Which sign is commonly seen in hepatic encephalopathy but not a primary liver disease sign?

• A. Jaundice
• B. Ascites
• C. Asterixis
• D. Hepatomegaly

Answer: (C)

Hepatic encephalopathy causes brain dysfunction due to toxins like ammonia building up when the liver can’t detoxify properly. The classic sign you see from this neurologic involvement is asterixis, the flapping tremor felt when you ask a patient to hold their arms out with wrists extended. It reflects impaired cerebral function and is a hallmark of hepatic encephalopathy, signaling neuropsychic changes rather than primary liver pathology. In contrast, jaundice, ascites, and hepatomegaly are direct manifestations of liver disease itself—high bilirubin causing yellowing, fluid accumulation from portal hypertension, and an enlarged liver from inflammation or damage. These signs point to liver pathology rather than the brain dysfunction seen in hepatic encephalopathy.
