurons in the brain and spinal cord, leading to paralysis. ALS affects approximately 16,000 individuals, with a prognosis for survival of 2 to 5 years. There are 2 types of ALS differentiated by genetics: familial and sporadic (idiopathic). Diagnosis is determined by excluding other conditions and utilizing clinical examinations, laboratory tests, and nerve conduction/electromyography studies. Due to the collection of information from the participation of patients with ALS in registries, biomarkers and genes associated with ALS have been discovered. The best practices for the management of ALS include an interdisciplinary approach aimed at addressing the physical and psychological needs and desires of patients and their families and caregivers.
