Abstract
Amyotrophic lateral sclerosis is a progressive degenerative neuromuscular disease of insidious onset. It involves upper and lower motor neurons and causes both spastic and atrophic muscular symptoms. More than one fourth of patients have complaints relating to the head and neck (bulbar palsy); thus, the otolaryngologist may be the first physician to see them. Predominant symptoms are slurred speech, hoarseness, dysphagia, and dyspnea. Muscular weakness, atrophy, and fasciculation are noted on examination. The course is relentless, and only 20% of patients survive five years after diagnosis.
