In addition to changed level of consciousness, the hallmark of hepatic encephalopathy on the physical examination is the presence of [[asterixis]]. This is detected by having the patient hold out his outstretched arms and hands and cock his wrists back. In the presence of asterixis, there is a non-synchronized, intermittent flapping motion at the wrists. Asterixis is not specific to hepatic encephalopathy. It may also be seen in states such as [[renal failure]] and [[carbon dioxide retention]]. | In addition to changed level of consciousness, the hallmark of hepatic encephalopathy on the physical examination is the presence of [[asterixis]].

Overview
In addition to changed level of consciousness, the hallmark of hepatic encephalopathy on the physical examination is the presence of asterixis. This is detected by having the patient hold out his outstretched arms and hands and cock his wrists back. In the presence of asterixis, there is a non-synchronized, intermittent flapping motion at the wrists. Asterixis is not specific to hepatic encephalopathy. It may also be seen in states such as renal failure and carbon dioxide retention.
