Hepatic encephalopathy other imaging findings

Electroencephalography may be helpful in the diagnosis of hepatic encephalopathy but, the findings in Electroencephalography are not specific for diagnosis of hepatic encephalopathy. Findings on an electroencephalography suggestive of hepatic encephalopathy include reduced frequency in the posterior derivations and increase in interhemispheric parietal relative coherence within the theta band.

• Electroencephalography may be helpful in the diagnosis of hepatic encephalopathy but, the findings in Electroencephalography are not specific for diagnosis of hepatic encephalopathy.^[1]
• Findings on an electroencephalography suggestive of hepatic encephalopathy include:^[2]
  • Reduced frequency in the posterior derivations
  • Increase in interhemispheric parietal relative coherence within the theta band

These findings could be seen in patients with child class C and in patients with a history of overt hepatic encephalopathy; they correlated with hyperammonemia and hyponatremia.^[2]

• Alterations in the electroencephalography are significantly associated with the severity of liver disease and hepatic encephalopathy In patients with cirrhosis.^[2]

• the electroencephalography is also helpful in the determining prognosis of patients with liver disease and hepatic encephalopathy.^[2]
