A disturbance of sleep is recognized as one of the early signs of hepatic encephalopathy. Reversal of sleep rhythm, drowziness and lethargy are classic signs of this disease. Sleep disturbance and excessive daytime somnolence are common in patients with cirrhosis. It was estimated that up to 70% of individuals with cirrhosis (regardless of etiology) experience sleep disturbances [4]. Difficulty falling asleep and a shift in sleep schedule toward the latter part of the night, which might be result in daytime sleepiness, are commonly reported findings in patients with hepatic cirrhosis without encephalopathy [4].
