Answer

The symptoms of hepatic encephalopathy may range from mild to severe and may be observed in as many as 70% of patients with cirrhosis. Symptoms are graded on the following scale:

  • Grade 0 - Subclinical; normal mental status but minimal changes in memory, concentration, intellectual function, coordination

  • Grade 1 - Mild confusion, euphoria or depression, decreased attention, slowing of ability to perform mental tasks, irritability, disorder of sleep pattern (ie, inverted sleep cycle)

  • Grade 2 - Drowsiness, lethargy, gross deficits in ability to perform mental tasks, obvious personality changes, inappropriate behavior, intermittent disorientation (usually with regard to time)

  • Grade 3 - Somnolent, but arousable state; inability to perform mental tasks; disorientation with regard to time and place; marked confusion; amnesia; occasional fits of rage; speech is present but incomprehensible

  • Grade 4 - Coma, with or without response to painful stimuli
