Which symptom is typically an early manifestation of hepatic encephalopathy?

• A. Sleep disturbances
• B. Jaundice
• C. Ascites
• D. Peripheral edema

Answer: (A)

Early brain dysfunction from liver failure causes neuropsychiatric changes, so disturbances of the sleep-wake cycle are often the first sign of hepatic encephalopathy. Patients may experience inverted or disrupted sleep, difficulty concentrating, irritability, or daytime sleepiness before other symptoms become apparent. As ammonia builds up, mental status worsens to confusion and cognitive slowing, with more overt changes like personality shifts and, later, asterixis. Jaundice, ascites, and edema reflect liver dysfunction or portal hypertension but aren’t early indicators of hepatic encephalopathy, which is why sleep disturbances are the best early manifestation.
