[Amyotrophic lateral sclerosis that begins with voice and deglution alterations].

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. In bulbar forms of Amyotrophic Lateral Sclerosis, voice and/or swallowing difficulties are often the initial signs of disturbance. Predominant symptoms are slurred speech, hoarseness, dysphagia, and dyspnea. Muscular weakness, atrophy, and fasciculation are noted on examination. We show a case and revise bibliography.
