Hepatic Encephalopathy - Diagnosis
Research News and Information
Definition of 'Hepatic Encephalopathy'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) |

Patients with minimal hepatic encephalopathy (MHE) have impaired driving skills, but association of MHE with motor vehicle crashes is unclear. Standard psychometric tests (SPT) or inhibitory control test (ICT) can be used to diagnose MHE. The aim ... Read more...
Toxic and acquired metabolic encephalopathies: MRI appearance.
30 Aug 2009 OBJECTIVE: The differential diagnosis of patients presenting with acute encephalopathy is broad. Imaging can help in narrowing the differential in many cases. We pictorially review the more classic MRI features of several acute toxic and acquired ... Read more...
Cranial MRI in acute hyperammonemic encephalopathy.
30 Jul 2009 Cranial magnetic resonance imaging was performed in three cases of acute hyperammonemic encephalopathy with three diverse etiologies: infantile citrullinemia, acute hepatic encephalopathy, and proximal urea cycle disorder. All three patients ... Read more...
