    Diseases of the nervous system
Clinical Information
  • A motor neuron disease marked by progressive weakness of the muscles innervated by cranial nerves of the lower brain stem. Clinical manifestations include dysarthria, dysphagia, facial weakness, tongue weakness, and fasciculations of the tongue and facial muscles. The adult form of the disease is marked initially by bulbar weakness which progresses to involve motor neurons throughout the neuroaxis. Eventually this condition may become indistinguishable from amyotrophic lateral sclerosis. Fazio-londe syndrome is an inherited form of this illness which occurs in children and young adults. (Adams et al., Principles of Neurology, 6th ed, p1091; brain 1992 dec;115(pt 6):1889-1900)
  • A progressive motor neuron disorder affecting the muscles which are innervated by cranial nerves of the lower brain stem. Signs and symptoms include difficulties in chewing and swallowing, dysarthria, and weakness of the facial muscles and tongue.
ICD-10-CM G12.22 is grouped within Diagnostic Related Group(s) (MS-DRG v37.0):
  • 056 Degenerative nervous system disorders with mcc
  • 057 Degenerative nervous system disorders without mcc
