Which symptom indicates progression to more advanced hepatic encephalopathy?

• A. Seizures
• B. Disorientation
• C. Asterixis
• D. Reversal of sleep-wake cycle

Answer: (D)

Hepatic encephalopathy is a spectrum of brain dysfunction caused by liver failure and toxin buildup, so signs progress from subtle cognitive changes to confusion and coma as cerebral function becomes more globally impaired. Reversal of the sleep-wake cycle—sleeping more during the day and being awake at night—reflects a significant disruption of brain regulation and indicates that the disease has advanced beyond mild changes to more pronounced, widespread cerebral involvement. This circadian pattern shift signals that the encephalopathy has progressed toward the more serious stages.

Seizures aren’t the hallmark of progression in hepatic encephalopathy and aren’t as specific to advancing disease. Asterixis can occur with hepatic encephalopathy but may appear earlier in the course and doesn’t alone signify the deepest level of involvement.
