Clinical Information
  • A constellation of signs and symptoms characterized by changes in personality, consciousness, and reflexes, resulting from neuropsychiatric abnormalities secondary to liver failure without evidence of other brain disease.
  • A syndrome characterized by central nervous system dysfunction in association with liver failure, including portal-systemic shunts. Clinical features include lethargy and confusion (frequently progressing to coma); asterixis; nystagmus, pathologic; brisk oculovestibular reflexes; decorticate and decerebrate posturing; muscle spasticity; and bilateral extensor plantar reflexes (see reflex, babinski). Electroencephalography may demonstrate triphasic waves. (from Adams et al., Principles of Neurology, 6th ed, pp1117-20; plum & posner, diagnosis of stupor and coma, 3rd ed, p222-5)
